• If the system has a leak-detection device installed, the checks for leaks must be performed at least every 12 months.
• When the unit is checked for leaks, keeping a record of all inspections is highly recommended.

- Before starting to operate on the appliance, it is necessary to check the zone surrounding the equipment to make sure there are no dangers of fire nor risks of combustion.

To repair the refrigerating system, it is necessary to take the following precautions before starting the intervention on the system.

THIS PRODUCT MUST BE USED EXCLUSIVELY ACCORDING TO THE SPECIFICATIONS INDICATED IN THIS MANUAL. USE DIFFERENT TO THAT SPECIFIED, COULD CAUSE SERIOUS INJURIES. THE MANUFACTURER IS NOT LIABLE FOR INJURY/ DAMAGE TO PERSONS/OBJECTS DERIVING FROM FAILURE TO COMPLY WITH THE REGULATIONS CONTAINED IN THIS MANUAL.

1. It is necessary to define the area around the work space and to avoid working in tight spaces. Ensure safe work conditions by checking flammable material.
2. All personnel in charge of maintenance and people which work in the surrounding area must be instructed on the type work they are going to carry out.
3. The zone MUST be checked with a specific refrigerating liquids detector before and during work, so that the technician is aware of potentially flammable atmospheres. Make sure the detection device of the leaks is suitable for use with flammable refrigerants,

EN - 8

then that it does not produce sparks and that is adequately sealed or intrinsically safe.

1. The leaks electronic detectors may need calibration. If necessary, calibrate them in a zone free of refrigerant.
2. Make sure the detector is not a potential source of combustion and that it is suitable for the refrigerant used. The device for detection must be set at a percentage of the refrigerant LFL and must be calibrated for the used refrigerant; the appropriate percentage of gas (maximum 25 %) must be confirmed.
3. If the presence of a leak is suspected, all open flames must be removed. If a fluid leak which requires brazing is encountered, all refrigerant must be collected from the system or insulated (by means of shut off valves) in a part of the system away from the leak. Then, bleed nitrogen without oxygen (OFN) through the system both before and after the brazing process.

1. In case it is necessary to carry out a hot work on the appliance, IT IS NECESSARY to have a powder or CO₂ fire extinguisher available.

1. To carry out a work which includes exposition of pipes which contain or contained a flammable refrigerant, DO NOT use sources of combustion. Risk of fire or explosion!

2. All sources of combustion (even a lit cigarette) should be kept away from the place in which all operations during which the flammable refrigerant may be released in the surrounding space must be carried out.

3. Make sure the area is adequately ventilated before intervening inside the system; a continuous degree of ventilation must be present.

1. DO NOT use means different from those recommended by the manufacturer in order to speed up the defrosting process or for cleaning.

2. Before any operation, always check that:

• the condensers are unloaded.
The operation must be carried out safely to avoid the risk of producing sparks;
- there are no live electrical components and that the cables are not exposed while loading, recovering or bleeding the system;

- there is continuity in the ground connection.

1. All electrical power supplies must be disconnected from the appliance on which you are working. If it is absolutely necessary that the appliance has electrical power supply, it is necessary to place a leak detector permanently operational in the most critical point.

1. Make sure the seals and sealing materials have not deteriorated. sible development of flammable atmospheres.

1. Do not apply any net inductive or capacity load to the circuit without making sure that this operation won't make you exceed the voltage and current permitted for the appliance in use.

The appliance for the test must have correct nominal values.

1. Periodically check that the cables are not subject to wear, corrosion, excessive pressure, vibrations, sharp edges or any other hostile environmental situation.

2. When intervening inside the refrigerating circuit to carry out repairs or for any other reason, the conventional procedures must be followed:

3. remove the refrigerant;

4. bleed the circuit with an inert gas;
5. evacuate;
6. bleed again with an inert gas;

7. open the circuit by cutting or by means of brazing.

8. The load of refrigerant must be stored in the specific custody cylinders.

The system must “cleaned” with OFN to make the unit safe.

It may be necessary to repeat this process several times.

DO NOT use compressed air or oxygen for this operation.

1. The cylinders must be kept in vertical position.

Only use cylinders suitable for collection of refrigerants.

The cylinders must be complete of a pressure-relief valve and switch off valves in good conditions.

A set of calibrated weighing scales must also be available.

1. The pipes must be equipped with couplings for disconnection and must NOT present leaks.

Before using the collection machine, check that it underwent correct maintenance and that the possible associated electric components are sealed, to prevent switching on in case of leak of refrigerant.

