3.7 Electrical connection
Note: Although the heat pump is electrically isolated from the rest of the swimming pool system,
this only prevents the flow of electrical current to or from the water in the pool. Earthing is still
required for protection against short-circuits inside the unit. Always provide a good earth
connection.
Before connecting the unit, verify that the supply voltage matches the operating voltage of the heat pump.
It is recommended to connect the heat pump to a circuit with its own fuse or circuit breaker (slow type;
curve D) and to use adequate wiring (see table below).
For horizontal models (Hydro Pro7, 10, 13 and 18): remove the panel to the right of the fan opening.
(Hydro Pro 5: remove the top panel).
For vertical models (Hydro-Pro22, 22T and 26T): remove the corner panel with the electronic control panel.
Connect the electrical wires to the terminal block marked ‘ POWER SUPPLY ’.
A second terminal block marked ‘WATER PUMP ’ is located next to the first one. The filter pump (max. 5 A /
240 V) can be connected to the second terminal block here. This allows the filter pump operation to be
controlled by the heat pump.
Note: In the case of three-phase models, swapping two phases may cause the electric motors to run in the
reverse direction, which can lead to damage. For this reason, the unit has a built-in protective device that
breaks the circuit if the connection is not correct. If the red LED above this safety device lights up, you
must swap the connections of two of the phase wires .
