HP Modular Cooling System Site Preparation Guide

The HP MCS is provided with 1-¼-inch diameter flexible inlet and outlet chilled water hoses, each
with an overall length of approximately 44 inches (1100 mm) and consisting of about 34 inches
(864 mm) of flexible hose terminated at each end with fittings (Figure 11).
Figure 11. HP MCS Outlet Water Hose.
CAUTION:
It is essential that the proper cabinet and facility cool water inlet and
warm water outlet hoses are connected properly. A check valve prevents
reverse flow.
HP recommends using the HP Water Hook-up Option Kit (available at www.hp.com) for connecting
the HP MCS to the facility chilled water system. Each kit (Figure 12) includes the fittings required for
connecting the facility supply and return lines to the inlet and outlet hoses of one HP MCS unit. The
water hook up kit should be install prior to HP MCS installation, and includes plugs to temporarily
protect the supply and return lines from debris until the HP MCS is installed and connected.
