♦ Mold can form only in the presence of air. Therefore, jars are not sealed if mold is present. Discard contents.
♦ The black deposit sometimes found on the underside of a lid is caused by tannins in the food or hydrogen sulfide which is liberated
from the food by the heat of processing. This does not indicate spoilage.
♦ The loss of color from beets during canning is usually due to the variety of beets used. Two varieties that retain color well are Ruby
Queen and Detroit Red. To reduce bleeding of color, precook beets with entire root and 1 to 2 inches of stem. Remove stem and root
after precooking.

CARE AND MAINTENANCE
Canner Body
• It is normal for the inside of the canner to discolor. This discoloration, which is not harmful, is a result of the various minerals in water
and foods interacting with the aluminum. To remove this discoloration, use a solution of 1 tablespoon cream of tartar for every 1 quart
of water. Pour enough solution into the canner to cover the discoloration, making sure the canner is not lled more than ⅔ full. Close
the cover securely, place the pressure regulator on the vent pipe, and heat until the pressure regulator begins to rock. Remove canner
from heat; allow to cool until air/vent cover locks drops. Remove regulator, open canner, and empty contents. Scour thoroughly with
a steel wool soap pad; wash, rinse, and thoroughly dry.
• Pitting is caused by the interaction of aluminum with other metals in the presence of moisture. To minimize pitting, wash, rinse, and
dry the canner body thoroughly after every use. Additionally, at least once a year, scour the inside of the canner body with an abrasive
cleanser, such as Cameo* Aluminum & Stainless Steel Cleaner. Always store the canner in a dry area.
• Do not leave an empty canner on a heated burner or allow canner to boil dry. This can cause damage to the canner bottom and/or stovetop.
• Do not strike the rim of the canner body with any metal utensil as this will cause nicks which may damage the rim and allow steam
to escape.
• Do not pour water into a dry, overheated canner as this may crack the metal.
• If the canner body or cover handles become loose, tighten them with a screwdriver.
Pressure Dial Gauge
• The pressure dial gauge is a delicate instrument and must be handled with care. Do not submerge the pressure dial gauge, allow it to
come into contact with liquid, or subject it to freezing temperatures.
• The pressure dial gauge needs to be checked for accuracy prior to each canning season and if any of the following conditions exist:
cover has been submerged in water or dropped, parts are rusty, pointer is not in the “0” block, or if you believe the gauge may not be
accurate. The gauge can usually be checked at your local county extension ofce. If you are unable to have your gauge checked locally,
carefully remove it, wrap securely, and send to the Presto Consumer Service Department. See “SERVICE AND PARTS INFORMATION”
on page 35. An accurate gauge is necessary to help prevent food spoilage and possible food poisoning.
Sealing Ring and Overpressure Plug
• Each time the canner is washed, remove the sealing ring and wash in warm, soapy water, rinse, dry, and replace in cover.
• The sealing ring and overpressure plug should be replaced at least every three years or sooner if sealing ring becomes hard, deformed,
cracked, worn, pitted, or if the canner becomes difcult to open or close. Failure to replace the sealing ring and overpressure plug could
result in bodily injury or property damage. Use only genuine Presto
®
replacement parts.
• Exposure of the sealing ring and overpressure plug to direct high heat, such as a hot burner or stovetop, will cause the sealing ring and
overpressure plug to deteriorate rapidly. If this occurs, replace these parts.
• Before replacing the sealing ring, clean the sealing ring groove with a brush, if necessary.
• To clean or replace the overpressure plug, push it out of its opening from the top of the cover. After cleaning, or when replacing, re-
insert the plug by pushing the domed side of the plug into the opening from the underside of the cover, until the bottom edge is fully
and evenly seated against the underside of the cover. When properly installed, the word (TOP) will be visible on the overpressure plug
when viewed from the outside of the cover (Fig. M).
• If the overpressure plug is ever forced out of the cover due to excess pressure
while cooking or canning, it is important to call the Presto Customer Service
Department at 1-800-877-0441 for assistance in determining why this happened.
Do not attempt to use the released overpressure plug.
