the gasket, call customer service to order a gasket.
2. Clean the gasket lip with a clean, damp cloth.
3. Allow the lip to dry completely.
4. Peel back a few inches of the tape on the back of the gasket.
5. Start applying the gasket at one corner of the spare parts box.
6. Continue applying the gasket while peeling the tape off the back of the gasket.
Note: On spare parts box corners, fold the tape at a 45° angle and press the tape
firmly to make it as flush as possible.
7. After applying the gasket, cut off any excess gasket.
