CONDENSER WATER PIPING

Piping - Use piping for maximum pass operation,

Fig. 17, when ample water pressure is available.

Use minimum pass operation. Fig. 18, for low

water pressure or when cooling tower is used.

Water Regulating Valve Adjustment - Set shut-off

point at least 10 F below condensing temperature

to be maintained at maximum load, but not above

90 F. Select shut-off point high enough to close

valve when unit is not operating.

LUBRICATION

Compressors are charged with oil at the fac

tory. Oil quantities are given in Table 12.

Maintain oil level at center of sight glass.

When adding oil, use only a dehydrated, wax-

free refrigeration grade oil of suitable viscosity.

Compressors are charged with refrigeration

grade oil (Carrier No. PP36) for evaporator tem

peratures above -45 F. When evaporator tempera

ture is -40 or below, replace oil with Carrier

No. PP33.
