Electrical wiring
For the electrical connection of the heat pump use the connectors L, N and grounding.
Verify the local power supply and the operating voltage of the heat pump. It is
recommended to use a separate circuit breaker (slow type
–
D curve) for the heat pump
together with the proper wiring characteristics. The current to the heat pump should only
be applied when the filter pump is running. For example, a relay controlled by the filter pump
could be used to activate the current to the heat pump. Connect the electrical supply to the
junction box inside the heat pump. All heat pumps require a single-phase connection.
Grounding the heat pump is required to protect you against electrical shocks caused by an
eventual short circuit inside the heat pump.
The heat pump is equipped with a flow for water flow detection. If the water flow to the
heat pump stops or is insufficient, the heat pump will also stop.
The heat pump is not equipped with a plug. The heat pump need to be connected straight
into the electrical casing circuit breaker.
