MOUNTING CONFIGURATION
AS SHIPPED

IMPORTANT:
1. Water supply is 3/8” Outside Diameter Copper Tube. Waste is 1-1/4” Outside Diameter.
2. Completely flush supply lines of all foreign debris before connecting to fixture. Drinking Fountain 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.
3. Do NOT solder Copper Tube when inserted into the Coupler as damage to the O-Ring will result.
4. All burrs must be removed from outside of cut tubes before inserting into Coupler or other components.
5. WARNING: Warranty is voided if installation is not made following current Murdock Mfg. installation instructions
and if components are assembled to the fixture that is not approved by Murdock Mfg.
6. Fixture operates within water pressure range of 20 to 105 PSIG (138 to 724 kPa). Murdock Mfg. will not warranty
fixtures damaged when connected to supply lines with flow pressure lower than 20 PSIG (138 kPa) or higher than
105 PSIG (724 kPa). A pressure regulator must be furnished by others on supply line if inlet pressure is greater
than 105 PSIG (724 kPa).
7. 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:
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 Drinking Fountain. If wall can not provide adequate support, order and install optional fixture support
carrier.
2. Remove the Bottom Cover from the Drinking Fountain 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 water supply and assembling Bottom Cover to Drinking Fountain, 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 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 the Pushbutton 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.
5. Assemble Bottom Cover to Drinking Fountain with Screws furnished.
Hang the Drinking Fountain on the Hanger Brackets ensuring the Bracket Tabs engage AND seat in the slots in the
back of the Drinking Fountain. Verify Drinking Fountain are level, left to right AND front to back from bottom of unit.
NOTE: 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 Drinking Fountain to the wall at the lower mounting points in each Back Panel. Shim lower mounting
points to level unit if necessary.
5. Thoroughly flush the 3/8” O.D. supply line and then connect Drinking Fountain to Water Supply Angle Stop Valve (by
others) with supplied 3/8” O.D. Copper Tube.
6. Use supplied Flexible Hose and Clamps to connect Waste Tailpiece from the upper unit to the 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 Drinking Fountain.
2. Restricted Or No Water Flow
a. Ensure Water Supply Service Stop Valve is fully open.
b. Verify minimum 20 PSIG (138 kPa) 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. Flow control in Solenoid Valve Outlet Elbow clogged remove & clean.
h. No power to Power Supply connections, loose or wires cut.
3. 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 (2825 mNm) torque is required. If issue still continues after
adjusting flow and tightening Retainer Nut, replacement of the Flow Regulator Cartridge will be
required.
b. Replace Valve Cartridge.
4. If light within sensor does not flash once when user is within range:
a. Verify 120VAC input & 9VDC output transformer output 9VDC.
b. Replace defective transformer.
c. Transformer polarity crossed. Replace transformer, sensor may be damaged and also need 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.
5. 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 the center or two holes in convolution of the Water Diaphragm. Remove and
clean.
