Leakage between the cover and body that occurs during
cooking is usually caused by shrinkage or deterioration of
the sealing ring after prolonged use. Replace the sealing ring.
Whenever you replace the sealing ring, replace the overpres-
sure plug also.
5. The formation of a small amount of moisture under the pres-
sure regulator is normal when cooking first begins. It is the
result of the temperature of the regulator being lower than the
rest of the unit.
A small amount of steam or moisture may also be visible
around the overpressure plug and air vent/cover lock as
cooking begins. It should stop when pressure begins to build
and the overpressure plug and air vent/cover lock seal. If
leakage continues, clean or replace the overpressure plug
and/or air vent/cover lock assembly. The pressure cooker will
not seal if the gasket for the air vent/cover lock is cracked.
Do not operate your pressure cooker with continual leak-
age.
If the preceding steps do not correct the problem, return
the entire unit to the Presto Factory Service Department (see
page 65).
6. To ensure continued accuracy of the Control Master
heat
control, avoid rough handling in use and storage.
7. If for any reason the pressure cooker cannot be opened, con-
tact the Consumer Service Department in Eau Claire, WI at

Any maintenance required for this product, other than normal
household care and cleaning, should be performed by the
Presto Factory Service Department (see page 65).

Your favorite recipes may be adjusted for cooking in the
pressure cooker by following the general directions in this
book for the particular type of food being cooked. Decrease
the cooking time for your recipe by
2
⁄

since pressure cooking
is much faster than ordinary cooking methods. For example,
if your ordinary cooking method requires 45 minutes, in the
pressure cooker the cooking time will be 15 minutes. Be-
cause there is very little evaporation, the amount of liquid
used should be decreased. Use about
1
⁄
2
cup more liquid than
you’ll desire in your finished dish. But, remember, there must
always be water or some other liquid in the pressure cooker to
produce the necessary steam.
Use the trivet and steamer basket when it is desirable to cook
foods out of the cooking liquid. When foods are pressure
cooked out of the liquid, flavors will not intermingle. There-
fore, it is possible to cook several foods at once, as long as
they have similar cooking times. If it is desirable to blend
flavors, do not use the steamer basket and trivet.
Many different cooking liquids can be used in a pressure
cooker. Wine, beer, bouillon, fruit juices, and of course water
all make excellent cooking liquids in the pressure cooker.
Beautiful desserts and side dishes can be prepared in the
pressure cooker, using individual or small metal molds or
glass custard cups, which are ovenproof. Fill molds

to allow for expansion of food, and fit them loosely into the
pressure cooker in the steamer basket. Do not fill the pressure
cooker over
2
⁄

full.
If a recipe says to cook 0 minutes, cook food only until the
pressure regulator begins to rock. Then cool pressure cooker
according to recipe.
