Hydraulic Connection - Hayward Pool ENERGYLINE PRO serie Einbau- & Anleitungshandbuch

3. INSTALLATION AND CONNECTION (continued)
It is advised to install the unit on a dissociated cement block or a
mounting bracket designed for this use and to set up the unit on the
supplied rubber bushing (fastenings and washers not supplied).
The maximum installation distance between the unit and the swimming
pool is 15 metres.
The total length of the piping to and from the unit is 30 metres.
Insulate both the above ground and buried hydraulic piping.

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.
