to mount the heat pump on the supplied rubber bushing.
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.

Install by-pass valve between the inlet and outlet on the heat pump, see
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.
