Frequently Asked Questions - SHERPA OLIMPIA SPLENDID

Can I install the SHERPA heat pump myself?

No, installation must be carried out exclusively by a qualified and approved installer. Any installation by non-specialized personnel voids the warranty and may present electrical risks or refrigerant leaks.

What type of refrigerant is used and is it dangerous?

The refrigerant is R410A, a fluorinated greenhouse gas (GWP=1975). It must not be released into the atmosphere. In case of a leak, ventilate the room as the gas can become toxic when in contact with a flame.

How to clean the indoor and outdoor units?

The user can clean the exterior of the units with a soft dry cloth. For cleaning filters or exchangers, contact a professional. Before any operation, cut off the main power supply.

What to do if the device displays an alarm code (e.g. P03, FL)?

Check the alarm table in the manual. Codes such as FL (water flow fault) or P03 (abnormal discharge temperature) require verification by an installer. You can reset the alarm by pressing the decrease key for 5 seconds.

Can the device operate in heating mode in extreme cold?

Yes, the heat pump can operate down to -20°C. Its performance decreases with outdoor temperature, but it ensures a COP greater than 2 even at -7°C. Auxiliary heating (resistance or boiler) can be used as a supplement.

Should I drain the hydraulic circuit in case of prolonged shutdown?

Yes, if the device is not used for a long period and negative temperatures are possible, you must drain the circuit or add antifreeze (ethylene glycol up to 35%). Consult technical service for the procedure.

What is the recommended water pressure in the circuit?

The operating pressure should be between 1 and 2 bar (pump off). Do not exceed 2.5 bar. Use the pressure gauge on the control panel to check. If the pressure drops below 0.5 bar, the pump may cavitate.

How to set the target temperature?

Use the user interface (controller) on the indoor unit. Press the i key to access the menu, select SAn (sanitary) or SéT (heating/cooling), hold the i key and use the arrows to change the value.

What is the estimated lifespan of the heat pump?

With regular maintenance and proper installation, the device can operate for more than 15 years. The warranty depends on usage conditions and maintenance by an approved professional.

Can I use extension cords for power supply?

No, it is strictly forbidden to use extension cords or adapters. The device must be connected to a dedicated circuit with a residual current circuit breaker suitable for the power (see sizing table in the manual).

INSTALLATION OF THE INTERNAL UNIT (FIG. 4)

PREARRANGE:

• 4 M10 plugs for wall fixing.
• an area with sufficient free lateral space to allow removal of the cover
• a water drain in the vicinity
• a water supply in the vicinity
• a conforming power supply in the vicinity
• fixing elements that are appropriate for that kind of weight

INSTALLATION

MODE D'INSTALLATION

The internal unit must always be fixed to a wall within the home and in the room chosen by the client.

Thanks to the high level of acoustic isolation of the device, the choice of the room into which the client may install the internal unit is very broad.

The internal unit must be fixed to the wall at the height of a person using M10 plugs and ensuring that sufficient free space is left on either side.

Panel opening: front, upper and side

• Open the door (fig. 5 ref. A) simultaneously pressing with the thumbs on the knurled parts. At this point the door will open downwards.
• Remove the plastic side guards (fig. 5 ref. B).
• Unscrew the two fixing screws (fig. 5 ref. C) from the control panel.
• Remove the inspection panel by pulling it towards you.

INSTALLATION OF THE EXTERNAL UNIT

The maximum length of the connection lines to the internal unit must be 50m in each sense (for lengths greater than 30m it will be necessary to top up the R410A load with 40g for each meter). Furthermore, the maximum difference in height between the internal and external unit must not exceed the figures indicated in the table on Page 18.

It is very important that the installation place be chosen with extreme care in order to ensure adequate protection of the device against impact or possible consequential damage.

The external unit can be installed onto specific wall fixing brackets (using the appropriate wall assembly kit that can be ordered separately as an accessory) or else onto a concrete base.

WARNING

• Mount the external unit in a position that is capable of supporting the weight.
• Choose a place that is adequately ventilated and in which the external temperature in summer does not exceed 45^ C .
• Leave sufficient free space around the device in order to avoid recycling and to facilitate the maintenance operations.
• Underneath the device prearrange a layer of gravel for the drainage of the defrosting water.
• When installed in a location with high snow fall, mount the support of the device at a height that is greater than the maximum level of snow.
• When installed in a location of severe snow storms, prearrange a sheath for the device.

