NOTICE
A172.8-UG-BFS SERIES REFRIGERATED BI-LEVEL WALL MOUNTED WATER COOLER
NOTE: there are no mounting changes to be made for A172-UG-VR-BFS and A172-UG-SO-BFS models.
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.

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.
7. Assemble Bottom Cover to Water Cooler with screws furnished.
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.
5. With power still NOT connected, carefully manually rotate cooling fan to insure proper clearance and free fan action.
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.
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.
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. Recheck all Water and Drain connections with water flowing through system.
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.
START UP:
6. Plug Water Cooler in to Electrical Outlet and make sure unit begins to function.

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.
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.
4. Do NOT use harsh chemicals, abrasive or petroleum based cleaners. Use of these will void the Acorn warranty.
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.
NOTE: STRAINER SCREEN MUST BE IN PLACE FOR WATER TO FLOW.
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. Check flow adjustment. See start up note #3.
g. 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.
7. Water Drip Or Will Not Shut Off:
a. Remove Pushbutton Adjust flow regulator to the highest setting using a
flat head screwdriver and turning clockwise. Check if water drip continues, if it is no longer
dripping turn screwdriver counter-clockwise until you have desired flow rate. Assure that
retaining nut is tighten to valve assembly, 25 in-lb torque is required. If issue still continues after
adjusting flow and tightening retainer nut, replacement of the flow regulator cartridge will be
required.
1. Motors have lifetime lubrication and do not require scheduled maintenance.
CLEANING & MAINTENANCE GUIDE:
2. Excess dirt or poor ventilation will cause the compress` more frequently.
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.
3. Periodically remove access panels and clean out in-line strainer.
