When the refrigerant tank is connected and the specified operation is
performed, the appropriate amount of refrigerant will be charged into
the system. After charging, the system will stop automatically. The
refrigerant must be charged according to the procedure described
below.
Automatic refrigerant charging procedure
1
Open the liquid and gas side stop valves completely.
2
Turn on the power of the outdoor unit and indoor units.
3
Make sure that the led on the PCB (A1P and A2P) on the
outdoor unit are as shown in the table below. This indicates that
the system is operating normally.
Led state
Throughout the manual the state of the leds is indicated as
follows:
If H2P is lit up, check the type of error based on the error code in
the remote controller and correct the error in accordance with
"12.4. Test operation" on page 19.
4
Automatically charge the refrigerant according to the procedure
described below.
4.1
Press
BS4 TEST
once.
NOTICE
National implementation of EU regulation on certain
fluorinated greenhouse gases may require to provide the
appropriate official national language on the unit.
Therefore, an additional multilingual fluorinated
greenhouse gases label is supplied with the unit.
Sticking instructions are illustrated on the backside of that
label.

CAUTION
Make sure to turn ON the power 6 hours before
starting the operation. This is necessary to warm the
crankcase by the electric heater.
Automatic charging is able to charge 6 kg/hour
refrigerant at an outside temperature of 0°C to 24 kg/
hour refrigerant at an outside temperature of 35°C.
The charging time depends on the amount of charged
refrigerant and on the outside temperature.
Automatic refrigerant charging is
NOT
possible if the
following restrictions are exceeded:
Outside temperature: 0°C DB~43°C DB
Indoor temperature: 0°C DB~32°C DB
Indoor unit connection capacity: 50%~110%
WARNING
Note that valve A must be closed!
NOTICE
When an indoor unit is connected to the refrigerant
system and the indoor unit is turned off, automatic
charging will fail.
