Flushometer
When G2 Optima Plus
®
has approximately 4,000 flushes left, the same red
light that appears at start-up will flash four (4) times quickly whenever an
object is detected. When this occurs, we recommend changing the batteries
as follows:
When required, replace batteries with four (4) alkaline type AA batteries.
Note: Water does not have to be turned off to replace batteries.
Loosen the two (2) screws on top of unit. Remove the complete cover
assembly. Lift the sensor module from its plate. Unplug the electrical
connector from battery compartment cover. Loosen the retaining screw on
battery compartment cover and remove battery compartment cover. Install
four (4) alkaline type AA batteries exactly as illustrated at right.
Install battery compartment cover and secure with retaining screw. Make
certain that battery compartment cover is fully compressed against gasket
to provide a seal; Do not overtighten. Plug the electrical connector into the
battery compartment cover. Reinstall the sensor module onto the plate.
Reinstall the complete cover assembly onto the plate. Tighten the two
(2) screws on top of the unit.

Range
The G2 Optima Plus has a factory set sensing range:
Water closet models – 22" to 42" (559 mm to 1067 mm)
Urinal models – 15" to 30" (381 mm to 762 mm)
The Factory setting should be satisfactory for most installations.
If the range is too short (i.e., not picking up users) or too long (i.e., picking
up opposite wall or stall door) the range can be adjusted.
Note: Water does not have to be turned off to adjust range.
Loosen the two screws on top of the unit. Remove the override button.
Remove the rubber plug from top of electronic sensor module to uncover
the potentiometer.
RANGE ADJUSTMENT PROCEDURE
For the first ten (10) minutes of operation, a visible red light flashes in the
sensing window of the G2 Optima Plus Flushometer when a user is
detected. This visible red light feature can be reactivated after ten (10)
minutes by opening and closing the battery compartment door or holding
the override button for (1) minute.
Check the range by stepping toward the unit until the red light flashes,
indicating the sensor’s detection of a user. Adjust the range potentiometer
screw located on top of the sensor module a few degrees CLOCKWISE to
increase the range or a few degrees COUNTERCLOCKWISE to decrease the
range. Repeat this adjustment until the desired range is achieved.
Always determine the sensing range with metal cover and lens
window on top of the unit.
Important: Adjust in small increments only! Range potentiometer
adjustment screw rotates only 3/4 of a turn; DO NOT over-rotate.
When range adjustment is satisfactory, replace the rubber plug. Reinstall
override button and tighten the two screws on top of the unit.
