A
Thread Locking Ring
onto Valve Body.
B
Use Strap Wrench
provided to tightly secure
Locking Ring.
If retrofitting the Optima Plus onto a Zurn valve body, a special Locking
Ring must be used (identified by a machined groove around the ring).
Order the Optima Plus with the “Z” variation to receive the unit supplied
with this Ring.
A
Remove all removable objects
in sensor view area and remove
the Tab located over the Override
Button to activate the Sensor
Module. The sensor module will
perform the start-up routine for
one minute with LED blinking.
B
After the start-up routine is
complete, for the first ten (10)
minutes of operation, a Visible
Red Light flashes in the Sensing
Window of the Optima Plus
Flushometer when a user is
detected.
9 - TIGHTEN LOCKING RING
10 - REMOVE TAB TO ACTIVATE SENSOR MODULE
The Locking Ring must be installed down past the valve body
threads by at least one thread. If difficulty is experienced
installing the Locking Ring, turn the Locking Ring back and
forth, each time working it further down the threads. The
Locking Ring will act as a thread chaser in the event there has
been a build-up of matter on the threads of the old valve body.
!!! IMPORTANT !!!
The self adaptive sensor automatically adapts to the surrounding
enviroment when the tab on the override button is removed.
No manual adjustments are required. Start-up mode will take
approximately one (1) minute to complete its cycle and it is important
that no non-permanent target is present at this time. If the target is
permanent, the sensor will adapt itself around this target. A 3 seconds
long Red light on and followed with slow Red light blinking in sensor
window indicates sensor is in the start-up mode. When the start-
up cycle is complete, one red light blink indicates lithium batteries
are installed and two red light blinks indicates alkaline batteries are
installed.
