PWC-2000 Cooler
1. Introduction
The PWC-2000 line of point of use coolers are designed to give years of reliable service
The cooler has 3 spigots that dispense filtered water at 3 different temperature levels –
room temperature, hot, and cold temperature water. The main (room-temp) tank holds
2.2 gallons of water and is constructed of bacteria resistant plastic. The main tank can be
accessed for servicing the float mechanism and for cleaning by removing the cooler main
top cover and then the room temperature tank cover (see section 4).
The cold tank is made of stainless steel and holds ½ gallon. The tank is not serviceable in the
field as it has the compressor evaporator coils wound tightly around it. If the cold tank
needs service, please call the factory or consult with a local refrigeration specialist.
The hot tank is made of stainless steel and holds ½ gallon. It is important not to turn on the
hot tank when there is no water in it as this will damage the heating element. There are two
types of hot tanks in the PWC-2000 PureWaterCooler. The heating band style utilizes a
heating element that wraps around the outside of the hot tank. This hot tank style does not
have insulation on the tank. This version was produced up until November 2002.
The “heating pipe” style of hot tank is recognized by the foam insulation on the
circumference of the tank. The heating element is inside this sealed tank with the two
electrical connections for the heating element protruding from the bottom of the tank. This
version is available on all PWC-2000 coolers produced after November 2002.
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.
The cooler makes clean water by filtration or the reverse osmosis process. Water enters the back
of the cooler and then passes through the filtration system. A feed water ball valve is located
near the filters and must be turned to the on position to allow the unit to make water. When the
cooler is plugged in, the feed water solenoid valve is activated, allowing clean water to fill the
tanks. When the tanks are full, the float valve in the main tank deactivates the feed water
solenoid valve, and water production is stopped. CAUTION: The carbon filtration versions of
the cooler (PWC-2000F) should not be used with water hardness over 7 grains because of
lime scale build up on the heating element. If hardness is higher than 7 grains, softening of the
water is recommended.

10. Remove/Replace Hot Tank Sensor
There are two thermal sensors on the hot tank. The lower sensor controls the heating
element function and the upper sensor is for high temperature cut out. If the hot tank
Is not working one or both of the sensors may have failed in the open position. To
Check for this condition, unplug the cooler from main power, disconnect one of the
Electrical terminals on the sensor. Using an ohm meter, check for continuity. IF there
Is no continuity, the sensor is bad and must be replaced.

section 4 to gain access to the hot tank.
10.1 The hot tank does not have to be removed
from the cooler to change the sensors
