Operating conditions

Correct use
The unit is a server cabinet cooling device and is only used for the
removal of heat from server cabinets to protect temperature
sensitive components. The cooling system in the cabinet is thermally
independent of the room air. Total heat load of the installed equipment is
taken out of the room using the chilled water circuit. Note: Under special conditions a very
small amount can dissipate to the room (approx. 05, kW)
For reliable function of the CoolTherm, chilled water
must be available in the correct amount, and at the correct
temperature and pressure. Observe water quality as per
VGB-R 455 P. (see Appendix)
