Time Delay Relay
The time delay relay may be used with the MSLV to delay
solenoid valve shut-off, providing a post flush. This helps
prevent drain line stoppages and is beneficial when ground
food waste must travel through many bends or down a
long horizontal run in the drain line. It is adjustable from 0
to 10 minutes and factory-set to provide an approximately
5-minute delay. To adjust the time, SHUT OFF ELECTRIC
POWER. Inside the unit, locate the adjustment knob. Turn
clockwise to increase delay or turn counterclockwise to
decrease delay. See figure 4 for wiring.
Ensure the voltage rating on the time delay and solenoid
valve are 24 volts.
