1. Before connecting power supply and assembling bottom cover to water cooler, but after thoroughly flushing the supply
line and connecting it to the fixture, turn on building water supply and check all connections for leaks.
2. Air within the water cooler system or the structure supply piping will cause an irregular bubbler outlet stream until
purged out by incoming water. Covering the bubbler with a clean cup (or similar object) is recommended when first
activating water cooler to prevent excessive splashing. Depress the pushbutton until steady water stream is achieved.
7. Assemble Bottom Cover to Water Cooler with screws furnished.
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.
5. With power still
NOT
connected, carefully manually rotate cooling fan to insure proper clearance and free fan action.
1. Adjustments
a. Cartridge – The water flow can be adjusted through the pushbutton using a straight 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.
3. If water flow requires adjustment, insert a slotted narrow blade screwdriver through the hole centered on the
pushbutton to the flow regulator. Turning clockwise will increase flow and turning counterclockwise will decrease flow.
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. Recheck all Water and Drain connections with water flowing through system.
T
ROUBLE 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.
START UP:
6. Plug Water Cooler in to Electrical Outlet and make sure unit begins to function.
IMPORTANT : ASSUREZ-VOUS QUE LA FONTAINE D'EAU POTABLE RÉFRIGÉRÉE SOIT
