3.3 Electrical connection
Important: The electrical connection of your heat pump must be carried out by
someone qualified to do it. Check that the cable supplying the machine room is
rated for the additional current required by the pump.
The heat pump must be powered from a separate D-curve circuit breaker which may be
either on the main electrical panel fitted with a differential circuit breaker or on an
independent panel connected to the main switchboard, with a differential circuit
breaker. If this is not the case add a differential circuit breaker to the heat pump's
independent panel.
Cable cross-section as a function of
the distance between the circuit-
breaker and the heat pump
< 10m 10 to 15m > 15m