Appropriate brackets for wall fixing are available upon request (optional).

In this case prearrange vibration damping blocks in order to prevent the transmission of the vibrations.

• Use concrete or a similar material to make the base, and ensure good drainage.
  Ordinarily, ensure a base height of 5cm or more. If a drain pipe is used, or for use in cold-weather regions, ensure a height of 15cm or more at the feet on both sides of the unit. (In this case, leave clearance below the unit for the drain pipe, and to prevent freezing of drainage water in cold-weather regions).

Open the casing on the side for access to the connectors (fig. 7).

IMPORTANT:

Do not make the connections using normal hydraulic pipes that could contain residues of flashing, dirt or water and that could damage the parts inside the unit and interfere with proper operation.

Use only special copper pipes for cooling, that are supplied clean and sealed at the ends.

After cutting the proper lengths, seal the ends immediately on the roll and cut piece.

Pipes for refrigeration with preinsulation can also be used.

Only use pipes with the a diameter suitable for the dimensions described in the technical data sheets.

• Plan the route of the pipeline so as to reduce the length and number of bends as much as possible for best performance of the system. The maximum length of the connection line of the internal unit must be 50m in each sense (for lengths greater than 30 m it will be necessary to top up the R410A load with 40g for each meter). Furthermore, the maximum difference in height between the internal and external unit must not exceed the amounts indicated in the table on Page 18.
• Fasten a cable raceway to the wall (possibly with internal partitioning) of suitable size for the pipes and electric wires to pass through.

BRANCHEMENTS FRIGORIFIQUES

• Cut the sections of pipe leaving an extra 3-4 cm on the ends.
  IMPORTANT: use a wheel pipe cutter only to cut the pipes (fig. 8) clamping it in short lengths so as not to crush the pipe.
  NEVER USE A NORMAL HANDSAW, scraps could fall inside the pipe and enter the circuitry of the system, damaging the parts severely (fig. 9 A).
• Remove possible burrs with the special tool.

IMPORTANT: immediately after cutting and deburring the pipes, seal the ends with insulating tape.

If you do not use preinsulated pipes, they must be insulated as follows:

• material: polyurethane foam with closed cells
• max. coefficient of transmission : 0,45 W/ (Kx m^2 ) or 0.39 kcal/(hxCx m^2 )
• minimum thickness: 6 mm (for liquid pipes)
• minimum thickness: 9 mm (for gas pipes)

Do not place both pipes in the same sheath, as this would jeopardize the proper operation of the system (fig. 9 B).
- Bind any joints in the sheath securely with insulating tape.

F

• Before flaring the pipe ends, insert the fastening nut (fig. 10 A).
  Flare the pipe ends using the special tool. Take care not to break, crack or split the pipe (fig. 10 B).

• Lubricate the connecting thread with oil for coolant (DO NOT USE ANY OTHER TYPE OF LUBRICANT).

• Screw the pipe nut manually on the connecting thread.
• Tighten using a wrench to hold the threaded part of the connector, so as to avoid twisting the pipe, and a dynamometric wrench on the nut (fig. 11) calibrated with the following values depending on the size of the pipe:
• Diameter 3/8" 34 N/m < tightening torque < 42 N/m
• Diameter 5 / 8'' 68 N/m < tightening torque < 82 N/m

Length of the 3/8" and 5/8" connection pipes without complementary load of gas 5m to 30m

Maximum allowable length 50 m

Complementary load of R410A per meter of pipe between 30 and 50 m 40 g/m

Limit of elevation difference between the 2 units. Outdoor unit is placed higher 30m

Limit of elevation difference between the 2 units. Outdoor unit is placed lower 15m

Tests and inspection

Once the pipes have been connected it is necessary to check that the cooling system has a perfect seal.

