3.3 Hydraulic connection
The unit is supplied with two 50 mm Ø union connections. Connect the water
inlet to the heat pump coming from the filtration group then connect the water
outlet to the heat pump at the water conduit going to the pool (see diagram
below).
Install a by-pass valve between the heat pump entrance and exit.
If an automatic distributor or an electrolyser is used, it should be
installed imperatively after the heat pump with the goal of protecting the
titanium condenser against an elevated concentration of chemicals.
Be sure to install the by-pass valve and the supplied union connections
at the water inlet and outlet level in order to simplify purging during
the winter period and to facilitate access when disassembling for
maintenance.
Water inlet Ø 50 mm
Water outlet Ø 50 mm
