3
Remove three o-rings (
7
) under rectan-
gular plate and replace with new o-rings
supplied with overrun controller.
4
Remove old pin (
11
) from module’s mid-
dle o-ring and replace with pin supplied
with overrun controller (
6
) (
† fig. 2
).
!
Notice
New pin (
6
) will sit higher than old
pin.
7
Place overrun controller onto top of pump
module, aligning o-rings (
7
) and pin (
6
)
with valve cap assembly (
5
) on bottom of
overrun controller.
8
Secure overrun controller onto pump us-
ing the four screws (
9
) removed from top
plate (
10
) by re-inserting screws into
holes at bottom of overrun controller
valve cap assembly (
5
).
9
Tighten screws (
9
) onto the pump.
10
Remove the four phillips screws
(
14
) on
overrun controller front (
8
).
11
Lift front cover panel (
15
)
from overrun
controller front (
8
).
12
Attach 9 V battery supplied with overrun
controller to the overrun controller via
the snap connector in the void in the
bottom right corner of the circuit board.
13
Press and release power button (
16
) on
rear of overrun controller front (
8
).
14
Viewing the digital display panel of
overrun controller front (
8
), confirm
display
lights up for 3 seconds.
!
Notice
Ensure all three wires under back
cover (

15
) to overrun
controller front (
8
) using phillips screws
(
14
).
17
Attach back cover (

Remote Monitoring
The option is available to connect the elec-
tronic air shutoff assembly to a remote
monitoring device such as a Programmable
Logic Controller (PLC).
Referring to
fig. 5, page 6
, a two-part
DIN connector is attached to the PCB hous-
ing of the electronic air shutoff assembly.
The socket half of the DIN connector can
be wired to carry pump operation status
signals directly to a PLC board or other
monitoring device.