To perform the operations described below it is necessary to use a pressure gauge unit that is specific for R410A and a vacuum pump with a minimum flow rate of 40l/min (fig.12):

1 - Unscrew the closure cap of the gas line service joint (fig. 14 ref. C).
2 - Connect the vacuum pump and the pressure gauge unit using flexible pipes with a 5/16" fitting to the gas line service joint (fig.13).
3 - Start the pump and open the taps of the pressure gauge unit.
4 - Reduce the pressure to -101kPa (-755mmHg, -1bar).
5 - Keep the pressure reduced for at least 1 hour.
6 - Close the taps of the pressure gauge unit and switch off the pump.
7 - After 5 minutes and only if the pressure has remained at -101kPa (-755mmHg, -1bar), go to point 8. If the pressure within the circuit has risen to a value greater than -101kPa (-755mmHg, -1bar) it will be necessary to search for the leak (using a soapy solution or leak detector), once identified and repaired, it will be necessary to restart from point 3.

If the length of the pipe is greater than 30m it is necessary to top up the R410A gas load by 40g per meter. Refer to paragraph 2.4.2 and then restart from point 8.

8 - With a 4mm hexagonal socket wrench open the liquid valve stem completely.
9 - With a 5mm hexagonal socket wrench open the gas valve stem completely.
10 - Remove the flexible loading pipe connected to the gas pipe service joint.
11 - Reposition the cap of the gas pipe service joint and fix it with a torsion wrench or an open-end wrench.
12 - Reposition the caps of the service valves stems of both the gas and liquid and tighten them.

If the length of the pipe is greater than 30m it is necessary to top up the R410A gas load by 40g per meter.

• Connect a cylinder of R410A cooling gas to the pressure gauge unit and place it onto an analytical balance.

• Open the taps of the pressure gauge unit.
• Open the tap of the cylinder liquid.
• Load the required amount of coolant.
• Close the taps of the cylinder and pressure gauge unit and disconnect the cylinder.
• Record the length of the pipes and the quantity of coolant added onto the label of the product (within the panel).

HYDRAULIC CONNECTIONS

The choice and installation of components is decided by the installer, who must operate in compliance with good workmanship and current legislation. Before connecting the pipes, ensure they are free from stones, grit, rust, debris or any foreign bodies that may damage the system.

It is good practice to create a by-pass in the system so that the appliance does not have to be disconnected in order to wash the plate heat exchanger.

The connecting pipes must be supported, so that their weight does not rest on the appliance.

The hydraulic connections should be completed by installing:

• a 3 way valve to divert water to the sanitary circuit. This valve must enable water to circulate during the diversion, to prevent untimely triggering of the alarm FL.
  We recommend using the 3 point valve with 90^ movement available in the appliance accessories (B0606 suited to both 1"and 1"1/4 connections). This valve has 2 microswitches with 6(2)A contacts for controlling the pumps, zone valves, etc.;
• a metallic mesh filter (available as accessory B0607 1" for Sherpa 8,12 and 15 and B0608 1"1/4 for Sherpa 18) on the return line of the system in an easily accessible position for routine maintenance;
• air relief valves at the highest points of the pipes;
• flexible elastic joints;
• on/off valves.

The hydraulic connections are positioned in the lower part of the unit (fig. 16). Installation onto walls must follow the indications described in paragraph 2.2 "INSTALLATION OF THE INTERNAL UNIT".

M 1" water delivery (1 1/4" for 18)
R 1" water return (1 1/4" for 18)
L 3/8" liquid line
A 5 / 8" suction line
E electrical connections

The nominal minimum diameter of the connection pipes must be 1^ (1 1/4" for model 18). To allow the maintenance and repair operations it is indispensable that each hydraulic connection is fitted with respective manual closing valves.

The maximum pressure losses allowed are those defined in the technical data paragraph. Should more head be necessary due to high pressure loss in the system an external pump must be added with relative inertial vessel.

The distribution pipes for the cooled water must be adequately insulated with expanded polyethylene or similar material with a thickness of at least 13mm .

Even the interception valve, the curves and union joints must be adequately insulated. To avoid pockets of air inside the circuit we strongly recommend including automatic or manual breather devices in all points (high pipes, siphons etc) where air can accumulate.

Always check the thermal difference between the system inlet and outlet - which must be between 4 - 7^ - checking the parameter t1 and t3 with the i key (see paragraph 3.2.2). If the thermal difference is less than 4^ , set a lower speed for the circulator.

