III. Operating Instructions
A. Startup
Open the front panel for access to the power switch—located on the front of the control
box—and turn the switch on. Allow the unit to pull down prior to loading it with food
products.
IMPORTANT
At startup, there is a 2 1/2 minute normal delay before the compressor starts.
B. Cabinet Temperature
1. Current Temperature Display
• The cabinet temperature is displayed on the control panel. The display default is °F, but
it can be changed to read °C. To change, see "D. Temperature Display Scale (°F or °C)".
• The cabinet temperature is updated every 20 seconds.
2. Temperature Setpoint
The temperature setpoint is the value for the average cabinet temperature. For example,
setpoint = 36°F, compressor on at 39°F, compressor off at 33°F. If necessary, adjust the
setpoint temperature as follows:
1) Press and hold the up/down arrows simultaneously for 3 seconds. The current setpoint
temperature will be displayed.
2) To change the setpoint, press the up/down arrows until the desired value is displayed.
The cabinet temperature is adjustable between 36°F and 50°F (2.2°C and 10°C). The
factory default is 36°F (2.2°C).
3) Press "ENTER" to set the value and view the next setting. If no change in the value
is desired, press "ENTER", and the next setting will be displayed. At the end of the
sequence, press "ENTER", and the unit will return to normal display mode.
Important Note:
For the change to take effect, you must cycle through the menu until
you return to the normal display.
