Sealing Ring
The sealing ring installed on the underside of the lid creates an air-tight seal
between the lid and the cooker.
Remove the sealing ring by pulling it gently off of the circular, stainless steel
sealing rack attached to the underside of the cooker lid.
Clean and inspect the sealing ring for deformation or damage after each use.
Reinstall by gently pressing the sealing ring over the sealing ring rack. Ensure
that the sealing ring rack sits snugly within the groove in the sealing ring.
Notes: Two sealing rings are included with the cooker. Use one for sweet dishes
and one for savory dishes.
Only one sealing ring should be installed in the lid when using the cooker.
Replace the sealing ring(s) every 12 months or when the sealing ring
becomes deformed or damaged.

Sealing rings may stretch over time. Do not use a stretched or damaged sealing ring.
If puckering occurs, replace sealing ring.
