Plumbing considerations

A number of plumbing factors must be considered when installing the MCS 5042:

•(Highly recommended) Installing water shut off valves to enable infrastructure system flushing for the inlet and outlet of each MCS 5042

•Flow rate and pressure capacity of chilled water plant input to the design of the facility feed line and dedicated water loop pipe diameters

•Material compatibility within piping system to minimize the potential for electrochemical corrosion and must be corrosion-resistant

•Minimization of elbows and other restrictions that increase flow resistance

•Insulation of piping to minimize risk of condensation and reduce incidental heating of supplied chilled water

•Availability of a floor drain or reclamation system to capture system condensation

•Structural securing of piping to support weight of distribution network filled with water

•Water quality management, including particulate filtration, treatment, and flushing provisions, with isolation valves for service requirements

•Availability and access to a data center leak detection system to monitor the infrastructure system for leaks

•Air vents installed at the highest point in the pipe system (Each MCS 5042 has an air vent, but additional vents in the supply piping system must be considered.)