If, on the contrary, the difference is greater than 7^ , check that all of the valves present on the system are open and possibly add an external pump to increase the water flow. If the mains water pressure is more than 3 bar, install a pressure reducer on the supply.

Upon initial start-up, the specialized technician will have to obtain the reference values of the system's water using appropriate test kits.

REFERENCE VALUES OF SYSTEM'S WATER

pH: 6.5 to 7.8

Electric conductivity: between 250 and 800~ S / cm

Total hardness: between 5 and 20^

Total iron: below 0.2 ppm

Manganese: below 0.05 ppm

Chlorides: below 250 ppm

Sulphur ions: absent

Ammonium ions: absent

If the total hardness is above 20^ or some of the make-up water reference values are not within the indicated limits, contact our pre-sales service to determine the treatments to be used.

Bore or groundwater not from water supply system should always be carefully analysed and if necessary treated with appropriate systems. If installing a softener, in addition to following the manufacturer's guidelines, adjust the hardness of the outlet water to no lower than 5^ (also run pH and salinity tests) and check the concentration of chlorides at outlet after regeneration of resins.

Warning: do not introduce acids into the wash circuit.

In the case of possible freezing, empty the system and introduce an antifreeze liquid in a proportion that is appropriate for the minimum temperatures that can be reached.

Solutions of water and ethylene glycol used as heat-transfer liquids in place of water cause a reduction in the performance of the unit. Add a maximum of 35% of ethylene glycol (protection equivalent to as low as -20^) to the water.

Ions ammonium:absents

Once the hydraulic connections have been completed the system will have to be filled. It will then be necessary to simultaneously release the air from the inside of the pipes and device itself.

During these operations, the machine must be disconnected from the mains power supply.

If an external auxiliary pump is used it must also be switched off.

The working pressure of the system must not exceed 1.5bar with the pump switched off. To check any possible leaks from the system when setting up we suggest you increase the test pressure and then reduce it successively it to reach the working pressure.

Once all the electrical connections have been made and the circulation pump is activated, check that there are no pockets of air in the system. If this happens, stop the pump, release the air and re-start, repeating the procedure until it is all cleared. To avoid dangerous cavitations that could damage the pump and make the entire system less efficient, the inlet pressure with the pump switched on must not be less than 0.6 bar, measurable with the manometer on the device.

If during the first startup, alarm FL appears after the circulator has started, check that: the valves in the system are open, there is at least one user with the circuit open, the external sieve filter is not clogged, there are no air bubbles in the circuit, the water pressure in the system is correct and the circulator is not blocked. Eventually, rearm the alarm and at the same time unblock the circulator (fig. 17).

REMPLISSAGE DE L'INSTALLATION

Before carrying out any intervention, make sure that the electrical power supply is switched off. For electrical connections, refer to the wiring diagram in the following paragraph, especially concerning the power supply terminal strip.

The power supply voltage must be equal to that shown in the technical data table.

The wires must have pointer terminals with a cross section proportionate to the connecting wires before their insertion into the terminal strip.

The power supply must be adequately dimensioned to avoid voltage drops or overheating of the wires or other devices along the line. For data relating to sizing, refer to the table below (fig. 18).

It must be possible to isolate the power line must be from the mains supply of the building with the thermomagnetic circuit breaker suitable for the absorption of the machine with differential relay with a maximum calibration equal to that indicated by the individual electrical standards.

Check that during the compressor operation the electrical power voltage corresponds to the nominal value +/- 10%.

It is forbidden to use the gas or water pipes to earth the device.

The manufacturer is not responsible for any damage resulting from the lack of an earth connection or the failure to observe that indicated in the wiring diagrams.

The connection cable must be sized as indicated in table 18 on page 26. However, a cable with a minimum of 4mm^2 is recommended. The cable must be double-insulated, multi-polar mod. H05VVF for indoor applications and mod. H07RNF for outdoor applications in a conduit.

Electrical connection of the external unit

The electrical power supply of the external unit (single-phase or three-phase) is to be connected together with the electrical power supply clamps of the internal unit using cables of an appropriate size in order to avoid voltage drops or overheating.

