remove all foreign matter before being connected to cooler. If
flushing does not remove all particles, a water strainer should be
installed in supply line. This cooler is manufactured in such a manner
that it does not in any way cause taste, odor, color or sediment
problems. If a taste, odor or sediment problem is prevalent, try

TROUBLE SHOOTING & MAINTENANCE
Temperature Control: Factory set at 50°F (± 5°) under normal
conditions. For colder water, adjust screw on item no. 12 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.

with lead-free connectors which utilize an o-ring seal. To remove
tubing from the fittings, relieve water pressure, push in on gray
