Reversing The Lid Gasket - Henny Penny 680 KFC Service Manual

The gray rubber gasket surrounding the inside of the lid is
designed to be reversed. HENNY PENNY RECOMMENDS
THAT THIS BE DONE EVERY 90 DAYS.
Because of heat expansion and the pressure used for the cook-
ing process, the gasket is constantly under extreme stress.
Reversing the lid gasket every 90 days will help to assure that
the fryer will not lose pressure through leakage.
1. Put the lid in the upright position, as previously described.
2. Using a thin blade screwdriver, pry out the gasket at the
corners. Remove the gasket.
Check the gasket for any tears or nicks. If the gasket
is damaged it needs to be replaced.
Be careful that the lid doesn't fall down while it is in
the upright position, or serious injury could result.
3. Clean the gasket and gasket seat with hot water.
4. Rotate the gasket with the opposite side facing out.
Begin the installation by installing the four corners of
the lid gasket, and smoothing the gasket into place from
the corners.
