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.

!!! IMPORTANT !!!

With the exception of Control Stop Inlet, DO NOT use pipe sealant or plumbing

grease on any valve component or coupling!

!!! IMPORTANT !!!

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.

!!! 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.

The Sloan GEM•2 (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.

Flushometer is designed to operate with 10 to 100 psi

TOOLS REQUIRED FOR INSTALLATION

• Straight blade screwdriver

• Sloan A-50 Super-Wrench™, Sloan A-109 Plier Wrench or smooth jawed spud wrench

Align Flushometer directly above the

Vacuum Breaker Flush Connection by sliding the Flushometer Body IN or OUT as needed. Tighten Vacuum Breaker Coupling by hand.

Maximum adjustment of the Sloan Adjustable Tailpiece is

1/2” (13 mm) IN or OUT from the standard 4-3/4” (121 mm)

(centerline of Flushometer to centerline of Control Stop).

If roughing-in measurement exceeds 5-1/4” (133 mm),

consult factory for longer tailpiece.

Align Flushometer Body and securely tighten first the Tailpiece

Coupling (1), then the Vacuum Breaker Coupling (2), and finally the Spud Coupling (3). Use a wrench to tighten these couplings in the order shown.

If not installed, install Handle Assembly with Gasket to handle

opening on Flushometer Body. Tighten Handle Assembly securely.

!!! IMPORTANT !!!

The Sloan Gem•2 Flushometer is engineered for quiet operation.

Excessive water flow creates noise, while too little water flow may

not satisfy the needs of the fixture. Proper adjustment is made when

plumbing fixture is cleansed after each flush without splashing water out

from the lip AND a quiet flushing cycle is achieved.

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.

TROUBLESHOOTING GUIDE

1. Valve does not function (no flush).

A. Control Stop or Main Valve is Closed. Open Control Stop or Main Valve. B. Handle Assembly is worn. Replace Sloan Handle Assembly (G-143-A). C. Relief Valve is worn and sticking in UP position. Replace Piston.

2. Volume of water is not sufficient to siphon fixture.

A. Control Stop not open enough. Adjust Control Stop for desired delivery of

water.

B. Urinal Piston Parts inside a Closet Flushometer. Replace Piston Parts with

proper Closet Piston.

C. Low Consumption Flushometer installed on a non-Low Consumption fixture.

Replace with proper Piston Kit.

D. Inadequate volume or pressure at supply. Increase water pressure or supply

(flow) to Flushometer. Consult Factory for assistance.

3. Length of flush is too short (Short Flushing) or Flushometer closes off immediately.

A. Piston Assembly is not hand-tight. Screw the assembly hand-tight. B. Enlarged Bypass orifice from corrosion or damage. Install NEW Inside Piston

Kit to correct problem and update Flushometer. C. Urinal Piston in Closet Flushometer. Replace Piston with proper Closet Piston. D. Low Consumption Piston installed in non-Low Consumption fixture. Replace

Piston with proper Closet Piston. E. Handle Assembly is worn. Replace Sloan Handle Assembly (G-143-A).

4. Length of flush is too long (Long Flushing) or fails to close off.

A. Piston is not seating properly or Bypass orifice is clogged because of foreign

material, or Bypass orifice is closed by an invisible gelatinous film from “overtreated” water.

Disassemble the working parts and wash thoroughly. NOTE: SIZE OF THE

ORIFICE IN THE BYPASS IS OF UTMOST IMPORTANCE FOR THE PROPER METERING OF WATER INTO THE UPPER CHAMBER OF THE FLUSHOMETER. DO NOT ENLARGE OR DAMAGE THIS ORIFICE. REPLACE PISTON IF CLEANING DOES NOT CORRECT PROBLEM.

B. Line pressure has dropped and is not sufficient to force Relief Valve to seat.

Shut off all control stops until pressure has been restored, then open them again.

C. 3.5 gpf Closet Piston has been used in a 1.0 or 1.5 gpf Urinal or on a 1.6 gpf

Toilet. Replace with proper Piston.

D. G-21 Main Seat is fouled with debris or is worn. Clean or replace G-21 Main

Seat.

5. Leaking at Handle Assembly.

A. The B-39 Seal is worn or deteriorated. Install new B-39 Seal. NOTE: The B-39

Seal will easily slide onto the Bushing if it is wet. B. Handle gasket has been omitted. Replace Sloan Handle Assembly (G-143-A). C. Valve Handle Bushing is worn. Replace Sloan Handle Assembly (G-143-A).

Refer to the GEM•2 Flushometer Maintenance Guide for additional Troubleshooting and Repair Part information.

CARE AND CLEANING OF CHROME AND SPECIAL FINISHES

DO NOT use abrasive or chemical cleaners (including chlorine bleach) to clean Flushometers that may dull the luster and attack the chrome or special decorative finishes. Use ONLY mild soap and water, then wipe dry with clean cloth or towel.

While cleaning the bathroom tile, protect the Flushometer from any splattering of cleaner. Acids and cleaning fluids will discolor or remove chrome plating.
