RDT FloodMaster RS-094 User manual

Water Heater / Tank Leak Detection &
Automatic Shut-Off System
Congratulations on your purchase of a FloodMaster RS-094 water heater leak detection system
from Reliance Detection Technologies. This product is designed to automatically shut off the
water supply to a water heater or tank if a leak is detected.
To ensure proper installation and to maximize the performance of your RS-094 water leak
detection system, please read this manual thoroughly before installing or operating the system.
PLEASE READ CAREFULLY BEFORE PROCEEDING:
If a leak is detected, the RS-094 will shut off the water going to the water heater. This will stop
the continuous ow of water from the water supply to the tank. However, all or some of the
water that is already in the tank may still leak out onto the oor.
NOTE: This installation and operating manual contains important information about the operation of the
RS-094 system. If this system is being installed for use by a different user, please be sure a copy of this
manual is left with the system for future reference.

RS-094

NOTE: The RS-094 can be installed on existing or new water heater installations. RDT recommends that
installations be completed by a licensed plumber to ensure that all local code requirements are followed.
INSTALLATION INSTRUCTIONS
1. Turn off the water supply feed line to the water heater.
2. Prior to installation, manually exercise the valve body to fully closed and back to fully open
position by holding it in your hand, applying a pliers to the valve stem and turning. Thread the
valve body into the feed water line after the manual shut-off. Apply pipe sealant or Teon®
tape to the NPT threads and tighten.
3. The receiver connector comes prewired with basic connections to the power supply and the
sensor. Using an appropriate screwdriver, make any additional electrical connections as may
be desired for output contacts or additional sensors per wiring Figure 1. (Note: additional
sensors can be connected to either 6 & 7 or 8 & 9, as wiring space allows.) Then 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, conrm the witness mark on the valve stem is in
alignment with the valve ports. 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. Place the sensor(s) where water is most likely to rst accumulate (such as the drain pan
or the oor next to the tank). The sensor is magnetic and can be installed horizontally or
vertically in conjunction with the metal plate – see Figure 2.
• Clean the desired location area to ensure the surface is clean for optimum plate adhesion.
• Peel the backing off the metal plate to reveal the adhesive and stick in place.
• Place the sensor on the plate as close as possible to the oor, allowing the magnets to
secure it in place.
Note: The sensor features a through-hole that can be used to screw it onto a surface if a more
permanent installation is desired or necessary.
6. Plug the power supply into an 120V AC wall outlet. The green “Power” indicator light on the
receiver will turn on.
7. Function Test the system as follows:
• Place the sensor on a wet paper towel. The audible alarm will sound and the valve will
rotate to the closed position.
• The red “Valve Closed” LED will turn on when the valve is completely closed (approximately
45-second cycle time). Open a hot water faucet and conrm that there is no water ow.
• Remove the sensor from the paper towel, dry the contact points, and place it back in the
desired location on the metal plate.
• Press and release the “Reset” button on the receiver to open the valve and begin the ow
of water again (approximately 45 seconds to fully re-open). The green “Power” indicator
light will ash once to indicate the reset process has begun.
• Open a hot water faucet and inspect for water ow.
OUTPUT SIGNAL CONNECTIONS
The unit also provides output signal capabilities (SPDT Relay Output Contact) for connection to
a home security panel or for use with an appropriate relay to control a secondary device, such as
a pump. See Figure 1 for wiring diagram.

Warning: For use with water only. Do not install on gas line. Never install this device
on a re protection or re suppression system. For indoor use only.
OPERATION & SYSTEM RESET
In the event the system activates, locate the source of the leak, remove the sensor from 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 ow of water again.
The green “Power” indicator light on the receiver will ash once to conrm the reset.
MAINTENANCE
Test the system annually per the function test (install step 7) to ensure correct operation and to
maintain product warranty status. At a minimum, users should exercise (press and release) the
“Reset” button on the receiver annually.
EMERGENCY MANUAL VALVE OPERATION
The unit is equipped with an emergency feature for the manual rotation of the valve. This can be
accomplished by disengaging the actuator from the valve and manually changing the valve to
open or closed as follows:
1. Unplug the unit from the 120V AC wall outlet.
2. Stabilize the water feed line by grabbing it in one hand near the valve. While grasping the
actuator housing in the other hand, pull the actuator housing away from the water feed 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 of the stem
is slotted to indicate valve position (in line with water ow would indicate open valve;
slot across water line would indicate closed valve).
4. Before remounting the actuator, return the valve to the original position prior to the
manual rotation.
5. Remount the actuator and plug into 120V AC wall outlet.
6. Test for correct operation per the function test listed in install step 7.
