PRIOR TO INSTALLATION

Prior to installing the Piston Flushometer Valve, install the items listed below:

•Closet or urinal fixture

•Drain line

•Water supply line

The supply piping to these devices shall be securely anchored to the building structure to prevent the installed device from unnecessary movement when operated by the user. Care shall be exercised when installing the device to prevent marring the exposed significant surface.

IMPORTANT:

•ALL PLUMBING IS TO BE INSTALLED IN ACCORDANCE WITH APPLICABLE CODES AND REGULATIONS.

•WATER SUPPLY LINES MUST BE SIZED TO PROVIDE AN AD- EQUATE VOLUME OF WATER FOR EACH FIXTURE.

•FLUSH ALL WATERLINES PRIOR TO OPERATION.

The Piston Valve is designed to operate with water pressure as low as 10psi (69kPa). HOWEVER THE MINIMUM PRESSURE REQUIRED TO OPERATE THE VALVE IS DETERMINED BY THE TYPE OF FIXTURE SELECTED. Consult the fixture manufacturer for pressure requirements. Pressure in excess of 100psi (690kPa) is not suitable for flushing any plumbing fixture. Most codes mandate a maximum of 80psi; Please check local code requirements.Protect the chrome or special finish of this flushometer. DO NOT USE TOOTHED TOOLS TO INSTALL OR SER-

Binto the stop valve, be certain that the O-ring seal C is located in the O-ring seal groove at the end of the tailpiece, and the locking nut D and locking snap ring E are located as shown. Care should be taken not to damage the O-ring when inserting the tailpiece into the stop valve. If lubrication is needed, wetting the O-ring with water will be sufficient.

Insert the flushometer valve tailpiece B into the stop valve A and hand tighten the lock nut D to the stop valve. Plumb the entire unit.

Determine the length of vacuum breaker tube

Frequired to join the flushometer valve and fixture spud. Cut the vacuum breaker tube, if required, to this length. Assemble the vacuum breaker tube assembly and spud nut assem- bly to the flushometer valve and fixture spud.
