LIMITED WARRANTY - UNITED STATES & CANADA
Murdock warrants that its products are free from defects in material or workmanship under normal use and
service for a period of one year from date of original shipment or for 18 months after the date of shipment from the
factory, whichever comes first. Murdock’s liability under this warranty shall be discharged solely by replacement
or repair of defective material, provided Murdock is notified in writing within one year from date of shipment,
F.O.B. Industry, California.
This warranty does not cover installation or labor charges and does not apply to materials, which have been
damaged by other causes such as mishandling or improper care or abnormal use. The repair or replacement of the
defective materials shall constitute the sole remedy of the Buyer and the sole remedy of Murdock under this

WATER COOLERS
PRIOR TO INSTALLATION
Important: Some options may slightly alter installation. To ensure proper installation review the manual thoroughly
and verify rough-ins before beginning any work. File this manual with the owner or maintenance personnel upon
completion of installation
— Fixture mounting requirements: Industry standard wall construction, adequate to support the fixture and (installer
provided) wall anchors sufficient to secure the fixture.
— Fixture operates within water pressure range of 20 to 105 psig. Murdock will not warranty fixtures damaged when
connected to supply lines with flow pressure lower than 20 psig or higher than 105 psig.
— 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.
— Water supply inlet is 1/4” OD polyethylene tube.
— Completely flush supply of all foreign debris before connecting to fixture. Bottle filler is designed to provide trouble
free drinking water unaffected by fixture connection tubing and fittings and not cause problems with taste, odor,
color or sediment.
— It is common for electrical equipment to be grounded to water lines either within a structure or away from it.
Because this fixture is intended to dispense water that has been lowered in temperature, but otherwise remains
unchanged by the materials in the water cooler, every attempt should be made to prevent this kind of grounding
from generating feedback into the water cooler creating electrolysis. Electrolysis will cause a metallic taste or cause
water metal content to increase.
— Receptacle(s) must be wired to a GFCI protected circuit. Fixture must be earth grounded per N.E.C. (National
Electrical Code).
— Batteries are NOT included with this product. If using a battery pack provide 6 AA Alkaline or lithium batteries
INSTALLATION INSTRUCTIONS:
1. Remove drinking fountain access panel and shut off water supply , then actuate valve to relieve pressure.
Drilling Notes: (If ½” Hole Has Been Pre-Punched At The Factory Skip and Proceed to Step 3)
— Wear approved safety glasses when drilling.
— Prior to drilling stainless steel, adhere masking tape over drilling area to protect finish and provide
marking surface.
— Use a short, sharp high-speed drill bit and drill speed of 400-600 RPM; applying heavy pressure. Drill
must cut at all times. DO NOT allow to drill bit to ride, this will cause work hardening and will make
very difficult to drill or tap. Bibb washers, placed on drill shank will help to prevent marring the surface
after the drill has broke through.

TROUBLE SHOOTING:
1. IF LIGHT WITHIN SENSOR DOES NOT FLASH ONCE WHEN USER IS WITHIN RANGE:
a. Verify 120VAC input & 9VDC output of transformer/battery pack output 9VDC.
b. Replace defective transformer/batteries.
c. Transformer polarity crossed. Replace transformer sensor may be damaged
and also need replacement.
d. Sensor in “Security Mode” after 30 seconds of constant 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.
F. Replace defective sensor.
2. IF LIGHT WITHIN SENSOR LENS FLASHES ONCE WHEN THE USER IS WITHIN RANGE:
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.
c. There is debris or scale in center or two holes in convolution of the water diaphragm. Remove and
clean.
3. 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 twist or kinks in spout tubing.
d. Check the water inlet “Y’’ 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. Flow control in solenoid valve outlet elbow clogged remove & clean.
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.
g. Low or dead batteries.
j. No power to transformer connections loose or wires cut.
CLEANING & MAINTENANCE GUIDE:
1. To remove water spots or rust spots, stainless steel cleaner/polish on a cloth is recommended.
2. If there are stubborn spots or if you wish to treat a scratch, synthetic abrasive general purpose pads
such as scotch brite are recommended.
3. Apply stainless steel cleaner/polish to the synthetic abrasive pads and carefully rub the panel with
the grain.
4. Do NOT use harsh chemicals, abrasive or petroleum based cleaners. Use of these will
void the Acorn Engineering warranty. DO NOT use abrasives on powder coated units.
5. Stainless steel should be kept clean at all times. If a coating of stainless steel cleaner/
polish is maintained, stainless steel surfaces will retain their new, clean, polished appearance
indefinitely. Use clean mild soapy water for powder coated units.
6. Periodically remove access panel of cooler and clean out inline “Y’’ strainer. If battery powered,
replace batteries if needed. Remove top to access battery holder.
7. Low battery is indicated when light within sensor lens flashes multiple times, when activated.