CONNECTIONS TO THE TERMINAL STRIP (FIG. 20)

clamps 1-2: inlet for the probe that detects the temperature of the domestic boiler water (supplied and to be connected by the installer to a maximum distance of 50m ).

clamps 3-4-5: summer/winter room thermostat connection (purchased separately and to be connected by the installer) Clamps 3 and 4 enable the summer operation while clamps 3 and 5 the winter one. N.B: when the contact 3-5 is open, the production of hot domestic water is inhibited.

external thermostat connection for integration of element to be calibrated between 0 and -15^ (available as accessory B0567).

clamps 8-9: configurable inlet for the activation of the anti-Legionella function (to purchase separately, together with a timer, and to be connected by the installer).

Through the activation of the anti-Legionella function, the adjuster is able to conduct the thermal disinfection procedures autonomously on domestic hot water systems equipped with recirculation, considerably reducing the risk of the presence and proliferation of the bacteria responsible for Legionella.

The numerous variables related to the creation of the systems into which our products may be installed do not allow the total exclusion of the risk.

Activation of the disinfection function can be performed by connecting a timer to the inlet that has a default value set for 2 am the night between Sunday and Monday; as statistically this is a time with a low probability of employment on behalf of the users.

The duration of the action is determined by the characteristics of the system. The Legionella bacteria react differently depending upon the maximum temperature reached within the ring and, with the increase of temperature, the duration time decreases.

The default parameters set in the device are: temperature setting >60^ for a duration of 2 hours but other settings are also possible taking into consideration the following rules:

• above 70^ disinfection lasts 30 minutes.
• between 65^ and 70^ disinfection lasts 60 minutes,
• between 60^ and 65^ disinfection lasts 120 minutes,
• between 57.5^ and 60^ disinfection lasts 180 minutes,
• between 55^ C and 57.5^ C disinfection lasts 240 minutes.

The adjuster indicates the execution of the anti-Legendella function through the flashing of the LED , it performs a check of the effective execution of the action on the basis of the preset parameters and then eventually exits the function after a timeout of 5 hours.

During execution of the anti-Legionella function the cooling and heating requirements of the system are not satisfied.

In order to avoid getting burnt when hot water is taken during the thermal disinfection phase, it is advisable to introduce a safety device against burns on every system.

clamps 10-1: external unit control panel connection (performed in the factory)

clamps 12-13: external unit serial connection (installer's responsibility). Respect the polarity of the terminals!

If a voltage of 230V is accidentally applied, the 0.5A fuse of the external unit will trip in order to protect the electronic board (fig. 19).

clamps 14-15: 230Vpower supply (max 1A) for the support boiler.

terminals 15-16-17

power supply 230V (max 3A) for 2 or 3 point diverter valve in the system/sanitary circuit (available as accessory B0606).

AUXILIARY HEATER MANAGEMENT (RESISTANCE OR SUPPORT BOILER)

When in heating mode, the controller performs an automatic integration of the unit in heat pump whenever the water temperature is below 30^^* by activating the contactor K1 that runs the auxiliary heater (only in the units fitted with support resistances) and the exclusion of the support boiler (clamps 14-15).

*This threshold can be modified by the C.A.T. (Technical Assistance Centre).

In the units equipped with support resistances it is possible to connect the three stages (2, 4 or 6kW depending upon the requirements and the power available.

Consult the table of power absorption for the various conditions and add the power of the resistances connected in order to determine the size of the electrical system.

In the single-phase units the electrical absorption increases each stage connected by 9A.

In the three-phase units the electrical absorption increases by 9A on each phase connected to the resistance; when only one or two stages are connected, the absorption will be 9A, even on the neutral.

Adequately size the electrical connector of the neutral.

Solely for the units equipped with a support, using the RO switch it is possible to disenable the heat pump so that only the integration operates. In the units that do not have a support resistance, the boiler exclusion will be activated.

For domestic use, above 50^^* the switch from heat pump / auxiliary heater is performed automatically. The contactor K1 is therefore activated and runs the auxiliary heater (only in the units fitted with a support resistance) and the support boiler exclusion (clamps 14-15) while the operation of the external unit is simultaneously stopped.

