Replace the retort seal periodically. If the retort is not sealed properly, pressure may not rise or other problems may
occur.
1. Open the retort lid and pull out the worn retort seal.
2. Clean the seal groove using a cloth or paper towel. If paraffin or other foreign matter is attached, use a paraffin
scraper as necessary.
3. Prepare the new retort seal. First, check the installation direction. The wider side should be facing the back of the
groove in a side view of the retort seal.
4. Determine the positions of a and b by making sure the right and left are even, and then push the seal at a and b
into the seal groove. Push in the inner side first.
Next, insert the seal at c and d into the groove by making sure the top and bottom are even, and then push in the
rest toward the corners.
5. Trace the surface of the retort seal with a finger and push in any part that is not inserted properly.
