PRIOR TO INSTALLATION
Prior to installing the ZEG EcoVantage urinal flushometer
valve, install the items listed below:
• Urinal fixture
• Drain line
• Water supply line
1.)
Install stop valve assembly
(A)
using proper size supply
escutcheon and sweat solder adapter kit if applicable.
Note: Thread sealing compounds should be avoided.
Recommend teflon tape to seal NPT only.
3.)
Prior to inserting the flush valve tailpiece
(B)
into stop valve
(A)
, be certain that the O-ring seal
(C)
is located in O-ring
seal groove at the end of the tailpiece and that the locking
nut
(D)
and locking snap ring
(E)
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 sufficient.

Before the supply water is turned on, be sure all stop valves
are closed off tight. The stop valves can be opened and closed
by using the adjusting screw
(S)
located at the center of the
stop valve cap
(T)
. Stop valve adjustments can only be made
by using the adjusting screw
(S)
.
It is not necessary to re-
move the stop valve cap (T) when making adjustments. If
for any reason it becomes necessary to remove the stop
valve cap (T), be certain the water is shut off at the main
supply valve.

2.)
When all stops are connected to the water supply and
water pressure is available, it is recommended that the
supply piping be flushed to remove dirt, metal chips, etc.,
from system.
A. Before the valve is installed, open each stop fully for a brief
time and catch the water in a two gallon or larger bucket.
For multiple installations, start with the stop valve closest
to the water supply and work toward the most remote valve.
B. Due to the small passages and orifices, it is not possible
to flush the piping through the low volume valve.
C. Once the lines are flushed, the valve can be installed.

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 2).
• Dirt and debris can cause flush valve to run continuously.
• Sensor units should not be located across from each other
or in close proximity to highly reflective surfaces.
• DO NOT use pipe dope or plumbers grease on any part or
connection of this valve. These materials can block small
orifices in the flush valve and cause malfunctions.
The ZEG is designed to operate with 20 to 120 psi (138 to
827 kPa) of water pressure, however the required water pres-
sure is determined by the fixture. Contact the fixture manu-
facturer for the proper static and flow operating pressures.
Protect the chrome or special finish of this flushometer.
Do
not use toothed tools to install or service the valve.
