INSPECTION AND MAINTENANCE
Frequently check whether all couplings are properly tightened. Also check that there are no leaks. The dust
lter at the backside of the unit should be checked every 10-12 weeks for dust accumulation. If the lter has
a layer of dust, the dust should be removed using a vacuum cleaner.
The carbon lter should be replaced every 10-12 weeks in order to guarantee proper operation of the unit.
This is essential and should not be forgotten! If this is not carried out, the lter will break down sooner than
normal. To replace the carbon lter, you rst have to remove the dust lter.
Note : If you want to work with a humidifier, make sure that it is connected to a reverse osmosis filter or
scale filter. Fan faults caused by lime deposits are not covered under the warranty.
If the dust lter is still clogged with white particles when using a humidier in conjunction with a scale lter,
then an osmosis lter is required. The water is too hard to use with a scale lter. There is no need to use a
humidier if the space is not too large.
FAULT ANALYSIS AND ERROR MESSAGES
If the unit does not switch on and the remote control display and the LEDs on the printed circuit-board are off,
most likely there is no power supply. It is also possible that the internal fuse has blown. This fuse is located
near the printed circuit-board in a synthetic housing.
If there is power (the LED on the printed circuit-board ashes and the remote control display shows E:01), but
the unit does not switch on, two of the three phases should probably be switched. It does not matter which
ones of the three phases are switched.
If the fuse circuit breaker burst when the unit has to start cooling, most likely a fuse of the wrong value or
incorrect type was installed. Check the technical specications (page 8) for the correct details.
If the unit makes strange noises or is cooling poorly, check the manometer to ensure that the pointer is not
pointing too far to the right from the centre of the screen and check that the outdoor temperature (C:07) does
not exceed 50°C.
If that is the case, make sure that the outdoor unit receives more / colder air and check whether the pointer
of the manometer drops.
If water drips from the sides of the unit, you have a problem with the condensation water drainage. Check
whether the unit has sufcient fall (see the Mounting section) using a spirit level. It is also possible that the
condensation hose has too many loops/bends or is blocked.
