NEVER PRESSURIZE FRYER TO CLEAN. Leave
the lid open. Water under pressure is super heated and
will cause severe burns if it comes in contact with skin.
Never heat the cleaning solution to the boiling point. If the
cleaning solution in the cookpot starts to foam and boil
over, DO NOT TRY TO CONTAIN IT BY CLOSING
THE FRYER LID, or severe burns could result.
Do not use steel wool, other abrasive cleaners or
cleaners/sanitizers containing chlorine, bromine, iodine,
or ammonia chemicals, as these will deteriorate the
stainless steel material and shorten the life of the unit.
Make sure the inside of the cookpot, the drain valve
opening, and all parts that come in contact with the new
shortening are as dry as possible.
1. It is recommended that a high quality frying shortening
be used in the pressure fryer . Some low grade
shortenings have a high moisture content and will cause
foaming and boiling over.
2. If a solid shortening is used, it can be melted into a
liquid first, then poured into the cookpot. Attempting to
melt solid shortening in the cookpot may cause burning
or scorching of the fresh shortening.
