Before the water supply is turned on, be sure all stop valves to the flush valves are closed off tightly. The stop valves can be opened and closed by using the adjustment screw located at the center of the stop valve cap G, behind the adjustment screw cover if already installed. Stop valve ad- justments can only be made by using the adjust- ment screw. If for any reason, it becomes neces- sary to remove the stop valve cap G, be certain that the water is shut off at the main supply valve.
For new installations, we recommend the follow- ing steps:
Shut off stop valve and remove flushometer cover. Lift out the piston valve. Install the flushometer cover and open the stop valve to flush the line of any debris and sediment.
After completion, shut off the stop valve, remove the flushometer cover and reinstall the piston valve. Reinstall the flushometer cover securely. Open the stop valve and activate the flushometer valve.

Flushometer valves are preset for fixture volume as marked on the valve cartons. The valve does not require adjustment for variations in water pressure within its operating range. To set the flushometer valve for proper operation, open the stop valve completely by turning the adjustment screw and flush the Flushometer valve several times. Gradually adjust the stop valve down, us- ing the adjustment screw, so that the rate of wa- ter flow into the fixture is not excessive, yet is sufficient to adequately evacuate the waste. The final setting for urinals should be such that the fixture will not overflow when the valve is actu- ated several times in succession.
The stop cap screw cover should be replaced and tightly secured after final adjustments have been made.
