IMPORTANT

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.

ROUGHING-IN AND DIMENSIONAL DRAWING

7. Assemble p-traps 3 to drain adapters 4 on each unit.

8. Make-up 1-1/4” outer diameter waste connections.

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 .

10. Reassemble access panels 1 to units with screws previously removed.

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.

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.

4. Recheck all water connections with water flowing through system.

5. Provide power to water chiller and make sure unit begins to function.

6. Assemble louvered bottom trim panel with screws provided to brackets on either side of wall

mounting frame.

TROUBLE SHOOTING:
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

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.

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 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. 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 chiller 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. 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 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.
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.

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.
b. Replace valve cartridge.

CLEANING & MAINTENANCE GUIDE:

1. Motors have lifetime lubrication and do not require scheduled maintenance.

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.

3. Periodically remove fountain top and clean out in-line strainer.

4. Do NOT use harsh chemicals, abrasive or petroleum based cleaners. Use of these will void the

Acorn Engineering warranty.

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.
