Always use new gaskets when servicing the valves. Check to be sure the
reed valves are seated perfectly flat against the sealing surface around each
port. Damaged or improperly seating valves will cause lower than normal
discharge pressure, excessive heat, and carbon buildup.
•Lubrication
Quincy Climate Control Series compressor units are shipped with
Quin-Cip (ISO 68) lubricant in the crankcase. Basic compressors sold
as replacements may be shipped with Quin-Cip (ISO 68) in a separate con-
tainer to avoid spillage. Replace the break-in lubricant after 100 hours
of operation with Quin- Cip lubricant!
Quin-Cip lubricant has proven under extensive testing to min imize friction
and wear, limit lubricant carryover, and reduce carbon and varnish deposits.
It will support the performance characteristics and life designed into all
Quincy compressors and is highly rec ommended. Refer to the charts below to
determine the correct amount of lubricant and viscosity to use for your model
and applica tion.
Approximate Crankcase Lubricant Capacities
Splash Lubricated Model Lubricant Capacity
QTS3QCB (1/2, 3/4 h.p.) *20 oz. (590 ml.)
QTS3QCB (1 & 1-1/2 h.p.) **12 oz. (354 ml.)
QTS5QCB 39 oz. (1140 ml.)
QT5QCB & QT7QCB 1 qt. & 20 oz. (1.3 lit.)
QT10QCB (R.C. 200C) 2.5 qts. (2.37 lit.)
QT15QCB 3 qts. & 24 oz. (3.55 lit.)
*A shorter (white) dipstick and higher lubricant level is required for QTS3QCB compressors
run at 350 RPM to 425 RPM.
**A standard (black) dipstick and normal lubricant level is required for QTS3QCB compressors
run at 426 RPM to 600 RPM.
Pressure Lubricated Model Lubricant Capacity
210QRB 26 oz. (770 ml.)
216QRB, 310QRB & 325QRB 1 qt. & 22 oz. (1.6 lit.)
340QRB & 350QRB 4 qts. & 30 oz. (4.7 lit.)
390QRB 9 qts. & 22 oz. (9.2 lit.)
5120QRB 9 qts. & 30 oz. (9.4 lit.)
Pressure lubricated models are designed to be operated at 18 to 20 PSIG
lubricant pressure (at rated speed and operating temperature). The oil pres-
sure relief valve on the oil pump can be adjusted. To do this, loosen the locknut
seated against the side of the oil pump hous ing. Turn the adjusting screw
clockwise to increase; counter clockwise to decrease the lubricant pres sure.
Re-tighten the locknut.
