For maximum comfort and minimum con-
sum tion
Maintain the room at a comfortable tem-
perature.
Avoid opening doors and windows more
than necessary.
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.
When using the appliance in cooling mode,
try to prevent direct sunlight from heating
up the room. Draw the curtains.
Have the filter cleaned by qualified person-
nel. Make sure that it is replaced correctly
inside the appliance (see Table II).
Periodically clean the intake grille and the
area around the outdoor unit to maintain
correct air flow.
If you are not going to use the appliance for
an extended period of time, carefully follow
the instructions below. lean the indoor
unit and the area around it.

IMPORTANT!
During functioning in heat pump heating mode, the unit performs defrost cycles to elimi-
nate any ice that might form at low temperatures inside the outdoor unit. During defrost-
ing, the indoor fan is automatically switched off and does not start up again until defrost-
ing has been completed.
Controls
The unit can be used with an infra-red remote control, or with the cabled “Room ontroller”
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.

Maintenance and dis osal
Warning!
• The a liance must be maintained and cleaned internally only by qualified erson-
nel.
• Always disconnect the a liance from the mains su ly before starting any main-
tenance work and before accessing any internal com onents.
Perform the various cleaning and maintenance operations at the intervals specified in the
following table.
Table II: Scheduled maintenance
Indoor unit Every month Every 4 months Every year
lean the air filter (1) √
lean the condensate drain pipe (1) √
hange 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 erformed
only by qualified ersonnel)
The air conditioner fails to start:
• The main switch is turned off. Turn the
switch ON.
• The fuses in the main switch have burned
out. hange 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).
• heck that the condensate pump (if fit-
ted) is not in alarm state and that the level
of water in the condensate bowl is not too
high.

GB-8
Very oor air conditioning efficiency:
• The air flow to or from the indoor or out-
door 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.
Mist comes out of the unit:
• 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 air conditioner whistles briefly
when it is switched on or off.
• This is caused by the coolant starting to
circulate and pressure equalising inside
the coolant circuit. It is normal and stops
quickly.
The unit emits an un leasant 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 autho-
rised service centre to have the filters
changed. Re-start the appliance in ventila-
tion mode and open the windows to
change the air.
Dis osal
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 appli-
ance’s useful life, have the appliance and
all its components processed and dis-
posed of by a proper disposal service.
