1. Product Overview
The ZGOOD 18L Tabletop Class N High Pressure Steam Sterilizer is an automatic sterilizer designed for efficient and reliable sterilization of instruments and materials. It features a drying function and real-time monitoring of pressure and temperature, offering two preset programs and adjustable duration for specific sterilization requirements.
Key Features:
- Efficient Automatic Sterilization: Operates at 1700W with easy operation, real-time pressure and temperature monitoring, and adjustable sterilization duration beyond preset programs (121°C/50 min, 134°C/40 min).
- Clear LED Display: Three LED displays for pressure, temperature, and dry status, providing clear process and time information.
- Automatic Pressure Release & Drying Function: Automatically releases internal pressure and discharges water/steam after completion. The drying function reduces the drying cycle and improves drying effectiveness for internal components and chambers.
- Durable Stainless Steel Chamber: Constructed from stainless steel with a double-layer stainless steel frame and an aluminum instrument tray for maximum capacity.
- Multiple Security Protections: Includes temperature and pressure overload protection, pressure safety lock (prevents door opening until pressure is zero), and safety door locks (ensures operation only when door is correctly locked).
2. Safety Instructions
Read all instructions carefully before operating the sterilizer. Failure to follow safety guidelines may result in injury or damage to the equipment.
- Electrical Safety: Ensure the electrical supply matches the unit's requirements (110 ~ 230 VAC). Do not operate with damaged cords or plugs.
- High Pressure and Temperature: The sterilizer operates under high pressure and temperature. Never attempt to open the door during operation or when the pressure gauge indicates internal pressure. The pressure safety lock prevents opening until pressure is zero.
- Burn Hazard: Surfaces and internal components will be extremely hot after a cycle. Use appropriate protective gear (e.g., heat-resistant gloves) when handling sterilized items or performing maintenance.
- Water Quality: Use only distilled water for operation to prevent mineral buildup and damage to the unit.
- Loading: Do not overload the chamber. Ensure items are arranged to allow proper steam circulation. Disinfection equipment should not be excessive and should not be stacked.
- Ventilation: Ensure adequate ventilation around the unit during operation.
- Emergency Shutdown: In case of malfunction or emergency, immediately switch off the main power.

6. Operating Instructions
- Load Instruments: Place instruments and materials to be sterilized onto the instrument racks. Ensure items are not excessively stacked to allow proper steam penetration. Wrapped items can be placed in sterilized cloth.
- Close and Secure Door: Close the sterilizer door and rotate the door handle clockwise to securely tighten it. Ensure the door is fully sealed.
- Power On: Flip the main switch to the "ON" position. The LED display will illuminate.
- Select Sterilization Program: Use the control buttons on the LED display to select the desired temperature (121°C or 134°C) and sterilization time. The unit has preset programs (121°C/50 min; 134°C/40 min) but allows for adjustment.
- Start Sterilization: Press the "Start" button to begin the sterilization cycle. The display will show the current temperature and pressure.
- Monitor Progress: The unit will automatically monitor temperature and pressure. The display will show "End" when the cycle is complete.
- Drying Function: After sterilization, the unit will automatically release pressure and initiate the drying function to ensure items are dry.
- Open Door: Once the display shows "End" and the pressure gauge indicates zero pressure, carefully rotate the door handle counter-clockwise and open the door. Use the tray removal tool to prevent burns when retrieving hot items.

7. Maintenance
Regular maintenance ensures optimal performance and longevity of your sterilizer.
- Daily Cleaning: After each use, wipe the interior of the chamber and the door gasket with a soft, damp cloth. Ensure no residue remains.
- Water Drainage: Regularly drain any remaining water from the reservoir. Refer to the specific drainage port location in the product diagram.
- Gasket Inspection: Periodically inspect the door gasket for any signs of wear, cracks, or damage. A damaged gasket can lead to steam leaks and improper sterilization. Replace if necessary.
- Exterior Cleaning: Keep the exterior of the unit clean and free of dust. Use a mild detergent if needed, but avoid abrasive cleaners.
- Storage: If storing the unit for an extended period, ensure it is clean, dry, and stored in a cool, dry place.
