and free fan action.
6. Plug water cooler in to electrical outlet and make sure unit begins to function.
7. Assemble bottom cover to water cooler with screws furnished.
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.
2. Compressor Does Not Run
a. Check the electrical receptacle for power and correct voltage. The incoming voltage
must be within 10% of the rated voltage on the serial nameplate.
b. 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 and ohm meter check for continuity across the two electrical terminals on the
thermostat. Install a new thermostat if there is no continuity.
c. Check for loose wires within the compressor box. The incoming power leads must be
connected to the overload and relay.
d. 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.
d. Change the overload or relay if defective.
5. Noisy Operation
a. Check to make sure the fan blade is rotating freely.
b. Make sure the water cooler is correctly mounted to the wall. Absence of the two lower
mounting bolts may cause excess noise and vibration.
c. Check the compressor mounting to make sure the pins and clips are not rattling. If the
compressor appears to be noisy internally, it must be replaced.
6. Restricted Or No Water Flow
a. Ensure water supply service stop valve is fully open.
b. Verify minimum 20 psig supply line flow pressure.
c. Check for twists or kinks in bubbler tubing.
