- Turn on the unit using the power switch, typically located near the compressor compartment.
- Allow the unit to run for several hours (e.g., 4-6 hours) to reach its operating temperature before loading with food products.
4.2 Temperature Control
The unit features precise digital temperature controls, visible on the front panel.
- The digital display shows the current internal temperature.
- Refer to the control panel instructions (usually located near the display) for adjusting the set temperature.

4.3 Food Pan Usage and Cutting Board
The prep table comes standard with (6) 1/3 size food pans and a reversible full-length cutting board.
- Place food pans into the top well. The intuitive open well design accommodates 1/3, 1/2, or full-size pans without adapter bars.
- Ensure food products in pans do not exceed the top edge of the pan to allow proper lid closure and temperature maintenance.
- The cutting board provides a sanitary surface for food preparation. It is reversible and removable for cleaning.
