▶ Clean indoor unit and remote control by wiping them with a soft cloth.
▶ Only have the outdoor unit cleaned by an approved contractor.
4.3 Cleaning the air filter
A clogged air filter will reduce performance and increase power
consumption.
WARNING
Removing and cleaning the air filter may cause damage to the unit
and/or injury
▶ Ensure that the air filter is cleaned at regular intervals.
▶ In households with animals, wipe the air grilles at regular intervals to
prevent clogging by animal hair
4.4 Decommissioning for longer periods
Before decommissioning for longer periods:
▶ Clean the air filter.
▶ Activate the self-cleaning of the indoor unit using the Clean button.
▶ After self-cleaning, switch on the fan mode until the indoor unit is dry.
▶ Turn off indoor unit and disconnect power supply.
▶ Take batteries out of the remote control.
▶ Protect the devices from dust.
4.5 Manual operation
NOTICE
Damage to units due to incorrect operation
Use of manual operation on a continuous basis is not envisaged.
▶ This must only be used for testing purposes or in emergencies.
▶ Only use for a short time.
▶ Switch off the indoor unit.
▶ Fold the top cover of the indoor unit up.
▶ Press the key for the manual cooling mode by inserting a thin object:
– Press once: unit is forced into automatic mode.
– Press twice: unit is forced into cooling mode.
– Press three times: indoor unit is switched off.

5Troubleshooting
5.1 Operating mode conflict
When using multi-split air conditioners, all operating modes are
possible, but with the following special features:
If you operate more than one indoor unit, indoor units may go into
standby due to an operating mode conflict. An operating mode conflict
occurs when at least one indoor unit is in heating mode and at least one
indoor unit is in another operation mode at the same time (e.g. cooling
mode). Heating mode always has priority. All indoor units that are not in
heating mode go into standby due to the operating mode conflict.
During operating mode conflict, the indoor unit shows “−−” in the
display.
Avoid the operating mode conflict:
• No indoor unit is in heating mode.
• All indoor units are in heating mode and/or off.
5.2 Faults with indication (Self diagnosis functionSelf
diagnosis function)
If a fault occurs during operation, the LEDs flash for an extended period
or an error code is displayed (e.g. EH 02).
If a fault is present for more than 10 minutes:
▶ Briefly disconnect the power supply and switch the indoor unit back
on.
If a fault persists:
▶ Call customer service and provide the fault code and details of the
appliance.
5.3 Faults not indicated
If faults occur during operation that cannot be eliminated:
▶ Call customer service about the fault, providing details of the device.
Fault Possible cause
The output of the indoor unit is too low. Temperature is set too high or too low.
Air filter is soiled and must be cleaned.
Unfavourable ambient conditions for the indoor unit, e.g. the ventilation openings of the devices are
obstructed, doors/windows in the room are open or the room contains powerful heat sources.
Low-noise operation is activated and prevents the full output from being used.
Indoor unit does not switch on. The indoor unit has a safety mechanism to prevent overloading. It may take 3 minutes , until the indoor
unit can be restarted.
The batteries of the remote control are empty.
The timer is switched on.
Operating mode changes from Cooling or Heating
to Fan Mode.
The indoor unit changes operating mode to prevent the formation of frost.
The set temperature is reached provisionally.
A white mist is coming from the indoor unit. In humid regions, white mist may appear if there is a significant temperature difference between the
indoor air and air-conditioned air.
White mist is emerging from the indoor unit and
outdoor unit.
If heating mode is activated directly after automatic defrosting, this can generate white mist due to the
higher level of humidity.
