Components
Your THERMOS FUNTAINER food jar consists of the following main components:
- Stainless Steel Food Jar Body: The primary insulated container.
- Lid: A secure, twist-on lid designed to seal the container and maintain temperature.
Setup and Initial Preparation
- Initial Cleaning: Before first use, wash all parts of the food jar and lid with warm, soapy water. Rinse thoroughly and dry completely.
- Pre-heating for Hot Food: To maximize heat retention, pre-heat the interior of the food jar. Fill the jar with hot tap water (not boiling) and let it stand for 5-10 minutes. Empty the water just before filling with hot food.
- Pre-chilling for Cold Food: To maximize cold retention, pre-chill the interior of the food jar. Fill the jar with cold tap water or ice water and let it stand for 5-10 minutes. Empty the water just before filling with cold food.
Operating Instructions
Follow these steps to use your THERMOS FUNTAINER food jar:
- Prepare Food: Ensure your food is at the desired temperature (hot or cold) before placing it in the jar. For best results with hot food, ensure it is heated thoroughly.
- Fill the Jar: Place your prepared food into the pre-heated or pre-chilled stainless steel food jar. The wide mouth design makes it easy to fill.
- Secure the Lid: Twist the lid firmly onto the food jar until it is securely sealed. This is crucial for maintaining the internal temperature and preventing leaks.
- Temperature Retention: The food jar is designed to keep food hot for up to 5 hours and cold for up to 7 hours. The exterior remains cool to the touch even with hot contents.
