ERROR MESSAGES

“FILTER CLEANING” ALARM A filter cleaning alarm will activate when the unit is running hot due to insufficient internal air circulation. When this occurs a “Filtr” message will appear on the touchpad LED readout and an intermittent audible tone will also sound to alert the operator of this condition. The “Filtr” message will appear when the alarm activates (a beeping sound every 4-5 seconds). To determine the condition that caused the alarm and correct problem, see list of conditions below:

• Condition: Filter is dirty and needs to be cleaned

Corrective Action: Clean and replace filter following instructions.

• Condition: Unit is positioned too close to a wall or other objects restricting

air flow and causing the machine to run at a higher temperature. Corrective Action: Reposition unit to maximize ventilation space.

• Condition: Filter is not properly installed.

Corrective Action: Properly install filter.

• Condition: Unit has been installed near a heat source, such as a coffee

machine, ice maker or cold beverage machine which expels hot air from its vents, causing the machine to run at a high temperature. (Installation near a heat source should be avoided) Corrective Action: Reposition unit to maximize ventilation.

“SYSTEM OVER TEMPERATURE” ALARM

• A system over temperature alarm will activate as a safety when the unit has overheated to protect the compressor.

• The system automatically goes to “OFF” status where the compressor’s operations are stopped, while augers will keep working to avoid forming ice blocks.

• When this “Err” message will appear on the touch pad LED readout accompanied by a continuous buzzer sound to alert the operator of this condition.

• When this alarm activates, turn off all switches. Then determine the condition from the list above.

MG23-2B & ID2.2 TRADITIONAL ROCKER SWITCH MODEL GUIDE

Important: The mixing parts/auger switch should be on prior to activating the freezing or refrigeration switches.

(E) activates the mixing parts/spiral auger (F) activates the freezing of the product (G) activates the refrigeration of the product (D) is the main power switch FROZEN BEVERAGE - select (E) and (F)

Note: There is a 4 minute delay before the compressor starts.

COLD BEVERAGE - select (E) and (G) STANDBY (Night Setting) - select (E) and (G)

* Defrost timers are installed in each unit and can be set to automatically

place units in defrost mode and back to frozen mode. All switches must be on for defrost timer to properly function.

MG23-2B SETTING DEFROST TIMER (& ID2.2 When Equipped)

NOTE: All switches (power, auger, refrigeration and freeze) must be “on” for defrost timer to properly function.

• Setting Current Time - Rotate the program disc, in the direction of the arrows, to align the correct time of day with the time of day mark

• Setting Defrost Mode Push the switch activator toward the outer edge of the program disc. Freeze time is set by pushing the switch actuators toward the center of the time switch. The light and dark shaded areas of the program disc indicate day and night. Each actuator is equivalent to 15 minutes

• The drawing shows a defrost time from 11:00 to 6:15
