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.
IMPORTANT : ASSUREZ-VOUS QUE LA FONTAINE D'EAU POTABLE RÉFRIGÉRÉE SOIT DÉBRANCHÉE DE LA
PRISE DE COURANT MURALE ET QUE LE ROBINET D'ALIMENTATION D'EAU SOIT FRMÉ AVANT
D'EFFECTUER LES RÉPARATIONS NÉCESSAIRES.
