2.Remove product hopper(s).

3.Remove the hole plug(s) in the auger motor mounting panel.

4.Rotate the control at the base of the solenoid clockwise to decrease or counterclockwise to increase the amount of water.

5.Reinstall plug(s) and hopper(s).

HOPPER MOTOR SPEED ADJUSTMENT (FMD-1)

The hopper dispense rate is preset at the factory. With 8 tooth gear and auger wire the preset dispense rate is approximately 3 to 5 grams per second. With 12 tooth gear and auger wire the preset dispense rate is approxi- mately 5 to 7 grams per second. The hopper dispense rate can be adjusted to a range of dispense rates from approximately 1.5 to 12 grams per second, as follows:

1.Set the tank heater switch to the off position.

2.Open the top front cover of the dispenser and remove the two screws securing the top cover.

3.Remove the top cover assembly and set it aside.

4.Locate the motor speed adjuster (leftmost) on the dispenser cabinet top cross member.

5.Using extreme care not to touch the live terminals of the tank heater, adjust the motor speed by rotating the motor speed adjuster to the desired point, ranging from minimum (full counterclockwise) to maximum (full clockwise.)

6.After the motor adjustment is complete, replace the top cover assembly, securing it with the two screws, and return the tank heater switch to the on position. 

HOPPER MOTOR SPEED PROGRAMING (FMD-2)

The hopper dispense rate is preset at the factory. With 22 tooth gear and auger wire the preset dispense rate is approximately 3 to 5 grams per second. With 32 tooth gear and auger wire the preset dispense rate is approxi- mately 5 to 7 grams per second. The hopper dispense rate can be adjusted to a range of dispense rates from approximately 1.5 to 12 grams per second, as follows:

1.Place the rinse/run switch in the center (program) position.

2.Place the increase/decrease switch in the desired (increase or decrease) position.

3.Press and release the dispense switch for the chamber you wish to adjust. Each time the dispense switch is pressed, the rinse L.E.D. will flash, and the motor speed for that hopper will be increased/decreased by approximately 2 1/2%.

4.Return the rinse/run switch to the run position after hopper motor speed adjustments are complete.
