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.
