• This climate control appliance contains uorinated gas. For specic information regarding the type and quantity of gas, refer to the data plate a󰀩xed to the unit.

• The installation, assistance, maintenance and repair of the appliance, must be performed by a qualied certied technician.

• Product removal and re-cycling operations must be performed by a qualied certied technician.

• 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 re nor risks of combustion. To repair the refrigerating system, it is necessary to take the following precautions before starting the intervention on the system.

1. The zone MUST be checked with a specic refrigerating liquids detector before and

during work, so that the technician is aware of potentially ammable atmospheres. Make sure the detection device of the leaks is suitable for use with ammable refrigerants, then that it does not produce sparks and that is adequately sealed or intrinsically safe.

2. The leakage electronic detectors may need calibration.

If necessary, calibrate them in a zone free of refrigerant.

3. 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 conrmed. 3a. The leakage detection uids are suitable for most of the refrigerants. The detergents containing chlorine MUST be avoided. Danger of corrosion of the copper pipes.

4. If the presence of a leak is suspected, all open ames must be removed.

5. All sources of combustion (even a lit cigarette) should be kept away from the place

in which all operations during which the ammable refrigerant may be released in the surrounding space must be carried out.ENGLISH EN - 6

6. Make sure the area is adequately ventilated before intervening inside the system; a

continuous degree of ventilation must be present.

7. 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.

8. Periodically check that the cables are not subject to wear, corrosion, excessive

pressure, vibrations, sharp edges or any other hostile environmental situation.

9. When intervening inside the refrigerating circuit to carry out repairs or for any other

reason, the conventional procedures must be followed:

• remove the refrigerant;

• bleed the circuit with an inert gas;

• bleed again with an inert gas;

• open the circuit by cutting or by means of brazing. 9a. Oxygen-Free Nitrogen (OFN) MUST be purged through the system both before and during the brazing process. 9b. When the nal OFN charge is used, the system must be discharged up to atmospheric pressure to allow the execution of the work. This operation is absolutely essential if it is desired to carry out brazing operations on the pipes.

10. The load of refrigerant must be stored in the specic 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. 10a. Make sure that contamination between di󰀨erent refrigerants does NOT occur when a reloading equipment is used. The exible pipes or ducts MUST be as short as possible to reduce the quantity of refrigerant inside them to a minimum.

11. 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 o󰀨 valves in good conditions. A set of calibrated weighing scales must also be available.

12. 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.

13. 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.

14. 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. 14a. 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. 14b.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 ammable 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. 14c. 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,NEXYA S5 E ENGLISH EN - 7 please contact the manufacturer.

15. Collected refrigerant must be returned to the uid supplier in the appropriate

collection cylinder, compiling the corresponding Handover Note of Scraps. DO NOT mix the refrigerants in the collection units and, in particular, in the cylinders.

16. Make sure that contamination between di󰀨erent refrigerants does not occur when

a reloading equipment is used. The exible pipes or ducts must be as short as possible to reduce the quantity of refrigerant inside them to a minimum.

17. Do not drill nor burn the unit.

18. The replaced electric components MUST be suitable and correspond to the appliance

specications. Every maintenance operation MUST be carried out as described in this manual. Contact the manufacturer in case of doubt.

• The ventilation device works correctly and the outlets are not clogged;

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

• 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.

20. The refrigerating gases are odourless.

21. For disposal and marking (through signs) of the appliance containing refrigerant

gas, please refer to the local regulations.

22. To store the appliance: The packaging for storage must be resistant in order to

avoid that the appliance may take damage and to avoid the possible leakage of refrigerant gas.

23. Recovered refrigerant must not be discharged in another refrigerating system

unless it has been cleaned and checked.

24. Dismantling MUST be carried out by a qualied technician whom MUST use the PPE

correctly and MUST perfectly know the equipment. All the refrigerants MUST be recovered safely; always collect a sample of oil and refrigerant before emptying the circuit.

25. Before starting any dismantling operation:

- Electrically insulate the system. - Ensure that you have mechanical handling equipment at your disposal to handle the tanks, if necessary. - The equipment and recovery tanks MUST be in compliance with the standards.

