4. AIR VENT/COVER LOCK

The air vent/cover lock automatically vents, or exhausts air, from the canner and acts as a visual indication of

pressure in the canner. The small gasket must be in place for the air vent/cover lock to seal completely.

5. LOCKING BRACKET

The locking bracket on the inside of the canner body engages with the air vent/cover lock to prevent the cover

from being opened when there is pressure in the unit.

6. SEALING RING

The sealing ring fits into the canner cover and forms a pressure-tight seal between the cover and body during

canning and cooking.

7. OVERPRESSURE PLUG

The black, rubber overpressure plug is located in the canner cover. It will automatically pop out and release

steam in case the vent pipe becomes blocked and/or clogged and pressure cannot be released normally through

the vent pipe.

8. CANNING-COOKING RACK

The canning-cooking rack is placed in the bottom of the canner to hold jars off the bottom of the unit while

canning. When cooking, the rack is used for steaming foods. It can also be used to hold foods such as veg-

etables out of the cooking liquid which allows several foods to be cooked at the same time without an

intermingling of flavors. When it is desirable to blend flavors, do not use the canning-cooking rack. The

canning-cooking rack must always be used when canning.

REPLACEMENT PARTS

Use only genuine Presto



ordered directly from Presto; see "SERVICE AND PARTS INFORMATION" on page 33. When ordering

parts, please specify the seven digit model number found stamped on the side of the canner body.

1. Remove the sealing ring by simply pulling it from the sealing ring groove.

2. Wash the cover, body, and sealing ring with warm, sudsy water to remove any manufacturing oils. Rinse all parts with warm water

and dry.

3. Replace the sealing ring in the sealing ring groove, making certain to fit the ring under the stop tab located on the inside rim of the

cover (Fig. B).

4. The sealing ring is prelubricated. If necessary, to help make the cover easier to open and close, a very light coating of vegetable oil

may be applied to the sealing ring and underside of the body lugs (Fig. B). The cover should open and close easily when following

the instructions on page 5, step 7.

5. Check the air vent/cover lock in the canner cover to be sure the two pieces

are screwed together securely. If loose, tighten with fingers until a point

of resistance is met (finger tight). See pages 7–8.

6. Attach the dial gauge to the canner cover by first removing the nut, the

metal washer, and the white compression gasket from the threaded end

of the dial gauge. Then, turn the cover upside down. Starting from the

bottom, insert the threaded end of the dial gauge up through the hole in

the center of the cover until the metal base rests on the cover.

While holding the dial gauge in place, position the gasket (the gasket

should rest within the cover hole), the metal washer, and then the nut on

the threaded end of the gauge (Fig. C). Tighten with fingers.

Important: The dial gauge is a delicate instrument which must be handled with care. Do not

submerse cover or let gauge come in contact with any liquid. Do not store the dial gauge at tem-

peratures below freezing.

Helpful Hint: To help yourself understand the operation of the pressure canner, pour 4 cups of water

into the canner and follow the step-by-step instructions beginning with step 6 on page 5. For actual

usage of the canner, follow the complete instructions beginning on page 4 for pressure canning and

beginning on page 20 for pressure cooking.
