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
strainer is furnished with this water cooler to meet this requirement.
ROUGHING-IN AND DIMENSIONAL DRAWING
Prior to roughing consult with local, state, and federal codes for proper mounting height.

10. Fixture operates within water pressure range of 20 to 105 psig. Acorn Aqua will not warranty
fixtures damaged when connected to supply lines with flow pressure lower than 20 psig or
higher than 105 psig. A pressure regulator must be furnished by others on supply line if inlet
pressure is greater than 105 psig.
11. Due to cold waste water, Acorn Aqua recommends that p-trap supplied by installer be insulated
to prevent excessive condensation.
12. Per UPC 609.10- All building water supply systems in which quick acting valves are installed
shall be provided with devices to absorb the hammer caused by high pressure resulting from the
quick closing of the valve. These pressure-absorbing devices shall be approved mechanical
devices. Water pressure-absorbing devices will be installed as close as possible to the quick
closing valve.
INSTALLATION:
START UP:
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 a side or front push bar 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 and drain connections with water flowing through system.
1.Provide rough-ins as shown in Roughing-In and Dimensional Drawing.
2. Anchor water cooler to wall through anchor clips on the bottom of the base.
3. Remove the front panel from the water cooler by taking out the screws on each side at the
bottom front, press the panel sides together at the bottom so that front panel clips disengage
from the housing sides and carefully pull forward and down. Set panel aside in a safe place
where it will not be damaged.
5. After thoroughly flushing the 3/8” o.d. supply line, connect water supply to water cooler .
6. Make up 1-1/4” o.d. p-trap waste connection.

5. With power still NOT connected, carefully manually rotate cooling fan to insure proper clearance
and free fan action.
6. Plug water cooler in to electrical outlet and make sure unit begins to function.
7. Assemble bottom cover to water cooler with screws furnished.
TROUBLE 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.
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 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.
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. 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. Make sure the water cooler is correctly mounted to the wall. Absence of the two lower
mounting bolts may cause excess noise and vibration.
c. 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 bubbler tubing.
L1001054 Revised: 07/27/10

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 cooler 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 cooler needs to be checked by a qualified technician.
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 access panels and clean out in-line strainer.
4. Do NOT use harsh chemicals, abrasive or petroleum based cleaners. Use of these will void the
Acorn Aqua 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.