26. The equipment must be labelled indicating that it has been deactivated and emptied

of refrigerant. The label must be dated and signed. Make sure that on the equipment are present labels indicating that the equipment contains ammable refrigerant.

27. If the compressors or compressor oils must be removed, it is necessary to check

that they have been extracted safely and at an acceptable level to ensure that the ammable refrigerant has not remained inside the lubricant. The evacuation process must be carried out before returning the compressor to the suppliers. To speed up this process, only electric heating of the compressor body must be used.

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.

0.6 - CHECKS TO PERFORM BEFORE INSTALLATION

a. Checks at the area Before starting to work on the systems containing inammable refrigerants, safety checks are necessary to reduce the risk of ignition to a minimum. To repair a refrigeration system, the following precautions must be complied with before working on the system. b. Work procedure The job must be performed according to a controlled procedure in a way to reduce the risk of the presence of inammable gas or vapour to a minimum during the performance of the job. c. General work area All maintenance personnel and those working in the local area, must be trained regarding the job performed. Do not work in tight spaces. The area around the work area must be isolated. Guarantee that the conditions inside the area are safe by verifying the inammable material. d. Check the presence of refrigerant The area must be checked using a specic refrigerant detector before, during and after the execution of the work so as to ensure that the technician is informed about the presence of possibly ammable atmospheres. Check the leak detector equipment used is suitable for use with inammable refrigerants, i.e. does not cause sparks, is suitably sealed or intrinsically safe. e. Presence of extinguishers Whenever work must be performed on the refrigeration system at high temperatures or on relative components, a suitable re-prevention system must be prepared. Position CO2 or dry powder extinguishers in proximity of the loading area. f. No source of ignition No-one working in the refrigeration systems and exposed to contact with the piping that contains or contained inammable refrigerant, must use sources of ignition in order to prevent the riskNEXYA S5 E ENGLISH EN - 9 of re or explosion. Every possible source of ignition, among which cigarette smoke, must be kept at a due distance from the place of installation, repair, removal or disposal, where there is a risk of the refrigerant liquid leaking into the surrounding space. Before performing the job, the area surrounding the appliance must be controlled in order to ascertain that there are no inammable substances or risks of ignition present. NO SMOKING signs must be displayed. g. Ventilated area Make sure that the area is open or suitably ventilated before interacting with the system or performing any operation at high temperatures. Ensure constant ventilation during the operations period. Ventilation must safely disperse all refrigerant released and, if possible, expel it outside into the atmosphere. h. Refrigeration system checks If modied, the electric components must be suitable for the purpose and compliant with the correct specications. Always follow the manufacturer’s guide lines relative to maintenance and technical after-sales assistance. If in doubt, consult the manufacturer’s technical after-sales service. The plants that use inammable refrigerants must be subjected to the following verications:

• the dimension of the load must be compliant with the chamber in which the components containing the refrigerant are installed;

• the plants and ventilation outlets must operate adequately and not be obstructed;

• if an indirect refrigeration circuit is in use, check the presence of refrigerant in the secondary circuit; the marking on the systems must be visible and legible;

• illegible markings and signs must be corrected;

• the pipe or refrigeration components must be installed in a position where it is improbable that they are exposed to substances that could corrode the components containing the refrigerant, unless the components are manufactured with intrinsically corrosion resistant materials or are appropriately protected from corrosive agents.

i. Check the electric devices

The repair and maintenance interventions of electric components must envision initial safety checks and component inspection procedures. In the case of a fault which may compromise safety, no electric power supply must be connected to the circuit until it has been suitably repaired. If the fault cannot be repaired immediately, but the operation must be continued, use a suitable temporary solution. This solution must be communicated to the owner of the plant so that all parties can be informed. The initial safety controls envision:

• draining the condensers: this operation must be performed safely to prevent the possible formation of sparks;

• no exposure of components and electric wiring to voltages during loading, repair or purication of the system;

• the continuity of the earth. l. Repair interventions of the hermetic components

• During the repair of hermetic components, all electric power supply lines must be disconnected from the appliance running, before the eventual removal of the hermetic covers, etc. Whenever it is absolutely necessary to have electric power supply for the unit during maintenance, a constantly active leak detector must be positioned in the most critical point in order to signal a potentially dangerous situation.

