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.
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 by changing the setting back to '0'.
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 switch box, are closed while working.
Close the lid of the switch box firmly before turning on the
power.

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 "7.4.2 To activate/deactivate the vacuum
setting" [ 4 14])

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 14]).

Formula to calculate the quantity in CO
tonnes: GWP value of the refrigerant × total refrigerant

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

To insulate the refrigerant piping

After finishing the charging procedure, the piping must be insulated.
Take into account the following points:
▪ Be sure to insulate the liquid and gas piping (for all units).
▪ Use heat resistant polyethylene foam which can withstand a
temperature of 70°C for liquid piping and polyethylene foam which
can withstand a temperature of 120°C for gas piping.
▪ Reinforce the insulation on the refrigerant piping according to the
installation environment.
