Extended Use Maintenance
The M9/M9D and M11/M11D are designed and tested to provide exceptional
reliability throughout their service life. However, like all electro-mechanical
devices they are subject to wear and degradation with use.
To ensure the integrity, performance, and safety of all major components it
is the responsibility of the user to have the sterilizer performance / operation
verified by a Midmark Authorized Service Provider at least every 10 years or
10,000 cycles, whichever comes first. After 10 years or 10,000 cycles of use, an
annual inspection by a Midmark Authorized Service Provider is recommended.