1. Make sure the refrigerating system is earthed before proceeding with reloading of the system with refrigerant. Label the system when

reloading is complete. Pay particular attention not to overload the refrigerating system.

1. Before proceeding with reloading, the system must undergo the pressure test with OFN and the tightness test at the end of reloading, but before commissioning.

It is necessary to carry out an additional tightness test before leaving the site.

1. Collected refrigerant must be returned to the fluid supplier in the appropriate collection cylinder, compiling the corresponding Transfer Note of Scraps.
   DO NOT mix the refrigerants in the collection units and, in particular, in the cylinders.
2. If the compressors or their oils must be removed, make sure they have been emptied at an acceptable level to be sure that the flammable refrigerant does not remain in the lubricant.
   This process must be carried out before the compressor returns to the suppliers.
   Only use electric heating on the compressor body to speed up this process.
3. Do not drill nor burn the unit.
4. The replaced electric components MUST be suitable and correspond to the appliance specifications. Every maintenance operation MUST be carried out as described in this manual. Contact the manufacturer in case of doubt.
5. Apply the following checks:

- The markings on the machine must always be visible and readable, correct them if not;

- The pipelines are the components containing refrigerant MUST be installed in a place where no substance may corrode them, unless the components are built with materials intrinsically resistant against corrosion or are suitably protected against this risk.

1. All the refrigerant must be recovered safely, also collect a sample of oil and refrigerant if it is necessary to collect a sample of oil and refrigerant in case an analysis is necessary before the reuse of the recovered refrigerant. Before carrying out the procedure, electrically insulate the system and make sure that:

2. the mechanical movement equipment of the cylinders containing refrigerant are available;

3. all the personal protective equipment is used correctly;
4. the recovery process is supervised, at any moment, by a compe-

EN - 11

tent person;

- the equipment and recovery cylinders are compliant with the standards.

Empty the system and, if that is not possible, use a collector in order to be able to remove the refrigerant. Before the recovery starts, make sure the cylinder is positioned on the scale and start the recovery machine working according to the instructions.

1. DO NOT fill the cylinders excessively (the liquid must not be higher than 80% of the volume). DO NOT exceed, even temporarily, the maximum operating pressure of the cylinder. Once the process is complete, as previously described, make sure the equipment and the cylinders are removed. Before switching on the appliance, check that all the insulation valves are closed.
2. Recovered refrigerant must not be discharged in another refrigerating systems unless it has been cleaned and checked.
3. Once installation is complete, check that there's no loss of refrigerant (the refrigerating liquid produces toxic gas if exposed to a flame).

0.5 - PROPER USE

• The air-conditioner should be used for the exclusive purpose of producing hot or cool air (on demand) for the sole purpose of obtaining a comfortable temperature in the room.
• An improper use of the devices (external and internal) with possible damages caused to people, things or animals relieves OLIMPIA SPLENDID from any liability.

0.6 - HAZARDOUS ZONES

- The climate controllers must not be installed in environments with the presence of inflammable gases, explosive gases, in very humid environments (laundries, greenhouses, etc.), or in places with other machines that generate a strong heat source, in proximity of a sources of salt water or sulphurous water.

- DO NOT use gas, gasoline or other inflammable liquids near to the climate controller.

- The climate controller does not have a fan for the introduction of fresh outdoor air into the room; ventilate by opening doors and windows.

• Always install circuit breaker and a dedicated power circuit.

A failure to implement the indicated standards, which may cause a malfunction of the appliances, relieves OLIMPIA SPLENDID from any form of warranty and from any liability for possible damages caused to people, animals or things.

The electrical system must be compliant with legal standards, must respect the data in the technical data sheet and be must be equipped with an efficient ground system.

2.2 - SIZE AND SPECIFICATIONS OF THE ROOM IN WHICH TO INSTALL THE AIR CONDITIONER

• Before installing the air conditioner, it is essential to make an accurate calculation of the heat load in summer (and cold load in winter for models with heating pump) at the site of installation.
• The more accurate this calculation is made the better the air conditioner will be able to do its job.
• When executing the calculations, refer directly to the prevailing standards.
• For particularly important applications, we recommend contacting expert heating engineers.
• The user should try to limit high heat loads as much as possible as follows: glass doors and windows exposed to many hours of sunlight should be fitted on the inside with curtains or, even better, on the outside with coverings such as Venetian blinds, verandahs, refractive film, etc.). The air-conditioned room must remain closed as long as possible.
• Halogen spotlights or other electrical equipment with high power consumption should not be used in the room (toasters, steam irons, hot plates for cooking, etc.).

