Always fully close the pressure canner.
The canner is fully closed when
the cover handles are above the body handles.
Your pressure canner has specially designed lugs on the cover and the
body which lock the cover in place when the canner is fully closed.
However, if the canner is not fully closed, the lugs cannot lock the cover
onto the body.
Therefore, it is possible that pressure could build inside the canner and
cause the cover to come off and result in bodily injury or property damage.
Always be sure the cover handles are above the body handles. Do not turn
past handle alignment.
5.
Never open the canner when it contains pressure.
The air vent/cover
lock visually indicates the state of pressure in the canner. When it is up,
there is pressure in the canner. When it is down, there is no pressure and
the canner can be opened.
If the canner is opened before all of the pressure is released, the contents
will erupt and could cause bodily injury or property damage.
6.
Replace the sealing ring and overpressure plug if they become hard,
deformed, cracked, worn, pitted, or soft and sticky. Always replace
the overpressure plug when replacing the sealing ring.
Both parts are made of rubber, and when new, are soft and pliable. Over
time, depending on the frequency and type of use, rubber becomes hard
and inflexible. Replace the sealing ring and overpressure plug at least
every 3 years.
The overpressure plug is a secondary pressure relief valve designed to
relieve excess pressure by releasing from the canner cover in the event that
the vent pipe becomes blocked.
When hard and inflexible, the overpressure plug loses its ability to act as a
secondary pressure relief valve. It should be replaced immediately.
Should the overpressure plug ever be forced out of the cover due to excess
pressure while cooking, call the Presto Consumer Service Department at
1 800 877-0441 for assistance in determining why this happened.
Do not
use the released overpressure plug.
