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

used for the drain connection.
2. Provide 4” minimum clear space on fixture sides to allow for proper ventilation through cabinet
louvers.
3. Water supply is 3/8” Outside Diameter copper tube. Waste is 1-1/4” Outside Diameter.
4. Completely flush supply lines of all foreign debris before connecting to fixture. Water cooler
designed to not affect taste, odor, color, or sediment. Optional water filter (Wf1) is available should
any of these problems arise from the water supply.
5. Do NOT solder copper tube when inserted into the coupler as damage to the o-ring will result.
6. All burrs must be removed from outside of cut tubes before inserting into coupler or other
components.
7. Power supply must be identical in voltage, cycle and phase to that specified on the cooler data
plate. Electrical outlet and furnished power cord with plug must be used to supply power to
fixture. Do NOT wire compressor directly to the power supply.
8. This unit must be grounded per the requirements of applicable electrical codes.
9. WARNING: Warranty is voided if installation is not made following current Acorn Aqua
installation instructions and if components are assembled to the fixture that is not approved by
Acorn Aqua.
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:
Choose configuration; Remove and reinstall filler plate, item 30 , reverse drain assembly
if required for alternate mounting configuration.
1. Mount hanger bracket to wall horizontally level as shown in Roughing-In and Dimensional Drawing.
Note: Adjust height of bracket if bubbler outlet height is required to vary from that shown.
WARNING: Hanger Bracket MUST be securely anchored to wall with fasteners sufficient to support
3 times the weight of cooler. If wall can not provide adequate support, order and install optional
fixture support carrier.
2. Remove the bottom cover from the water cooler and set aside in a safe place. Save the screws
in a secure location for re-use in later stages of installation.
3.
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 the pushbutton until steady water stream is achieved.
3. If water flow requires adjustment, insert a slotted narrow blade screwdriver through the hole
centered on the pushbutton 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.
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.
Hang the water coolers on the hanger brackets ensuring the bracket tabs engage AND seat in the
slots in the back of the water coolers. Note: Hanging of refrigerated unit first is recommended since
it is the heavier of the two. Verify water coolers are level, left to right AND front to back from bottom
of unit.
Caution: The bubbler stream may be adversely affected if units are not square and level. Bottom of
units and louvers should be used as reference to verify unit is square and plumb.
4. Anchor the water coolers to the wall at the lower mounting points in each back panel. Shim lower
mounting points to level unit if necessary.
5. Outlet tube from evaporator has an in-line tee with a tube going to refrigerated unit's valve and the
"TEE" not connected. Connect the loose supply tube from refrigerated unit to the "TEE".
6. Thoroughly flush the 3/8” O.D. supply line and then connect water cooler to water supply angle
stop valve (by others) with supplied 3/8” O.D. copper tube.
7. Use supplied flexible hose and clamps to connect waste tailpiece from upper unit to waste tailpiece
of lower unit and then make up 1-1/4” O.D. p-trap waste connection. Waste p-trap by others.

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 through the pushbutton using a straight 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.
c. Bubbler Stream – Bubbler can be rotated slightly to direct the stream backwards or forwards. Adjust
the stream to minimize splashing. Splashing may occur from bubbler stream if the unit is not level.
Shim lower mounting points, if necessary, to level cooler.
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.
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.
