3.4.1 Connection to the cooling water supply
ATTENTION
Outflow of cooling water can cause damage!

Connection to the cooling water supply should be carried out by a refrigeration
engineer or suitably trained plumber.

It must be ensured that suitable structural measures (leak sensor, automatic shut-
off valves) prevent damage to surrounding components in the event of a leak or
defect. These measures depend on the installation location or the structural
conditions and are the responsibility of the installer or system designer.

Ensure that the water supply pressure does not exceed the unit rating.
Notes on the water connection:

The cooling infrastructure to which the unit is connected (the external
water loop) must be appropriately dimensioned by the system
designer, taking into consideration the available pump pressure and
type, the nominal pipe diameters and the pressure loss expected in
the load circuit (the cooling module).

To avoid a pressure drop in the system, the water pipes should be
kept as short as possible.

The behavior of the materials used in the cooling module with the
materials of the external water circuit must be observed in order to
avoid corrosion damage!

When creating the on-site piping, contamination in the line system
must be avoided, or the lines must be flushed before connecting the
cooling module.

Shut-off and drain valves on each cabinet as well as a central water
filter and air separator are mandatory.
