DRAIN VALVE/TIMER CIRCUIT
Models D-HBT and D-H1T use a drain circuit consisting of a 3cr relay, 10 minute timer,
and a drain valve.
OPERATION:
1) When the power switch is pushed to the OFF position, the 3CR relay coil is then
energized, closing the 3CR contacts.
2) Drain timer now is powered from the 3CR relay, which opens the drain valve
for ten (10) minutes.
3) When the timer times out (10 minutes), the drain valve closes and machine has
completed it's drain cycle.
NOTE: Flip the power switch on the machine to ON then OFF position to open the drain
for an additional drain cycle. Repeat this step as necessary.