• Particular attention must be paid to the following to guarantee that, in the case of intervention on electric components, the housing is not altered in a way to affect the level of protection.NL

2.7 - Selection of position of the inside 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 indoor unit to heat or steam. b. Make sure that the space to the right and left is at least 120 mm and space above the unit is at least 150 mm. (gure 1). c. The indoor unit must be installed at a minimum height of 2 metres and maximum of 3 metres from the oor. d. The wall where the indoor unit is to be xed, must be stable, strong and suitable to support the weight. e. There must be no obstacles for the free circulation of air both from the inlet side and especially the outlet side. In particular, there must be no obstacles within a distance of 2000 mm. A shorter distance could cause turbulence such to prevent correct operation of the appliance. f. If possible, install the unit on an outdoor wall, in a way to be able to convey condensate draining to the outside. g. The indoor unit must not be in a position such that the air ow is aimed directly at the persons below (gure 3). h. The indoor unit must not be installed directly above household appliances (television, radio, refrigerator, etc.) or above a heat source (gure 2).

i. Install the indoor unit in a way that there are no obstacles, which do not allow the signals emitted by the

remote control to be received (gure 4).

2.8 - INSTALLATION OF THE INSIDE UNIT

After checking what is described in the previous paragraph, proceed with the assembly of the xing plate (7) while taking into consideration the dimensions indicated in gure X1.a. Position the plate against the wall.b. Mark the drilling points, making sure that they are level.c. Make the holes necessary in the wall using a suitable bit. Make sure there are no pipes or electric ducts in the drilling area. d. Insert the plugs (4) into the holes and x the plate (7) to the wall using the screws (3) supplied (gure 5). Using a spirit level, make sure that the xing plate (7) is level. e. If the wall is in wood, use relevant countersunk-head screws (not supplied). f. Check the stability of the plate (7), moving it laterally and vertically.X1

If the connection lines arrive from the rear right of the indoor unit, a hole “R” must be made for passage of the piping, as successively described (see gure X1). a. Make a 6÷7 mm hole in the centre of the position “R”, with slope towards the outdoors of 5% (to allow condensate to be drained correctly (gure 6). b. Make the hole “R” using a core drill with the diameter indicated in the table of gure X1. c. Insert the drain line piping and that of refrigeration into the hole along with the electric connection cable. If the connection lines arrive from the rear left of the indoor unit, a hole “L” must be made for passage of the piping (see gure X1).

2.8.3 - Piping connection

a. Based on the position of the wall hole with respect to the mounting plate, choose the side from which it is wished the refrigerant pipes come out from the unit. b. If the wall hole is located at the side of the internal unit, remove the precut plastic panel from the unit side. It is possible to use pliers to ease the opening of the precut panel (g.7). The refrigerant pipes can come out from the internal unit with four different angles:

• Rear side to the left

• Rear side to the right Please refer to gure 7 for further details. c. Attach the upper bracket present in the rear part of the indoor unit to the upper hook of the xing bracket (pos. L - gure 8). d. Move the unit laterally to ensure it is correctly attached to the xing hook (7). e. If the connection pipes are already tted in the wall, directly proceed with the connection of the drain pipe. Piping connection is easily performed by lifting the indoor unit and introducing cladding between the same and the wall (pos. N - gure 8). Remove the cladding once connection has been completed. f. Push the lower part of the indoor unit towards the wall to attach it to the xing bracket (pos. M - gure 8). g. Try and move the indoor unit laterally and vertically to make sure that it is attached securely.NEXYA S5 E ENGLISH EN - 19

2.8.4 - Drain pipe connection (gure 9)

a. Insert the drain pipe (A), making sure that it slopes downwards. b. If necessary, connect an extension (C) to the drain pipe, isolate the joint with a protection pipe (B). Tightly wind the connection point with a Teon tape so as to ensure good tightness and im- pede possible leakage. The part of the drain pipe which remains inside shall be wrapped in a foam rubber sleeve to impede the formation of condensation. c. Remove the air lter and pour a small quantity of water inside the drain tray to check that water ows out correctly from the unit.

