CAUTION!

 To prevent burns, avoid touching the food warmer liner and use a hot pad or paper towel if removing hot jar from 

food warmer base. 

How to Use in a Vehicle

1.  Insert a closed wide-mouth, pint-size jar of precooked food into food warmer base. Never place food directly in the food warmer 

liner (Fig. A, page 2). Twist food warmer cover onto base until secure. Always leave Mason jar lid and band securely fastened to 

jar when vehicle is in motion to prevent spilling. 

Note:

 Pack a hot pad and/or paper towels for use in step 4.

2.  Plug into a vehicle with a 110/120 VAC power source rated for 0.5 amperes or more. The power light will illuminate and the unit 

will begin heating. Heating times will vary depending on initial food temperature, amount of food, and type of food. For food 

safety, the USDA recommends heating leftovers to 165°F. This may take 3 hours or more. Stir food before consuming. 

3.  Once food is thoroughly heated, unplug unit and remove food warmer cover. 
4.  In order to remove the jar band and lid, it will be necessary to remove the jar from the food warmer base. 

CAUTION!

 The jar, band, lid, and food warmer liner will be very hot. To prevent burns, use a hot pad or paper towels to 

carefully lift hot jar out of base and to remove band and lid. 

5.  Stir jar contents thoroughly and enjoy.

Care, Cleaning, and Storage

1.  Always unplug and allow the food warmer and Mason jar to cool before cleaning. 
2.  Wash the Mason jar, lid, band, and food warmer cover in the dishwasher or in warm, soapy water. Rinse and dry. If washing in 

the dishwasher, place the cover on the rack farthest from the heating element.

3.  Wipe the food warmer base with a damp, soapy cloth. 

CAUTION!

 To prevent electrical shock and damage to the food warmer, never immerse the food warmer base in water or any 

other liquid. 
If necessary, gently scrub the surface with a nylon mesh pad, such as a Scotch-Brite* Multi-Purpose Scrub Sponge or Scotch-

Brite* Dobie* Cleaning Pad. Do not use steel wool or abrasive cleaners. 

4.  For storage, wrap the cord around the bottom of the base (Fig. A, page 2).
