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 require a minimum flowing pressure of 25 psi
(172 kPa). Many building codes and the ASME A112.19.2 fixture standard
list maximum static water pressure as 80 PSI.
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.

!!! IMPORTANT !!!
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.
