Controls and Product Issues

Consistency Adjustment

NOTE: The following product consistency (thickness) control adjustment procedure requires removal of the right side panel. It is suggested that a qualified service technician make this adjustment because side panel removal exposes hazardous moving parts.

Warning: Do not attempt freezer adjustments until electrical power has been disconnected.

It may become necessary to readjust the consistency setting (thickness) to compensate for variations.

1) Disconnect electrical power.

2) Remove right side panel (facing freezer).

3) Use the adjustment screw located on the top, front of the drive motor mounting bracket to change product thickness. (See Figure 17).

• Clockwise for thicker product consistency.

• Counterclockwise for thinner product consistency.

NOTE: It may require up to three 180° turns of this adjusting screw to see a noticeable change in product thickness.

4)Turn freezer to "ON" and allow it to freeze to desired consistency.

5)Wait 15 to 20 minutes, check product consistency (thickness) and repeat as needed.

6)Reinstall the side panel and reconnect power.

Mix Out Lights

Red indicator lights, located on the front of the freezer, illuminate if the unit runs out of CO2, syrup, water or alcohol.

When a light is on, the unit will not fill or freeze product.

Freezer Controls

NOTE: This dispenser has several power switches, that must be set in their operating position for the unit to operate properly.

"ON/OFF/CLEAN" SWITCH

The "ON/OFF/CLEAN" switch is a three-position toggle switch located on the front of the freezer. The left (facing the machine) position is the "ON" or freeze position. The middle position is the "OFF" position. The Right position is the "CLEAN" position (the auger is turning but the compressor is off).

Lower Base Control Panel Switches

All of the following switches are located on the lower control box, inside the rear cabinet door. (See Addendum 2 at the back of the manual)

Power Switch

This is the unit’s main power switch.

•On - power is supplied to the base unit.

•Off - No power is supplied to the base unit.

Control Switch

This switch determines whether the unit is in the test mode or operating mode.

•Test - The Test switch is used to check the BRIX of the product allowing the Timer Switch to control the solenoids.

•Off - Turns off the product feed system.

•Run - Allows product to be automatically fed to the freezer.

Timer Switch

•On - Activates the 10 second timer use to test BRIX and mix ratios

•Off - Timer is de-activated (normal operating setting).

Faceplate Relief Valves

A spring-loaded pressure relief valve maintains a safe pressure in the freezing cylinder. When filling the cylinder the relief valve acts as a vent to allow the CO2 and air trapped in the freezing cylinder to escape. Venting the freezing cylinder is essential to obtain proper overrun. The vent is also used to break a vacuum when draining a unit.

Dispensing Valve

CAUTION: The product in the freezing cylinder is under pressure, open the dispensing valve slowly when dispensing product.