2.8.5 - Piping and protection wrapping connection (gure 10)

Evenly wrap the connection cable, drain pipe and electric cables with electrical tape, as illustrated in gure 10. Given that the condensate water from the rear of the indoor water is collected in the “Pond Box” tray and taken out of the compartment, do not put anything in the tray. Key (gure 10) A Collection tray B Piping compartment C Electrician’s tape D Connection pipe E Connection cable F Drain pipe

2.8.6 - Connection of the condensate drain line

Connect a drain pipe, of appropriate length, to the indoor unit condensate drain pipe, and block it with a strap. Make it run inside the duct parallel to the system pipes, fastening it to the same using straps. Do not tighten the straps excessively in order to prevent damage to the insulation of the pipes and narrow the drain pipe. Where possible, make the condensate liquid ow directly into a rainwater gutter. If the drain pipe is fed into a sewage system, it is necessary to bend the pipe in order to create a siphon (gure 11), in order to avoid the diffusion of unpleasant odours into the environment. The siphon bend must never be at a level below 1500 mm from the lower wire of the appli- ance (gure 11). If draining is into a recipient (gure 12), this must never be closed so as not to prevent counter-pressures such to compromise the operation, and the pipe itself must never reach the level of the liquid deposited.

2.9 - REFRIGERANT PIPING CONNECTION

When connecting refrigerant piping, do not let substances or gases other than the specied refrigerant enter the unit. The presence of other gases or substances will lower the unit’s capacity, and can cause abnormally high pressure in the refrigeration cycle. This can cause explosion and injury.

• The branching pipe must be installed horizontally. An angle of more than 10° may cause malfunction.

• DO NOT install the connecting pipe until both indoor and outdoor units have been installed.

• Insulate both the gas and liquid piping to prevent water leakage.b

• Remove the batteries in case of prolonged disuse of the remote control. 8.1.1 - Insertion of batteriesThe remote control is not supplied with batteries.To insert the batteries correctly (gure 15-16):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.8.1.2 - Replacement of batteriesThe 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/LR03X2).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.K2 ENGLISH EN - 36• 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 re. 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.

8.1.3 - Location of the remote controller

• Keep the remote control in a position from which the signal can reach the indoor unit receiver (max. distance approx. 8 metres - with the batteries charged) (gure 32). The presence of obstacles (furniture, curtains, walls, etc.) between the remote control and indoor unit, reduces the capacity of the remote control.

Below nd simple recommendations for reducing consumption:• Always and constantly keep the lters 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 ow (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.• DO NOT set the unit to excessive temperature levels.• Set a timer and use the built-in SLEEP/ECONOMY mode if applicable.• If you don’t plan to use the unit for a long time, remove the batteries from the remote control.• Clean the air lter every two weeks. A dirty lter can reduce cooling or heating efciency.• Adjust louvers properly and avoid direct airow.• Closing curtains during heating also helps keep the heat in. • Doors and windows should be kept closed.• Doors and windows must be kept closed.

8.9 - OPERATION MODE SELECTION

While two or more indoor units are simultaneously operating, make sure the modes do not conict with each other. The heat mode claims precedence over all other modes. If the unit initially started to operate in HEAT mode, the other units can operate in HEAT mode only.For example: If the unit initially started operates under COOL (or FAN) mode, the other units can operate under any mode except HEAT. If one of the unit selects HEAT mode, the other operating units will stop operation and display ”--” (for units with display window only) or the auto and operation indication light will ash rapidly, the defrost indication light will turn off, and the timer indication light will remain on (for units without a display window). Alternatively, the defrost and alarm indication light (if applicable) will light up, or the operation indication light will ash rapidly, and the timer indication light will turn off ( for the oor and standing type).

9 - MAINTENANCE AND CLEANING

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).

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

If you plan to idle the unit for a long time, perform the following:a. Activate the fan for approx. half a day to dry the inside of the unit.b. Clean the internal unit and the air lter.c. Stop the air conditioner and disconnect the power supply.d. Remove the batteries from the remote control. The outdoor unit requires maintenance interventions and periodic cleaning. DO NOT PERFORM THEM ALONE. Contact the dealer or after-sales assistance service.NEXYA S5 E ENGLISH EN - 43 Checks before resuming use of the air conditioner: a. Check that the wires are not broken or disconnected. b. Check that the air lter is clean and installed correctly. Clean the lters after a long period of inactivity of the air conditioner. c. Check that the air outlet or inlet are not obstructed (especially after a long period of inactivity of the air conditioner).

