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

provide 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

filters 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 (2413kPa)

is available as an option.
