Hydraulic Connections; Electrical Connections - Polytropic XXS Manual De Instrucciones

Hydraulic connections

The heat pump should be connected to a filtration circuit trough a by-pass who consists of 3 valves.
It is imperative that the by-pass is placed after the pump and the filter.
These valves allow to regulate the water flow which passes through the heat pump and to isolate the heat pump
completely for any maintenance work, without cutting the filtration flow.
If your installation is equipped with water treatment devices (chlorine, brome feeder, salt water chlorine generator,
others) the by-pass must be installed before the water treatment devices, with a non-return check valve between
the by-pass and water treatment devices.
Water inlet and outlet are designed to be connected to rigid pressure PVC tube (for swimming pool) Ø50 mm, directly
glued to the half union connectors provided.
Inlet water tube must be connected to connection labeled:
Outlet water tube must be connected to connection labeled:
Water tubes must be fixed on the floor or the walls, so the heat pump will not support the weight of the water inside the
plumbing.

Electrical connections

Electric supply voltage and current values must correspond to the ones indicated on the heat pump.
Connection cables must to be sized according to the appliance power and installation requirements.
