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

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

•When this alarm activates, turn off all switches. Then determine the condition. (See “Filter Cleaning” Alarm Section for Conditions and Corrective Actions)

2.) SETTING DEFROST MODE - Set the defrost period by pushing the switch actuator toward the outer edge of the program disc. Freeze time is set by pushing the switch actuators toward the center of the time switch. Figure N shows a defrost time

from 11:00 to 6:15. The light and dark shaded areas of the program disc indicate day and night respectively. Each actuator is equivalent to 15 minutes.

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

NOTE: The timer is battery backed. Do not remove power from the unit for greater than 2 weeks as doing so will result in failure of the battery back-up feature. The battery is nickel cadmium and will last from 6 to 8 years if properly charged. The battery is not replaceable upon failure.
