Once cycled through all three primary menus the keyboard
returns to the locked position. If no button is pushed for 30
seconds the display goes blank and returns to the locked
position.
Note: If the FloodBreaker is attached to an external
power source, the display always remains active.
In the standard leak protection mode the system monitors the
water volume used without any interruption, the length of time
water is used without interruption as well as the flow rate.
Should one of the following criteria be exceeded, the device
suspects a leak, closes the valve and displays a shut-off
code.
1. Volume-based leak – Message A3 is displayed if the
water volume used exceeds the set limit without inter-
ruption.
2. Flow rate – Message A4 is displayed if 15.5 GPM is
exceeded for the set period of time.
3. Time-based leak – Message A9 is displayed when con-
stant flow is detected over a time limit based on the fol-
lowing settings. To override the default time see section
6.3.
If you are not using an external power source, press any
button to activate the display. LE appears in the display
window. If vacation leak mode is activated UL appears in

the instructions in 5.2 and select the -- leak setting shown in
Figure 6. After saving and returning to the home screen, “0” will
be displayed during the deactivation period.
During periods when the house may be unoccupied a tighter leak
protection may be desired. This can be accomplished using the
vacation leak mode and does not require changing the normal
leak protection setting. When activated it overrides the standard
leak protection.
The vacation leak protection is adjustable from 3-26 gallons of
uninterrupted flow. If the vacation leak setting is exceeded a leak
is suspected, the FloodBreaker closes thus shutting off the water
and the Message A5 is displayed.

The 48 hour monitor is an additional method to check for
leaks. This function can be used when you may be away from
home for longer than several hours and have not activated
the vacation leak protection. When this monitor is activated
and no water is drawn off for 48 hours, the FloodBreaker
closes to isolate the system for 3 minutes.
After three minutes the device opens again and verifies
whether there is a flow of water. If it detects a flow of 81⁄2
ounces, a leak is suspected and the device will close.
Message A8 is displayed.
The 48 hour leak monitor is factory shipped in the off
mode.
Enter and unlock the Advance Menu Settings. 4- is shown
and the (-) will be blinking, indicating that the setting can be
changed and the monitor is in the deactivated position
(Figure 13).
Set the monitor to the active position by pressing the or
button so the number (8) is displayed instead of the -.
To save the settings press the button.
The time-based protection is factory set to the off position.
When the time-based leak protection is activated, the
default time setting used in conjunction with the standard
leak setting is replaced by this new setting. (See section 5.1
for default time settings).
Example: With a Standard Leak Protection setting of 1-4
the default time would be 2 hours. If the time-based leak
protection is activated and set to 8 hours, the new time set-
ting for any Standard Leak Protection is 8 hours. This
would mean that the FloodBreaker would not suspect a
leak until either the set volume of water is reached or a flow
of water is detected for 8 continuous hours.
Press the button until the display shows t1 (Figure 14).
Press the button again and use the or buttons
to adjust the number of hours that continuous flow is
acceptable before the unit closes. Save any changes by
pressing the button.
The factory setting is 1 minute. If the flow rate exceeds 15.5
GPM for 1 minute a leak is suspected, the valve will close
and message A4 is displayed.
The maximum flow rate is not adjustable. The time limit can
be adjusted between 1 to 30 minutes. It cannot be turned
off.

The FloodBreaker will not be suitable for installations that
will exceed 15.5 GPM for 30 minutes or longer.

Press the button until the time-based flow rate menu is
displayed as t2 (Figure 15).
Press the button again and use the or buttons
to set how many minutes the FloodBreaker waits before
shutting off the water supply when the flow exceeds 15.5
GPM (Figure 16).
Save the change by pressing the button again.
This feature allows the FloodBreaker to double check for a
leak when a volume-based leak is detected. The factory
setting is deactivated or off (E-).
When the recheck feature is activated (E1) and the
FloodBreaker detects a leak, it shuts off the water. It will re-
open after 30 seconds to see if water is actually being
drawn off. If water flow is detected the valve will close and
not open again until it is reset. If no water flow is detected
the valve will remain open and allow water usage up to the
set points.
Press the up or down button to activate (E1) or de-
activate (E-) (Figure 17).
Press the button to save the change.
This is a dry contact with a 24Volt/2amp maximum switch-
ing capability.
The primary use for this contact would be an external alarm
display or signal. The factory setting is o1.

For the most complete protection, the FloodBreaker should
be installed on the home’s incoming water supply and as
close to where the supply enters as possible. (Check with
local authorities for any restrictions.) The FloodBreaker
uses a universal body assembly and can be installed into
either a vertical or horizontal pipe line as shown (Figure 32).
Install the union nuts and tailpieces onto the piping system
before attaching them to the FloodBreaker body. Be sure to
mount the body in the correct flow orientation. The triangle on
one end of the body indicates the direction of flow (Figure 33).
The FloodBreaker universal body may now be attached to
the tailpieces already installed in the piping as shown
(Figure 32).
Note: Remove the clear protective plastic covering
from the face of the universal body.
Flush the piping before attaching the FloodBreaker to the
body. (Figure 34).
Attach the FloodBreaker to the universal flange body using
the 2 O-rings and the 4 body bolts provided (Figure 35).