2.3 - CHOOSING THE POSITION OF THE UNIT

To obtain the best operating performance and prevent faults or hazardous conditions, the position of indoor unit installation must meet the following requirements:

a. Do not expose the appliance to heat or steam sources (fig. 3).

EN - 15

b. Make sure that the space to the right and left is at least 100 mm and space above the unit is at least 80 mm. (fig. 2).
c. The wall where the indoor unit is to be fixed, must be stable, strong and suitable to support the weight.
d. It must be possible to leave room around the unit for any maintenance operations that may be necessary.
e. Nothing should be in the way of the air that needs to circulate both on the top air-intake (curtains, plants, furniture) and at the front where the air exits. This could cause air swirls that would inhibit the working efficiency of the unit (fig. 3).
f. Do not spray water or other liquids of any kind directly on the unit (fig. 3).
g. The appliance must not be positioned so that the air flow is directed directly towards nearby people (fig. 3).

3.3 - USE OF THE REMOTE CONTROL

The remote control supplied with the air-conditioner is the instrument that enables you to use the appliance in the most convenient way.

It should be handled with care and in particular:

• Keep it dry (do not clean it with water or leave it outdoors in bad weather).
• Avoid dropping or bumping it.
• Keep it out of direct sunlight.

The remote control only works with models with aesthetic panels Unico Vertical (UNICO VERTICAL 35HP EVAN-EVANX). For recess models (UNICO VERTICAL-NK 35HP EVAN-EVANX), the unit control occurs by means of the thermostats (available as optional kits).

- The remote control operates by means of an infrared beam.

• During use, there must not be any obstacle between the remote control and the air-conditioner.
• If other appliances in the room have remote controls (TV, stereo, etc...), there may be interference with consequent loss of the sent signal.
• Electronic and fluorescent lights may also interfere with transmissions between remote control and air-conditioner.
• Remove the batteries in case of prolonged disuse of the remote control.
• The remote control display goes off after a few seconds of non-use, to reactivate it press any key.

3.3.1 - Insertion of batteries (fig. 6)

To insert the batteries correctly:

a. Remove the batteries compartment cover.
b. Insert the batteries into the relevant compartment.

Check the polarity indicated on the bottom of the compartment.

c. Close the compartment correctly.

EN - 26

3.3.2 - Replacement of batteries

The batteries should be replaced when the display on the remote control does not appear sharply or when the remote control does not change the settings.

Always use new batteries and replace both at the same time. The use of old or different batteries could generate malfunctioning of the remote control.

The remote control uses two dry alkaline 1.5V batteries (AAA.LR03) (fig. 6).

When the batteries have been replaced, adjust the remote control clock.

When replacing batteries, replace both and dispose of the dead batteries in the appropriate collection centres and as required by law.

• If the remote control is not used for several weeks or longer, remove the batteries. Any leaks from the batteries could damage the remote control.
• The average life-span of the batteries, with normal use, is approx. six months. Replace the batteries when the indoor unit command receipt "beep" can no longer be heard, or if the transmission indicator on the remote control does not switch on.

Do not re-charge or disassemble the batteries. Do not throw the batteries into the fire. They can burn and explode.

If the battery liquid falls onto the skin or clothes, wash well with clean water. Do not use the remote control with batteries that have leaked. The chemical products contained in the batteries can cause burns or other risks to health.

3.3.3 - Location of the remote controller

- Keep the remote control in a position from which the signal can reach the appliance receiver (maximum distance is about 8 meters - with charged batteries) (fig. 7).

The presence of obstacles (furniture, curtains, walls, etc.) between the remote control and the appliance reduces the remote control range.

3.5 - DESCRIPTION OF THE AIR CONDITIONER FUNCTIONS

3.5.1 - Main switch-on and running management

- The machine may be regulated using the remote control.

In order to transmit commands to the indoor appliance, point the front of the remote control toward the appliance's control panel.

The device emits a beep when it receives a command.

- The maximum distance from which the appliance can be controlled is about 8 meters (with charged batteries).

3.5.2 - ECO key

- Pressing the B2 key on the remote control activates the energy saving function, automatically optimizing the machine functions, the D11 symbol appears on the display.

3.5.3 - Turning the unit ON/OFF

- Press key B1 on the remote control to activate or deactivate (stand-by) the air conditioner.

The control system of the unit is equipped with memory, for this reason all the settings won't be lost when shutting off the appliance itself.

