INSTALL WATER TO OIL COOLER ON FA COMPRE- SORS Ð On FA compressors, water must be piped to the oil cooler heat exchanger (located under the suction pipe to the compressor). The water supply may be either city water or chilled water. Pipe city water to an open sight drain. Chilled water enters via the cooling entering water intake (Fig. 15).

City water must be clean and noncorrosive. Water side erosion or corrosion of the oil cooler coil may lead to extensive machine damage not covered by the standard warranty.

If water from the machine chilled water circuit is used for oil cooling, it should enter the oil cooler from the entering water line of the machine cooler. Water leaving the oil cooler should connect to the leaving water line of the machine cooler at a point downstream from the chilled water sensor, so that oil cooler leaving water temperature does not affect the sen- sor readings.

Locate the oil cooler leaving water connection at some distance from any water temperature indicators. On single- pass machines, water leaving the oil cooler should be con- nected into the suction side of the chilled water pump so that adequate pressure drop is assured for oil cooling.

The nominal conditions for oil cooler water ¯ow are:

Flow rate . . . . . . . . . . . . . . . . . . . . . . . 30 gpm (1.9 L/s) Leaving temperature . . . . . . . . 85 to 100 F (29 to 38 C) Pressure drop at oil cooler . . . . . . . 7.25 psid (50 kPad) Max differential pressure across closed

solenoid valve . . . . . . . . . . . . . . 150 psid (1034 kPad)

The oil cooler connections are 11¤4 in. FPT.