• This threshold can be modified by the C.A.T. (Technical Assistance Centre). The function is signalled by the flashing LED on the user interface.

By connecting an external thermostat to the clamps 6 and 7 it is possible to perform an integration of the unit while in pump mode (also performed through the activation of the contactor K1) below the setpoint set on the thermostat. This function is performed during both heating as well as during domestic operation and is not indicated on the user interface.

Inside the collector where the resistance is fitted there is a sensor for the thermostat TS calibrated at 80^ that proceeds to mechanically disconnect (by opening the magnetothermic switch Q2 through the releasing device C) the electrical power supply to the resistances if the threshold is exceeded.

HANDING OVER THE SYSTEM

When all the checks and controls for the correct operation of the system have been completed, the installer must show the user the basic functional features, the instructions for use and the ordinary maintenance.

The system consists of a metallic structure that encloses, in a series of panels, all the operational parts.

From the outside, only the control panel can be accessed (fig. 21).

The panel includes the following devices:

A Unit master cut-off switch.
B External heat pump operation warning light.

In the units with a resistance there is a RO switch that disables the operation of the external unit (support resistance or boiler) and should only be used for certain requirements and only in the heating or domestic functions.

Do not turn off the switch while in cooling mode.

C The controller that adjusts and coordinates all the main functions of the unit. This device is for adjusting and controlling all the main functions of the unit.
During normal operation the water temperature detected by probe t2 positioned inside the domestic boiler is indicated on the display.
D The summer/stop/winter selector through which it is possible to set the summer, winter mode or to switch-off the circulation pump during those periods where the device is not used.
E The pressure gauge displays the system water pressure. It allows the checking of the correct water pressure inside the circuit; the values must be between 1 and 2 bar.

UTILISATION ET ENTRETIEN

ELEMENTS COMPOSANT LE SYSTEME ET DESCRIPTION DES PIECES

The external unit control panel is not a remote control: it is solely used to adjust the setpoint of the return water temperature for just the heating mode and to indicate the technical parameters or alarms. Programming of some of the parameters must be performed exclusively by an authorised and qualified installer.

CONTROLLER SETTINGS

User interface

The interface (fig.23) normally displays the temperature of the water in the domestic boiler and allows performing all of the operations related to the use of the instrument and in particular:

Set the stand by/on operation mode;
- Display and rearm the alarm situations;
- Check the state of the resources (setpoint, temperature, etc).

Apart from what is described in this chapter, there are many other settings possible which imply an in depth knowledge of the device and system to which it is connected in order to prevent serious damage to the device.

It is equipped with a 3 digit display for displaying the temperatures or parameters and any alarms, 6 LEDs that indicate the comma (between the second and third digit, indicated only for the measurements below 20^ ), summer/winter state, domestic request, external unit ON and alarm signalling.

On the basis of the readings from the probes of the system return temperature (T1) and domestic water (T2), for the setpoints and state of the inlets, the software automatically performs the thermostatic adjustments:

The production of domestic water, which has priority over the other adjustments, imposes heat pump operation of the external unit until the desired setpoint is reached (factory set at 40^ and adjustable between 30 and 50^ ) and simultaneously activates the 3-way valve in order to hydraulically divert the hot water produced into the domestic water boiler.

This adjustment is indicated by the switching on of the appropriate LED

10 Touche VENTILATION

Sans fonction.

11 Touche OUTILS

The cooling operation selected with the summer/winter selector positioned on the control panel imposes the production of cold water to the setpoint set at 12^ on the return water (adjustable between 10 and 20^ ).

This adjustment is indicated by the switching on of the appropriate LED.

The heating operation selected with the summer/winter selector positioned on the control panel acts in order to operate the external unit in heat pump mode to the setpoint set at 45^ on the return water (adjustable between 20 and 50^ ).

To exploit the external unit modulation algorithm it is necessary to set the setpoint ensuring that the one of the adjustor is always greater or equal to the one set on the control panel of the external unit.

This adjustment is indicated by the switching-on of the appropriate LED.

The external unit is enabled every time that there is a thermostatic request of the controller and is indicated by the switching-on of the LED.

The adjustments are mutually excluding and the setting is memorised even in the event of a power failure.

