ZGOOD Sun-II 12L Autoclave Sterilizer User Manual

1. Introduction

This manual provides essential instructions for the safe and effective operation, installation, and maintenance of your ZGOOD Sun-II 12L Autoclave Sterilizer. Please read this manual thoroughly before operating the device and retain it for future reference. This autoclave is designed for steam sterilization of medical and laboratory instruments.

2. Safety Instructions

• Electrical Safety: Ensure the autoclave is connected to a grounded power outlet with the correct voltage (220V 50Hz or 110V 60Hz). Do not operate with damaged power cords.
• Steam Hazard: Hot steam can cause severe burns. Always allow the autoclave to cool and pressure to equalize before opening the door. Use heat-resistant gloves when handling sterilized items.
• Water Quality: Use only distilled water for operation. Tap water can lead to mineral buildup and damage the unit.
• Placement: Place the autoclave on a stable, level surface with adequate ventilation. Do not block ventilation openings.
• Maintenance: Regular cleaning and maintenance are crucial for optimal performance and safety. Refer to the maintenance section.

4. Setup

1. Unpacking: Carefully remove the autoclave from its packaging. Inspect for any shipping damage.
2. Placement: Position the unit on a sturdy, level surface capable of supporting its weight. Ensure adequate clearance (at least 10 cm) around all sides for ventilation.
3. Power Connection: Connect the power cord to a grounded electrical outlet matching the specified voltage (220V 50Hz or 110V 60Hz).
4. Water Filling: Open the water inlet (refer to Figure 3.7) and fill the reservoir with distilled water only until the appropriate level is reached. Do not overfill.
5. Printer Paper Installation: If not already installed, load the thermal paper into the integrated printer as shown in Figure 3.6.

5. Operating Instructions

1. Power On: Flip the main power switch to the 'ON' position. The digital display (Figure 3.4) will illuminate.
2. Load Instruments: Open the chamber door. Place instruments to be sterilized onto the trays (Figure 3.2). Ensure instruments are properly prepared (cleaned, dried, and packaged if necessary). Do not overload the chamber.
3. Close Door: Securely close the chamber door. Ensure it is latched properly to prevent steam leakage.
4. Select Program: Use the control panel buttons (Figure 3.5) to select the appropriate sterilization program (e.g., Unwrapped, Wrapped, Cotton, Plastic) and temperature (121°C or 135°C) based on the items being sterilized.
5. Start Cycle: Press the 'START/STOP' button to begin the sterilization cycle. The display will show the current status, pressure, and temperature.
6. Cycle Completion: Once the cycle is complete, an audible alarm may sound, and the display will indicate completion. The unit will automatically perform vacuum drying.
7. Unload Instruments: Allow the autoclave to cool down and pressure to fully equalize before carefully opening the door. Use heat-resistant gloves to remove sterilized items.
8. Power Off: After use, turn off the main power switch.

6. Maintenance

• Daily Cleaning: Wipe the exterior of the unit with a damp cloth. Clean the chamber interior and trays regularly to prevent residue buildup.
• Water Drainage: Regularly drain the waste water tank using the used water outlet (Figure 3.8). The full water alarm system will alert you when drainage is required.
• Distilled Water Only: Always replenish the water reservoir with distilled water. Never use tap water or deionized water, as this can cause scaling and damage.
• Door Seal Inspection: Periodically inspect the door seal for any signs of wear or damage. A damaged seal can lead to steam leaks and inefficient sterilization.
• Printer Maintenance: Ensure the printer paper is replaced when low (Figure 3.6). Keep the printer mechanism clean.

7. Troubleshooting

The ZGOOD Sun-II Autoclave is equipped with an automatic alarm system for breakdowns. Refer to the display for specific error codes or messages.
