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.

1. 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.

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

EN-8

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.
   5a. Fluids for the detection of losses are suitable for most part of the refrigerants. Detergents containing chlorine MUST be avoided.
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 CO, fire extinguisher available.

2. 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!

3. 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.

4. 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:

3. the condensers are unloaded.

EN-9

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. ible development of flammable atmospheres.
2. 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.

15a. The only components on which you can operate in flammable atmosphere are those intrinsically safe.

The test device must be set with the correct conditions. The components must be replaced ONLY with parts of the manufacturer. Danger of loss of refrigerant in the atmosphere, risk of explosion.

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.

18a. Make sure that, while recharging the system THERE IS no contamination of the various elements. The pipes or conducts MUST be as short as possible to minimize the content of refrigerant inside them.

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.

22a. Remove the refrigerant safely. Move the refrigerant in the cylinders suitable for recovery. Make sure there is a correct number of cylinders to contain the charge entirely. All cylinders are labelled for this type of refrigerant (special cylinders for refrigerant recovery). The cylinders must be complete of a pressure relief valve and of and of the corresponding closure valve in good conditions. Empty cylinders are evacuated and, if possible, cooled down before recovery.

22b. Equipment for recovery must be within the range of the technician, in good conditions, with a series of instructions and must be suitable for recovery of all the refrigerants (even flammable ones). A series of calibrates scales must be available and in good conditions. Check that the pipes are in good conditions and complete of disconnection joints without losses.

22c. Before using the machine for recovery, check that it is in good operating conditions, that it has been adequately maintained and that all the associated electric components are sealed to prevent switching-in in case of release of refrigerant. In case of doubt, please contact the manufacturer.

1. Collected refrigerant must be returned to the fluid supplier in the appropriate collection cylinder, compiling the corresponding Transfer Note of Scaps.

DO NOT mix the refrigerants in the collection units and, in particular, in the cylinders.

EN-11

1. 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.

1. Do not drill nor burn the unit.
2. 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.

3. Apply the following checks:

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

5. The pipelines ore 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.

6. 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:

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

8. all the personal protective equipment is used correctly;
9. the recovery process is supervised, at any moment, by a competent person;
10. 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.

1. Recovered refrigerant must not be discharged in another refrigerating systems unless it has been cleaned and checked.
2. Once installation is complete, check that there's no loss of refrigerant (the refrigerating liquid produces toxic gas if exposed to a flame).
3. THE CHARGE OF R290 CONTAINED IN THE MACHINE IS 145g. For this reason, being lower than m1=152g, as defined by the standard IEC 60335-2-40:2022, the unit has no installation bonds linked to the area of installation.

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.

2 - INSTALLATION

2.1 - INSTRUCTIONS FOR INSTALLATION

To obtain the best results and optimum performance, follow the instructions for correct installation provided in this manual.

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.

EN-16

• 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).
b. Make sure that the space to the right and left is at least 60~mm and space above the unit is at least 80~mm . (fig. 2).
c. The height of the unit's lower edge from the floor should be at least 100mm if fixed to the wall in the lowest position. If fixed to the wall in the highest position, it should be at least 80mm from the ceiling (fig. 2).
d. The wall where the indoor unit is to be fixed, must be stable, strong and suitable to support the weight.
e. It must be possible to leave room around the unit for any maintenance operations that may be necessary.

EN-17

f. 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).
g. Do not spray water or other liquids of any kind directly on the unit (fig. 3).
h. The appliance must not be positioned so that the air flow is directed directly towards nearby people (fig. 3).
i. Never force the opening of the airflow flap (fig. 3).
I. Do not place bottles, cans, clothes, flowers or any other object on the air suction grille (fig. 3).
m. Do not install the air conditioner directly on another household appliance (TV, radio, fridge, etc.), or on a heat source (fig. 3).

3

EN-18

The air conditioner must be installed on a wall that communicates with the outside

After determining the best place for installation as described above, check for the absence of other structures or systems (beams, piers, pipes, wires, etc.) at the points where the holes are to be drilled, which would prevent drilling the holes required to install the unit.

Check again to make sure there are no obstacles to air circulation through the holes to be drilled due to plants and their leaves, slats or panelling, blinds, gratings or grids too dense, etc.).

2.4 - UNIT ASSEMBLY

The maximum length allowed for the pipes is 1m , the pipes must be internally smooth and no bends can be made.

It is necessary to use the grilles provided, or grilles which keep the same features.

2.4.1 - Drilling the wall

To operate, the unit requires two holes to be drilled in the wall, positioned as indicated on the drilling template; the holes can have both a 162mm and 202mm diameter.

