This summary provides essential operating and maintenance instructions for the Sanyo MAC 1200 autoclave, a tabletop steam sterilizer commonly used in medical and dental environments JustAnswer Core Operating Specifications
The MAC 1200 utilizes saturated steam to achieve sterilization. Sterilization Temperature: Typically ranges between 115°C and 135°C Standard Cycle: A common setting for effective sterilization is 121°C at 15 psi for approximately 15 to 20 minutes Media Requirements: Always use distilled water to prevent mineral buildup and damage to internal valves.
A built-in digital display provides real-time monitoring of sterilization temperature and remaining time. TRH Services Proper Loading Techniques
Efficient steam circulation is critical for total sterilization. TRH Services Avoid Overloading:
Do not pack the chamber too tightly; steam must reach every surface.
Place sterilization pouches on their edges or with the paper side down to facilitate drying and steam penetration. Materials: sanyo mac 1200 autoclave manual
Most plastic labware and unwrapped instruments are compatible, but never autoclave paper directly as it can cause water damage or combustion. JustAnswer
-liter capacities (depending on the specific MLS-series variant). sterilizers.com Operational Instructions Preparation
: Ensure the chamber is clean and the drain strainer at the bottom is free of debris. Water Level : Fill the reservoir with distilled water
only. Use a dipstick to ensure the level is between the minimum and maximum lines; minerals in tap water can damage the heating coils.
Place items in stainless steel baskets. Do not overload or allow items to touch the chamber walls. For pouches, ensure the paper side faces up to allow effective steam penetration and evaporation. Never open while pressurized
: Close the lid and hand-tighten the door to secure the seal without damaging the gasket. Cycle Selection : Select the sterilization time (ranging from
hours) and temperature based on the load type (e.g., glassware vs. liquid waste). Maintenance & Troubleshooting
: Inspect and wipe the door gasket with a mild detergent to prevent steam leaks.
: Drain the water reservoir completely and refill with fresh distilled water to prevent mineral buildup. Common Issues Incomplete Sterilization
: Often caused by clogged filters, insufficient water levels, or overloading the chamber. Steam Leaks : Usually indicate a worn or dirty door gasket. Calibration switch to distilled water |
: Regularly calibrate temperature sensors to ensure accuracy and valid sterilization cycles. Important Note on Model Names Be aware that the "MAC 1200" name is also used by GE Marquette

| Symptom | Likely Cause | Manual-recommended action | |---------|--------------|----------------------------| | Does not heat | Low water level | Add distilled water until float switch activates | | Pressure rises slowly | Exhaust valve not fully closed during heating | Close valve completely | | Timer does not start | Temperature below set point (thermostat) | Wait for chamber to reach set temp | | Safety valve releases | Overpressure or regulator failure | Turn off power; check thermostat and valve | | Sterilization fails (biological indicator positive) | Air not fully removed | Extend initial air purge phase | | Water brown/gunky | Tap water used | Descaling required; switch to distilled water |
