8. Replace the sealing ring if it becomes hard, deformed, cracked, worn, pitted, or soft and sticky. The sealing ring pro-
vides a pressure tight seal between the cover and body. The sealing ring needs to be in good condition to function properly.

result in bodily injury or property damage. It is recommended that the sealing ring be replaced every two years.

Theoverpressureplugisasecondarypressurereliefvalvewhichisdesignedtorelieveexcesspressurebyreleasingfromthe
cooker cover in the event that the vent pipe becomes blocked. The overpressure plug is made of rubber, and when new, is
softandpliable.Overtime,dependingonthefrequencyandtypeofuse,rubberbecomeshardandinexible.Whenhardand
inexible,theoverpressurepluglosesitsabilitytoactasasecondarypressurereliefvalve.Itshouldbereplacedimmedi-
ately. It is recommended that the overpressure plug be replaced every two years.
 Shouldtheoverpressureplugeverbeforcedoutofthecoverduetoexcesspressurewhilecooking,itisimportanttocallthe
TestKitchenat1-800-368-2194.Do not attempt to use the released overpressure plug.
CLEANING
1. All parts of your pressure cooker, including the sealing ring and pressure regulator, are fully immersible for easy cleaning.
Whenwashingtheunit,thesealingringshouldberemovedtoalloweasycleaningoftheinsiderimofthecover.Thesealing
ring should be washed in hot, soapy water after each use.
2. To be sure the vent pipe is clear, hold the cover up to the light and look through the vent pipe. Clean it with a small brush or
pipe cleaner if it is blocked or partially blocked (Fig. N). Also clean the vent pipe nut as shown.
 3. Occasionallyremovetheairvent/coverlockinthepressurecooker
cover handle for cleaning. To remove the air vent/cover lock, place your
ngerovertheholeinthecoverhandle(Fig.N)andremovethewhite
rubber gasket from the air vent/cover lock on the underside of the cover
(Fig.O).Pushtheairvent /coverlockthroughthetopofthecoverand
wash it and the gasket in hot, soapy water. The metal shaft of the air vent/
cover lock may be cleaned with a nylon mesh pad. Clean the hole in the
cover handle with a small brush. After cleaning, reinsert the metal shaft
of the air vent /cover lock from the top side of the cover down through the
coverhandlehole(Fig.P).Placeangeroverthehandlehole(tokeepthe
coverlockfromfallingout)andturnthecoverover.Wettherubbergasket
and push onto the end of the metal shaft until it snaps into the groove on
the shaft.
4. The overpressure plug can also be removed for cleaning by pushing it
out of its opening from the top of the cover. After cleaning, reinsert it by
pushingthedomedsideoftheplug,marked“TOP”,intotheopeningfrom
the underside of the cover, until the bottom edge is fully and evenly seated
againsttheundersideofthecover(Fig.Q,page8).Whentheoverpressure
plugisproperlyinstalled,theword(TOP)willbevisibleontheoverpres-
sure plug when viewing the outside of the cover.
Special Cleaning Instructions for Aluminum Cookers:
1. Iron and other minerals in water and foods may darken the inside of your
aluminum cooker. This discoloration will not affect the food cooked in the
unit. These stains can be removed by using a solution of water and cream
oftartar.Useatablespoonofcreamoftartarforeachquartofwaterand
pourenoughsolutionintothecookertocoverthediscoloration(donotll
over⅔full).Closethecoversecurely,placethepressureregulatoronthe
vent pipe, and heat until the pressure regulator rocks gently. Remove the
cooker from the heat and allow it to stand for two to three hours. Remove
the pressure regulator and discard the contents. Scour thoroughly with a
soap impregnated steel wool pad; wash, rinse, and dry.
2. The outside surface of aluminum pressure cookers may be cleaned with
a good silver polish, if necessary. Staining may result if the cooker is
washed in the dishwasher. If food residue adheres to the pressure cooker
body,cleanwithanylonmeshpad,anesteelwoolpad,oranekitchen
