d) Hydraulic connection
The choice and installation of components is the responsibility of the installer who should follow good
working practice and current legislation. Before connecting the pipes, make sure they do not contain stones,
sand, rust, or others which might damage the unit. Construction of a bypass is recommended to enable the
pipes to be washed through without having to disconnect the unit (see drain valves). The connection piping
should be supported in such a way as to avoid it weighing on the unit. It is recommended that the following
devices are installed in the water circuit of the evaporator. A hydraulic safety valve shall be mounted in water
system, which should open constantly.
