6. Caution and Maintenance

When stacking sterilized items (with the upper cover completely open), the mesh basket should be placed at the center of the barrel (the mesh baskets should be concentric and stacked up and down). It is strictly prohibited to block the vent holes of the safety valve. Sufficient space must be left to ensure smooth ventilation of the equipment. Otherwise, if the vent holes of the safety valve are blocked, it cannot function, leading to accidents.

1. Before each use, check whether the water level in the sterilization barrel is maintained at the specified level.

2. When the sterilizer is in continuous operation and a new sterilization operation is to be performed, allow a 5-minute interval and open the upper cover to give the equipment time to cool down.

3. When sterilizing liquids (only for program A), the liquid container should be placed in a heat-resistant glass bottle, not exceeding 3/4 of its volume. Use a cotton plug for the bottle mouth, and avoid using rubber or cork plugs without holes.

Special note: Do not release steam immediately after the sterilization of liquids. The residual air can only be discharged after the pressure gauge pointer returns to zero.

4. When sterilizing containers such as beakers, flasks, and test tubes, the opening must face downward or be placed horizontally. Placing the opening upward not only makes it difficult to vent but also hinders steam from penetrating the interior, resulting in poor sterilization effectiveness.

5. For items with different types and sterilization requirements, such as dressings and liquids, do not sterilize them together to avoid damage.

6. Confirm sterilization performance: Sterilization performance varies depending on the type of items, quantity, loading method, and container type. Therefore, use sterilization indicators such as an OK card to confirm. Failure to do so may result in accidents or poor sterilization effectiveness.

7. Do not leave sterilized items in the product: This product does not have a storage function for sterilized items. To prevent recontamination, after sterilizing items such as culture media and instruments, promptly remove them and store them in a dedicated safe box.

8. At the end of sterilization (or in case of malfunctions), the pressure gauge pointer must return to zero. Open the manual vent valve (or place the vent valve lever in the vent position) to allow outside air into the sterilizer. Once the vacuum is eliminated, the container lid can be opened (do not approach the lid with your face). When fully opening the lid and removing the mesh basket, be cautious of burns and pinching fingers. (Be sure to wear protective gloves when removing items. Due to the time required for the liquid temperature to decrease, extra care is needed during removal. Direct contact with hands after the operation may cause burns.)

9. After prolonged use, if the pressure gauge shows inaccuracies or cannot return to zero, it should be promptly inspected. Regular checks are recommended (ideally every 6 months) by comparing it with a standard pressure gauge. If abnormalities are found, a new gauge should be replaced. Every six months, apply an appropriate amount of high-temperature grease to the horizontal beam screw.

10. Keep the equipment clean and dry at all times. The rubber sealing gasket may age over time and should be replaced regularly (recommended every 12 months).

11. During operation, if the pressure gauge indicates over 0.24 MPa and the safety valve does not activate, immediately cut off the power, open the manual vent valve, wait for the pressure gauge to indicate 0 MPa for 1-2 minutes, then open the container lid and promptly replace the safety valve.

12. When troubleshooting requires the replacement of components, it must be done by qualified personnel with professional training or authorized personnel from the manufacturer. Disconnect the power circuit breaker, release the residual air in the container, zero the pressure gauge pointer, and send the safety valve for inspection at least once a year. Lift and lower the handle on the safety valve core several times each week to prevent valve core scaling and air leakage.

13. Do not modify for use: Unauthorized disassembly or repair is strictly prohibited, except for maintenance technicians. Otherwise, injuries may occur due to fire or abnormal operation. If screws or nuts are found to be loose during routine use, tighten them promptly to ensure normal operation.

14. Cleaning (recommended monthly): Empty the water from the container and disconnect the power circuit breaker. After the container has cooled, remove the shelves and mesh basket from the container. Use a brush to remove scale deposits on the inner walls, heating elements, and water level probes. Then, use a towel dipped in alcohol or distilled water to wipe the inner surfaces. After drying, place the shelves and mesh basket back into the container. Store the equipment in a well-ventilated room with non-corrosive gases.

15. The interlock device of the door is composed of a self-locking mechanism and a door control switch. During regular use, ensure the flexible extension and retraction of the self-locking mechanism (recommended quarterly inspection). Do not forcefully open the container lid before the pressure inside the container has been released to zero, as it may damage the self-locking mechanism. The door control switch should maintain flexible contact points. If contact points are stuck or indicator lights are not working properly, prompt maintenance is required.

16. Do not allow children to use or play with the equipment: Otherwise, it may result in burns, electric shock, or injuries.

17. Do not open the drainage valve while the equipment is in operation: When draining the heated water, wait for at least 2 hours after sterilization is complete and ensure that the lid is open before starting the drainage operation. Failure to do so may result in burns or accidents due to the release of high-temperature hot water.

18. Fuse replacement: If the power indicator light does not illuminate after connecting the sterilizer power cord to the power source, disconnect the circuit breaker. Using a Phillips screwdriver, open the back cover of the sterilizer to inspect the fuse (specifications: R015, 10x38, 32A). If the fuse is damaged,replace it immediately.

19. Before moving, transporting, or storing, drain the water from the container, seal the sterilizer lid, disconnect the circuit breaker, and remove the power cord. When moving (release the caster locks first), push the sterilizer on a flat surface. During transportation and storage (secure the sterilizer in the packaging box), prevent loosening and abrasion. Avoid tipping to prevent injuries or accidents.

20. Transportation and storage environmental conditions:

Ambient temperature: -40°C to +55°C
