cleaning or servicing this pressure fryer.

Shortening under pressure can be very hazardous unless handled
properly:

DO NOT attempt to operate this fryer without the LID O-RING and
COLLECTOR O-RING properly installed.

Do not operate this fryer if either of the LID O-RING or
COLLECTOR O-RING are damaged. A damaged O-ring will lead
to shortening leaks and/or spraying shortening.

Be sure the LID is seated in the frypot and the OPERATING
LEVER is turned fully COUNTERCLOCKWISE before starting a
