HYDRAULIC CONNECTIONS

The choice and installation of components is the responsi-
bility 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,
dross or other foreign bodies which might damage the
unit.Construction of a bypass is recommended to enable
the pipes to be washed through without having to discon-
nect 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.
