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.
19.6 Error codes when charging refrigerant
INFORMATION
If a malfunction occurs, the error code is displayed on the outdoor unit's 7‑segments
display and on the user interface of the indoor unit.
If a malfunction occurs, close valve A immediately. Confirm the malfunction code
and take corresponding action, "26.3 Solving problems based on error

applicable language and stick it on top of a.
b Factory refrigerant charge: see unit name plate

f GWP = Global warming potential
NOTICE
Applicable legislation on fluorinated greenhouse gases requires that the refrigerant
charge of the unit is indicated both in weight and CO
2
equivalent.
Formula to calculate the quantity in CO
2
equivalent tonnes: GWP value of the
refrigerant × total refrigerant charge [in kg] / 1000
Use the GWP value mentioned on the refrigerant charge label. That GWP is based on
the current legislation on fluorinated greenhouse gases. The GWP mentioned in the
manual might be outdated.
2 Fix the label on the inside of the outdoor unit. There is a dedicated place for it
on the wiring diagram label.
