10.) The ZTS6200 series valve comes preset for both flow vol-
ume and sensing distance. Each valve is operated at the
factory using water to insure proper function before being
packed for shipment. The valve does not require water pres-
sure regulation for variation in water pressure within the
specified pressure range (40 psi to 116 psi) due to internal
pressure regulation.
Open the stop valve to wide open position using the adjust-
ing screw (S) on the front of the stop valve.
Install vandal resistant stop cover to complete the installa-
tion. See Figure 10.
11.) LOWBATTERYWARNING
The LED will flash at a constant rate when an object is de-
tected as the batteries reach a predetermined depletion level.
The battery must be replaced within two weeks. The LED
will continue the flash sequence until the batteries are re-
placed.
12.) BATTERY REPLACEMENT - See Figure 12
A.) Turn off the stop valve. (A)
B.) Remove the cover screw and remove the cap.
See Figure 11
C.) Replace the battery with a new 9V battery.
D.) Before reassembling the electronic cap (L), make sure ex-
ternal o-ring is not damaged. Replace if necessary.
E.) Make sure inside of cap is dry before reconnecting the sole-
noid valve connector (J).
F.) Assemble the cap (L).
G.) Tighten the screws.
APPENDIX A - See Figure 13
TO CHANGE DETECTION RANGE
The sensor range is the distance an object can be away from
the sensor in order to activate the flush valve. The sensor is
factory preset to approximately 33.5” +/- 3.0”. If necessary, it
can be adjusted as follows:
1.) Disconnect the battery from the sensor (see Battery
Replacement, step 12).
2.) Make a short between the (+) positive and (-) negative
terminals of the connector using a screwdriver or another
conductor material.
3.) Reconnect the battery to the sensor.
Note: There is a 5 second window after connecting the
battery in which the sensor range adjust mode can be
accessed.
4.) Place your hand in front of the sensor at a distance of 2” to
4” within 5 seconds after battery is reconnected to enter
sensor range adjust mode.
5.) Initially the red light in the sensor will flash slowly 3 times
(approximately 2 seconds per flash). Keep your hand in
front of the sensor until you see the light begin to flash in
rapid succession approximately 4-6 seconds.
6.) Immediately place target (try not to use black or white) at
the required distance from sensor (approximately at the
end of the bowl). When the red light flashes for a duration
of 3-4 seconds the sensor has been adjusted to the
required distance. Note: For targets, the back of a note-
book or a piece of cardboard work well.
7.) Check the distance you have set by placing target a
distance greater than the end of the bowl. Move the target
slowly towards the sensor. When you see the sensor light
flash once note this distance the sensor is set to. If the
sensor is not set to the reqiured distance (approximately
the end of the bowl), repeat steps 1-6 to correct.

13.) Care and Cleaning
A. Ensure any flush valve containing or utilizing electronics is
not pressure washed. Water and cleaner blown through the
seals at high pressures damage the electronics and
internals.
B. Ensure cleaners containing ammonia or chlorine com-
pounds (especially ammonium chloride) to sanitize flush
valves are not used because they will chemically etch the
polycarbonate plastic lens preventing IR from being trans-
mitted, and damage the chrome plated finish. Mild, non-
abrasive antibacterial soap and water while using a soft
cloth is recommended. Avoid use of abrasive applicators
such as scotch-brite pads, steel wool, & brushes. A good
rule of thumb is: Do not use anything stronger than what you
would wash yourself with.