• It is possible to install the unit UNICO NEXT-F instead of a unit UNICO SKY, UNICO STAR, UNICO SMART or UNICO INVERTER without modifying the already existing holes, exception made for the small condensation drain hole.

In this case, in order not to penalize performances, remove the insulating material possibly present in the air expulsion hole. The anchoring brackets need new drilling too.

• Drill the wall using the proper tools to facilitate your job and prevent excess damage or disturbance to your client.

The best tools for drilling large holes in walls are special drills called core borers with very high twisting torque and adjustable rotating speed depending on the diameter of the hole to be drilled.

• To prevent the creation of large amounts of dust and rubble due to drilling, the core borer can be fitted with a vacuum system applied by means of suction cups to the drilling zone.

• To drill the holes, proceed as follows:

• Place the supplied drill jig (M) against the wall observing the minimum distances from the ceiling, the floor and from the side walls indicated on the jig itself which can be kept in the correct position using adhesive tape (Y) (fig. 4).

• Use a small drill or punch to mark, with extreme care, the exact centre of each of the holes to be drilled (fig.4).
• Using a core boring head measuring at least 202mm (or 162mm ) to drill the two holes for entry and exit of the air.

Drill the foregoing holes tilted slightly downwards to prevent water from being fed back through the ducts (fig. 5).

Most of the removed material is expelled outwards, therefore make sure that it does not hit any person or object when it falls out.

In order to avoid as much as possible outer plaster breaking, it is necessary to proceed carefully with the last part of hole execution, decreasing pressure on core borers.

• Drill the holes, previously marked, for the wall plugs related to the fixing brackets (fig. 6).

EN-20

Carefully check the characteristics and consistency of the wall in order to possibly choose wall plugs specific for particular situations.

The manufacturer will not be held liable for any underestimates made in the structural consistency of the anchor prepared by the installer. Therefore, pay utmost attention to the foregoing operation that could cause serious injury/damage to people/property if carried out incorrectly.

• For all the appliances, an in-wall condensation drain must be installed (see paragraph 2.4.2), in order to drain the condensate it will be necessary to drill a hole through the wall in the position shown on the template.

2.4.2 - Preparing the condensate discharge

• It is necessary to connect the condensation drainage tube (N), to be inserted into the specific coupling (X) located on the back of the unit, to the air conditioner.

Remove the cap (B) (fig. 7) before inserting the condensation drain pipe.

• Since condensate drains by gravity, there must be a minimum slope of at least 3% at every point of the discharge line.

Use a rigid or flexible tube having an inside diameter of at least 16mm

• If the line empties into a sewerage system, install a siphon before the point in which the pipe reaches the main discharge, at least 300mm below the inlet from the unit (fig. 8).

The condensation drain is mandatory as the unit is not equipped with an internal pump for disposal of condensation.

• If the drainpipe drains into a vessel (tank or other container), this container should not be sealed and the drainpipe should not remain immersed in the water (see fig. 9).
• The hole (J) through which the condensate pipe passes should always slope towards the outside (see fig. 10).

The exact position in which to place the pipe inlet, as compared to the machine is shown on the drilling template.

Make sure, in this case, that the water expelled outward does not damage or disturb persons or property.

During the winter this type of drainage may cause sheets of ice to form.

When the condensate drainage is fitted, pay much attention not to compress the rubber hose.

In the event of operation during the winter with temperatures equal to or lower than 0^ C, make sure that the condensate drain pipe is protected from freezing in order to ensure draining.

In the event of prolonged operation during the winter with temperatures below 5^ , install the optional basin heater kit.

2.4.3 -Assembly of the air ducts and external grids

• After drilling the holes (with the core drill), insert the plastic sheet (H) supplied with the air conditioner (fig. 11) inside them.

Since the sheet (H) was made for 202mm holes, you will have to cut off 130 mm from the long side of the sheet for the 162mm holes (fig. 11).

The sheets must be 65mm shorter than the length of the wall.

EN-22

• Roll the sheet (H) and insert it into the hole, paying attention to the splicing line, which must always face upwards. (fig.11).

Use an ordinary cutter for the foregoing operation (fig. 11 - 12).

To position the external grids, proceed as follows:

a. Apply the seal (G) to the wall flange (D), ensuring it lines up with the outer edge of the flange as indicated in the figure 13.

3 - USE

3.1 - WARNINGS

The installation and electrical connection of the air conditioner should be carried out by specialized personnel who possess the requisites set forth by law.

The installation instructions are contained in the appropriate paragraph of this manual.

