G2 Optima Plus®Flushometer
The Sloan Valve Company introduced its Optima Plus®battery operated
sensor Flushometer in 1992, revolutionizing the flushing of water closets
and urinals. In both new construction and retrofit applications, the use of the
Optima Plus has become the standard method for many facilities to improve
restroom hygiene and ensure handicap accessibility compliance.
In May, 2003 Sloan introduced the G2 Optima Plus.
The G2 Optima Plus builds on the success of the original product and offers
many technological advancements to further improve on performance and
reliability expected of sensor operated plumbing. In addition to a new
aesthetic design, the G2 Optima Plus features a new state-of-the-art
electronic and optical package and a unique solenoid operator that keeps the
moving components of the solenoid completely isolated from the water
supply. This ensures long life and low maintenance regardless of local
water condition.
The G2 Optima Plus replaces the original Optima Plus product, which was
phased out of production in mid-2003.
The Sloan G2 Optima Plus automatic battery powered Flushometer relies on
an infrared sensor to detect a user and activate a flushing cycle. No physical
contact with the Flushometer surface is necessary, assuring sanitary
protection. G2 Optima Plus Flushometers are ADA compliant devices.
The Flushometer is triggered by means of an active infrared sensor. The
Optima Plus sensor emits a continuous invisible light beam. When a user
enters the beam’s effective range, the beam is reflected into the Optima
Plus scanner window. The user is now detected. After the user moves out of
the effective range of the sensor, a signal is sent to the Flushometer
solenoid and, after appropriate arming and/or flush delays, the flush cycle
is initiated.

G2 Optima Plus®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.

Repair Parts and Maintenance Guide
G2 Optima Plus®Flushometer
IMPORTANT: This product contains mechanical and/or electrical
components that are subject to normal wear. These components should be
checked on a regular basis and replaced as needed to maintain the valve’s
performance.
Never open Control Stop to where the flow from the valve exceeds the flow
capability of the fixture. In the event of a valve failure, the fixture must be
able to accommodate a continuous flow from the valve.
ATTENTION INSTALLERS: With the exception of the control stop inlet,
DO NOT USE pipe sealant or plumbing grease on any valve component or
coupling! To protect the chrome or special finish of Sloan Flushometers,
DO NOT USE toothed tools to install or service these valves. Use our A-50
Super-Wrench™or other smooth-jawed wrench to secure couplings.
Regulations for low consumption fixtures (1.6 gpf/6.0 Lpf closets and
1.0 gpf/3.8 Lpf urinals) prohibit use of higher flush volumes.
1. Sensor flashes continuously only when user steps within range.
A. Unit in start-up mode; no problem. This feature is active for the first
ten (10) minutes of operation.
2. Valve does not flush; sensor not picking up user.
A. Range too short; increase the range.
3. Valve does not flush; sensor picking up opposite wall or surface,
or only flushes when someone walks by. Red light flashes
continuously for first 10 minutes even with no one in front of
the sensor.
A. Range too long; shorten range.
4. Valve does not flush even after adjustment.
A. Range adjustment potentiometer set at full “max” or full “min” setting.
Readjust potentiometer away from full “max” or “min” setting.
B. Batteries completely used up; replace batteries.
C. Problem with electronic sensor module; replace electronic sensor
module.
5. Unit flashes 4 quick times when user steps within range.
A. Batteries low; replace batteries.
6. Valve does not shut off.
A. By-pass orifice in diaphragm is clogged with dirt or debris, or by-pass
is clogged by an invisible gelatinous film due to “over-treated” water.
Remove flex tube diaphragm and wash under running water.
Note: Size of orifice in the by-pass is of utmost importance for the
proper metering of water by the valve. DO NOT ENLARGE OR
DAMAGE THIS ORIFICE. Replace flex tube diaphragm if cleaning
does not correct the problem.
B. Dirt or debris fouling stem or flex tube diaphragm. Remove flex tube
diaphragm and wash under running water.
C. O-ring on stem of flex tube diaphragm is damaged or worn. Replace
O-ring if necessary.
D. Problem with solenoid. If cleaning does not correct problem, replace
with new solenoid operator.
7. Not enough water to fixture.
A. Wrong flush volume regulator installed in flex tube diaphragm kit.
Install the correct regulator.
B. Wrong Optima Plus®model installed; i.e., 1.0 gpf urinal installed
on 3.5 gpf closet fixture. Replace with proper Optima Plus model.
C. Enlarged by-pass in diaphragm. Replace flex tube diaphragm.
D. Control stop not adjusted properly. Readjust control stop.
E. Inadequate volume or pressure at supply. Increase water pressure
or supply (flow) to valve. Consult factory for assistance.
8. Too much water to fixture.
A. Wrong flush volume regulator installed in flex tube diaphragm kit.
Install the correct regulator.
B. Control stop not adjusted properly. Readjust control stop.
C. Wrong Optima Plus model installed; i.e., 3 gpf model installed on 1.0
or 1.5 gpf urinal fixture.
D. Dirt in diaphragm by-pass. Clean under running water or replace flex
tube diaphragm.
Note: The EBV-46-A beam deflector is no longer required or available
for the G2 Optima Plus.
CARE AND CLEANING INSTRUCTIONS
DO NOT use abrasive or chemical cleaners to clean the G2 Optima Plus, they
may dull the luster and attack the plastic cover and the chrome finish of the
Flushometer. Use ONLY mild soap and water, then wipe dry with clean cloth
or towel. While cleaning the bathroom tile, the Optima Plus should be
protected from any splattering of cleaner. Acids and cleaning fluids can
discolor or remove chrome plating.
