Routine Care Guide
To ensure proper operation and maximum sterilizer life, carefully follow all instructions for routine care.
One of the most important ways to prevent problems with your sterilizer is to only use distilled water, or water that meets the referenced water purity specifications (see Water Purity Specifications). DO NOT USE TAP WATER. The sterilizer operates with high water temperatures and minerals dissolved in water can form mineral deposits that can prevent valves from opening or closing properly and lead to corrosion in the chamber and tubing.
Routine care reminders will be displayed on the screen at the appropriate intervals to assist the operator.
Note
Following each cleaning, visually inspect to ensure no material remains. Re-clean if necessary.
This screen has three main tabs: Daily, Weekly and Monthly. Each of these tabs will show it’s current status of up to date, due or overdue with the corresponding color bar. Routine care that is due or overdue will have a Run button that steps through the required care.
Replace Items – The “Replace Items” button allows users to track consumable parts, which are stored in history and can be exported. There are also installation help screens for the user to follow.
Routine Care History – The “Routine Care History” button allows users to view the daily, weekly, and monthly care event history and export these records.

Extended Use Care
The M9® and M11® Steam Sterilizers 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 25,000 cycles, which ever comes first. After 10 years or 25,000 cycles of use, an annual inspection by a Midmark Authorized Service Provider is recommended. Software support may not be available after 10 years.
