Do not use your air conditioner when:

it a close to a heat source.

This air conditioner is not made for DIY repair.

HOW IT WORKS

The compressor (6) in the exterior unit compresses the refrigerant into a high- temperature, high-pressure gas. When this gas flows along the cooling fins of the condenser (7), heat is extracted and the gas condenses into a liquid, which is led to the evaporator (1) in the interior unit. The liquid expands into a gas at a low temperature and low pressure.

This gas absorbs the warmth of the air in the room, the cooled air is blown back into the room and the heat absorbed by the refrigerant gas is led to the compressor.

A fan (3) draws the air (a) over the

filter (2) and evaporator (1) and blows the cooled air (b) back into the room.

A fan (8) draws air over the condenser and blows warm air (d) away.

Heating (H-models only)

The system operates in reverse: the condenser works as an evaporator, the

evaporator as a condenser: warm air is blown into the room. This is ideal for cool days when the main heating is not on, or to supplement the main central heating in autumn and spring.

Dehumidifying

As with cooling, the moisture in the air condenses on the cold evaporator at room temperature and is drained outdoors.
