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.

Principle of operation for 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.

Page 13

time intervals listed below should be maintained in most cases.

Keep the outdoor device and the area around the outdoor device clean. Regularly remove leaves, etc. which can collect around the outdoor device.

Cleaning the housing of the indoor device

앬 Clean the housing of the indoor device using

only a soft, wet cloth when necessary.

앬 In order to avoid damaging the housing and

electronics, avoid the use of gasoline, thinners, scouring powder, cleaners and the like when cleaning.

Cleaning the air filters of the indoor device

Make sure that the air filters are clean! Soiled air filters reduce the air output of the device. The air filters of the indoor device should be checked and, if necessary, cleaned on a monthly basis.

1. Raise the front panel of the indoor device until the panel audibly clicks into position in its open position (Fig. 13).

2. Raise the air filter slightly using the handle (Fig.

14) to take the filter out of the filter holder and then pull it downwards to remove it. Take the air filter out of the indoor device (Fig. 15).

3. Clean the netting in the air filter with a vacuum cleaner or wash it out with water.

4. Then dry the filter in a cool place.

5. Place the top part of the air filter back into the device and ensure that its left and right edges are correctly aligned. Then insert the filter in full (Fig. 16).

6. Close the front panel again.

Cleaning the heat exchanger of the indoor device

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!

11. General notes

Restarting after lengthy non-use

If the air-conditioning system has not been used for a lengthy period, check the following before you switch it on:

1. there are no objects covering the outdoor or

indoor unit.

2. the socket from which the unit is operated has been installed correctly

3. the air filters are clean

Care precautions

If the air conditioner is not going to be used for some period of time:

1. Let the fans run for 6 hours to allow the device to completely dry out. Set the highest possible temperature level while the fans are running.

2. Switch off the device and pull the power plug.

3. Clean the air filters and housing parts.

4. Remove all dirt from the outdoor unit.

5. Take the batteries out of the remote control.

If the following events occur during operation, they do not constitute a fault.

1. Safety function of the air conditioning system,

compressor trip

a) After the system has been switched on again,

the compressor will not cut in until after a delay of three minutes.

b) The device has a special function that prevents

cold air being blown out in heat mode if the heat exchanger in the indoor device is in one of the following situations and the set temperature has not yet been reached: – Heat mode has just been started. – De-icing taking place. – Heat mode with a low temperature setting.

c) The internal and external fans will be shut down

during de-icing. De-icing is taking place.

d) If the outdoor temperature is high and the

humidity is high, the outdoor device may ice up whilst it is operating. This will result in reduced heat output by the air conditioning system. If this is the case the air conditioning system will terminate heat mode and start de-icing mode automatically. The de-icing time may be 4 – 10 minutes depending on the outdoor temperature and the amount of ice deposited on the outdoor device.

2. “White mist” is emitted from the indoor device

a) If the temperature difference between the air inlet

and air outlet is large and the relative humidity in the room is also high. “white mist” may be generated in cool mode.

b) If the air conditioning system is restarted in heat

mode after de-icing, “white mist” may be generated by moisture in certain circumstances.

Anleitung_Dual_Split_2500_C_H_GB:_ 24.01.2008 8:17 Uhr Seite 13

Page 14

3. A low noise is emitted by the air conditioning system

a) When the compressor is running or shortly after

it has been switched off, a hissing noise may be heard, caused by the refrigerant flowing through the pipes.

b) When the compressor is running or shortly after

it has been switched off, a “screeching” noise may be audible, caused by the heat expansion and cold contraction of the plastic parts in the device due to temperature changes.

c) The first time the power supply is switched on,

the air flap will return to its initial position.

4. Dust is blown out of the indoor device

a) This is normal if the air conditioning system has

been switched off for a lengthy period of time and when it is started for the first time.

5. A strange odor emanates from the indoor device

a) This odor is generated in the indoor device and

is emitted by certain materials or pieces of furniture or by cigarette smoke.

6. The air conditioning system switches to exclusive fan mode from cool or heat mode

When the indoor temperature has reached the set temperature, the compressor will cut out automatically and the air conditioning system will be operated in FAN mode. As soon as the indoor temperature in COOL mode rises above the set value or in HEAT mode it falls under the set value, the compressor will cut in again.

7. In rooms with high relative humidity (over 80%), water droplet are deposited on the surface of the indoor device in cool mode

Set the horizontal air flap to the vertical air outlet position and select a HIGH fan speed.

8. Heat mode

In heat mode, the air conditioning system draws in warm air from the outdoor device and dissipates it through the indoor device to the indoor area. If the outdoor temperature falls, the volume of hot air drawn in through the air conditioning falls accordingly. At the same time the heat load of the air conditioning system increases as a result of the large difference between the indoor and outdoor temperature. This may result in the air conditioning system being unable to achieve an adequate room temperature. Please note that the heat function is only really suitable for use during autumn and spring.

9. A lightning strike or the mobile phone in a car

in use near the system may cause faults in the device

In this case disconnect the deviceʼs power supply briefly and then reconnect it. Press the ON/OFF button on the remote control to restart the device.

12. Troubleshooting

Device does not start. Check the following:

1. Is voltage present at the plug socket outlet?

2. Check the plug fuse!

3. Is the timer set?

The device does not provide satisfactory cooling! Check the following:

1. Has an appropriate temperature been set?

2. Is the air filter soiled? Clean and fit back in place.

3. Are the inlets and outlets on the outdoor device

blocked?

4. Has the sleep mode been set during the day?

5. Are the connections between the indoor and

outdoor device adequately sealed? There may not be enough coolant? If so, please contact your service company.

The remote control does not work! (Important! It only works within a range of 8 m from the indoor device.)

1. Are the batteries still OK? Replace if necessary!

2. Have the batteries been inserted correctly? Check that the + and – terminals are correct!
