PRIOR TO INSTALLATION
Prior to installing the AquaSense “AV” Flushometer, install the items
listed below:
•Closet or urinal fi xture
•Drain line
•Water supply line
IMPORTANT:
• ALL PLUMBING IS TO 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.
• FLUSH ALL WATER LINES PRIOR TO OPERATION (See Step 9).
The AquaSense “AV” is designed to operate with 20 to 80 psi (138 to
552 kPa) of water pressure. THE MINIMUM PRESSURE REQUIRED TO
THE VALVE IS DETERMINED BY THE TYPE OF FIXTURE SELECTED.
Consult fi xture manufacturer for pressure requirements.
Protect the chrome or special fi nish of this fl ushometer. DO NOT USE
TOOTHED TOOLS TO INSTALL OR SERVICE THE VALVE.
4. Determine the length of vacuum breaker tube required to join the fl ush
valve and fi xture spud. Cut the vacuum breaker tube, if required, to this
length. Assemble the vacuum breaker tube assembly and spud nut
assembly to the fl ush valve and fi xture spud.
5. Hand tighten spud nut and vacuum breaker tube nut to fi xture and fl ush
valve. Adjust the valve assembly for plumb. Tighten fi xture spud nut,
vacuum breaker tube nut and lock nut with a wrench.
Do not turn water
on until batteries are inserted –see 8.
2. Prior to inserting the fl ush valve tailpiece into stop valve, be certain that
the o-ring seal is located in o-ring seal groove at the end of the tailpiece
and the locking nut and locking snap ring 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 suffi cient.
1. Install stop valve assembly using proper size supply escutcheon and
sweat solder adapter kit if applicable. Thread sealing compounds should
be used on male NPT threads only. Flush supply line by opening the
control stop. Turn on water supply to fl ush line of any debris or sediment.
Then close control stop.
