2.2 Power Connection
Connect the power cord securely into a proper, grounded electrical receptacle. Ensure the power supply matches the unit's requirements.
2.3 Initial Power On and Warm-Up
Switch the unit to the 'ON' position. The display will light up. Allow approximately 30 minutes for the heaters to reach their operating temperature. During this warm-up period, the unit will display current temperatures for the upper and lower shelves.

3. Operating Instructions
3.1 Applying Pan Lids
When holding grilled products, install pan lids to the Extended Holding Bin (EHB). Lift the lid gate and slide in the pan lid, ensuring it clears the EHB's lid gate. For fried products, do not install pan lids. Use a standard pan and insert it in place. For non-fried products, place a trivet inside the standard pan before inserting.

3.2 Timer Bar Functions
The timer bar indicates the status of each pan. Yellow arrows pointing up indicate the upper zone, while blue arrows pointing down indicate the lower zone. Press the ZONE button when your pan is active; the LED light will turn GREEN for a primary batch. If more than one pan is active, pressing the second ZONE button will turn YELLOW to GREEN, indicating it is now the primary batch. When the active product from the primary pan is empty or expired, press the ZONE button to deactivate the zone; the LED will turn GREEN.
