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
▪ When a malfunction is detected during the procedure
(e.g., in case of closed stop valve), a malfunction code
will be displayed. In that case, refer to
codes when charging refrigerant" on page 16
and
solve the malfunction accordingly. Resetting the
malfunction can be done by pushing BS3. You can
restart the "Charging" instructions.
▪ Aborting the manual refrigerant charge is possible by
pushing BS3. The unit will stop and return to idle
condition.
10
Open valve A.
11
Charge refrigerant until the remaining determined additional
refrigerant amount is added, and then close valve A.
12
Press BS3 to stop the manual additional refrigerant charge
mode.
NOTICE
Make sure to open all stop valves after (pre-) charging the
refrigerant.
Operating with the 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 13.9 N•m.
5.6.4
Error codes when charging refrigerant
INFORMATION
If a malfunction occurs, the error code is displayed on the
user interface of the indoor unit.
If a malfunction occurs, close valve A immediately. Confirm the
malfunction code and take corresponding action,
problems based on error codes" on page 24

NOTICE
In Europe, the
greenhouse gas emissions
of the total
refrigerant charge in the system (expressed as tonnes
CO
2
-equivalent) is used to determine the maintenance
intervals. Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000

Fix the label on the inside of the outdoor unit. There is a
dedicated place for it on the wiring diagram label.

Guidelines when knocking out knockout
holes
NOTICE
Precautions when making knockout holes:
▪ Avoid damaging the casing.
▪ After making the knockout holes, we recommend you
remove the burrs and paint the edges and areas
around the edges using repair paint to prevent rusting.
▪ When passing electrical wiring through the knockout
holes, wrap the wiring with protective tape to prevent
damage.
