Positioning the units

CoolServe can be installed in horizontal as well as in vertical position.
It is absolutely necessary to avoid air recirculation between cold and warn side, therefore a
separation in the rack is to include. Make sure an air direction "front to back" at both installation
positions.
The condensate connection must be in both installation positions at the bottom.
Horizontal Position:
Basically th unit can be fitted in every HU of a 19" rack, from safety reasons be recommend to
install the unit at the lowest HU level
Vertical Position:
CoolServe can also be fitted in vertical position beside the 19" server level.

Chilled water connection

If the heat exchanger is connected to the chilled water network using threaded fittings,
the pipe fitting must be supported on tightening.
Prior to commissioning the server cabinet, the pipe connections
should be checked for leaks.
Preparing heat exchanger for initial commissioning:
- Check the mechanical installation and the supply pipe connection.
Note: The use of the optional connecting set makes the bleeding more comfortable as well as
it is possible to check and adjust the chilled water flow rate.
- If necessary, re-tighten threaded fittings.
- After an extended period without use, and particularly in case of risk of
frost, the heat exchanger and the supply pipe are to be completely drained.
Drain completely by blowing out with compressed air and remove all bleed
and drain plugs.
