educe Pressure
WARNING: Steam escaping from the
vent pipe can scald or burn you and
t
he pressure regulator weight may be
hot. Protect your hand with a pot
holder or mitt.
When cooking is completed and
heat is off, reduce pressure as follows:
• After most normal cooking, permit
cooker to cool until steam pressure
gauge reads zero.
• After cooking soup, cereals, or any
food that might boil over in the
pans, turn heat off and permit
cooker to cool.
• After canning in glass jars, turn
heat off and permit cooker to cool
gradually until the steam gauge
drops to zero. Remove the selective
pressure regulator weight slowly
and do not release steam pressure
too rapidly as liquid will be drawn
from jars.
• After canning in tin cans, turn heat
off and release pressure as quickly
as possible by removing the
selective pressure regulator weight
with fork or hot pad.
Do not put cold cloths or water on
the cooker to hasten cooling. This
may crack the aluminum.
Do not move the pressure cooker
until the pressure is completely
reduced.
Opening Cooker Safely
CAUTION: Never loosen wing nuts
until the steam pressure gauge
registers zero, and you have allowed
any remaining pressure to escape by
carefully removing the selective
pressure regulator weight.
Remove cover, raising farthest
edge first to protect face and arms
from steam.
When the pressure regulator
weight is left on, a vacuum may
form inside the cooker making the
cover difficult to remove. To avoid a
vacuum, which will cause the cover
to be drawn to the bottom very
tightly, you must remove the pres-
sure regulator weight from the vent
p
ipe as soon as the pressure gauge
indicator reaches zero P.S.I. and then
remove the cover. The longer you
wait without removing the pressure
regulator weight, the more vacuum
w
ill form, pulling the cover tighter
and tighter to the bottom.
Another reason that a cover sticks
to the bottom is that the metal-to-
metal seal has been permitted to
build up a coating of foreign material
such as dried grease, lubricating oil,
etc. Please refer to page 7 under the
section “Metal-to-Metal Seal,
Cleaning and Maintenance” for
complete instructions.
Removing a “Stuck” Cover
(due to a vacuum)
In the event that a vacuum forms,
use a large standard screwdriver to
pry the top loose. Place the end of
the screwdriver at an angle between
the cover and bottom near a wing
nut assembly. Do not go straight in
with the screwdriver or you will
damage the metal-to-metal seal.
Gently pry upward using the screw-
driver as a lever. Continue to pry
upward at each wing nut assembly
area uniformly so that the cover is
raised evenly. In most cases, the
cover should come off rather quickly.
If you need further assistance,
please call the factory.
