Check the tightness of the couplings by
applying some soap and water. Check that
there are no bubbles.
Recheck the tightness and retighten the
couplings
again
12-24
hours
after
installation. Check the tightness by wetting
with soapy water. Check also the couplings
at the indoor unit. If there are no bubbles, the
couplings
are
correctly

and
tightened.
Electrical connection - indoors
IMPORTANT
Never connect the power before the wiring arrangement below is connected and the protective covers are
refitted. The system is connected to the mains supply with a plug, i.e. it requires no intervention in the
electrical system in the house.
Electrical connection – outdoor unit
Unscrew the cover in front of the terminal block on the outdoor unit.
Press the connectors together and fit the cable with the help of a strain reliever.
Note that the cable from the indoor unit must be fitted under the strain reliever.
