TROUBLE SHOOTING:
IMPORTANT: BEFORE MAKING ANY OF THE REPAIRS LISTED,
MAKE SURE THE WATER SUPPLY VALVE IS SHUT OFF.
1. ADJUSTMENTS:
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. 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:
a. Ensure water supply service stop valve is fully open.
b. Verify minimum 20 psig supply line flow pressure.
c. Check for twists or kinks in outlet 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. 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 transformer connections, loose or wires cut.
SENSOR TROUBLE SHOOTING:
3. 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.
4. 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.
