OPERATION

All cabinets must be given sufficient time to reach normal operating temperature before placing any food inside. Refrigerators are designed to maintain an ideal cabinet temperature of 38`f to 40`f (3.3`c to 4.4`c) and approximately 2 hours of operation are required to reach this temperature. Standard freezers are designed to maintain an ideal cabinet temperature of -2`f to 0`f (-18.9`c to -17.8`c) and approximately 4 hours of operation are required to reach this temperature. Low temperature freezers are designed to maintain an ideal cabinet temperature of -16`f to -14`f (-26.7`c to -25.6`c) and approximately 6 hours of operation are required to reach this temperature.

THERMOMETER CALIBRATION

After your new model has been given sufficient time to pull down to the above specified temperature range, the exterior thermometer located on the upper grill must be checked for calibration accuracy. All thermometers are carefully calibrated at the factory prior to shipping but may be vibrated out of calibration through rough handling in transit, shipping vibration, or during installation.

CALIBRATION CHECK

To check calibration, an accurate, mercury thermometer (within the temperature range of your model) must be placed inside of the cabinet on the center shelf for at least 15 minutes without any door openings. At this time, note the temperature on the exterior cabinet thermometer, quickly open the door and compare it to the interior thermometer's temperature. Whatever the difference (if any) is the amount the exterior thermometer must be adjusted.

The adjustment procedure varies depending on which thermometer is equipped with your model (see figure 5).

DIAL THERMOMETER

For a dial thermometer, carefully pry the clear plastic lens cover from the thermometer body using a slotted screwdriver. To adjust the needle, hold the center hub stationary using a small slotted screw driver and very carefully grasp and turn the needle to the desired temperature using your fingers. Replace the lens cover and recheck the calibration.

DIGITAL THERMOMETER

For a digital thermometer, note how many degrees the digital display needs to be increased or decreased. Press twice directly on the mylar display towards the right center using your finger. After pressing the first time, the display should read "cal" indicating that you are in the calibration mode and after pressing the second time, the display should read either zero or a positive number or a negative number (this number is the point of origin for calibration). If your digital display needed to be increased, you must advance the point of origin by that many degrees by pressing directly on the mylar display towards the left top. If your digital display needed to be decreased you must decrease the point of origin by
