Sixth, attention and maintenance
★ In the use of the equipment, the safety valve should be maintained and inspected. When the equipment is idle for a long time and reused, the small wrench on the safety valve should be pulled to check whether the valve core is flexible to prevent the safety valve from jumping due to the corrosion of the spring.
At the same time when the equipment is working, when the pressure gauge indicates more than 0.25Mpa, the safety valve does not open, you should immediately turn off the power, open the vent valve knob, when the pressure gauge pointer returns to zero, wait for 1-2 minutes, then open the container Replace the safety valve in time.
★ The pressure gauge should be verified within the prescribed time limit to ensure safe use. In daily use, if the pressure gauge indicates unstable or cannot return to zero, it should be repaired or replaced with a new gauge.
★ The rubber sealing ring on the container cover of this equipment will age and deform over time. In addition to proper use in daily use, if the sealing ring is deformed or broken, it should be replaced in time to ensure safe use.
★ If loose screws or nuts are found during daily use of this equipment, it should be fastened in time to ensure normal use.
★ When stacking sterilized items, it is strictly forbidden to block the air outlet of the safety valve (12), and a space must be left to ensure its smooth deflation.
★ Before each use, you must check whether the amount of water in the barrel is kept at the foot of the sterilization barrel.
★ When the sterilizer continues to work, when new sterilization is carried out, it should be left for 5 minutes, and the upper cover is opened to allow the equipment to cool down.
★ When sterilizing the liquid, the liquid canister should be packed in a hard heat-resistant glass bottle, preferably no more than 3/4 volume. The bottle mouth is made of cotton gauze, and do not use unopened rubber or cork. Special attention: the steam is not allowed to be released immediately at the end of the sterilization liquid. The residual steam must be discharged after the pressure gauge pointer returns to zero.
★ For items of different types and different sterilization requirements, such as dressings and liquids, do not put them together for sterilization, so as to avoid loss and loss.
★ Normally keep the equipment clean and dry before extending the service life.
