This manual provides instructions for the Avantco Panini/Sandwich Grill. This equipment is intended for commercial use only and must be connected to a grounded 120V power outlet. Before first use, you must remove the protective food-safe oil coating from the plates. Always disconnect power and allow the machine to cool before cleaning.

Operating Instructions
- Ensure the power cord is connected to a proper 120V, 60Hz source.
- Verify the power indicator light is on.
- Set the desired temperature. The warm-up time is approximately 20 minutes. The heating indicator will cycle on and off as the grill maintains the set temperature.
- Once the set temperature is reached, lift the top grill using the black handle.
- Lightly grease the grill plates with vegetable oil.
- Place food on the grill and lightly press the handle down. Excess oil will collect in the grease tray.
- Remove food when cooked and turn off the machine when finished.
Instructions for First Time Use
To protect the plates during transport, a layer of food-safe oil was applied. This must be removed before use:
- Preheat the grill until the oil liquefies.
- Carefully wipe away the melted oil with a clean, soft cloth.
- Once all oil is removed, the grill is ready for use.
Cleaning and Maintenance
- Daily Check: Visually inspect for damage or frayed power cords before every use. Ensure the machine is on a level surface.
- Cleaning: Disconnect the machine and allow it to cool completely. Use a damp towel with a non-corrosive cleaner. Do not immerse the unit in water or spray water onto the grills.
- Storage: Store in a dry, clean area when not in use.
Troubleshooting and Hinge Adjustments
If the grill plates do not heat, the temperature cannot be controlled, or there is no power, contact a qualified technician. Do not use the machine if these issues occur.

Hinge Adjustment: If the hinge is too tight or too loose:
- Open the back cover using a Phillips head screwdriver.
- Use an Allen wrench to adjust the tightness until the lid feels natural to open and close.
- Add food-safe grease to the hinge while moving the top shell to lubricate it.
- Close the back cover.
