Hydraulic connection

The heat pump is connected to a filtration circuit trough a by-pass.
It is imperative that the by-pass is placed after the pump and the filter.
The by-pass generally consists of 3 valves.
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
turning off the filtration flow.
If your installation is equipped with water treatment devices (chlorine,
brominates, salt...) the by-pass must be installed before the water
treatment, with a non-return valve between the by-pass and water
treatment.
Water inlet is indicated by the sticker:
