Remarks:
The factory only provides the heat pump. Other parts, including a contingent by-pass are to be
provided by the user or installer.
Attention:
Please take the following steps when installing the heat pump:
Each addition of chemicals has to be performed through the conduits located AFTER the heat pump.
Install a by-pass for easy maintenance
Always place the heat pump on a solid base and use the supplied silent blocks in order to avoid
vibrations and noise.
Always keep the heat pump in upright position. If the unit has been tilted, you should wait for at least
24 hours before turning it on.

3.4 Installation of a check valve
When using automatic chlorine and pH dosage systems, it is of uttermost importance to protect the heat
pump from high concentrations of these chemicals that could corrode the heat exchanger Therefore,
such systems should add the chemicals in the conduits located DOWNSTREAM of the heat pump and
it is recommended to install a check-valve in order to prevent back-ow when there is no water circulation.
Damage to the heat pump caused by disregarding any of these recommendations will invalidate the warranty.
3.5 Electrical Wiring
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 (C-curve) as well as adequate wiring
(see table below). Connect the electrical wires with the terminal block labeled 'TO POWER SUPPLY'
Next to this connection, there is a second terminal block labeled 'TO PUMP', to which the lter pump
(max. 5A/240V) or an electrical relay for a ltration pump can be connected. This connection makes it
possible to control lter pump operation with the heat pump.
However, we do not recommend that you wire the pool circulation pump to the heat pump.Run separate
power supplies to the heat pump and the pool circulation pump. This allows the pool circulation pump to
be put on a time clock and operated for the required time to give adequate ltration for the pool and also
the pool circulation pump can be manually operated when required to backwash the lter etc.
