Prior to Installation:
• The ZER-TM ushometer is designed to operate optimally between 25 psi (running) to 80 psi (static) water pressure (172 to 552
kPa). Higher running pressure may be required for some xtures. Consult xture manufacturer for details.
• When installing a ushometer, it is important that the ush volume matches the requirements of the plumbing xture.
• To protect chrome nish, do not use toothed tools to install or service the ushometer.
• Before installing your Zurn®Gear Driven Flush valve, the items listed below should already be installed on site:
- Closet or urinal xture
- Fixture carrier
- Drain line
- Water supply line
Overview:
Zurn Aqua-Sense® ZER-TM Series Flushometer o󰀨ers two models (closet/urinal) in a variety of ow rates. The ZER-TM
design is a chrome plated brass body with an automatic sensor-operated gear driven valve. The ushometer incorporates a
ltered bypass, high back pressure vacuum breaker, adjustable tailpiece, spud coupling, ange for top spud connection and an
electronic override pushbutton (MOB) for alternative ushing method. The control stop has internal siphon-guard protection,
vandal resistant stop cap, sweat solder kit, and cast wall ange with set screw. All internal and external gaskets and seals are
chloramine resistant.
NOTE: The information in this manual is subject to change at any time without notice. Installations may
be performed at di󰀨erent times of construction by di󰀨erent individuals. For this reason, these instructions
should be left on-site with the facility or maintenance manager.
Specications:
Voltage: 6 VDC Series [4 “AA” 1.5V Lithium Cells] or 6 VDC Series [4 “AA” 1.5V Alkaline Cells]
Sensor Range: Factory set for user at end of elongated bowl or eld adjustable by installer
Important Safety Information:
• Installer is responsible for ensuring the product is installed and conforms to all plumbing codes and ordinances.
• Do not convert or modify this Zurn product yourself. All warranties will be voided.
• Water supply lines must be sized according to building designer in order to provide adequate water supply for each xture.

1. Measure distance from nished wall to the center line of the xture
spud. If necessary, cut water supply pipe 1-1/4” shorter than this
measurement. Deburr by chamfering O.D. and I.D of end of water
supply pipe.
NOTE: Before installation, turn o󰀨 water supplies to existing xture and remove ushometer if replacing an existing device.

2. Slide threaded sweat solder adapter onto water supply pipe until
shoulder stops on end of pipe. Then sweat-solder the adapter to
water supply pipe.
3. Measure distance from nished wall to rst thread of sweat solder
adapter. If necessary, cut chrome cover tube this length.
4. Slide wall escutcheon over chrome cover tube and slide both
items over water supply pipe. Press wall escutcheon ush against
nished wall and tighten set screw with hex wrench (supplied) to
secure it in place.
Using a athead screwdriver,
turning counterclockwise, ush
supply line by opening the
control stop. Turning clockwise
will close control stop.

1. Install control stop assembly by threading it onto water supply
pipe and tightening with a smooth jawed wrench. Apply thread
sealing compound or pipe tape to male NPT thread on sweat
solder adapter only.
2. When all stop valves are properly connected to the water
supply line and water pressure is available open the control
stop using a athead screwdriver and turning the stop valve
adjustment screw counterclockwise.
Prior to turning on main water supply line ensure all stop valves
are closed o󰀨 tight by using a athead screwdriver and turning
the stop valve adjustment screw clockwise.
Allow the water supply line to ush any debris or sediment that
may be present in the line. Close the control stop once the
lines are completely ushed.

STEP 3.1
Prior to attaching ush valve to control stop(A) inspect and verify
that the O-ring (C) is located within the O-ring groove at the tailpiece.
Ensure the locking nut (D) and locking snap ring (E) are also present
on the tailpiece. See Figure 7.
STEP 3.2
Lubricate O-ring with water and carefully insert ush valve tailpiece
into the control stop valve to ensure O-ring remains seated. Tighten
locking nut using a smooth jawed wrench. See Figure 8.
Flush Valve Installation - STEP 3
STEP 3.3
Determine the length of vacuum breaker tube required to join the
ush valve and xture spud, and cut if necessary.
STEP 3.4
Slide the tube nut, spud nut, slip gasket, rubber gasket and spud
escutcheon over the vacuum breaker tube and insert tube into
xture spud. Hand tighten tube nut to valve body and hand
tighten spud nut onto xture spud. Adjust the valve assembly for
plumb. Tighten xture spud nut, vacuum breaker tube nut and
lock nut with a wrench.
Adjust and plumb the valve assembly. Tighten all connections with
smooth jawed wrench and turn on water supply at the control stop.
See Figure 9.
DO NOT use pipe sealant or plumbing grease on any valve
component or coupling with the exception of the Control Stop
Inlet! Ensure Vacuum Breaker does not twist or warp when
tightening Vacuum Breaker Tube Nut.
DO NOT cut vacuum breaker tube shorter than 6” below
the -C-L- indicator mark, as vacuum breaker must be 6” above
the xture. Consult plumbing Codes & Regulations for specic
details.
