PRIOR TO INSTALLATION
Before you install the GEM•2
®
Flushometer, be sure the items listed below
are installed. Also, refer to the rough-in diagram on Page 2.
• Closet/urinal fixture
• Drain line
• Water supply line
Important:
• ALL PLUMBING SHOULD BE INSTALLED IN ACCORDANCE WITH
APPLICABLE CODES AND REGULATIONS.
• WATER SUPPLY LINES MUST BE SIZED TO PROVIDE AN ADEQUATE
VOLUME OF WATER FOR EACH FIXTURE.
• WHEN INSTALLING A FLUSHOMETER, IT IS IMPORTANT THAT THE
FLUSH MODEL MATCHES THE REQUIREMENTS OF THE PLUMBING
FIXTURE.
• FLUSH ALL WATER LINES PRIOR TO MAKING CONNECTIONS.
The Sloan GEM•2
®
Flushometer is designed to operate with 10 to 100 psi
(69 to 689 kPa) of water pressure. THE MINIMUM PRESSURE REQUIRED
TO THE VALVE IS DETERMINED BY THE TYPE OF FIXTURE SELECTED.
Consult fixture manufacturer for minimum pressure requirements. Most Low
Consumption water closets (1.6 gpf/6.0 Lpf) require a minimum flowing
pressure of 25 psi (172 kPa).
TOOLS REQUIRED FOR INSTALLATION
• Straight blade screwdriver
• Sloan A-50 Super-Wrench™, Sloan A-109 Plier Wrench or smooth
jawed spud wrench
With the exception of Control Stop Inlet, DO NOT use pipe sealant
or plumbing grease on any valve component or coupling!
!!! IMPORTANT !!!
Protect the chrome or special finish of Gem•2 Flushometers — DO
NOT USE toothed tools to install or service these valves. Use a
Sloan A-50 Super-Wrench™, Sloan A-109 Plier Wrench or smooth
jawed spud wrench to secure all couplings. Also see “Care and
Cleaning” section of this manual.
!!! 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.

CONTROL
STOP CAP
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.
