Rittal Liquid Cooling Package

Commissioning checklist
Rittal GmbH & Co. KG hopes that this checklist will
help its customers and cooperation partners install
and operate the products of the Liquid Cooling
Package family successfully.
Before the installation:
Are shut-off valves installed in the flow and return?
These valves serve to facilitate exchange or mainte-
nance of the Liquid Cooling Package without the
need to shut off the entire cold water supply.
Is there a Taco-setter installed in the return of each
Liquid Cooling Package?
The tacho setter ensures a constant volumetric flow
and helps to maintain the hydraulic balance of the
system, especially when operating with other types
of units, such as convectors.
Is the water supply properly insulated?
Proper insulation protects against condensate for-
mation, especially on the cooling water flow pipe-
work.
Are the allowable bend radii of the hoses adhered to?
The hoses must not be kinked too tightly, otherwise
the flow volume may be impaired and the materials
may fatigue prematurely.
Is there a good water supply available which meets
the quality requirements?
Water quality determines the lasting reliability of the
system. It ensures that no undesirable corrosion or
harmful deposits will occur. The exact manufactur-
er's recommendations regarding water quality are
found in section 16.2 "Characteristic curves". The
recommended water quality should be ensured
even after the installation.
Was the pipework sufficiently flushed before the
Liquid Cooling Package was connected?
It is important to clean or flush the water circuits ap-
propriately, especially for new installations. Experi-
ence has shown that there are often remnants of
sealants, lubricants, and even metal chips in new
systems, which may lead to a premature failure of
the Liquid Cooling Package. Cleaning the cold wa-
ter system carefully before connecting the Liquid
Cooling Package ensures reliable operation later.
Note:
If the pipework for the Liquid Cooling
Package is carried out according to the
Tichelmann principle, a Taco-setter is not
necessary.
