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.

Function principle – heating

In heating mode, heat is removed from the outdoor air by the outdoor device and fed into the indoor device. This passes the heat on to the room which it is to heat. Electrical energy is required for this. In certain circumstances condensation may be produced on the outdoor device, which must be discharged via the condensation drain on the underside of the outdoor device.

Inverter

In both modes of operation, the compressor capacity adjusts to the demand and regulates the nominal temperature with minimum temperature fluctuations. This “inverter technique” saves energy compared to conventional split air-conditioning systems.

The heat exchanger must be cleaned at least once annually. To do this, remove the air filters from the indoor device as described above.

앬 Using a vacuum cleaner or a long-bristled brush,

carefully remove any dirt deposits on the heat exchanger; this will avoid damaging the heat exchanger fins. A damaged heat exchanger will lead to higher operating costs.

앬 Take steps to ensure that you do not injure

yourself on the fin edges!

10. General notes

After pressing the start key the device is not started by the microprocessor for 3 minutes.

This is not a fault, it is for the protection of the compressor. Please have a little patience.

Crackling noises can be heard.

This is not a fault. These tension noises are caused by the contraction and expansion of the front panel in response to temperature differences.

There is an odd smell in the room.

This is not a fault. The air conditioner also circulates the transpiration from the walls, carpets, smoke, furniture and clothing in the air.

You can hear moving water.

This is not a fault. The coolant in the air conditioner may have expanded.

The air conditioner switches off during heat mode. Heat mode is not possible if the outdoor temperature is below approx. -10°C.

The outdoor device freezes if the outdoor temperature is low (below approx. -10°C).

Restarting after lengthy non-use