Displays

During normal operation the display will indicate the temperature detected or else the following indications:

FL Intervention of the flow meter connected to DI1

Lo Low temperature alarm detected by the probe T3

E1 Failure of the probe T1

hi High temperature alarm detected by probe T3

E2 Failure of the probe T2

ALr Intervention in a time of one of the alarms for no.>ASM

E3 Failure of the probe T3

oFF Adjuster on stand-by

Opening of the inlet to which the differential pressure switch is connected and which performs the flow meter operation causes the alarm FL to signal once a period of 10 seconds have lapsed.

Through the system inlet temperature probe 13 which is positioned at the outlet of the plate exchanger, the low temperature (antifreeze 5^ indicated by the prompt Lo on the display) and high temperature (80^,hi on the display) alarms are managed.

Furthermore, the E1, E2 and E3 signals are also possible in the case of failure or incorrect detection of the three temperature probes. There is no antifreeze protection foreseen for the device on stand-by.

Any alarm signal is accompanied by the block of the outlets and by the switching on of the LED as well as the buzzer and is subject to the maximum hourly frequency check (3 alarms per hour).

Below this limit rearming of the alarm will be automatic while if the value is exceeded rearming will be manual (in this case the alarm signal will be alternated with the signal ALr that will indicate the definitive block of the device).

To silence the buzzer press the i key.

When the cause of the alarm ceases, the LED will switch-off.

To reset the alarm press the key for 5 seconds.

• Request that the customer be present for the test run. Explain the contents of the instruction manual, and then have the customer actually operate the system.
• Be sure to give the instruction manual and warranty certificate to the customer.
• When replacing the control PCB, be sure to make all the same settings on the new PCB as were in use before replacement. The existing EEPROM is not changed, and is connected to the new control PCB.

Before start-up

• Turn the system master switch to "ON".
• Turn the cut-off switch on the unit to the I-ON position.
• Check that the display of the controller indicates OFF, otherwise press the × key for 3 seconds.

In versions 15 and 18 three-phase, if alarm P05 appears on the control panel of the external unit, two phases of the power supply must be inverted.

The prompt SETTING will appear and flash on the control panel of the external unit. This signal will cease within a maximum time of 4-5 minutes once the panel has correctly communicated with the external unit.

If during the SETTING procedure the symbol appears accompanied by the prompt R.C.1., open the external unit inspection panel and press the AUTO ADD pushbutton (Automatic address button) on the electronic board (fig. 25).

External unit switch-on and control panel setting

A Anything to be done is the subject of this question.

Take the setpoint of the return water temperature to 45 so that it coincides with the one set on the user interface fitted on the control panel by pressing the key (fig.26 rif.3).

Controller switch-on and setting

To use the external unit modulation algorithm it is indispensable to set the setpoint ensuing that the one of the adjuster is always greater or equal to the one set on the external unit control panel.

• Select the summer or winter operation through the appropriate selector on the control panel.
• Press the × key on the user interface.
• Check that the display indicates the water temperature in the domestic boiler and that the LED of the operation selected (summer or winter) is switched on.

At this point, if the domestic boiler temperature is lower than the setpoint set (40^ factory set) the LEDs and switch-on and the external unit will start in heat pump mode after a time that will vary between 2 and 5 minutes (necessary for the device to perform the internal checks).

If, on the contrary, the domestic boiler setpoint is satisfied, the device will switch on in order to satisfy the request of the cooling or heating operation selected.

The programs exclude one another and the setting remains memorized even if the power supply is cut off.

Activation and deactivation

To perform the ACTIVATION and DEACTIVATION operations operate from the CONTROL PANEL.

If during this initial phase the signal "FL" should appear on the display, follow the instructions (see anomaly table on page 48):

• Check the water flow and the circulator unblocking.
  To access the control panel:
• Open the door (fig. 27 ref. A) simultaneously pressing with the thumbs on the knurled parts. At this point the door will open downwards.
  When the operations on the control panel are terminated:
• Close the door

Activation

• Select summer or winter operation through the appropriate selector on the control panel.
• Press the × key on the user interface.
• Check that the display indicates the domestic boiler water temperature and that the LED of the operation selected (summer or winter) switches on.

