Installation Guide
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 screw 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.

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 op er a tion, open the
stop valve completely by using the ad just ing screw and flush
the AquaVantage several times. Gradually adjust the stop
valve, using the adjusting screw, so that the rate of water flow
into the fixture is not ex ces sive, yet is sufficient enough to
ad e quate ly evacuate the waste. The final setting for urinals
should be such that the fixture will not overflow when the
valve is actuated twenty times in succession. The stop cap
cover screw should be secured after final adjustments have
been made.

Use the following procedure to flush out the supply piping:
A. Remove the main valve body cover.
B. Remove the working parts from the flush valve (shown in 6b).
C. Replace the main valve body cover and plastic cover
without reinstalling the working parts.
D. Open the stop valve by using the stop adjusting screw and
flush out all debris from pipe and connections.
E. Shut stop, open cover, replace the working parts, replace
and tighten the cover.
This procedure should also be followed when the system
has been drained for some time, as occurs in athletic fields,
recreation parks, etc.
