MAINTENANCE GUIDE FOR THE ETF-660 & ETF-770 FAUCET
1
 PROBLEM:
No water is delivered when faucet is activated.
INDICATOR:
If no LED lights illuminate.
CAUSES:
A) No electricity is being supplied to faucet.
B) There is an electrical system malfunction.
SOLUTION:
A) Ensure that the main power is turned "ON". Check all transformer, sensor, solenoid and cable connections. Make sure that transformer is supplying 24 VAC (Volts AC). If no voltage is detected, replace transformer.
B) Reset electrical system. Unplug Sensor connection. Disconnect power to circuit for ten (10) seconds. Reconnect.
INDICATOR:
If the GREEN LED illuminates when the power is reconnected.
CAUSE:
C) There is a short in the Sensor.
D) There is a short in the Solenoid or Solenoid cable.
SOLUTION:
C) Replace Sensor with #52857 from Equiparts. For old style, replace both #52857 AND #08462. Refer to individual faucet parts diagram for appropriate Sensor Assembly. NOTE: GREEN LED may illuminate immediately after Sensor disconnection.
D) Replace # 8367 (ETF-370-A) Solenoid. To order, call Equiparts at 800-442-6622.
INDICATOR:
If the GREEN LED does NOT illuminate when
the power is reconnected
CAUSE:
E) There is an electrical system malfunction.
F) The Control Module circuit is "dead."
SOLUTION:
E) Reset electrical system. Unplug Sensor connection. Disconnect power to circuit for ten (10) seconds. Reconnect.
F) Replace # 8462 (ETF-450-A) Control Module. To order, call Equiparts at 800-442-6622.
INDICATOR:
If the GREEN LED illuminates AND changes to RED when hands are in the Sensor's detection zone AND the RED Solenoid LED illuminates.
CAUSE:
G) Water Supply Stop(s) may be partially closed.
H) Debris is clogging Solenoid Filter
SOLUTION:
G) Open Supply Stop(s) if closed.
H) Shut off water supply. Remove, clean and reinstall
Solenoid Filter. If needed, replace Solenoid Filter by ordering part # 08633 from Equiparts. Call 800-442-6622 to order.
INDICATOR:

If the GREEN LED illuminates AND changes to RED when hands are placed in the Sensor's detection zone, AND the RED solenoid LED flickers with a vibrating/clicking noise heard inside the module.

Note: Applies only to REVISION 2 MODULES.
CAUSE:
I) There is a direct short in the Solenoid or Solenoid cable.
SOLUTION:
I) Replace with an # 8367 (ETF-370-A) solenoid from Equiparts. Call 800-442-6622 to order.
INDICATOR:
If the GREEN/RED LED illuminates AND changes to RED when hands are NOT located in the sensor's detection zone, BUT the RED solenoid LED (in upper left corner of circuit) does NOT illuminate.
CAUSE:
J) Sensor range is too long and is detecting the sink.
K) Sensor is faulty
SOLUTION:
J) Reduce Sensor detection range.
K) Replace Sensor. Refer to individual faucet parts diagram for appropriate Sensor Assembly.
1
INDICATOR:
(Cont.) If the GREEN LED illuminates BUT does NOT change to red when hands are placed in the Sensor's detection zone.
CAUSE:
L) Sensor range is set too short.
M) Sensor is faulty
SOLUTION:
L) Increase Sensor detection range.
M) Replace Sensor. Refer to individual faucet parts diagram for appropriate Sensor Assembly. Call Equiparts for assistance at 800-442-6622.
2
 PROBLEM:
Sensing Range is too short.
CAUSES:
A) Extended Range Sensitivity is required.
B) Faucet has Surgical Bend Gooseneck Spout.
SOLUTIONS:
A) Dip Switch number 4 should be in the "DOWN" (Extended Range Sensitivity) position. Increase range by adjusting range potentiometer clockwise (yellow phillips screw in blue base).

B) For Long Range use (recommended for Surgical Bend Gooseneck Spout faucet models,) remove Range Jumper from upper right hand corner of circuit board. Adjust range potentiometer.

Note: Applies only to REVISION 2 MODULES.
3
 PROBLEM:
Faucet activates by itself (false triggers).
CAUSE:
A) Sensor range is set too long.
SOLUTION:
A) Decrease range by adjusting range potentiometer counterclockwise. If necessary, flip Dip Switch number 4 into the "UP" (Reduced Range Sensitivity) position. Check surroundings for factors that contribute to Sensor range detection problems (bright lights, highly reflective surfaces, sunlight, etc.)
4
 PROBLEM:
Faucet delivers very low flow or just a dribble
CAUSE:
A) Water Supply Stop(s) may be partially closed.
B) Debris is clogging Solenoid Filter.
C) Solenoid is worn or faulty.
D) Debris is clogging faucet Aerator or Spray Head.
SOLUTIONS:
A) Open stop(s).
B) Shut off water. Remove, clean, and reinstall Solenoid Filter. Replace Solenoid Filter if necessary, by ordering part # 08633 from Equiparts. Call 800-442-6622 to order.
C) Replace Solenoid - part # 08367. Call Equiparts at 800-442-6622 to order.
D) Shut off water. Use key if required to remove. Then clean and reinstall Aerator or Spray Head.
5
 PROBLEM:
Faucet does not stop delivering water or continues to drip after user is no longer detected (even after power to the Module has been disconnected.)
CAUSE:
A) Solenoid Valve is installed backward.
B) Debris is clogging Solenoid
C) Seat in Solenoid valve body is damaged or pitted.
SOLUTIONS:
A) Disconnect Solenoid. Reconnect Solenoid with water flow towards the faucet (see arrow on Solenoid).
B) Remove and clean Solenoid operator. If necessary, rebuild with # 8633 (ETF-1009-A) Repair Kit. Call Equiparts to order at 800-442-6622.
C) Replace with # 8367 (ETF-370-A) Solenoid. Call Equiparts to order at 800-442-6622.
