LIQUID LEVEL CONTROL
The system automatically maintains the hot water tank's level by energizing the refill solenoid when the water
level drops below the liquid level probe. If the system for the FMD-2 only has not successfully refilled in 7 1/2
minutes, a refill error occurs.
When a refill error occurs, the refill solenoid is de-energized and the rinse L.E.D. will flash about once every
5 seconds.
Once the cause of the refill error has been investigated (see the troubleshooting guide in the Operating and
Service Manual) and cured, the system can be reset by disconnecting (for at least 5 seconds) and then recon-
necting the power to the machine.
RINSE TIMER (FMD-2 ONLY)
The dispenser is shipped from the factory with the rinse timer disabled. To enable the rinse timer, remove
power from the dispenser, remove the lower access panel, and remove the jumper from J1 of the control board.
Replace the lower access panel, and return power to the dispenser.
When enabled, the rinse timer automatically keeps track of the time since the dispenser was last run through
a rinse sequence. If the dispenser detects that a rinse sequence has not been run for 8 hours, the rinse L.E.D.
will flash continually. If, after an additional 4 hours (12 hours total), a rinse sequence has still not been run, the
rinse L.E.D. will light continuously, and the hopper drives will be disabled until a rinse sequence has been run.
RUNNING A RINSE SEQUENCE
1. Place the rinse/run switch in the rinse position.
2. Sequentially, or simultaneously, at each of the two positions (FMD-2 only) dispense for at least 10 seconds.
3. After the rinse L.E.D. has extinguished, the rinse timer is reset (FMD-2 only).
4. Return the rinse/run switch to the run position.
DISPENSER USE
