TROUBLE SHOOTING:
IMPORTANT: BEFORE MAKING ANY OF THE REPAIRS LISTED, MAKE SURE THE WATER
COOLER IS DISCONNECTED FROM THE ELECTRICAL SUPPLY AND THE WATER SUPPLY
VALVE IS SHUT OFF.
1. Adjustments:
a. Cartridge – The water flow can be adjusted using a slotted narrow blade screwdriver and
turning clockwise to increase flow and counterclockwise to decrease flow.
b. Cold Water Thermostat – The water temperature can be adjusted using a slotted
screwdriver and turning clockwise to make colder and counterclockwise to make warmer.
c. Bubbler Stream – Bubbler can be rotated slightly to direct the stream backwards or
forwards. Adjust the stream to minimize splashing. Splashing may occur from bubbler
stream if the unit is not level. Shim lower mounting points, if necessary, to level cooler.
2. Compressor Does Not Run
a. Check the power supply cord.
b. Check the electrical receptacle for power and correct voltage. The incoming voltage must be
within 10% of the rated voltage on the serial nameplate.
c. The cold thermostat is accessible by removing the bottom access cover. If the cold
thermostat capillary bulb loses its charge or becomes kinked it will fail in the open position
causing a disruption of power to the compressor. Unplug the water cooler and using an
ohm meter check for continuity across the two electrical terminals on the thermostat. Install a
new thermostat if there is no continuity.
d. Check for loose wires within the compressor box. The incoming power leads must be
connected to the overload and relay.
e. If all components check positive for continuity then test the wiring harness plug for
continuity to see if there is a broken wire within the wiring harness insulation.
3. Compressor Runs – Water Is Warm
a. The most common cause for a water cooler to run without producing cold water is a
loss of refrigerant. The water cooler must be taken to a certified refrigerant technician
for repairs.
b. Make sure the condenser fan motor is operative. The fan blade must turn freely to help
remove the heat of compression.
c. An incorrect refrigerant charge, restriction or defective compressor (not pumping) will
also cause the compressor to run without producing cold water. All these signs indicate
a problem within the refrigeration system and the water cooler must be checked by an
authorized service company.
4. Compressor Cycling On Overload Protector
a. A dirty condenser or a blocked fan will cause a high head pressure and frequent cycling
of the overload protector.
b. Check the incoming voltage to make sure it is within 10% of the serial nameplate rating.
c. A restriction or moisture in the system will also cause intermittent cycling. A certified
refrigeration mechanic should be contacted in this situation.
IMPORTANT : ASSUREZ-VOUS QUE LA FONTAINE D'EAU POTABLE RÉFRIGÉRÉE SOIT
DÉBRANCHÉE DE LA PRISE DE COURANT MURALE ET QUE LE ROBINET D'ALIMENTATION
D'EAU SOIT FRMÉ AVANT D'EFFECTUER LES RÉPARATIONS NÉCESSAIRES.
