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.

or higher than 105 PSIG. A pressure regulator must be furnished by others on supply line if inlet
pressure is greater than 105 PSIG.
IMPORTANT:
4. Completely flush supply lines of all foreign debris before connecting to fixture. Water cooler is
designed to not cause problems with taste, odor, color, or sediment. Optional water filter (WF1) is
available should any of these problems arise from the water supply.
7. Power supply must be identical in voltage, cycle and phase to that specified on the cooler data
plate. Wire Harness must be used to supply power to Chiller. Do NOT wire compressor directly to
the power supply.
PRIOR TO INSTALLATION
9. WARNING: Warranty is voided if installation is not made following current Murdock Manufacturing

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. Check for loose wires within the compressor box. The incoming power leads must be connected
to the overload and relay.
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.
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.
9. After thoroughly flushing the 3/8” outer diameter supply line, connect water supply to in-wall chiller
and provide connection from chiller to drinking fountain 1/4” x 3/8” O.D. Push-In 8 .
5. Provide power to water chiller and make sure unit begins to function.
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:
10. Place drain gasket 9 on drain adapter 6 . Reconnect bubbler tube 3 . Reassemble top
1 to unit by engaging back clip and securing with screw 2 .
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.
4. Recheck all water connections with water flowing through system.
TROUBLE SHOOTING:
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.
6. Assemble louvered bottom trim panel with screws provided to brackets on either side of wall
mounting frame.
7. Assemble P-Trap 5 to drain adapter 6 and then assemble to unit with Phillips screws 7 .
c. Bubbler Stream - Bubble can be rotated slightly to direct the stream backwards or forwards.
Adjust the stream to minimize splashing. Splashing can occur from bubble stream if the unit is
not level. Shim lower mounting point, if necessary, to level chiller.
2. Compressor Does Not Run:
8. Make-up 1-1/4” outer diameter waste connection.
3. If water flow requires adjustment, insert a slotted narrow blade screwdriver in the hole centered on
the pushbutton of the fixture to the flow regulator. Turning clockwise will increase flow and turning
counterclockwise will decrease flow.
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. Change the overload or relay if defective.
c. A restriction or moisture in the system will also cause intermittent cycling. A certified refrigeration
mechanic should be contacted in this situation.
c. Check for twists or kinks in outlet tubing.
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.
g. 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.
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.
a. A dirty condenser or a blocked fan will cause a high head pressure and frequent cycling of the
overload protector.
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.
4. Compressor Cycling On Overload Protector:
b. Check the incoming voltage to make sure it is within 10% of the serial nameplate rating.
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.
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.
f. Check flow adjustment. See start up note #3.
h. No power to transformer connections, loose or wires cut.
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
7. Water Drips Or Will Not Shut Off:

a. Verify 120VAC input & 9VDC output transformer output 9VDC.
b. Replace Defective Transformer.
tighten to lock in place.
c. Transformer polarity crossed. Replace transformer, sensor may be damaged and also need to
be replacement.
d. Sensor in “Security Mode” after 30 seconds of consistent detection. Remove source of detection
and wait 30 seconds before checking.
e. Sensor is picking up a highly reflective surface. Eliminate cause of reflection and wait 30
seconds before checking.
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.
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. There is debris or scale in the center or two hole in convolution of the water diaphragm. Remove
and clean.
a. Repair bad connection from sensor to solenoid.
b. There is debris or scale in the solenoid assembly. Remove solenoid, pull out plunger and spring.
Clean with scale remover solution.
9. If Light Within Sensor Lens Flashes Once When User Is Within Range:
1. Motors have lifetime lubrication and do not require scheduled maintenance.
CLEANING & MAINTENANCE GUIDE:
f. Replace sensor.
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.
