6. Attention And Maintenance

Note :
1.Please ensure the EMC environment before use, so that the equipment works properly.
2.Recommend that users evaluate EMC before the device is used to ensure that the instrument works properly.
3.Prohibit the use of this instrument next to a strong radiation source, otherwise it may interfere with the normal operation of the instrument.
This product will not produce strong electromagnetic wave during operation, but in order to ensure the normal use of other medical devices, try to avoid the use of other highly sensitive instruments and equipment at the same time, so as to avoid the interference of the instrument and equipment by electromagnetic sources.
1. Stacking sterilizing articles (completely opening the upper cover), the basket should be placed in the center of the barrel (the basket and basket should be concentric, stacked up and down). Otherwise, the safety valve can not work because of the hole blockage, resulting in accidents.
2.When the sterilizer continues to work, leave 5 minutes for new sterilization operations and open the upper cover to allow the equipment time to cool.
3.When running the "liquid sterilization" program, the liquid should be canned in a hard heat-resistant glass bottle, not more than 3/4 volume, the bottle mouth cotton yarn plug, do not use unperforated rubber or cork.
Special note: Do not release steam immediately at the end of sterilizing liquid, must wait until the pressure gauge pointer returns to zero before discharging residual gas.
4. Only the beaker, flask, test tube and other containers for sterilization treatment, its opening must be placed face down or horizontally. When the opening part is placed upward, it is not only difficult to deflate, but also not easy to infiltrate steam into its interior, which leads to the appearance of poor sterilization effect.
5. For different types, different sterilization requirements, such as dressings and liquids, do not put together to sterilize, lest cause loss.
6. Confirm the sterilization performance: the sterilization performance is different due to the type, quantity, put-in method, container type, so please use the sterilization indicator of OK card and so on to confirm. Otherwise, it will lead to accidents or poor sterilization effect.
7. Do not leave sterilized articles in this product: This product has no retention function for sterilized items. In order to avoid contamination again, after sterilizing the medium and utensils, please take them out immediately and keep them in a special safe.
8. At the end of sterilization (or in case of failure), the pressure must return to zero or turn off the power . Make the outside air into the sterilizer, after vacuum elimination, the container cover can be opened (Keep your face away from the cover), after the cover is completely opened, take out the basket to pay attention to scalding and clamping. Be sure to wear protective gloves for removal. Due to the drop of liquid temperature will take some time, please be careful when taking out. After running, touching directly with your hand may cause burns. )
9.Apply proper amount of high temperature grease to the beam rod every six months.
10. The equipment should be kept clean and dry at ordinary times. Rubber seal gaskets will age for a long time and should be replaced regularly (recommended 12 months).
11. In use, when the pressure indication exceeds 0.24 MPa, the safety valve does not start, the power supply should be cut off immediately, after 10 minutes, manually open the safety (lift the safety valve cap), until the steam in the sterilizer is completely released before opening the container cover and replacing the safety valve in time.
12.When troubleshooting requires replacement of components, there must be professionally trained qualified personnel or factory personnel. The power circuit breaker is disconnected, the remaining gas in the vessel is exhausted, the pressure gauge pointer can be returned to zero, and the safety valve is submitted for inspection at least once a year.Put up and down the safety valve several times a week to prevent the spool from scaling and leaking.
13.Do not alter use: do not break down or repair without authorization, except for maintenance technicians. Otherwise, it will be injured by fire or abnormal operation.
14. Cleaning (recommended once a month): water should be emptied and power should be cuted off. After the container is cooled, remove the shelf and basket from the container, first use a brush to attach to the inner wall, then dip the towel with alcohol or distilled water, wipe the inner surface, after drying, put the shelf and basket in turn. Store in a non-corrosive gas and well ventilated room.
15.The interlocking device of the door cover consists of a self-locking device and a gating switch. The expansion and flexibility of the locking tongue of the self-locking device should be maintained in daily use (quarterly inspection is recommended). Before the pressure in the vessel is released to zero, the container cover shall not be forcibly opened, otherwise the self-locking device will be damaged. Gated switch should keep the contact up and down flexible, when the contact card rolling and indicator icon abnormal work, should be timely maintenance.
16. Sterilizers shall not be used by non-operators: otherwise they may cause burns, electric shocks or injuries.
17.Do not open the drain valve during the operation of the equipment, wait for more than 2 hours after sterilization and perform the drainage operation only when the lid is opened. Otherwise, it will cause burns or accidents due to the injection of high temperature hot water.
18. Replacement of fuses: when the power cord of the sterilizer is connected to the power supply, when the power indicator lamp is not on, the circuit breaker should be disconnected, the back cover of the sterilizer should be opened with a cross screwdriver, and the fuse (specification type R015,10×38,32 A) should be damaged or replaced immediately if damaged.
19. Before moving or transporting or storing, the water in the container should be emptied, the sterilizer cover sealed, the circuit breaker cut off and the power cord removed. When moving (please remove the locking state of the casters first) push the sterilizer flat; transport, store (fix the sterilizer in the packing box) to prevent loose and scratch during transportation. Avoid overturning, resulting in injury or accident.
20. Environmental conditions for transport and storage:
ambient temperature :-40℃~+55℃ relative humidity range :10%~80% atmospheric pressure range :500 hPa~1060
21. At the end of the product's service life (8 years)(the date of production is shown in the label), the product and accessories shall be voluntarily handed over to the unit or individual with corresponding qualifications for recycling.22. Wiring diagrams:
