To activate/deactivate the vacuum mode field setting
Description
To perform vacuum drying or a complete recharge of the outdoor unit’s internal
refrigerant piping it is necessary to activate the vacuum mode which will open
required valves in the refrigerant circuit so the vacuuming process or recharge of
refrigerant can be done properly.
To activate vacuum mode:
Activating the vacuum mode is done by operating the push buttons BS* on the PCB
(A1P) and reading the feedback from the 7‑segment displays.
Operate the switches and push buttons with an insulated stick (such as a closed
ball-point pen) to avoid touching of live parts.
