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. Check for loose wires within the compressor box. The incoming power leads must be connected
to the overload and relay.
2. Air within the drinking fountain 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 drinking fountain to prevent excessive splashing.
Depress front push pad until steady water stream is achieved.
a. Check the electrical supply for power and correct voltage. The incoming voltage must be within
10% of the rated voltage on the serial nameplate.
9. After thoroughly flushing the 3/8” outer diameter supply line, connect water supply to in-wall chiller
and provide connection from chiller to drinking fountain 1/4” x 3/8” O.D. Push-In 8 .
5. Provide power to water chiller and make sure unit begins to function.
IMPORTANT: BEFORE MAKING ANY OF THE REPAIRS LISTED, MAKE SURE THE WATER
CHILLER IS DISCONNECTED FROM THE ELECTRICAL SUPPLY AND THE WATER SUPPLY
VALVE IS SHUT OFF.
1. Adjustments:
10. Place drain gasket 9 on drain adapter 6 . Reconnect bubbler tube 3 . Reassemble top
1 to unit by engaging back clip and securing with screw 2 .
START UP:
1. Before connecting power supply, but after thoroughly flushing the supply line and connecting it to
the cooler, turn on building water supply and check all connections for leaks.
4. Recheck all water connections with water flowing through system.
TROUBLE SHOOTING:
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.
6. Assemble louvered bottom trim panel with screws provided to brackets on either side of wall
mounting frame.
7. Assemble P-Trap 5 to drain adapter 6 and then assemble to unit with Phillips screws 7 .
c. Bubbler Stream - Bubble can be rotated slightly to direct the stream backwards or forwards.
Adjust the stream to minimize splashing. Splashing can occur from bubble stream if the unit is
not level. Shim lower mounting point, if necessary, to level chiller.
2. Compressor Does Not Run:
8. Make-up 1-1/4” outer diameter waste connection.
3. If water flow requires adjustment, insert a slotted narrow blade screwdriver in the hole centered on
the pushbutton of the fixture to the flow regulator. Turning clockwise will increase flow and turning
counterclockwise will decrease flow.
b. 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. Disconnect electrical supply to the
water chiller 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.
