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 2–17.
3 When 2–17 is reached, press the BS3 button once.
4 Change the setting to '2' by pressing the BS2 button once .
5 Push the BS3 button once.
6 When the display is not blinking anymore, press the BS3 button
again to activate vacuum mode.
To deactivate vacuum mode:
After charging or vacuuming the unit, please deactivate the vacuum
mode:
7 Press the BS2 button until you reach page 2–17.
8 When 2–17 is reached, press the BS3 button once.
9 Change the setting to '1' by pressing the BS2 button once.
10 Push the BS3 button once.
11 When the display is not blinking anymore, press the BS3 button
again to deactivate vacuum mode.
12 Press the BS1 button to leave the setting mode.
Make sure to reattach the electronic component box cover and to
install the front cover after the job is finished.
NOTICE
Make sure that all outside panels, except for the service
cover on the electrical component box, are closed while
working.
Close the lid of the electrical component box firmly before
turning on the power.
Charging refrigerant: Setup
See "4.3.1 Checking refrigerant piping:
Installation manual
12
Setup" [ 4 9].
To completely recharge refrigerant
WARNING
▪ Only use R32 as refrigerant. Other substances may
cause explosions and accidents.
▪ R32 contains fluorinated greenhouse gases. Its global
warming potential (GWP) value is 675. Do NOT vent
these gases into the atmosphere.
▪ When charging refrigerant, ALWAYS use protective
gloves and safety glasses.
Prerequisite: Before completely recharging refrigerant, make sure
the system is pumped down, the outdoor unit's external refrigerant
piping is checked (leak test, vacuum drying) and vacuum drying on
the outdoor unit's internal refrigerant piping is performed.
1 If not already done (for vacuum drying of the unit), activate the
vacuum mode (see "To activate/deactivate the vacuum mode
setting" [ 4 12])
field
2 Connect the refrigerant cylinder to the service port of the liquid
stop valve.
3 Open the liquid stop valve.
4 Charge the complete refrigerant amount.
5 Deactivate the vacuum mode (see
setting" [ 4 12]).

a If a multilingual fluorinated greenhouse gases label is
delivered with the unit (see accessories), peel off the
applicable language and stick it on top of a.
b Factory refrigerant charge: see unit name plate
c Additional refrigerant amount charged
d Total refrigerant charge
e Quantity of fluorinated greenhouse gases of the total
refrigerant charge expressed as tonnes CO
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
Formula to calculate the quantity in CO
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.
