2.1Proper Application

The XDK is a water-cooled enclosure and is intended for removing heat from electronic equipment inside the cabinet. The cooling system in the cabinet is thermally independent of the room air. Water is used to cool equipment installed in the XDK. No additional cooling of the server room is required.

NOTE

Under certain conditions, a small amount of heat, (approximately 0.5kW), can escape into the room.

! CAUTION

Risk of improper operation. Can cause equipment damage. For reliable function of the XDK, cold water must be available in the correct amount, and at the correct temperature and pressure. Observe water quality specified in VGB-R 455 P. (see 8.0 - Water Purity Requirements ).
