Hydraulic connection
Before carrying out any work, remember it is vital that all the valves are closed.
As you can see from the connection diagram, you need to install a BYPASS valve (if you
do not already have one) between the filtration system and the water treatment system
(or discharge).
Upstream of this BYPASS, an OUT pipe with a shut-off valve will be connected to the
water inlet of the heat pump and a RETURN pipe with a shut-off valve will be connected
to the water outlet of the heat pump.
Use the PVC connectors provided in the accessory kit to connect the hoses to the heat
pump. On the pump side, fasten the supplied fittings using Teflon tape to ensure a good
seal.
Important: Before filling the pump with water, we recommend washing/rinsing
the filter.
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.
