TROUBLE SHOOTING AND MAINTENANCE
Temperature Control: Factory set for 50°F water under normal conditions.
To adjust water temperature, turn screw on Item No. 7 clockwise for colder,
counter clockwise for warmer.
Ventilation: Cabinet louvers and condenser fins should be periodically
cleaned with a brush, air hose, or vacuum cleaner. Excess dirt or poor
ventilation can cause no cold water and compressor cycling on the overload
protector.
Lubrication: Motors are lifetime lubricated.
Actuation of Quick Connect Water Fittings: Cooler is provided with lead-
free plug which utilizes an o-ring seal. To remove plug from cooler, relieve
water pressure, pull the collar towards the fitting and pull the fitting off the
tube. To install plug, push fitting straight onto tubing until it reaches a
positive stop, approximately 3/4”.
