SOLENOID FILTER CLEANING PROCEDURE

Turn off water supply at supply stop(s). Activate faucet to relieve system pressure.
Remove water supply line from inlet side of solenoid valve. Remove cap, water
line fitting, gasket, filter housing and filter from solenoid valve housing. Slide
filter off filter housing. Clean filter using fresh tap water only. If necessary, use a
small brush to clean. Use caution while cleaning to prevent damage to filter.
If any filter components are damaged, replace as necessary. Examine the gasket
for wear or damage; replace if necessary. Reinstall filter on filter housing. Install
filter housing, gasket, water line fitting and cap onto solenoid valve housing.

START-UP PROCEDURE

1

Activate faucet by placing hands in front of the sensor. The solenoid valve should
“click.” Once hands are removed you should here another click. Once segment is
complete, remove spray head. Open supply stop(s) then activate faucet by placing
hands in front of sensor. The solenoid valve should “click” and water should flow
from the spout. Activate faucet for 30 seconds by keeping hands in front of the
sensor. Close supply stop(s) and reinstall spray head in spout using the key 
provided. Reopen supply stop(s), activate faucet and check for leaks. If you 
have problems with any of the above steps working, refer to the Troubleshooting 
section in this manual.

(MODE) JUMPER SETTINGS

1

For jumper settings, refer to chart above or label on cover of control module along
with the instructions in this step.

Noise Reduction (NR) Setting

• When operating the faucet on batteries
   alone, set the NR jumper to bridge pins
   1 and 2.
• When operating the faucet using the
   plug-in transformer with battery backup,
   bridge pins 2 and 3.

Time Out (Mode) Setting

The faucet time out setting determines
the maximum time the faucet will run
upon continuous activation. This timing
can be changes to meet individual 
requirements. Faucets are factory set
with a 30 second time out.

Faucet is factory set to operate when hands are placed 4" to 5" from sensor. If
range adjustment is required, the range potentiometer and dip switches are
located in control module. Range potentiometer adjustment screw rotates only
3/4 of a turn, DO NOT over-rotate. Make certain that Dip Switch #4 is in the UP
position. Adjust range potentiometer clockwise until green (power ON) indicator 
LED turns red - faucet is now picking up sink.Turn back counterclockwise until
red LED returns to green. Range is now at maximum. Repeat adjustment counter-
clockwise until length of range is at bowl rim of lavatory (plus or minus 1").

Time out Adjustment

The faucet time out setting 
determines the maximum time
the faucet will run on continuous
activation. Refer to table at right
