will chill to the setpoint temperature more quickly and
efficiently with empty pans in the well.

2. Move the Power I/O (on/off) Switch to the “I” (on) position
(located on the control panel).

• The digital temperature controller will energize and

“ON” will appear on the display, followed by the current
temperature of the unit.

• The symbol on the display will illuminate to show

the condensing unit is active and chilling the well.

NOTE: The unit is pre-set at the factory to a setpoint temperature

of 32°F (0°C). If ambient conditions require adjustment
to the setpoint temperature, refer to the “Changing the
Setpoint Temperature” in this section.

3. Allow the unit approximately 60 minutes to reach the
setpoint temperature before loading pre-chilled food
product.

4. Verify on the display that the unit has reached the proper
setpoint temperature, and replace the empty pans in the
well with pans that are loaded with pre-chilled food product.

• Always use a food pan. Do not place food directly into

the refrigerated well.

• Stir thick food items frequently to keep food chilled

uniformly.
