RDT FloodMaster RS-090-E User manual

Washing Machine Leak Detection &
Automatic Water Shut-Off Outlet Box System
Congratulations on your purchase of a Reliance Detection RS-090-E washing machine leak
detection system. This product is designed to automatically shut off the water supply to the
washing machine if a water leak is detected. To ensure proper installation and to maximize the
performance of your RS-090-E 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-090-E will shut off the water going to the washing machine. This
will stop the continuous ow of water from the water supply valves, but all or some of the water
that is already in the washing machine and hoses may still leak out onto the oor.
Complies with ASME A112.18/CSA B125.1-2012; NSF 372.
NOTE: The RS-090-E can be installed on existing or new washing machine installations.
Follow all applicable Federal, State and Local codes for installation. Valve(s) must be under
appropriate water pressure for performance testing.

1 – Leak detection receiver
1 – Water sensor with 8’ lead wire
1 – Metal plate for sensor placement
1 – Power transformer with 7’ lead wire
1 – Outlet box with mounting straps (4)
1 – Outlet box trim plate
2 – Water hammer arrestors
RS-090-E

IMPORTANT! For new construction/job site testing:
Valve(s) must be under appropriate water pressure for performance testing. Water pressure not
to exceed 80 PSI. The unit requires equalized water pressure in the leak detection assembly in
order to properly seat the valve upon closure. Do not cap appliance feeds during valve testing, as it
may interfere with water equalization. Do not test valve performance with air pressure. Testing the
valve with air pressure may cause the valve to not properly seat/leak and could damage the valve.
Note: While the valve will begin to close immediately, an initial burst of water will pass through
the appliance feeds. Consider placing a small bucket or similar container under the appliance
feeds when testing. Once the valve seats, all water ow will stop.
INSTALLATION INSTRUCTIONS
1. Turn off the hot and cold water valves to the washing machine. For existing installations,
disconnect washing machine hoses from existing water feeds, marking hoses as “hot” or
“cold.” Disconnect water supply lines from existing valves.
2. Determine the desired new valve and drain locations.
3. Mark and cut wall to t the RS-090-E outlet box (as necessary).
4. Secure the outlet box to the studs using provided mounting straps (4).
5. Using appropriate plumbing techniques, attach the supply lines to the water supply
connection lines (1/2” NPT standard; also accepts 1/2” copper pipe). Conrm that the
locknuts on the water supply connection lines are hand tight and ush to the outlet box.
6. Plug the power transformer into the leak detection receiver (30V AC) and plug into 120V AC
wall outlet. Observe green “Power” LED turn on.
7. Plug water sensor adapter into “Sensor” jack on the leak detection receiver.
8. Place water sensor in proximity to washing machine, in the area where a leak is most likely
to accumulate. (Note: The water sensor may be located underneath the washing machine as
desired or necessary.) The sensor is magnetic and can be installed horizontally or vertically
in conjunction with the metal plate – see Figure 1.
• 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.
9. Connect washing machine hoses to the appliance feeds of the leak detection receiver.
10. Open the water supply line and check for leaks.
11. Slide drain hose into drain opening of the outlet box and secure in place.
12. Perform this Function Test before installing the trim plate:
• Place the water sensor on a wet paper towel.
• The alarm LED should light up, the audible alarm should sound and water ow should stop.
• Wait 30 seconds and turn on the washing machine; no water should ow in.
• Remove the sensor from the paper towel. Return it to the area of desired leak detection.
• Press and release the reset button on the receiver to begin the ow of water to the washing
machine again. Wait 30 seconds and conrm water ow is back on.
13. Fit trim plate around the inside edge of the outlet box and put pressure on the plate until it
ts “ush” against the wall. The trim plate can accommodate up to 5/8” gypsum, with 1” of
cover all around the rough opening.
