4.0 WATER-COOLED MODELS—SELF-CONTAINED COMPRESSORWater-Cooled Models—Self-Contained Compressor4.1 Piping ConsiderationsManual shutoff valves should be installed at the supply and return lines of each unit. This willprovide 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 cleanablefilters in the supply line. These filters will trap the particles in the water supply and extend theservice life of the water-cooled condenser.To provide for the emergency of water leaks and the consequences of sub-floor flooding, floor drainsshould be provided with wet traps or a water detection system such as a Liebert Liqui-tect sensorthat is installed near the base of the unit or below the elevated floor.4.2 CondenserThe condenser is designed to operate in conjunction with either a cooling tower or city water. Themaximum water pressure is 150 psig (1034 kPa). A high pressure system rated at 350 psig (2413 kPa)is available as an option.35
