Try to avoid placing appliance under a tree or exposed to water or mud, which
would be likely to complicate maintenance.
Water connection
The heat pump is connected to a filtration circuit with 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.
This makes it possible 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 flow of filtration.
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.
