9.4 Cleaning the Air Jet
(Located in the water reservoir.)
A dirty air jet is the number one cause of failed spore tests
The elimination of air from the sterilization chamber during heat up is
critical to the proper operation of the autoclave. Failure of the air
removal system will be responsible for incomplete sterilization, indicator
strips that do not turn, failed spore tests and aborted sterilization cycles.
A clogged air jet will result in receiving the error message “Low Heat”.
The air jet consists of a small orifice with a clean out wire inserted in it
(wire is permanently installed and will not come out). It is required that
the air jet be cleaned once per week or more often if necessary, to remove
any accumulated dirt and debris.
It is preferred to clean the air jet when the unit is running a cycle and
under pressure. Any loosened debris will be blown away, however, it can
be done while the unit is idle.
1. Remove the water reservoir cover.
2. Clean the hole of the jet by manipulating the air trap wire back and forth
10 times.
It is important to clean the hole of the air trap, as described at point 2
before starting operation of the autoclave, for the first time.
