EU heat pumps

3.7 Electrical hook-up
Important - Although the heat pump is electrically isolated from the rest of the unit, this only prevents
the passage of electricity to or from the pool water. Grounding the unit is still required to protect yourself
from short circuits inside the unit. Make for adequate ground connection.
Check if the electrical mains voltage corresponds with the operating voltage of the heat pump prior to hooking
up the unit.
It is recommended to use a separate fuse (slow type – D-curve) as well as adequate wiring (see table below).
Connect the electrical wires with the terminal block labelled ‘TO POWER SUPPLY’.
Next to this connection, there is a second terminal block labelled ‘TO PUMP’, to which the filter pump (max.
5A/240V) can be connected. This connection makes it possible to control filter pump operation with the heat
pump. See further under paragraph 4.2 (parameter 9) for the different possibilities.
Remark – For models with 3 phases, switching 2 phases may cause an inversion in the rotational direction of
electrical motors, which could damage the unit. Therefore, a protection device has been built in, which will
interrupt the circuit if the connection has not been performed correctly. If you see a red LED light up at the top
of this protection device, 2 phase wires have to be switched.
