If Then
a The determined
additional refrigerant
amount is not reached
yet
Close valve B and disconnect the
manifold from the liquid line.
Continue with the "Charging
refrigerant" procedure as described
below.
b The determined
additional refrigerant
amount is reached
Close valve B and disconnect the
manifold from the liquid line.
You do not have to perform the
"Charging refrigerant" instructions
described below.
c Too much refrigerant is
charged
Recover refrigerant.
Disconnect the manifold from the
liquid line.
You do not have to perform the
"Charging refrigerant" instructions
described below.
Make sure to keep ONLY gas and liquid stop valves open during
operation. In case of multi outdoor unit system, also open equalising
stop valve.

INFORMATION
For a multi outdoor unit system, it is not required to
connect all charge ports to a refrigerant tank.
The refrigerant will be charged with ±1kg per minute.
If you need to speed up in case of a multiple outdoor
system, connect the refrigerant tanks to each outdoor unit.
NOTICE
The refrigerant charging port is connected to the piping
inside the unit. The unit's internal piping is already factory
charged with refrigerant, so be careful when connecting
the charge hose.
Prerequisite: Turn on the power of the indoor units and outdoor
unit.
6 Activate setting [2‑20] to start the manual additional refrigerant
charge mode. For details, see "18.1.8 Mode 2: field
settings"[446].
Result: The unit will start operation.
7 Open valve A and charge refrigerant until the remaining
determined additional refrigerant amount is added, and then
close valve A.
8 Close valve A and press BS3 to stop the manual additional
refrigerant charge mode.
INFORMATION
The manual refrigerant charge operation will automatically
stop within 30 minutes. If charging is not completed after
30 minutes, perform the additional refrigerant charging
operation again.
INFORMATION
After charging refrigerant:
▪ Record the additional refrigerant amount on the
refrigerant label provided with the unit and attach it to
the backside of the front panel.
▪ Input the additional refrigerant amount into the system
via setting [2‑14].
▪ Perform the test procedure described in
"19Commissioning"[448].
NOTICE
Make sure to open ONLY liquid and gas stop valves after
(pre-) charging the refrigerant.
Operating with the liquid and gas stop valves closed will
damage the compressor.
NOTICE
After adding the refrigerant, do not forget to close the lid of
the refrigerant charging port. The tightening torque for the
lid is 11.5 to 13.9N•m.
16.6 Error codes when charging
refrigerant
If a malfunction occurs, close valve A immediately. Confirm the
malfunction code and take corresponding action, "22.1 Solving
problems based on error codes"[452].
16.7 Checks after charging refrigerant
▪ Are ONLY liquid and gas stop valves open?
▪ In case of multi outdoor unit system, is the equalising pipe stop
valve open?
▪ Is the amount of refrigerant, that has been added, recorded on the
refrigerant charge label?
NOTICE
Make sure to open ONLY liquid and gas stop valves after
(pre-) charging the refrigerant.
Operating with the liquid and gas stop valves closed will
damage the compressor.
