Range Adjustment
The OPTIMA ETF-80 and ETF-880 Faucets are factory set to operate when
hands are placed 4 to 5 inches (102 to 127 mm) below the spray head.
This range should be satisfactory for most installations.
If range adjustment is required, refer to the following range adjustment
procedures.
TO MAKE A RANGE ADJUSTMENT
The Range Potentiometer and Dip Switches are located in Control Module.
Important: Range Potentiometer adjustment screw rotates only 3/4 of a
turn. DO NOT over-rotate.
Make certain that Dip Switch number 4 is in the UP position. Using the
small screwdriver provided, adjust Range Potentiometer clockwise until
green (power ON) indicator LED turns red (Faucet is now picking up sink).
Adjust Range Potentiometer back counterclockwise until red LED returns
to green. Range is now at maximum.
Cycle Faucet several times to assure that range as adjusted will not
inadvertently pick up IR reflection in lavatory. If IR reflection occurs (green
LED will flicker red), adjust Range Potentiometer counterclockwise very
slightly and again cycle Faucet.
Repeat range adjustment counterclockwise until length of range is at bowl
rim of lavatory (plus or minus 1 inch (25 mm)).
Time Out Adjustment
The Faucet Time Out Setting determines the maximum time the Faucet will
run upon continuous activation. This timing can be changed to meet
individual application requirements.
Refer to Table 1 or label on cover of Control Module along with the
following instructions to set the desired Time Out. The Dip Switches used
to set the Time Out are located in the Control Module.
Set the Time Out by configuring the number 1, 2 and 3 Dip Switches as
shown in Table 1.
Table 1 — Time Out Settings
Unless otherwise specified, all ETF-80 and ETF-880 Faucets leave the
factory set with a 30 second Time Out.
Note: The position of Dip Switch #4 (range enhancer setting) does not
affect Faucet Time Outs.
Push Cables into slots at the bottom of the Control Module.
Install Control Module Cover using Screws provided. Refer to illustration in
Step 7.

Test Faucet Operation
1. A continuous invisible beam of
infrared light is emitted from the
OPTIMA
®
Sensor located on the
throat of the lavatory faucet.
2. As the user’s hands enter the
beam’s effective range (beneath
the spray head), the beam is
reflected back into the sensor
receiver and activates the
solenoid valve allowing
tempered water to flow from the
faucet into the sink. Water will
flow until the hands are removed
or until the faucet reaches its
automatic time out limit setting.
3. When hands are moved away
from the OPTIMA
®
Sensor, the
loss of reflected light initiates an
electrical signal that deactivates
the Solenoid Valve, shutting off
the water flow. The Circuit then
automatically resets and is ready
for the next user.

CARE AND CLEANING OF CHROME AND
SPECIAL FINISHES
DO NOT use abrasive or chemical cleaners (including chlorine bleach)
to clean faucets that may dull the luster and attack the chrome or
special decorative finishes. Use ONLY soap and water, then wipe dry
with clean cloth or towel.
When cleaning the bathroom tile, protect the faucet from any
splattering of cleaner. Acids and cleaning fluids will discolor or remove
chrome plating.
