3.3 OPERATING CONTROLS

It is required that the operator know the function of each control or component on the freezer before operating. Refer to Fig.8 for the location of the operating controls.

3.4 SPIGOT SWITCH

The SPIGOT SWITCH will automatically activate the auger drive and refrigeration system when the spigot switch is opened to draw product.

3.5 DRIVE MOTOR OVERLOAD

The internal DRIVE MOTOR OVERLOAD will trip if the drive motor is overloaded. It will reset after approximately 10-12 minutes. If the drive motor continues to trip, refer to troubleshooting.

3.6 POWER SWITCH (Clean-Off-Serve)

The POWER switch is a three-position toggle switch used to control the operation of the refrigeration system and auger. When the switch is placed in the CLEAN position, the refrigeration system will be off and the auger will rotate for cleaning.

When the switch is placed in the OFF position, the refrigeration system and the auger are inoperative. When the switch is placed in the SERVE position, the refrigeration system and auger will be controlled automatically. The switch must be placed in the SERVE position for normal operation.

3.7 FREEZING SWITCH

The FREEZING switch is a two-position toggle switch used to control the operation of the auger drive and refrigeration system. When the switch is placed in the MAXIMUM po- sition, the freezer will continue to run for a minimum of 30 seconds after the spigot is closed. This time cycle provides make-up cooling periods of heavy dispensing. Heavy dispensing is drawing more than 18 ounces (.53 liters) in one minute.

When the switch is placed in the NORMAL position, the freezer will continue to run for a minimum of 5 seconds after the spigot is closed. This time cycle is to be used during periods of normal dispensing. Normal dispensing is drawing less than 18 ounce (.53 liters) in one minute.

NOTE

Do not leave the switch in the MAXIMUM position during slow or moderate dispensing as the product temperature will become too cold.

3.8 DOOR INTERLOCK SWITCH

When the door is securely fastened the freezer will operate normally. When the door is removed the drive and compressor will not run.

3.9 REMOTE PUMP SWITCH

The OFF-ON REMOTE PUMP SWITCH is a two-position switch. When wired in series with the model 219 or U3 REMOTE PUMP OFF, pump operation can be controlled from the front of the freezer. With the 219 or U3 REMOTE PUMP OFF-ON SWITCH in the ON position, place the OFF-ON pump switch in the ON position and the pump will start. Place the OFF-ON switch in the OFF position and the pump will stop.

3.10 DISPENSE RATE ADJUSTER

The dispense rate adjuster limits the opening of the spigot. To adjust product dispense rate, turn the adjusting knob clockwise for slower flow and counter-clockwise for faster flow.

3.11 HIGH PRESSURE CUT OUT

If the head pressure exceeds 405 PSIG the high head pressure cut out will trip. The reset button can be accessed from the lower front of the freezer.

3.12 SANITIZING PROCEDURES

For sanitizing to be effective, it must be performed after the mix pump and freezer parts have been cleaned, and just prior to filling the hopper or storage container with mix. Sanitizing the night before is not effective.

When sanitizing the freezer, refer to local sanitary regulations for applicable codes and recommended sanitizing products and procedures. The frequency of sanitizing must comply with local health regulations. Mix sanitizer according to manufacturer’s instructions to provide a 100 parts per million strength solution. Mix sanitizer in quantities of no less than 2 gallons (7.5 liters) of 120° F water. Allow sanitizer to contact the surfaces to be sanitized for 5 minutes. Any sanitizer must be used only in accordance with the manufacturer’s instructions.
