LEAK DETECTOR INSTALLATION
LEAK DETECTOR INSTALLATION
This section provides instructions for connecting the Leak Detector to the iCOMM™
system’s CM (communication module). The Leak Detector comes with a 25 foot length of 18
gauge two conductor (18/2) SJ cord - see Figure 5. Operation is based on continuity; a water
level of approximately 1/4” will activate the Leak Detector.
INSTALLATION
1 Turn off power to the CM - unplug the 5 VDC round plug from the CM.
2 Locate the Leak Detector on the floor near the storage tank. Ensure the bottom of the Leak
Detector is laying flat on the floor. The Leak Detector does not need to be mounted or secured to
the floor. Choose a low traffic area to prevent disruption or damage to the Leak Detector.
3 Route the SJ cord from the Leak Detector back to the CM. Cut off any excess cord near the CM.
Secure the cord to walls and other suitable structures using wire tie wraps and mounts to provide
proper strain relief - see Figure 3 on page 8.
4 The wiring to the Leak Detector can be lengthened if necessary with similar 18 gauge wiring.
5 Split the end of the SJ cord and strip 1/4” of insulation from the two wires and connect them to the
“WATER DETECT” wiring terminal on the CM - see Figure 5. Unplug the “WATER DETECT”
wiring terminal from the CM when making connections and tighten terminal screws securely.
6 When Leak Detector installation is complete proceed to the Connecting Tank Type Water
Heaters section of this manual - see page 11.

Service Note - Alarms
If the Leak Detector is activated by rising water the CM and Alarm Box (if so equipped - see page 21) will sound an
audible and visual alarm. The alarms can be silenced/disabled by pressing the Display Button on the CM several
times - see Figure 5. The Leak Detector must dry out completely before the alarm condition can be cleared. The Leak
Detector will air dry over time or can be dried out with compressed air or a heat gun.

of water on the floor will activate
the Leak Detector.
