The appliance must be switched off at the remote control. Never switch off the appliance by disconnecting it from the mains power supply. English Instructions for high comfort, low consumption operation For maximum comfort and minimum consumption Table II). Periodically clean the intake grille and the area around the outdoor unit to maintain correct air flow (see fig. 6). If you are not going to use the appliance for an extended period of time, carefully follow the instructions below. Clean the indoor unit and the area around it. Operate the appliance in ventilation mode for half a day to dry the inside of the unit (see fig. 7). Switch the appliance off and then disconnect it from the mains power supply (see fig. 8). Remove the batteries from the remote control (if relevant) (see fig. 9). Clean the outdoor unit (see fig. 10). Maintain the room at a comfortable temperature (see fig. 1). Avoid opening doors and windows more than necessary (see fig. 2). Do not obstruct the indoor unit’s intakes or outlets. This not only reduces efficiency by reducing the air flow, but can also lead to the malfunction (see fig. 3). When using the appliance in cooling mode, try to prevent direct sunlight from heating up the room. Draw the curtains (see fig. 4). Have the filter cleaned by qualified personnel. Make sure that it is replaced correctly inside the appliance (see fig. 5 and System description System description See the relevant installation manuals for information on how to install the indoor and outdoor units. This air conditioning system is made up of an indoor unit and an outdoor unit, inter-connected by coolant pipes and electrical cables (see fig. 11). The appliance is fitted with the safety devices listed in Table I on Page 7 below to ensure maximum comfort and efficient functioning under all weather conditions.

During functioning in heat pump heating mode, the unit performs defrost cycles to eliminate any ice that might form at low temperatures inside the outdoor unit. During defrosting, the indoor fan is automatically switched off and does not start up again until defrosting has been completed. 40 DMC

English Controls The unit can be used with an infra-red remote control, or with the cabled “Room Controller” or “Zone Manager” remote controls. See the remote control’s own manual for information on how to operate the infra-red or cable remote control. Remote controls must be installed by qualified personnel. “IR remote control” (see fig. 12). “Room Controller” (see fig. 13). “Zone Manager” (see fig. 14). Maintenance, Trouble - shooting and disposal Warning!

• The appliance must be maintained and cleaned internally only by qualified personnel.
• Always disconnect the appliance from the mains supply before starting any maintenance work and before accessing any internal components. Perform the various cleaning and maintenance operations at the intervals specified in the following table. Table II: Scheduled maintenance Indoor unit Clean the air filter (1) Every month Every 4 months Every year

Clean the condensate drain pipe (1)

Change the batteries in the infra-red remote control (if present)

Perform the above maintenance operations at least at the intervals specified to keep the appliance functioning efficiently. Maintenance intervals should obviously be adapted to the conditions of each installation, e.g. the amount of dust in the atmosphere etc.. (1) These operations must be performed only by qualified personnel. See the relevant “Installation Manual”. Trouble-shooting (any subsequent maintenance must be performed only by qualified personnel) Mist comes out of the unit: The air conditioner fails to start: The air conditioner whistles briefly when it is switched on or off:

• The main switch is turned off. Turn the switch ON.
• The fuses in the main switch have burned out. Change the fuses.
• Wait three minutes. The compressor start-up delay has not finished.
• The temperature setting is higher than the actual room temperature in cooling mode, or lower than it in heating mode (so the thermostat does not request functioning).
• Check that the condensate pump (if fitted) is not in alarm state and that the level of water in the condensate bowl is not too high.

• This is caused by the coolant starting to circulate and pressure equalising inside the coolant circuit. It is normal and stops quickly.

• This can occur when the appliance is functioning in cooling mode. It is caused by cold air from the air conditioner coming into contact with warm, humid air in the room. The unit emits an unpleasant smell:
• Unpleasant smells can build up in the indoor unit’s air filter and be blown into the room when the appliance is functioning. Switch the appliance off and call an authorised service centre to have the filters changed. Re-start the appliance in ventilation mode and open the windows to change the air. Very poor air conditioning efficiency:
• The air flow to or from the indoor or outdoor unit is obstructed.
• The air filter is dirty and is restricting the air flow. The filter must be cleaned only by qualified personnel.
• A door or window is open.
• Fan speed is on a low setting.
• The temperature setting is not suitable.

40 DMC Disposal The coolant in the appliance must be recovered and disposed of by qualified personnel before the appliance itself can be disposed of. At the end of the appliance’s useful life, have the appliance and all its components processed and disposed of by a proper disposal service. Italiano . Room Controller Fig. 14 . Zone Manager .
