TROUBLE SHOOTING:
c. Check for twists or kinks in outlet tubing.
b. Replace valve cartridge.
a. Verify 120VAC input & 9VDC output transformer output 9VDC.
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 point, if necessary, to level chiller.
2. RESTRICTED OR NO WATER FLOW:
g. Flow control in solenoid valve outlet elbow clogged remove & clean.
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.
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.
b. Verify minimum 20 psig supply line flow pressure.
h. No power to transformer connections, loose or wires cut.
a. Ensure water supply service stop valve is fully open.
SENSOR TROUBLE SHOOTING:
4. IF LIGHT WITHIN SENSOR DOES NOT FLASH ONCE WHEN USER IS WITHIN RANGE:
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.
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.
c. Transformer polarity crossed. Replace transformer, sensor may be damaged and also need replacement.
3. WATER DRIPS OR WILL NOT SHUT OFF:
1. ADJUSTMENTS:
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 tighten to lock in place.
d. Sensor in “Security Mode” after 30 seconds of consistent detection. Remove source of detection and wait
30 seconds before checking.
c. There is debris or scale in the center or two holes in convolution of the water diaphragm. Remove and
clean.
f. Check flow adjustment. See start up note #3.
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.
b. Replace defective transformer.
b. There is debris or scale in the solenoid assembly. Remove solenoid, pull out plunger and spring. Clean
with scale remover solution.
