6.6.6 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.
1 When the unit is powered on and not running, hold down the
BS1 pushbutton for 5 seconds.
Result: You will reach the setting mode, the 7 segment display
will show '2 0 0'.
2 Press the BS2 button until you reach page 2–28 .
3 When 2–28 is reached, press the BS3 button once.
4 Change the setting to ' 1 ' by pressing the BS2 button once .
5 Push the BS3 button once
