CONDITIONS	QUINCY SERVICE TECHNICIAN.


Frequent Fluid Filter Clogging:

INCORRECT FLUID FILTER	USE GENUINE QUINCY REPLACEMENT FILTERS ONLY.
SYSTEM CONTAMINATION	CLEAN SYSTEM OF ALL DIRT, CORROSION AND VARNISH.


High Discharge Air Temperature:

EXCESSIVE AMBIENT TEMPERATURES	MAXIMUM AMBIENT FOR PROPER OPERATION IS LISTED IN DATA
	SHEET. VENTILATE ROOM OR RELOCATE COMPRESSOR.
INADEQUATE COOLANT FLOW THROUGH	CLEAN COOLER(S). CHECK WATER SYSTEM FOR POSSIBLE
COOLER(S) (WATER-COOLED)	RESTRICTIONS.
INADEQUATE CIRCULATION OF COOLING	CHECK THE COOLER TO ASSURE THERE ARE NO RESTRICTIONS TO
AIR (AIR-COOLED)	FREE CIRCULATION OF COOLING AIR.
