a. Verify 120VAC input & 9VDC output transformer output 9VDC.
7. WATER DRIPS OR WILL NOT SHUT OFF:
b. Replace valve cartridge.
a. Repair bad connection from sensor to solenoid.
1. To Remove water spots or rust spots, stainless steel cleaner/polish on a cloth is

1.
Motors have lifetime lubrication and do not require scheduled maintenance.
2.
Excess dirt or poor ventilation will cause the compressor overload protector to turn the compressor off and it
will cycle on and off with no cold water coming out of bubbler. Periodically clean with vacuum cleaner, air
hose or brush the condenser fins and cabinet ventilation louvers. In environments where dirt and dust is
more prevalent, clean more frequently.
3.
Periodically remove fountain top and clean out in-line strainer.
4.

9. IF LIGHT WITHIN SENSOR LENS FLASHES ONCE WHEN THE USER IS WITHIN RANGE:
e. Sensor is picking up a highly reflective surface. Eliminate cause of reflection and wait 30 seconds before
checking.
2. If there are stubborn spots or if you wish to treat a scratch, using synthetic abrasive general
purpose pads, such as Scotch-Brite™, are recommended.
4. DO NOT use harsh chemicals, abrasive or petroleum based cleaners. Use of these will
void the Murdock 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.
