HP Modular Cooling System manual Description Quantity

HP recommends the HP mc-Series 5042 Rack Water Hook-up Option Kit BW971A (available on the HP website at http://www.hp.com) for connecting the MCS 5042 to a facility chilled water system. Each kit (Figure 21) includes the hoses and accessories required for connecting the facility supply and return lines to the main inlet and outlet connections of an MCS 5042 unit and must be installed prior to the delivery of an MCS 5042.

*Not drawn to scale. The actual length of the main hose is approximately 3.5 m (11.5 ft).

Caution:

You must properly connect the cabinet and facility cool water inlet and warm water outlet hoses. The MCS 5042 does include a check valve to prevent the reverse flow of coolant.

The MCS 5042 has the connecting fittings inside the unit, approximately 600 mm (24 inches) above the floor on the rear side. It allows the main coolant hoses to be routed either down through the cutouts in a raised floor (HP recommended) or up through openings in the top of the cabinet and above the unit or through the back of the cabinet and above the floor as shown in Figure 22. The left (blue) hose designates the chilled water supplied to the MCS 5042 and the right (red) hose is the warm water exiting from the MCS 5042.