In case of prolonged stop of the machine, it must be deactivated turning the main switch off or unplugging the machine from the mains.

3.5.4 - Operation in "Cooling" mode only

• When used in this mode, the air conditioner dehumidifies and cools the room.
• To activate this mode, press the key B4 on the remote control several times until

EN - 29

the D3 symbol appears on the display.

- In this run mode, the required temperature and fan speed can be set.

After three minutes (as a maximum) from activation in this operating mode the compressor will start and the appliance starts emitting cold air.

3.5.5 - Operation in "Dehumidification" mode only

• When used in this mode, the air conditioner eliminates the humidity in the room.
  This function can be extremely useful between seasons, particularly on rainy days when the temperature is not uncomfortable but the excess humidity feels unpleasant.
• In this mode, both room temperature and fan speed settings are ignored, which correspond to minimum.
• Then, any indication of temperature and speed of the fan disappears from the display of the remote controller and from the control panel.
• To activate this mode, press the B4 key on the remote control several times until the D4 symbol and the D1 (fan plus first notch) automatic ventilation symbol appear on the display.
• In this operating mode it is normal for the air conditioner to function intermittently.

3.5.6 - Operation in "Ventilation" mode only

• When used in this mode the air conditioner does not perform any action with regard to temperature and air humidity in the room.
• To activate this mode, press key B4 on the remote control several times until the automatic ventilation symbol D1 (fan plus first notch) appears on the remote control display.

3.5.7 - Operation in "Comfort" mode only (Automatic)

• In this mode, the machine's temperature is automatically regulated according to the room's temperature. The fan speed is also automatically regulated according to the set temperature (except in dehumidification mode).
• To activate this mode, press the B4 key on the remote control several times until the D7 symbol appears on the display.

3.5.8 - Operation in "Heating" mode only

• Using this mode, the appliance heats the room.
This function is only available for the versions with heat pump (HP).
- To activate this mode, press button B4 on the remote control several times until the D2 symbol appears on the display.
- In this run mode, the required temperature and fan speed can be set. After three

minutes (maximum time) the compressor should start and the air conditioner starts heating the room.

The air conditioner has to defrost its battery periodically.

During this operation the air conditioner does not heat the room, though its internal parts remain on except for the room air fan. when the outdoor temperature is very low, there may be a slight delay for passage from the minimum to the medium or maximum speed from when the command is sent to the machine with the remote control.

After having turned off the unit, the internal fan runs seconds more. Then it stops.

If the unit is equipped with a electric heater, it activates automatically as a back up source of heat to the compressor, when operating in low ambient external temperatures.

The switch temperature in electric back up heat is 4^ C outdoor as facotry default; the value can be modified within the range of -15^ C and 13^ C by an authorised TAC. When the electric heater is working a orange indication (LED3) is lighted on the control panel.

• The fan speed check occurs through key B5 (on the remote control).
• Pressing several times this key will cause speed to change according to the following sequence:

$$ \text { Low } > \text { Medium } > \text { High } > \text { Automatic }. $$

• The higher the speed setting, the greater the output of the air conditioner but also the louder its operation.
• By setting the Automatic mode, the onboard microprocessor adjusts the automatic speed. The higher the difference between the room temperature detected and the temperature set, the higher the speed.
• As the room temperature nears the setting, fan speed is reduced automatically.
• In dehumidification mode, it is not possible to control the speed as the appliance can only operate exclusively at low speed.

3.5.10-SILENT key

• To activate this mode, press the B3 key on the remote control, the D6 symbol appears on the display.

• Activating the SILENT allows you to obtain multiple results:

• gradual increase in the set temperature during cooling mode

• gradual decrease in the set temperature for heating (HP versions only)
• reduction of the sound level of the appliance
• decrease of the fan speeds

- For activation of the SILENT function, it is first necessary to select the operating mode and the desired temperature, then activate the SILENT function by pressing the key B3.

- Noise reduction entails an optimization of noise and thermal/cooling capacity of the machine. In the event that, in some moments, the thermal/cooling power is insufficient, deactivate the SILENT function.

3.5.11 - Timer setting

• The appliance logic allows the User to make use of two different timer programs (see paragraph 3.5.14), thanks to which the appliance can be deactivated and activated (or vice versa) whenever desired (for example, it can be activated shortly before returning home so as to find an already pleasant temperature in the room).
• Firstly, if it is desired to make use of these functions, set the correct time (see paragraph 3.5.13) and then set the timer as you prefer.

