Introduction to Parts
1. PRESSURE DIAL GAUGE
Thepressuredialgaugeregisterspressureinbothpounds(outerscale)andmetricmeasure(innerscale).The
pointermovesaroundthedialindicatingthepressurewithintheunit.Beforeeachcanningseason,checkthe
pressure dial gauge for accuracy.
2. PRESSURE REGULATOR
The pressure regulator is a solid one-piece unit. Accurate pressure readings are registered on the pressure
dial gauge and can be controlled and maintained by adjusting heat settings.
3. VENT PIPE
Thepressureregulatortsovertheventpipeandallowsexcesspressuretobereleased.
4. AUTOMATIC AIR VENT
Theautomaticairvent,locatedinthecenteroftheCannercover,doesthefollowing:(1)Automatically
ventsorexhaustsairfromtheCanner;(2)Automaticallyreleasesexcesssteamincasetheventpipebecomes
cloggedandpressurecannotreleasenormally:(3)Actsasananti-vacuumvalve,preventingthelossofjuices
fromfoodafterpressureiscompletelyreduced;(4)Actsasavisualindicationofpressureinthecanner.
5. SEALING RING
ThesealingringtsintotheCannercoverandformsapressure-tightsealbetweenthecoverandbodydur-
ing canning and cooking.
6. CANNING RACK
ThecanningrackisplacedinthebottomoftheCannertoholdjarsoffthebottomoftheunitwhilecanning.
JarsmaybreakduringthecanningprocessifplacesonthebottomoftheCanner.Thecanningrackshould
always be used when canning.

totherecommendedlevel.Allow½-inchheadspaceforfruits.Allvegetables,meat,poultry,andseafoodrequire1-inchheadspace
duetoexpansionduringprocessing.Workoutairbubbleswithacleanspatula.Wipesealingedgecleanwithadampcloth.
 Adjustlidsandbandsaccordingtoclosuremanufacturer’sdirections.
4. PlaceCanneronalevelburner.Useonatiltedburnermayinterferewiththeoperationofthepressureregulator.Placethreequartsof
boilingwater,canningrack,andjarsinroomtemperatureCanner.Pouringwaterintoadry,overheatedCannermaycrackthemetal.
TopreventwaterstainsinCanneroronjars,add2tablespoonswhitevinegartowaterinCanner.Placejarsoncanningrack.Always
