Electrical connection outdoor unit
On the outdoor unit, the electrical terminal strip is located behind the ser-
vice panel. Clamp the cables in such a way that they do not contact the
centre of the service panel or the gas valve.
Open service panel:
Loosen 3 screws, push service panel down and remove.
Follow the wiring diagram!
Before carrying out electrical work:
Make sure to install circuit breakers. Otherwise risk of electric shock.
For the power lines, use standard cables of sufficient capacity. Other-
wise there is a risk of short circuits, overheating or fire.
When installing power lines, do not apply tension to the cables. Loos-
ened connections pose a risk of cables slipping from terminals or
breaking; this can result in overheating or fire.
