Drain Blockage and Leak Detection Alarms
When treating hard water, scale may accumulate in the drain valves or drain line causing leaks to the drain or a plugged drain
line. The LCM-140 detects drain line plugging and leaks to the drain. If a drain plug is detected, the LCM system will
shut-down and all four indicator lights (blue and red) will blink in unison. For the LCM-140 model, if a drain leak is detected,
indicator lights C and D will blink. If either alarm is observed, reset the system by repowering it. This is done by detaching
and reattaching the power cord at the rear of the LCM. If the alarm occurs again, contact your Authorized Dealer for
maintenance.
