ADJUSTMENTS
The beverage solenoid is preset to dispense approximately 9/10 ounce per second. This amount can be ad-
justed:
1. Disconnect the dispenser from the power source.
2. Remove the small left side access panel to adjust dispense valves 1, 2 & 3, and remove the small right side
access panel to adjust dispense valves 4 & 5.
3. Rotate the control at the base of the solenoid clockwise to decrease or counterclockwise to increase the
amount of water.
4. Replace appropriate access panels when finished.
HOPPER MOTOR SPEED PROGRAMING
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 30 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.
DRAINING THE HOT WATER TANK
CAUTION - The dispenser must be disconnected from the power source throughout these steps.
1. Disconnect the dispenser from the power source.
2. Place the tank heater switch in the “OFF” position.
3. Shut-off and disconnect the incoming water supply.
4. Remove the front, lower access panel.
5. Pull out drain tube to empty into a sink or a container with a minimum of 6-1/2 gallon capacity.
6. Make sure drain clamp is closed. Then, remove drain plug.
7. Direct tube into sink or container and open drain clamp. Continue draining tank until ALL of the water is
out.
WARNING: Be very careful with the draining water because it can be very hot.
8. Close drain clamp, insert drain plug, place drain tube back into machine, and replace lower access panel.
NOTE - The dispenser must be refilled using the INITIAL FILL & HEAT steps before reconnecting to the power
source.
