PWC-450 Cooler
1. Introduction
The PWC-450 line of point of use counter-top coolers are designed to give years of reliable
Service. The cooler has a single spigot that dispenses water at 2 different temperature
levels – hot and cold temperature water. The main (cold-temp) tank holds 1 gallon of water
and is constructed of stainless steel. The cold tank can be accessed for cleaning by removing the
cooler main top cover (see section 4).
The hot tank is made of stainless steel and holds 1/2 gallon of hot water. It is important not
to turn on the hot tank when there is no water in it as this will damage the heating element.
The compressor is a sealed unit and is not serviceable in the field. The compressor can be
replaced by a qualified refrigeration technician with proper tools and equipment.
Please consult the factory if the compressor needs servicing.
CAUTION: If the compressor has been stopped by switching it off or unplugging power,
WAIT 10 MINUTES before turning the compressor on again. The compressor may stall
and burnout if powered back on without waiting.
Electrical power is required for the cooler to fill the cooler with water. CAUTION: If hardness
is higher than 7 grains, softening of the feed water is recommended or another option is to
install a “phosphate” filter to the filter system.
