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%
Automatic refrigerant charging procedure
1
Open the liquid and gas side stop valves completely.
WARNING
Note that valve A must be closed!
2
Turn on the power of the outdoor unit and indoor units.
NOTICE
When an indoor unit is connected to the refrigerant
system and the indoor unit is turned off, automatic
charging will fail.
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.
H1P H2P H3P H4P H5P H6P H7P
Led state
Throughout the manual the state of the leds is indicated as
follows:
OFF

ON or OFF
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.
DANGER: RISK OF ELECTROCUTION
Do not touch anything else than the push-buttons (BS1~5)
on the PCB (A2P) when making the settings. These
settings must be done with the power ON.
