3.3 Hydraulic connection
The heat pump is supplied with two 50 mm diameter union connections. Use
PVC tubing for the 50 mm hydraulic line. Connect the heat pump water inlet to
the pipe from the filtration unit then connect the heat pump water outlet to the
water pipe going to the pool (see diagram below).
Install by-pass valve between the inlet and outlet on the heat pump.

It is advisable to install the heap pump on a separate concrete block
or on a mounting bracket designed for this purpose and to mount the
heat pump on the supplied rubber bushing (fastenings and washers not
supplied).
The maximum installation distance between the heat pump and the
swimming pool is 15 metres.
The total length of the hydraulic pipes to and from the unit is 30 metres.
Insulate both surface and buried hydraulic pipes.
If an automatic distributor or an electrolyser is used, it must be
installed after the heat pump to protect the titanium capacitor from high
concentrations of chemical products.
Make sure you install the by-pass valve and union connections supplied
to the unit’s water inlet and outlet so as to simplify purging over the
winter period, to facilitate access or dismantling for maintenance.
