What refrigerant does this refrigerator use and why is it important?

The refrigerator uses either R-600a or R-134a as a refrigerant, which you can verify by checking the compressor label on the rear of the appliance or the rating label inside the fridge (Page 6). If your product contains flammable gas refrigerant R-600a or R-134a, you should contact your local authority regarding safe disposal of this product (Page 6).