Do not touch the metal parts of the unit when removing the lter. There is a risk of injury due to the sharp metal edges.

Do not use water to clean the internal parts of the air conditioner. Exposure to water can ruin the isolation, with the risk of electric shocks.

When cleaning the unit, make sure the switch is off and the power supply is discon- nected.

9.2 - OPTIMAL OPERATION

To achieve optimal performance, please note the following:

• Adjust the direction of the air ow so that it is not blowing directly on people.

• Adjust the temperature to achieve the highest possible level of comfort. Do not adjust the unit to excessive temperature levels.

• Close doors and windows in COOL mode or HEAT mode.

• Use the TIMER ON button on the remote controller to select a time you want to start your air conditioner.

• Do not place any object near the air inlet or air outlet, as the efciency of the air conditioner may be re- duced and the air conditioner may stop running.

• Clean the air lter periodically, otherwise cooling or heating performance may be reduced.

• Do not operate unit with horizontal louvre in closed position. When the air conditioner is to be used again:

• Use a dry cloth to wipe off the dust accumulated on the rear air intake grille in order to avoid the dust being dispersed from the indoor unit.

• Check that the wiring is not broken off or disconnected.

• Check that the air lter is installed.

• Check if the air outlet or inlet is blocked after the air conditioner has not been used for a long time.

10 - TROUBLESHOOTING

10.1 - SAFETY PRECAUTIONS

If one of the following conditions occurs, switch o󰀨 and promptly disconnect the appliance.

• The power cord is damaged or heats up in an abnormal manner.

• You smell a burning odour.

• The unit emits loud or abnormal sounds.

• A power fuse blows or the circuit breaker frequently trips.

• Water or other objects fall inside the appliance.

The following problems are not a malfunction and in most situations will not require repairs. Malfunctioning Cause What must be done? The unit will not start. Current failure Wait for the current to be restored. The unit is disconnected from the current. Check that the plug is inserted in the wall socket. A fuse has blown. Replace the fuse. The remote control batteries may be discharged. Replace the batteries. The compressor 3 minute protection has activated. Wait. The unit starts and stops frequently There’s too much or too little refrigerant in the system. Check for possible leakage, contact the assistance service if that occurs. There is air, incompressible gas or foreign material in the refrigeration system. Contact the assistance service. System circuit is blocked. Contact the assistance service. The compressor is broken. Contact the assistance service. The voltage is too high or too low. Install a manostat to regulate the volt- age; contact the assistance service.NEXYA S5 E ENGLISH EN - 45 Malfunctioning Cause What must be done? L’apparecchiatura non ra󰀨redda o non riscalda bene l’ambiente mentre dell’aria esce dal condizionatore. Incorrect temperature setting. Set the temperature correctly. The air lter is clogged. Clean the air lter. The doors or windows are open. Close the doors or windows. The air inlet or outlet vents of the indoor or outdoor units are blocked. First, remove the obstructions and then re-start the unit. Temperature setting may be higher than the ambient room temperature. Lower the temperature setting. Excessive heat generated by the sunlight. Close your windows or curtains. Low cooling caused by leakage or prolonged use. Check for possible leakage, contact the assistance service if that occurs. The outdoor temperature is lower than 7°C. Check for possible leakage, contact the assistance service if that occurs. Low refrigerant due to leak or long- term use. Check for possible leakage, contact the assistance service if that occurs. Low level of refrigerant due to leakage or prolonged use. Check that there is no leakage, reseal the system and top up coolant if needed. The SILENCE function is active (op- tional). Check that there is no leakage, reseal the system and top up coolant if needed. Deactivate the SILENCE function.

