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.
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. Automatic restart function: The device shuts
down complete in the event of a power failure
during operation
The OPERATION display flashes on the indoor
device after the power supply returns. Press the
ON/OFF button on the remote control to restart the
device.
10. 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.
