Components:
- Main Unit: Houses the heating element and motor.
- Removable Popcorn Holder: A transparent container that collects the popped corn and can be detached for serving.
- Measuring Lid: Used to measure the correct amount of popcorn kernels and can also be used to melt butter.
3. Setup
- Unpacking: Carefully remove all packaging materials and inspect the popcorn maker for any damage.
- Initial Cleaning: Before first use, wipe the exterior of the main unit with a damp cloth. Wash the removable popcorn holder and measuring lid with warm, soapy water. Rinse thoroughly and dry completely.
- Placement: Place the popcorn maker on a stable, flat, heat-resistant surface, away from walls and cabinets to allow for proper ventilation. Ensure the power cord is not obstructed.
4. Operating Instructions
Follow these steps to prepare popcorn:
- Measure Kernels: Use the provided measuring lid to measure one full portion of popcorn kernels. Do not overfill or underfill.
- Add Kernels: Remove the measuring lid and pour the measured popcorn kernels into the popping chamber of the main unit.
- Position Holder: Place the removable popcorn holder securely onto the main unit. Ensure it is properly seated to collect the popped corn.
- Melt Butter (Optional): If desired, place butter in the measuring lid and position the lid back onto the popcorn holder. The heat from the popping process will melt the butter.
- Start Popping: Plug the appliance into a 127V electrical outlet. The popcorn maker will begin to heat up and pop the kernels. No oil is required for popping.
- Wait for Completion: Popcorn will begin to emerge from the popping chamber into the removable holder. Allow the machine to operate until popping stops, typically a few minutes.
- Serve: Once popping has ceased, unplug the appliance. Carefully remove the popcorn holder (it may be hot) and pour the popcorn into a serving bowl. Add melted butter, salt, or other seasonings as desired.
- Cool Down: Allow the appliance to cool completely before cleaning or storing.
