Rittal Liquid Cooling Package Plus
6.4.2 Cooling water connection
The Liquid Cooling Package Plus is connected to the cold water network via
two 1" threaded pipe connections (external thread) on the inlet and return, lo-
cated on the lower rear side of the unit. The connecting pieces of both pipes
are composed of T pieces, to allow for the option of connecting from the rear or
through the raised floor.

Note:
As much as possible, use armoured hoses for the cooling water hoses.
The water connection may be made in a fixed manner using solid pipes as
well. This may be done locally by the appropriate qualified person.
Note:
When tightening the coupling connection, use an appropriate tool to provide
counter-support on the primary connection to ensure over-tightening is not
performed (on the Liquid Cooling Package Plus and on the building ser-
vices).
