4qt TriZone® Air Fryer 35106

bella TriZone Air Fryer 35106

The bella 4QT TriZone® Air Fryer is a countertop cooking appliance with a removable 4-quart basket that can be used as one large cooking area or divided into two independently controlled zones. It provides six cooking functions: Air Fry, Roast, Broil, Bake, Reheat, and Dehydrate.

The air fryer includes a removable basket divider, two crisping trays, and a digital touchscreen control panel. With the divider removed, the entire basket operates as one cooking zone. When the divider is installed, the left and right sections can use different cooking functions, temperatures, and times.

Dual Mode allows two foods to be prepared simultaneously with separate settings. The SYNC TIME function can coordinate the programmed cooking cycles so both zones finish together.

The six cooking presets provide adjustable temperature and time settings, with a maximum cooking temperature of 450°F for applicable functions. The Dehydrate function offers lower temperatures and longer cooking times for drying herbs, fruits, and vegetables.

These instructions cover basket assembly, touchscreen controls, TriZone cooking, Dual Mode, Single Zone operation, SYNC TIME, cooking presets, recommended temperatures, food preparation, cleaning, storage, safety, and warranty service.

Frequently Asked Questions

How do I use the bella 4qt TriZone Air Fryer?

Place the air fryer on a flat, heat-resistant surface and prepare the basket. Remove the divider for full-basket TriZone cooking or install it for Dual Mode or Single Zone operation. Add food without filling the basket more than two-thirds full, insert it securely, and press POWER. Select a cooking preset, adjust temperature and time, then press START/STOP.

What are the six cooking functions on the bella TriZone Air Fryer?

The six functions are AIR FRY, ROAST, BROIL, BAKE, REHEAT, and DEHYDRATE. Each has a default cooking temperature and time, with adjustment ranges depending on the selected function.

How do I use Dual Mode on the bella TriZone Air Fryer?

Install the basket divider and place the foods in the left and right sections. Press POWER, select DUAL MODE, then program each zone using LEFT or RIGHT. Choose the cooking preset and adjust time and temperature for each side. Press START/STOP to begin cooking.

How does SYNC TIME work on the bella TriZone Air Fryer?

SYNC TIME coordinates the cooking cycles so the left and right zones finish together. Both zones must be programmed before selecting SYNC TIME. The display may show HOLD while the appliance synchronizes the cooking periods. SYNC TIME cannot be activated after cooking begins.

What is the maximum cooking capacity of the bella 4qt TriZone Air Fryer?

The basket has a capacity of four quarts, with a recommended maximum food weight of 3.3 lb. The instructions also state that the basket should never be filled more than two-thirds full to maintain proper cooking and air circulation.

What temperature does the bella TriZone Air Fryer use?

The temperature depends on the selected program. AIR FRY defaults to 400°F, ROAST to 400°F, BROIL to 450°F, BAKE to 350°F, REHEAT to 250°F, and DEHYDRATE to 130°F. Temperature adjustments use 5°F increments within each function’s supported range.

How do I clean the bella TriZone Air Fryer?

Turn off and unplug the appliance, then allow it to cool completely. Remove the cooking basket, crisping trays, and divider. Wash these components in hot, soapy water and dry thoroughly. Wipe the air fryer body using a soft, non-abrasive, damp cloth. Do not use metal utensils or abrasive cleaners that may damage the ceramic coating.

Why is my bella TriZone Air Fryer not working?

The air fryer will not operate unless the cooking basket is fully closed. Check that the basket is inserted correctly. An overloaded electrical circuit may also interfere with operation. If the appliance malfunctions, remove the basket, unplug it, and stop using it. Contact Customer Service or qualified repair personnel for assistance.