No structural object (furniture, curtains, plants, leaves, blinds, etc.) should ever obstruct the normal flow of air from either the internal or external gratings.

• Never lean or, worse yet, sit on the casing of the air conditioner as this could cause serious damage to the external parts.

• Do not move the air outlet flap by hand. Always use the remote control to adjust baffle position.

• If the unit leaks water, switch it off immediately and disconnect it from the power mains. Call the nearest service centre.
• When the air conditioner is heating, it has to periodically eliminate any ice that could form on the external battery. While it is doing this, the machine keeps running but does not heat the room. This lasts for a brief period of time, from 3 to a maximum of 10 minutes.
• Clean the air filter periodically, as described in the specific paragraph (5.1.2).

The air conditioner must not be installed in rooms where explosive gasses develop or where there are conditions of heat and humidity beyond the maximum limits indicated in the installation manual.

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 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. 31)

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.

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. 31). 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.

EN-34

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

3.4 - DESCRIPTION OF REMOTE CONTROL

The remote control is the interface between the air-conditioner and the customer, so it is very important to learn all its functions, the use of the various controls and the meaning of the symbols marked on it.

3.4.1 -Description of the remote control keys (Fig. 33)

EN-35

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 - 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.

3.5.3 - Operation in "Cooling" mode only

• When used in this mode, the air conditioner dehumidifies and cools the room.
• To activate this mode, press the B4 key on the remote control several times until the LED 1 lights up blue and the display shows the set temperature.
• 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.

3.5.4 - 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 LED 1 lights up blue.
• In this operating mode it is normal for the air conditioner to function intermittently.

3.5.5 - 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 the B4 key on the remote control several times until the display shows one of the three settable speeds (HI, ME, LO).

3.5.6 - 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 display shows the symbol “R”.

3.5.7 - 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 the B4 key on the remote control several times until the LED 1 lights up red and the display shows the set temperature.
• 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.

Like delays might occur on activating the swinging function of the mobile baffle.

After having turned off the unit, the internal fan runs seconds more. Then it stops and both air flaps close.

3.5.8 - Checking airflow direction

• Press key B8 on the remote control to activate/deactivate the continuous oscillation of the moving air outlet deflector (1).

EN-37

• When continuous oscillation is active, an additional press of the key B8 allows to lock the deflector so as to obtain the desired vertical direction for the air flow.

The moving deflector position must never be forced manually.

• The fan speed check occurs by means of the keys B2 (increase) - B3 (decrease).
• 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 - Reset of all the remote controller functions

By replacing the batteries or removing them even for a few moments, all the settings of the remote controller are reset. Doing this cancels all the time settings of the timer save in the remote controller and the remote controller restores all the factory settings.

3.5.11 - Managing the unit if the remote control is not available

In case of loss or malfunctioning of the remote controller or death of the batteries the air conditioner can be controlled by the keys on board of the machine.

3.6 - RECOMMENDATIONS FOR ENERGY SAVINGS

Below find simple recommendations for reducing consumption:

• Always and constantly keep the filters clean (see maintenance and cleaning chapter).
• Keep the doors and windows of the rooms to be climate controlled closed.
• Avoid the sun's rays penetrating freely into the room (we recommend using curtains or lowering blinds or closing the shutters).
• Do not obstruct the unit air flow (inlet and outlet), i.e. in addition to bad performance of the system, it also affects correct operation and the possibility of irreparable faults to the units.

4 - FUNCTIONS AND ACCESSORIES

4.1 - MODBUS RTU RS485

The communication port allows the air conditioner to carry out the following functions:

• Send the commands to the air conditioner, exactly as the remote controller.
• Send another temperature of the room to the air conditioner, read by a wall thermostat.
• Read the work status of the air conditioner and configure it.
• Debug the behaviour of the machine.
• Manually command the fan and all the loads of the machine.

Instead of using the connector, it is possible to use the black (signal A) and green (signal B) cables directly.

EN-40

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).
• Cleaning of the condensing battery and cleaning of the condensate management system.

These operations must be carried out by skilled technicians on a regular basis that will depend on the place of installation and intensity of use.

Depending on the quantity of dirt, the unit can be cleaned dry (by using a battery compressor and bowl and cleaning the fins with a soft brush taking care not to deform them) or more thoroughly using dedicated detergents.

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).

EN-41

Open the door (5) underneath the unit.

a. Remove the cap (6a) after having placed a good-sized container underneath it (at least 5-liter capacity) to collect the water (fig. 43).
b. After having cleared the fault, the service personnel will close the evacuation pipe.

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.

EN-42
