Operation and Installation Instructions for FloodMaster Water
Heater Leak Detection Alarm/Shutoff Systems – Model FM-0 4
The FM-094 series o Feed Water (Water Heater) Leak Detection and Shut O Systems is designed
to monitor and respond immediately to water leaks. When a sensor comes in contact with as little as
1/16th o an inch o water (or any other conductive liquid), it will automatically sound an audible alarm
and close the valve to shut down the water eed line, thus mitigating damage caused by an undetected
water leak. The unit also provides output signal capabilities (SPDT Relay Output Contact) or connection
to a home security panel or or use with an appropriate relay to control a secondary device, such as
a pump.
Output signal connections:
Normally Closed Circuit – Terminal Pins 3 & 4
Normally Open Circuit – Terminal Pins 4 & 5
The kit includes the receiver with on-board audible alarm, a ull port lead ree (NSF/ANSI 61 Annex G) shut-o valve, 110 VAC power supply, leak detection
sensor and a screw driver. Additional sensors can be added where a wider area o leak detection is required (additional sensors sold separately).
Installation Instructions: (FloodMaster recommends that installations be completed by a licensed plumber to ensure that all local code requirements are followed).
1. Turn o the water supply eed line to the water heater.
2. Thread the valve body into the eed water line a ter the manual shut-o . Apply pipe sealant or Te lon®tape
to the NPT threads and tighten.
3. The receiver connector comes pre-wired with basic connections to the power supply and the sensor. Using the
screwdriver provided, make any additional electrical connections as may be desired or output contacts or
additional sensors per the diagram provided. (Note: additional sensors can be connected to either 6 & or
8 & 9, as wiring space allows).
• Snap the terminal wiring block into the receiver housing at the mating slot provided.
4. Secure the valve body in one hand and snap the receiver into place on the valve body mounting pad.
(Note: Improper alignment of the valve stem may interfere with proper receiver mounting. If any resistance is encountered, confirm the witness mark on
the valve stem is in alignment with the ports of the valve. Use an appropriate hand tool, such as pliers, to clamp down on the valve stem and turn in the
appropriate direction until the desired position is achieved).
5. Plug the power trans ormer into a 120VAC wall outlet; the green Power indicator light on the receiver will turn on.
6. Function Test the system as follows:
a. Place the sensor on a wet paper towel.
b. The audible alarm will sound and the valve will rotate to the closed position.
c. The red Valve Closed LED will turn on when the valve is completely closed (approximately 45-second cycle time). Open a hot water aucet and
inspect or absence o water low. There should be no low.
d. Remove the sensor puck rom the paper towel, dry the contact points and place the sensor puck back in the desired location on the loor.
e. Press and release the Reset Button on the receiver to open the valve and begin the low o water again (approximately 45 seconds to ully open
position). The green Power indicator light will lash once to indicate the reset process has begun.
. Open a hot water aucet and inspect or water low.
Operation:
In the event the system activates, locate the source o the leak, remove the sensor rom the water and dry the metal contacts on the bottom. Correct the
problem causing the leak and replace the sensor in the desired leak detection location once again as required. Press and release the reset button on the
receiver to open the valve and begin the low o water again. The green Power indicator light on the receiver will lash once to con irm the reset.
Installation Manual
Maintenance:
We recommend an annual test o the unit to ensure proper unction. See Function Test instructions above. At a minimum, users should exercise (press and
release) the reset button on the receiver annually to ensure correct operation and to maintain product warranty status.
Emergency Manual Operation of the Valve:
The unit is equipped with an emergency eature or the manual rotation o the valve. This can be accomplished by disengaging the actuator rom the valve
and manually changing the valve to open or closed as ollows:
1. Unplug the unit rom the 120VAC wall outlet.
2. Stabilize the water eed line by grabbing it in one hand near the valve, while grasping the actuator housing in the other hand, pull the actuator housing
away rom the water eed line.
3. Using an appropriate hand tool, such as a pliers, clamp down on valve stem and turn in the appropriate direction until the desired position is achieved.
Note the top o the stem is slotted to indicate valve position (in line with water low would indicate open valve; slot across water line would indicate
closed valve).
4. Be ore remounting the actuator, return the valve to the original position prior to the manual rotation.
5. Remount the actuator and plug into 120 VAC wall outlet.
6. Test or correct operation per the Function Test listed above.
