5.7 Chilled Water Connections
5.7.1 Strainer
Install a 20-40 mesh strainer on the chilled water supply to the Liebert DCP. The strainer is required to
prevent particles in the chilled water from entering the Liebert DCP’s heat exchanger. The strainer must
be no more than 10 feet (3m) from the Liebert DCP.
5.7.2 Service Valves
Install 1" ball valves (field-supplied/field-installed) on the supply and return lines to the Liebert DCD to
allow service on the unit without shutting down the entire system.
5.7.3 Balancing Valves
Install balancing valves (circuit setters) in the supply line to the unit. Refer to Capacity Performance on
page52 for the proper flow rate required to achieve the site-specific capacity
NOTICE
Risk of improper storage. Can cause frozen or damaged coil and piping, resulting in fluid leaks, equipment
damage and serious building damage.
The heat exchanger and the piping must be cleared of any water before the unit is stored. Compressed
air can be used to remove the water. Remove all the vents and the screws before storing. Vertiv™
recommends storing of the module indoors protected from freezing, dampness and contact damage.
