2.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)
