Operating and Maintenance Instructions – 6 Installation – "Getting Started"
Rittal Liquid Cooling Package Plus
Optionally, the cooling water connection may be made from below through the
raised floor. This may be done through a built-in T piece.

In case of a low water inlet temperature (<12 °C), the inlet and return lines
should be appropriately insulated. If this is not done, condensate may form on
the supply lines.

Note:
It is possible to test the flow of the water cycle immediately after connection
on the graphical display (touchscreen). In addition, you must first check
whether the control valve is completely open (see Chapter 6.6.2, "Operation
in stand-alone mode"). If the control valve is closed or only partially open, it
can be opened in manual mode over a network connection using the setup
screen (see Chapter 6.7.1, "Visualisation", page 68).
Note:
The building-side piping should be designed according to the Tichelmann
Principle in order to maintain a hydraulically balanced system.
If this is not the case, the flow volume of each Liquid Cooling Package Plus
must be assured by using a flow quantity regulator.
Ideally, the Liquid Cooling Package Plus is connected to the cooling water
system using a water/water heat exchanger.
Advantage:
• Reduction of water volumes in the secondary circuit,
• Setting of a defined water quality,
• Setting of a defined input temperature and
• Setting of a defined volumetric flow.