10.3 - FUNCTIONAL ASPECTS NOT TO BE MISTAKEN FOR ANOMALIES

The following events may occur during normal operation:

1. PROTECTION OF THE AIR CONDITIONER.

a. The compressor will not re-start for 3 minutes after it has been switched off. - The unit is designed not to blow cold air in HEATING mode, when the internal heat exchanger is in one of the following conditions and the temperature set has not been reached. - When heating has just been started. - Defrosting. - Low temperature heating. b. The indoor or outdoor fans stop running during defrosting. - Frost may form on the outdoor unit during the heating cycle, when the outdoor temperature is low and humidity is high, which may cause lower heating efciency or air conditioning. - If this occurs, the air conditioner will stop heating mode and will automatically activate the defrosting function. - The time required to perform defrosting can vary from 4 to 10 minutes, depending on the outdoor temperature and the amount of frost that has formed on the outdoor unit.

2. WHITE MIST ESCAPES FROM THE INDOOR UNIT

- White mist may be generated due to the large temperature difference between the inlet air and the outlet air in COOLING mode in indoor environments with high relative humidity. - The white mist may be generated by the humidity produced by the defrosting process when the air conditioner re-starts in COOLING mode after defrosting.

3. SLIGHT AIR CONDITIONER NOISE

- A low hissing noise may be heard when the compressor is running, or has just been switched off. It is the noise of the refrigerant running or stopping. - A low “squeaking” noise may also be heard when the compressor is running, or has just been switched off. This is caused by expansion due to the heat or contraction due to cold of the plastic parts of the unit, when the temperature changes.ENGLISH EN - 46 - A noise may be heard due to the louvre restoring itself to its original position on commissioning.

4. DUST IS BLOWN OUT FROM THE INDOOR UNIT.

- This is normal when the air conditioner is re-started after a long period of inactivity, or is used for the rst time.

5. A STRANGE ODOUR IS DETECTED COMING FROM THE INDOOR UNIT.

- It is caused by the indoor unit, which releases the odours absorbed by the construction materials, the furnishings or from smoking.

6. THE AIR CONDITIONER GOES TO FAN ONLY MODE FROM HEATING AND COOLING MODE

- When the indoor temperature reaches the temperature set on the air conditioner, the compressor stops automatically and the air conditioner goes to fan only mode. The compressor will start again, when the indoor temperature increases in cooling mode, or lowers in heating mode.

7. POSSIBLE DRIPPING OF WATER.

- Droplets of water may form on the surface of the indoor unit when cooling is activated in high relative humidity conditions (relative humidity above 80%). Adjust the horizontal louvre to maximum opening to allow the air to escape and select high fan speed.

- The air conditioner takes heat from the outdoor unit and releases it through the indoor unit during operation in heating mode. When the outdoor temperature lowers, the heat introduced by the air conditioner consequently decreases. - Simultaneously, the air conditioner heat production load increases due to the greater difference between the indoor and outdoor temperatures. - If a comfortable temperature cannot be obtained only with the air conditioner, it is recommended to use an additional heating device.

9. AUTOMATIC RE-START FUNCTION

- The indoor unit has an automatic re-start button (auto-reset). Whenever there is unexpected power failure, the settings present at the time of the voltage drop will be restored. The unit will automatically re-activate the previous operational settings after 3 minutes from the voltage being restored.

10. LIGHTENING OR ELECTRIC EQUIPMENT

- Lightening or wireless phones working in the vicinity could cause the air conditioner to malfunction.

10.4 - TROUBLESHOOTING

1. The unit may stop running or keep running safely if:

- the LEDs keep ashing - on the display appears one of the following codes: E(x), P(x), F(x), EH(xx), EL(xx), EC(xx), PH(xx), PL(xx), PC(xx) Wait approximately 10 minutes; the problem may solve by itself. If not, disconnect power supply and reconnect it. Switch on the unit. If the problem persists, disconnect the unit from the power supply and contact the closest service centre.

2. Stop the air conditioner immediately is one of the following anomalies occurs.

Disconnect the electric power supply and contact the nearest after-sales assistance service. Problem: - The fuses blow frequently or the automatic switch intervenes often. - Water or other objects have entered the air conditioner. - The remote control does not function or functions anomalously.

The display board may show a garbled code or a code undened by the service manual. Ensure that this code is not a temperature reading. Test the unit using the remote control. - If the unit does not respond to the remote, the indoor PCB requires replacement. - If the unit responds, the display board requires replacement.NEXYA S5 E FRANÇAIS FR - 1