At this point, if the domestic boiler temperature is lower than the setpoint set (40^ factory set) the LEDs and switch-on and the external unit will start in heat pump mode after a time that varies between 2 and 5 minutes (necessary for the device to perform the internal checks).

If, on the contrary, the domestic boiler setpoint is satisfied, the device will switch on in order to satisfy the request of the cooling or heating operation selected.

The programs exclude one another and the setting remains memorized even if the power supply is cut off.

Activation et désactivation

• Press the × key on the user interface until oFF appears on the display
• Position the summer/stop/winter selector in the central position.

Checks during and after the first starting up.

When the start-up has been completed check that:

• The current absorbed by the compressor should be less than the maximum indicated in table 18 on page 26.
• Check that during the compressor operation the electrical power voltage corresponds to the nominal value +/- 10%.
• Check that the three-phase power supply has a maximum imbalance between phases of 3% .
• Check that the noise level three-phase compressor is normal, otherwise invert the two power-supply phases.
• The unit operates in the recommended operating conditions (see "technical data" chapter).
• All air has been completely bled from the hydraulic circuit
• The air-water heat pump performs a stop and then restarts.
• Always check the thermal difference between the system inlet and return - that must be between 4 - 7^
• checking parameters t1 and t3 with the i key (see paragraph 3.3.1).

If the thermal difference is less than 4^ set a lower speed for the circulator. If, on the contrary, the difference is greater than 7^ check that all of the valves of the system are open and possibly add an external pump in order to increase the flow rate of the water.

• Check the correct positioning of the inlet probe ensuring that the temperature indicated by the controller on the display is consistent with the temperature of the water at the inlet of the air-water heat pump.

LONG-TERM SHUTDOWN

When the air-water heat pump is not used for a long period of time, the following operations are to be performed:

• Press the ×少 key on the user interface until oFF appears on the display.
• Position the summer/stop/winter selector to the central position.
• Rotate the master switch of the device to the position 0-.OFF.

After having deactivated the unit:

• Deactivate the internal terminal units by turning the switch of each unit to "OFF"
• Turn the master switch to "OFF".
• Close the water taps.

Désactivation

If the outside temperature could fall below zero and there is a risk of freezing, the hydraulic system MUST BE EMPTIED, or else antifreeze must be added (e.g. ethylene glycol) in the dosage recommended by the producer of the liquid. The Customer technical service should be contacted.

To re-start the air-water heat pump after a long period of stop and inactivity, request an intervention of the Customer Technical Service.

When there is a boiler in the system, check that the circulating water temperature within the air-water heat pump does not exceed 65^ when it is operating.

CLEANING

The only cleaning operation required on behalf of the person responsible for the system is the external brushing of the air-water heat pump that is to be performed using only cloths dampened with water and soap. For persistent stains, use a solution of 50% methylated spirit in water or a specific product. When the cleaning is completed carefully dry the surfaces.

Do not use sponges with abrasive products or powder detergents.

All cleaning operations are forbidden until the unit has been disconnected from the mains power supply by turning the master switch on the system to OFF.

MAINTENANCE

Periodic maintenance is indispensable for maintaining the air-water heat pump always efficient, safe and reliable in time.

This can be carried out every six months, for some interventions and annually for others by the Customer technical service that is technically prepared and authorised and always has original spare parts available.

The annual maintenance programme that the OLIMPIA SPLENDID customer technical service or the authorised technician must perform envisages the following checks and operations:

• Check of the expansion tank pressure.
• Filling the water circuit.
• Air presence in water circuit.
• Efficiency of safety units.
• Power supply voltage.
• Electrical absorption.
• Tighten electrical connections.
• State of compressor contactor.
• Cleaning the fan grills and external unit battery fins.
• Check the metallic mesh filter for dirt.

OPERATING ASPECTS THAT SHOULD NOT BE INTERPRETED AS PROBLEMS

• The compressor does not start again until 3 minutes after being shut off.
• During operation in heating mode of systems with heat pump, heat is produced a few minutes after the compressor starts.
• Periodical defrosting cycles are performed during heating.

4.1 TABLE OF PROBLEMS AND SOLUTIONS
