IMPORTANT!
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.
Instructions for high comfort,
low consumption operation
For maximum comfort and minimum consumption
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
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).
