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.
