6. When all flush valves are connected to the fixtures and water

pressure is available, it is recommended that the supply

piping be flushed to remove dirt, pipe chips, etc. from system.

Before the water is turned on, be sure all stop valves to the

flush valves are closed off tight. The stop valves can be

opened and closed by using the adjusting screw located at the

center of the stop valve cap, behind the stop cap cover if

already installed (see 6a). Stop valve adjustments can only be

made by using the adjusting screw. It is not necessary to

remove the stop valve cap when making adjustments. If

for any reason it becomes necessary to remove the stop

valve cap, be certain the water is shut off at the main

supply valve.

This procedure should also be followed when the system

has been drained for some time, as occurs in athletic fields,

recreation parks, etc.

7. The AquaVantage™ flush valves are preset for fixture volume

as marked on the valve cartons. The valve does not require

regulation for variation in water pressure within its operating

range. To set the flush valve for proper operation, gradually

adjust the stop valve open, using the adjusting screw, while

actuating the valve until the rate of water flow into the fixture

is not excessive, yet is sufficient enough to adequately evacu-

ate the waste. The final setting for urinals should be such that

the fixture will not overflow when the valve is actuated in suc-

cession. The stop cap cover should be secured after final

adjustments have been made.