Do not touch the metal parts of the unit when removing the air filters. They are very sharp. Cuts or injury risk.

5.1 - CLEANING

5.1.1 - Appliance and remote control cleaning

Use a dry cloth to clean the appliance and the remote control (fig. 38).

It is possible to use a cloth moistened with cold water to clean the appliance if it is very dirty.

Suck between the air inlet and outlet grilles (fig. 38).

Do not use a chemically treated or antistatic cloth to clean the appliance. Do not use gasoline, solvent, polish or similar solvents.

These products could cause the breakage or deformation of the plastic surface.

5.1.2 - Cleaning the air filter

To ensure an efficient filtration of the internal air and a good operation of the air conditioner and good operation of the air conditioner, it is essential to periodically clean the air filter. The air filter is at the top of the unit.

a. Switch off the unit.
b. Electrically disconnect the appliance.
c. Raise the frontal (F1), if applicable, and sides (F2) filters from the frontal grid (fig.12).
d. Wash and dry the filter thoroughly.

e. Reassemble the frontal (F1), if applicable, and sides (F2) filters For UNICO VERTICAL-NK 35HP EVAN-EVANX unit insert the rear edge of the filter inside the grille (fig. 12).

To cancel the dirty filter report, after having connected the air conditioner to the mains voltage, press simultaneously, for at least 5 seconds, the keys Stand-by and MODE located on the command panel. This way, the dirty filter report is cancelled and the respective counting is reset.

Do not use the appliance without filter or if the latter is damaged.

5.2 - MAINTENANCE

If you plan to idle the unit for a long time, perform the following:

a. Stop the air conditioner and disconnect the power supply.
b. Remove the batteries from the remote control.

Do not perform them alone.

5.2.1 - Routine maintenance

The air conditioner that you have purchased has been designed to reduce routine maintenance operations to a minimum.

These operations involve solely the cleaning operations outlined below:

• Cleaning or washing of the ambient air filter every 2 weeks or every time the relative red LED lights up (this can be done by the user, see user manual).
• Inspect and clean the refrigerant coils and the condensate management system at least once per year.
• Maintenance should be performed by skilled technicians.

The installer should gather up all packing material and use a damp cloth to remove any traces of dust or dirt during assembly. It's also recommended to explain system operation to the end user, show them how to remove and clean the air filters then make them familiar with the installation and operating instructions.

5.2.2 - Condensation water drainage in case of emergency

In the event that anomalies should occur on the condensation water disposal system, the air conditioner stops and reports the alarm code 20 on the display of the front panel of the machine.

To make the appliance work temporarily while waiting for the arrival of the assistance centre, it is possible to drain the water inside through simple operations described below.

Before proceeding with any maintenance and cleaning, always make sure the system has been switched off, using the remote control, and the power supply plug has been disconnected from the system socket (or the upstream master isolating switch is positioned at "0" OFF).

• Pull the tube (1) slightly to extract it from the cable clamp (2) located under the machine base.
• Position a large container, turn the tube (1) and place it on top of the container.
• Remove the cap (3) and let the water drain out.
• Once the fault has been removed, the service centre will close the evacuation duct again.

5.3 - DIAGNOSIS, ALARMS AND INCONVENIENCES

5.3.1 - Diagnosis of the inconveniences

It is important for the User to distinguish between functional problems and anomalies in relation to the behaviour of the appliance as foreseen for its normal operation. Furthermore, the most common problems may easily be solved through simple operations on behalf of the User (See paragraph 5.3.4 - Anomalies and solutions).

For all the other reports (see paragraph: 5.3.3), it is necessary to always contact the technical assistance service"

Any attempt to repair the appliance by unauthorised personnel will immediately invalidate any form of guarantee.

5.3.2 - Functional aspects not to be mistaken for anomalies

The following events may occur during normal operation:

a. The compressor does not start up again immediately after a stop (it takes about three minutes to start again).

- In the operating logic of the appliance a delay between a compressor stop and its successive restart has been included, so that the compressor itself is protected against activations that are too frequent.

b. During the heating operation of the heat pump appliances, the flow of hot air may occur some minutes after activation of the compressor.

- Should the fan start at the same time as the compressor, for the first few minutes it would emit cold air into the room (and this could bother the occupants) since the unit has not yet reached steady running conditions.

c. Should a blackout occur, alarm code 08 or 50 will appear.

5.3.3 - Console alarms

If one of the alarms persists for more than three minutes, contact an Olimpia service centre.
