This video is an overview of monthly maintenance
for your autoclave.
However always refer to the appropriate technical
documentation for the complete list of instructions,
safety alerts and sequence of procedures before
conducting any service or maintenance operations.
Every 28 days the autoclave automatically
displays a "perform monthly maintenance" message.
This is a more thorough cleaning of the unit
and involves multiple steps.
Clean the chamber and plumbing: with a cool
chamber drain the autoclaves reservoir and
refill with distilled water.
Add one ounce of speedclean autoclave cleaner
directly to the cool chamber.
This is where you load your instruments for
sterilization.
Run one pouches cycle, but push the stop button
when the drying cycle begins.
It's not necessary for the dry cycle to run
during this maintenance.
Drain the reservoir again and refill a second
time with clean distilled water for the rinse
cycle.
Rinse by running one unwrapped cycle.
Push the stop button when the drying cycle
begins.
After the cycle has completed, drain and fill
the reservoir with clean distilled water.
Then allow the sterilizer to cool.
Remove the trays and tray rack, and wipe with
a damp cloth.
Next remove and clean filters.
Remove filters by pulling upward and twisting
slightly.
Filter should be cleaned by washing with a
mild soap and distilled water solution.
Use a small stiff brush or an ultrasonic cleaner
to remove stubborn deposits.
After cleaning rinse the filters with distilled
water and set them aside.
Wipe the inside of the autoclave chamber being
careful not to damage the heating element,
steam temperature probe, or water level sensor.
Reinsert the filters into the appropriate
holes by pushing downward while twisting slightly.
Reinstall the tray rack.
Next, remove and clean the door and door dam
gaskets.
Remove the door dam gasket and then the gasket
ring from the unit.
Clean gaskets and ring with speedclean, distilled
water and a soft brush.
Inspect the gaskets for damage, shrinking
or swelling.
Replace the gasket if damage is apparent.
Press the door gasket ring into the channel
and the door gasket and place the door gasket
back into the door.
The next part of the required monthly maintenance
involves verifying proper operation of the
pressure relief valve.
Since high pressure and temperature steam
will be vented from under the autoclave during
this track place a roll towel around the bottom
of the autoclave to act as a steam barrier.
Press the unwrap cycle and then start.
Monitor the display and wait for the pressure
to reach 20 PSI.
When 20 PSI is reached pull upward firmly
on the relief valve lever on top of the autoclave
capping and hold it open for three seconds.
Steam should discharge freely from beneath
the rear of the unit.
Release the lever quickly and verify that
the valve has closed properly, by noting that
steam has stopped escaping.
If the unit is still releasing steam pull
up on the valve lever again and release it
quickly so the valve snaps back into position.
Repeat this if necessary to make sure the
valve is seated correctly.
Press STOP to cancel the cycle preventing
the unit from overheating.
Allow the chamber to cool.
If excessive force is required to open the
valve or if it will not reseat properly, contact
your Midmark authorized dealer.
When the maintenance is complete the "perform
monthly maintenance" message will go away
during your next sterilization cycle.
M9 and M11's are designed and tested to provide
exceptional reliability throughout their service
life.
To ensure integrity, performance and safety
of all major components, it is the responsibility
of the user to have the sterilizer performance
and operation verified by Midmark Authorized
Service Provider at least every 10 years or
10,000 cycles, whichever comes first.
For more detailed information about maintaining
your autoclave, please refer to the M9/M11
installation and operation manual.
