STEP 2 – Optional Battery Backup and Low Battery
Indicator Light Installation
• If the battery backup option is being utilized, it is neces sary to
install the battery pack mounting plate and the battery pack
close to the power converter in a convenient location for battery
replacement when needed.
• Mount the battery pack mounting bracket.
• Clip the battery pack into location and secure the battery pack
to the bracket with the securing screw.
NOTE: Do not install
the batteries until the Flushometers are
completely installed and operating. The batteries do not have
to be installed for the system to function.
STEP 3 – Control Stop Installation
(Figure 6)
Install the Zurn control stop valve with “Siphon Gard” back check
protection (and wall escutcheon on exposed Flushometer installa -
tions) to the water supply line with the outlet positioned as required.
NOTE:
For sweat solder applications, see recommended
instructions included in the Zurn sweat solder kit.
STEP 4 – Install Vacuum Breaker Flush Connection
Models ZEMS6000, ZEMS6000-2 and ZEMS6000-3
(Figure 7)
Slide the tube nut, slip washer, rubber gasket and spud escutcheon
over the vacuum breaker tube and insert tube into fixture spud.
Hand tighten spud coupling into fixture spud.
Models ZEMS6140, ZEMS6142 and ZEMS6152
(Figure 8)
NOTE:
When cutting scoriated pipe, leave a minimum of 1-1/4"
of scoriation to ensure engagement with compression coupling.
Assemble pipe, elbows, couplings, slip washers, rubber gaskets
and flanges as illustrated in Figure 8. Hand tighten all couplings.
Once installation is completed, tighten all connections.
STEP 5 – Actuator Cable Installation
(Figures 9 and 10)
1. Drill 1-3/4" diameter hole per Figure 9.
2. Run “fish tape” from electrical box to 1-3/4" hole.
3. Install actuator escutcheon to the actuator pipe with set screw
toward actuator. Do not tighten setscrew at this time.
4. Pull actuator cable through hole with fish tape and back to
electrical box. Secure armored cable to box with box clamp.
5. With escutcheon loose and handle port washer installed, push
cable into wall. The actuator must be angled away from the
valve body at this time until the actuator push rod clears the
handle port flange. The actuator can now be mounted to the
flush valve and tightened.
6. Push escutcheon back to wall and tighten setscrew.
7. The actuator back cover has vent holes top and bottom. After
assembly, the top hole should be sealed with a small dab of
clear silicone sealant.
NOTE:
See Figure 10 for typical installation including optional
mini junction box.
