style is set to OFF (Refer to page 19 for setting the audible alarm style).
High Cabinet Air Temperature:
The audible alarm* will sound and the display will read
HI
CAb
when the temperature inside the cabinet rises above a pre-programmed limit. The limit is
determined by the type of unit being operated (i.e.: refrigerator/freezer). To turn off the audible
alarm*, press the alarm cancel button. The visual alarm text will continue to display until the
cabinet air temperature falls below the limit. If the temperature does not fall below the limit
within 5 minutes, the audible alarm* will sound again and an additional Call Service message
will display.
POSSIBLE CAUSES (for Refrigerator & Freezer Models):
•
Doors open for extended periods of time.
•
Large amounts of hot product placed inside the cabinet.
•
Condenser coil dirty.
Low Cabinet Air Temperature:
The audible alarm* will sound and the display will read
Lo
CAb
when the temperature inside the cabinet falls below a pre-programmed limit. The limit is
determined by the type of unit being operated (i.e.: refrigerator/ freezer). To turn off the audible
alarm*, press the alarm cancel button. The visual alarm text will continue to display until the
cabinet air temperature rises above the limit. If the temperature does not rise above the limit
within 5 minutes, the audible alarm* will sound again and an additional Call Service message
will display.
POSSIBLE CAUSES (for Refrigerator & Freezer Models):
•
No product in unit.
•
Failed sensors.

the unit regains power after an outage. To turn off the audible alarm* and/or clear the visual
text, press the alarm cancel button. You must reset the clock and date if you are using any
defrost lockouts or are retrieving the information
from the data storage memory. See

POSSIBLE CAUSES:
•
Low refrigerant charge.

Discharge sensor has failed low.
CONDENSERCLEAN™:
The audible alarm* will sound and the display will read Clean
Filter, when the operating pressures and temperatures exceed a safe operating range. As the
load on the condenser decreases, the alarm will turn off by itself. As the pressures on the
condenser continues to rise, the audible alarm* will stay on for longer periods of time. To turn
off the audible alarm*, press the alarm cancel button. The visual alarm text will remain until the
filter/condenser has been cleaned. If the condition remains for 24 hours, the audible alarm* will
sound again and visual display will read Call Service.

Service, when any of the unit sensors fail to operate. To turn off the audible alarm*, press the
alarm cancel button. The visual alarm text will remain until the sensor has been replaced.
