TROUBLE SHOOTING & MAINTENANCE
Temperature Control: Factory set at 45°F (± 2°) under normal conditions. For colder
water, adjust screw on item no. 10 in clockwise direction.
Ventilation: Cabinet louvers and condenser fins should be periodically cleaned with
brush, air hose or vacuum cleaner. Excess dirt or poor ventilation can cause no cold
water and compressor cycling on the compressor overload protector.
Lubrication: Motors are lifetime lubricated.
Actuation of Quick Connect Water Fittings: Cooler is provided with lead-free
connectors which utilize an o-ring seal. To remove tubing from the fittings, relieve
water pressure, push in on gray collar while pulling on the tubing. To insert tubing,
push tube straight into fitting until it reaches a positive stop, approximately 3/4.
