1, each time before use, should check the main body to have 4 liters of sufficient water, water level over the electric heating tube.
2, in the beginning of heating, should be the bleeder valve plate hand dial to "steam" position. So that the cold air inside the sterilization barrel with the heating to escape. Otherwise, the penetration of steam will be hindered by the air and do not get the expected sterilization effect, the release valve after exhaust, put down the wrench, such as a large number of vapor leakage, just pull the wrench up and down repeatedly a few times.
3, sterilization of liquids, liquids should be filled in a hard heat-resistant glass bottle, the liquid volume should be no more than 3/4 of the glass bottle volume. The mouth of the bottle is stuffed with cotton gauze and wrapped around the neck of the bottle with a sand cord. Do not use unpunched rubber stoppers and corks to prevent the glass bottle from bursting. It is best to place the glass bottle in an enamel or metal tray with a volume slightly larger than it, in case the glass bursts, the liquid will not be lost and damaged to the inner wall of the sterilizer. Special attention should be paid to the end of sterilization, do not immediately release steam. Should be in accordance with the "four, the use of" the seventh step of the operation, to avoid accidents.
4, for different types, different sterilization requirements of the goods, such as dressings and liquids, etc., do not put together sterilization, so as not to lose sight of the other, resulting in losses.
5, the end of sterilization, if the pressure gauge pointer has returned to zero, and can not open the lid. At this time, the bleeder valve wrench should be dialed to the "steam" position. So that the outside air into the sterilization, you can open the lid.
6, the pressure gauge used for a long time, if the pressure gauge pointer can not return to zero, should be timely maintenance. Normally should be regularly calibrated with a standard pressure gauge, if not normal, should be replaced with a new table.
7, the best sterilizer with ionized water or distilled water, so as to reduce the water chemical dissolved in the sterilization heating precipitation, deposition at the bottom of the sterilizer and the surface of the electric heat. Affect the normal work of the electric heaters.
8, rubber sealing ring aging after a long time, should be regularly replaced.
9, the sterilizer is not in use, should keep the sterilizer clean and dry. This will extend the service life.
10, after the end of sterilization, to open the cover, the pressure gauge must be in the zero position, and the venting valve wrench should be dialed to the "steam" position.
