SEC I CONT · SEC. II SEC. III
Problem - Compressor runs, but will not refrigerate.
Condition - The compressor and fan motor runs with little
or no refrigeration effect.
Solution - Clogged Condenser
Air cooled condensers must be kept free of lint, dust,
or other material for proper operation. A dirty
condenser restricts the air flow, thereby reducing the
capacity of the cooler.
Solution - Plumbing
connections. Water supply must be connected to
the "Water In" connection.
Solution - Compressor
With the compressor running continuously, will not
cycle, or with no refrigeration effect, the compressor
or other refrigeration component may be defective.
The water cooler in warranty should be repaired at a
factory authorized repair station.
SECTION II - TROUBLE SHOOTING OF THE WATER SYSTEM
The following is a list of possible conditions which may
be encountered in trouble shooting the water system.
1 - Problem - Restricted or No Water Flow
Solution A - Water Supply Valve
Check water supply line valve or valves. Be sure
they are fully open.
Solution B - Water Pressure
Check water line pressure. It should be between 20
and 80 PSI. If above 80 PSI a pressure regulator
with a setting of 40 PSI should be installed.
Solution C - Plumbing Connections
Check for proper plumbing connections to cooler.
The "Remote" connection must never be connected
to a waste line.
Solution D - Water Line Strainer
installed. Reverse flush the cooling unit, if line
strainer is not used, by transferring the water inlet
line to the "Remote" connection and allowing the
reverse flow of water to emerge from the "Water In"
connection. After flushing, return piping to original
Solution E - Water Regulating Valve Strainer
Clean or replace the water regulating valve strainer
screen located in the base of the valve. The entire
assembly must be removed to gain access to this
Solution F- Water Regulating Valve Adjustment
Water regulating valves of the adjustable type have
a replaceable cartridge. In the top of this cartridge
there is a slotted adjusting screw. Turning the
adjusting screw clockwise increases the water
stream, counter-clockwise reduces the water stream.
removing the cartridge.
Self Adjusting water regulating valves should follow
Solutions "B" and "'D".
Solution G -Freeze Up
Open "Remote" connection, with water supply valve
fully open. No flow indicates the cooling unit is
frozen. Disconnect the electrical supply from cooler
and allow the unit to remain in a warm ambient until
it thaws. Recheck refrigeration system and related
controls. Correct any malfunction before energizing
the cooler. Check the cooling unit for any rupture or
leaks. After draining the cooling unit, repair any
break found by soldering or replacement.
Problem - Continuous Water Flow
Solution A - Valve Binding
Check water regulating valve and linkage for free
operation. Lubricate all binding parts with a
tasteless, odorless light grease.
Solution B - Specific Instructions
Specific instructions regarding the water regulating
valve can be had on request. Model, style, and
serial number, found on Model Plate, should be
furnished to fulfil this request.
3 - Problem - Improper Drainage.
Solution A -Drain Strainer
Inspect the strainer attached to cabinet top. Waste
may collect at this point and stop. the flow.
Solution B - Cooler Drain Line
Remove the drain strainer from the cabinet top and
probe the drain line for possible blockage.
Solution C - Building Drain
Remove the drain connection from water cooler.
Observe the cabinet top. If water drains with piping
removed, the building drain line is plugged or
SECTION III - ADJUSTMENT
Most controlling thermostats are provided with an
adjustment between the temperature at 470°F. and
55F. Turning the adjustment clockwise lowers drinking
water temperature. Thermostats are factory adjusted to
deliver 50°F. water temperature.
