are satisfactory.
Cooling water temperature is too
high Check and adjust as necessary.
Cooling radiator is dirty Clean to ensure adequate air flow across fins.
Low fluid level Add fluid to required level on reservoir
Operating pressure is too high Rotary screw pumps are designed to operate in the 10" to
29.9" HgV range. Any operating pressure over 10" may
cause the pump to overheat.
Excessive pressure in exhaust line Clear restrictions in exhaust line to ensure atmospheric
pressure at discharge.
FREQUENT AIR/FLUID SEPARATOR CLOGGING

Incorrect fluid separator element Use genuine Quincy replacement elements only
Extreme operating conditions such
as high vacuum pump discharge
temperatures, high ambient
temperature and high reservoir
pressure Operate vacuum pump at recommended reservoir pressure
and air discharge temperature
Fluid contamination Change fluid. Service inlet filter element and fluid filter
promptly in accordance with the recommended maintenance
schedule.
Too high fluid level in reservoir Bring fluid level to recommended level by draining the
reservoir. Use the fluid level gauge as a guide.
