WATER CHILLER IS DISCONNECTED FROM THE ELECTRICAL SUPPLY AND THE
7. Assemble p-traps 3 to drain adapters 4 on each unit.
9. After thoroughly flushing the 3/8” outer diameter supply line, connect water supply to in-wall chiller
and provide connection from chiller to each drinking fountain in-line strainer 5 .
4. Recheck all water connections with water flowing through system.
START UP:
8. Make-up 1-1/4” outer diameter waste connections.
10. Reassemble access panels 1 to units with screws previously removed.
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.
3. If water flow requires adjustment, insert a slotted narrow blade screwdriver in the hole centered on
the underside of the fixture in the knee clearance area up to the flow regulator. Turning clockwise
will increase flow and turning counterclockwise will decrease flow.
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.
6. Assemble louvered bottom trim panel with screws provided to brackets on either side of wall
mounting frame.
5. Provide power to water chiller and make sure unit begins to function.
TROUBLE SHOOTING:
IMPORTANT: BEFORE MAKING ANY OF THE REPAIRS LISTED, MAKE SURE THE
WATER SUPPLY VALVE IS SHUT OFF.
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 supply for power and correct voltage. The incoming voltage must be within
10% of the rated voltage on the serial nameplate.
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.
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.
1. Adjustments
c. Check for loose wires within the compressor box. The incoming power leads must be connected
to the overload and relay.
