Maintenance Messages
To assure correct operation and maximum sterilizer life, the Midmark M3 provides the operator with reminders when it’s time to perform operator maintenance. After the M3 is powered ON for 7, 14 and 21 days, a message “Perform Periodic Maintenance” will be displayed. After 28 days, a “Perform Monthly Maintenance” message will be displayed. Refer to the appropriate maintenance instructions in this manual. The maintenance reminders are removed from the display when a cycle is started. If power is turned OFF, the timer will reset, initiating a new cycle of messages.
Daily Care
- Clean External Surfaces / Tray and Chamber
A.) Wash unit according to your facility’s procedure for clinical contact surfaces noting the following:
(Use only quaternary disinfectants to disinfect unit. Staining, pitting, discoloration, or softening could occur if phenolic, iodophor, or glutaraldehyde-based disinfectant is used on plastic surfaces of the unit. Also, use of alcohol or aerosol spray cleaner / disinfectant containing substantial amounts of alcohol in the formula can damage the faceplate.)
B.) Wring excess solution from cloth.
C.) Using soft cloth, wipe all external surfaces.
D.) Follow the instructions provided with the cleaner / disinfectant used regarding rinsing and drying of external surfaces.
- Clean Chamber Filter
Check that the chamber filter is free of debris and properly positioned in the hole at the back of the sterilizer chamber. If the filter is blocked by debris follow the procedures under “Monthly Maintenance” to remove and clean the filter.
- Clean Door Gasket / Mating Surface
A.) Wash with a damp cloth.
B.) Inspect gasket for damage.
C.) Replace gasket if necessary.
Periodic Maintenance
- Drain/Fill Reservoir As Needed
A. Remove drain hose from storage location.
B. Place open-end of drain hose into container or sink.
C. Connect adapter-end of drain hose to coupling as shown.
D. Once water has drained, press release lever and remove hose. E. Return drain hose to storage location.
F. Refill reservoir with distilled water.
Empty/Clean External Condensing Tank (As Needed)
Note: This process is not necessary if the sterilizer is connected to a direct-to-drain thermal reduction system.
A. Empty water from tank. (Do not reuse water!)
B.) Clean tank with diluted bleach solution (1/4 cup bleach : 1 gallon water) and a brush.
C.) Rinse tank thoroughly.
D.) Refill tank to minimum water level indicator line.
Monthly Maintenance
- Remove and Clean Filter
Wash with mild soap solution to remove debris. Rinse with distilled water. (Use a stiff brush to scrub, or place in ultrasonic cleaner if necessary.)
- Clean Condensing Tank Level Sensors
Note: This process is not necessary if the sterilizer is connected to a direct-to-drain thermal reduction system.
Clean the two sensors with mild soap solution, then wipe dry.
Extended Use Maintenance
The M3 is designed and tested to provide exceptional reliability throughout its service life. However, like all electro-mechanical devices it is 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 after 8 years or 20,000 cycles of use, whichever comes first. After 8 years or 20,000 cycles of use an annual inspection by a Midmark Authorized Service Provider is recommended.
