Service 5. Service 5.1 Anomalies and solutions In case of problems, run the following checks before contacting a Technical Assistance Service. Anomalies Possible causes Solutions Unsatisfactory cooling performances The set temperature could be higher Set a lower temperature than the room temperature The heat exchanger of the indoor or outdoor unit is dirty Clean the heat exchanger (Service Centre) The air inlet or outlet of the outdoor unit is obstructed Switch the unit off, eliminate the cause of the obstruction and switch the air conditioner on again Door and windows open Close the doors and windows while using the unit Sunlight generates excessive heat Draw the curtains and close the windows during the hottest hours of the day or when the sunlight is more intense Too many sources of heat in the room Reduce the sources of heat (people, computers, electronic devices, etc.) Low refrigerant level due to leakages or extended use Check that there are no leakages, reseal the system if necessary and top up the refrigerant (Service Centre) The unit does not work Power shortage Wait for electricity to be restored The unit is switched off Switch the appliance on The fuse has blown Replace the fuse (Service Centre) The timer is active Deactivate the timer The unit starts or stops frequently Unsatisfactory heating performances There is too much or too little refrigerant in the system Incompressible gas or humidity has entered the system. The compressor is faulty The voltage is too high or too low The outdoor temperature is extremely low Cold air seeps in from doors and windows Low refrigerant level due to leakages or extended use Check that there are no leakages and top up the refrigerant if necessary (Service Centre) Purge the system and recharge the refrigerant (Service Centre) Replace the compressor (Service Centre) Install a voltage regulator (Service Centre) Use an auxiliary heating appliance Close the doors and windows while using the unit Check that there are no leakages, reseal the system if necessary and top up the refrigerant (Service Centre) NOTE: if, after performing the checks and diagnostics procedures described above, the problem persists, switch the unit off immediately and contact a Technical Assistance Service. 34 / EN

Service 5.2 Cleaning and inspecting the indoor unit Only use a soft and dry cloth to clean the unit. If the unit is very dirty, it is possible to use a cloth dampened with lukewarm water. Check that the drainage pipe is laid according to the instructions. If not, water leakages may occur resulting in material damages and the risk of fire and electrocution. 5.3 Cleaning and inspecting the outdoor unit Only use a soft and dry cloth to clean the unit. If the unit is very dirty, it is possible to use a cloth dampened with lukewarm water. If the evaporator (1) of the outdoor unit is clogged up, remove all leaves and debris, then clean off all dust with a water jet or some water. Repeat the same procedure with the front grille (2). 5.4 Disposal The manufacturer is registered with the national EEE Register, in conformity to the implementation of Directive 2012/19/EU, and of the relative national regulations in force concerning waste electrical and electronic equipment. This directive recommends the correct disposal of waste electrical and electronic equipment. Equipment bearing the crossed-out wheelie bin symbol must be disposed of at the end of its life and sorted to avoid detrimental effects on human health and on the environment. Electrical and electronic equipment must be disposed of together with all its constituent parts. To dispose of “domestic” electrical and electronic equipment, the manufacturer recommends contacting an authorised dealer or an authorised ecological facility. The disposal of “professional” electrical and electronic equipment must be made by authorised personnel through the specially instituted local consortiums. To this aim, we include below the definition of domestic WEEE and professional WEEE. WEEE deriving from households: WEEE deriving from households and WEEE deriving from commercial, industrial, institutional and other sources, similar by nature and quantity, to that deriving from households. WEEE that could be used both by households and by other types of users are nonetheless regarded as WEEE coming from households; Fig. 74 Professional WEEE: all WEEE other than that coming from households as mentioned above. This equipment may contain: – Refrigerant gas that must be fully recovered by specialised personnel and accompanied by the necessary authorisations in special containers; – Lubricant oil contained in compressors and in the refrigeration circuit that must be collected; – Mixtures with anti-freeze liquids contained in the water supply distribution network, the contents of which must be appropriately collected; – Mechanical and electrical parts that must be sorted and disposed of in an authorised manner. When machine components are removed for being replaced for maintenance purposes or when the entire unit reaches the end of its life and must be removed from the installation, we recommend sorting the waste according to type and ensuring that it is disposed of by authorised personnel at the existing waste collection facilities.
