Water-Cooled Models—Self-Contained Compressor

4.0 WATER-COOLED MODELS—SELF-CONTAINED COMPRESSOR

4.1 Piping Considerations

Manual shutoff valves should be installed at the supply and return lines of each unit. This will pro-

vide for routine maintenance or emergency isolation of the unit.

When the water source for the condenser is of poor quality, it is good practice to provide cleanable fil-

ters in the supply line. These filters will trap the particles in the water supply and extend the service

life of the water-cooled condenser.

To provide for the emergency of water leaks and the consequences of sub-floor flooding, floor drains

should be provided with wet traps or a water detection system such as a Liebert Liqui-tect

™

sensor

that is installed near the base of the unit or below the elevated floor.

4.2 Condenser

The condenser is designed to operate in conjunction with either a cooling tower or city water. The

maximum water pressure is 150 psig (1034 kPa). A high pressure system rated at 350 psig (2413 kPa)

is available as an option.
