Keep all safety regulations and instructions in a
safe place for future use.
Packaging:
The unit is supplied in packaging to prevent it from
being damaged in transit. The raw materials in this
packaging can be reused or recycled.
Tips on saving energy
Only use the air conditioner when you really need to.
Do not select too high a temperature for heating or
too low a temperature for cooling. Select the “Sleep”
function during the night.
Close all windows, doors and Venetian blinds in
order to reduce incoming sunlight as far as possible.
Principle of operation for cooling
Heat is extracted from the air in the room by the air
heat-exchanger (evaporator) in which the coolant
circulates. This air is conveyed to the outside air
heat-exchanger (condenser).
This gives off heat to the outdoor air. Electrical
energy is required for this. In certain circumstances
condensation may form on the evaporator on the
indoor unit, which will be removed by the
condensation hose.
