G2 Optima
®
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  ow from the valve exceeds the  ow
capability of the  xture. In the event of a valve failure, the  xture must be
able to accommodate a continuous  ow 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  nish of Sloan  ushometers,
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  xtures (1.6 gpf/6.0 Lpf closets and
1.0 gpf/3.8 Lpf urinals) prohibit use of higher  ush volumes.
1. Sensor fl ashes continuously only when user steps within range.
A. Unit in start-up mode; no problem. This feature is active for the  rst
ten (10) minutes of operation.
2. Valve does not fl ush; sensor not picking up user.
A. Range too short; increase the range.
3. Valve does not fl ush; sensor picking up opposite wall or surface,
or only fl ushes when someone walks by. Red light fl ashes
continuously for fi rst 10 minutes even with no one in front of
the sensor.
A. Range too long; shorten range.
4. Valve does not fl ush 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 fl ashes 4 quick times when user steps within range.
A. Batteries low; replace batteries.
6. Valve does not shut off.
A. By-pass ori ce in diaphragm is clogged with dirt or debris, or by-pass
is clogged by an invisible gelatinous  lm due to “over-treated” water.
Remove  ex tube diaphragm and wash under running water.
Note: Size of ori ce 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  ex tube diaphragm if cleaning
does not correct the problem.
B. Dirt or debris fouling stem or  ex tube diaphragm. Remove  ex tube
diaphragm and wash under running water.
C. O-ring on stem of  ex 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 fi xture.
A. Wrong  ush volume regulator installed in  ex 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  xture. Replace with proper Optima Plus model.
C. Enlarged by-pass in diaphragm. Replace  ex tube diaphragm.
D. Control stop not adjusted properly. Readjust control stop.
E. Inadequate volume or pressure at supply. Increase water pressure
or supply ( ow) to valve. Consult factory for assistance.
8. Too much water to fi xture.
A. Wrong  ush volume regulator installed in  ex 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  xture.
D. Dirt in diaphragm by-pass. Clean under running water or replace  ex
tube diaphragm.
Note: The EBV-46-A beam de ector 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  ushometer, they
may dull the luster and attack the plastic cover and the chrome  nish of the
 ushometer. 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  uids can discolor or remove
chrome plating.
When assistance is required, please contact
