This fixture is intended to dispense water that has been lowered in temperature, but otherwise remains
unchanged by the materials in the water cooler. It is common for electrical equipment to be grounded
to water lines either within a structure or away from it. Every attempt should be made to prevent this
kind of grounding from generating electrical feedback into the water cooler creating electrolysis.
Electrolysis will cause a metallic taste or cause water metal content to increase.
NOTICE
A dielectric coupling must be used to connect the water cooler to the water supply. A nonmetallic
coupler is furnished with this water cooler to meet this requirement.

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.

3. Compressor Runs – Water Is Warm
2. Excess dirt or poor ventilation will cause the compressor overload protector to turn the compressor
off and it will cycle on and off with no cold water coming out of bubbler. Periodically clean with
vacuum cleaner, air hose or brush the condenser fins and cabinet ventilation louvers. In
environments where dirt and dust is more prevalent, clean more frequently.
a. Ensure water supply service stop valve is fully open.
CLEANING & MAINTENANCE GUIDE:
3. Periodically remove fountain top and clean out in-line strainer.
b. Verify minimum 20 psig supply line flow pressure.
6. Restricted Or No Water Flow
f. The water chiller may also develop a freezing condition in which the water will become frozen
inside the evaporator coil. This indicates a refrigeration problem or thermostat failure in which
case the water chiller needs to be checked by a qualified technician.
1. Motors have lifetime lubrication and do not require scheduled maintenance.
4. Do NOT use harsh chemicals, abrasive or petroleum based cleaners. Use of these will void the
Acorn Engineering warranty.
a. The most common cause for a water chiller to run without producing cold water is a loss of
refrigerant. The water chiller must be taken to a certified refrigerant technician for repairs.
b. Check the incoming voltage to make sure it is within 10% of the serial nameplate rating.
b. Replace valve cartridge.
a. A dirty condenser or a blocked fan will cause a high head pressure and frequent cycling of the
overload protector.
a. Check to make sure the fan blade is rotating freely.
5. Exterior panels can be cleaned using mild household detergents or warm, soapy water. Extra care
must be used cleaning chrome plated items and mirror finished stainless steel. They can scratch
easily and should only be cleaned using a clean, soft cloth and mild soap with water or a mild glass
cleaner.
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 chiller must be checked by an authorized service
company.
5. Noisy Operation
4. Compressor Cycling On Overload Protector
d. Change the overload or relay if defective.
b. 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.
b. Make sure the condenser fan motor is operative. The fan blade must turn freely to help remove
the heat of compression.
c. Check for twists or kinks in outlet tubing.
d. Check the water inlet strainer. Sediment from the main supply can get trapped in the screen
along with installation materials such as pipe dope and flux. The screen should be cleaned and
checked on a regular basis and replace if needed.
e. The cartridge valve located in the water control assembly or bubbler can also become clogged
with foreign material. The cartridge valve can only be replaced and not repaired.
c. A restriction or moisture in the system will also cause intermittent cycling. A certified refrigeration
mechanic should be contacted in this situation.
7. Water Drips Or Will Not Shut Off
a. Open fixture. Loosen nuts holding valve bracket assembly to bottom of fixture but do not
remove. Move complete valve bracket assembly further back from the front push pad and
tighten to lock in place.
