Operating and Maintenance Instructions – Installation checklist
Rittal Liquid Cooling Package Plus
Was the water prepared/
treated with the appropriate
additives?
In addition to our recommendations regarding water quality, we recommend
that the water be enriched with corrosion inhibitor and/or antifreeze. Also, a
treatment to prevent algae and biofilms may be expedient in some cases.
Are unused height units in the
bayed server enclosures
sealed through vertical
blanking plates, and are the
side vertical foam strips
installed?
In order to prevent undesired air short circuits and circulation patterns inside
the server enclosure, all unused height units of the 482.6 mm (19") level should
be closed off with blanking plates. Thus, the air will only enter the rear side of
the server enclosure through the server itself, where it is drawn off by the Liquid
Cooling Package. The blanking plates are available in various heights, e.g. Mo-
del No. SK 1931.200 for one height unit. The vertical foam sealing strips, which
are installed on the side in the server enclosure, ensure that the cooled air does
not flow on the sides, past the 482.6 mm (19") level. Sealing strips are available
for 2 applications and 2 enclosure widths. The respective model numbers are
found in Chapter 13, "Accessories" in the operating and maintenance instruc-
tions of your Liquid Cooling Package
Are all electrical, water, and
power connections correctly
made?
Before water is admitted, and, ideally before the ball valves are opened, be
sure to check that all connections are properly made. Pay special attention to
check that all quick release fasteners are fully snapped into place.
Is the TS/PS server enclosure
equipped with the appropriate
door?
Both the Liquid Cooling Package Standard and the Liquid Cooling Package
Plus function with a sealed air circuit. Thus, the cooled server enclosure must
largely be hermetically sealed and equipped with unperforated steel or glass
doors on the front and rear sides.
Exception when using the Liquid Cooling Package Extend:
The front of the server enclosure must, in this case, be fully air permeable.
After admitting cold water:
Are all parts and connections
water tight?
Please check to be sure that all parts and connections which carry water are
water tight. The Liquid Cooling Package is subject to an individual, comprehen-
sive factory test, which also includes checking for leaks. This additional check
serves to locate problems, such as possible transport damage, and to prevent
greater damage.
Venting of the Liquid Cooling
Package Plus
The Liquid Cooling Package Plus has an automatic vent. This has been closed
in the factory and must be opened for venting purposes during initial startup.
Close the vent again after startup. To gain access to the vent, the top fan must
be removed.
