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.
