Ⅶ．Application procedure

Please refer to your model of the products and above(4. Classification of the products) to confirm the degree of automation, choose the following different instructions to operate the instrument.

A. self control type(-M)

     1.Make sure the power supply coincide with the source of your instrument and be adequately grounded before you plugged into electricity.

      2.open the lid of the instrument,take out the inner cylinder,then you will see electric heating tube.

      3. Diverter switch to the position of Exhaust steam on the bottom of the left surface (discharge the cold air out of the sterilizer in the process of temperature rise), turn on a switch of the instrument, power indicator and water indicator will be on and you will hear the buzzer warning,it is a signal that remind the operator should add water now because of water shortage.(Notes:it is better add tapwater,not purified water or distilled water.)

       4. Use a plastic tube to connect the water tap to the heating tube(or remove the round covering in the bottom of the inside cylinder and connect the plastic tube), turn on the tap to add the water gradually until the water indicator runout,now the working indicator should be on and the instrument set heating to work.

5.Fit the inner tub to the instrument, put the wrapped goods ready for sterilization in sequence into the inner tub(the suitable volume is 200mm×200mm×100mm),make sure that there is still some space left inside of the tub in order to let the steam penetrate well into the goods and increase the effect of sterilization.also please take care that the security valve, exhaust valve and the steam hole in the pressure control switch not be plugged during the process,at last,fasten the lid.(notes: if the locking way is by securing rod,then please tightened it in diagonal form)

6. when the instrument begin to start, the working indicator should be on. Turn off the Exhaust steam/discharging water knob on the bottom of the left surface as soon as the pressure gage reach about 102℃.(If the customer have the high requirement on the uniform temperature in different parts of the inner cylinder,then you can switch the Exhaust steam/discharging water knob towards the leftside a little bit of time to discharge the small amount of steam continuously to ensure the uniform temperature inside. )When the the pressure gage reaches about 0.142MPa, the pressure control switch will be switched off automatically,and now it is time to start the manual sterilizing timing(when the working pressure inside of the inner cylinder exceed the limits,the security valve will take off to release the pressure automatically ).During the process of manual sterilizing timing,if the working pressure drops within the limits of the pressure control switch,the instrument will continue heating antomatically and keeps such disconnected heating repeatedly until the manual sterilizing timing is up.

7.Please turn off the power as soon as the sterilization finishes, Diverter switch to the position of Exhaust steam on the bottom of the left surface to relief the pressure,it is not allowed to take out the sterilized goods from the instrument until the pressure gage reaches 0.

8. This self-control type have the self - protection device, ,it will switch off the heating power automatically when exceeding the temperature limits,and also the instrument can also switch off the heating power automatically and the user can get a warning light as soon as the water bellows the designed water level.

     1. Make sure the power supply coincide with the source of your instrument and be adequately grounded before you plugged into electricity.

     2.open the lid of the instrument,take out the inner cylinder,then you will see electric heating tube.

     3. Diverter switch to the position of Exhaust steam on the bottom of the left surface (discharge the cold air out of the sterilizer in the process of temperature rise), turn on a switch of the instrument, power indicator will be on and you can set the temperature of displacement,the temperature of sterilization,the time of sterilization,after finish setting these things,please press the run button to start,then you will hear the buzzer warning and see the water indicater on,it is a signal that remind the operator should add water now because of water shortage.(Notes:it is better add tapwater,not purified water or distilled water.)

4. Use a plastic tube to connect the water tap to the heating tube(or remove the round covering in the bottom of the inside cylinder and connect the plastic tube), turn on the tap to add the water gradually until the water indicator is on,and it is in the Temperature - rise period.

5.Fit the inner tub to the instrument, put the wrapped goods ready for sterilization in sequence into the inner tub(the suitable volume is 200mm×200mm×100mm),make sure that there is still some space left inside of the tub in order to let the steam penetrate well into the goods and increase the effect of sterilization.also please take care that the security valve, exhaust valve and the steam hole in the pressure control switch not be plugged during the process,at last,fasten the lid.(notes: if the locking way is by securing rod,then please tightened it in diagonal form)

6. when the instrument is in the period of temperature-rise, temperature-rise indicator will be on,and you can hear the buzzer warning as soon as the temperature reaches the required temperature of displacement, it is a signal that remind the operator should switch off the Exhaust steam/discharging water knob on the bottom of the left surface. (If the customer have the high requirement on the uniform temperature in different parts of the inner cylinder,then you can switch the Exhaust steam/discharging water knob towards the leftside a little bit of time to discharge the small amount of steam continuously to ensure the uniform temperature inside. )when the working temperature reaches the designed temperature,the instrument is in the process of sterilization,then the machine will count down to the end of sterilization.

7.Please turn off the power as soon as the sterilization finishes, Diverter switch to the position of Exhaust steam on the bottom of the left surface to relief the pressure,it is not allowed to take out the sterilized goods from the instrument until the pressure gage reaches 0.

8. This self-control type have the self - protection device, ,it will switch off the heating power automatically when exceeding the temperature limits,and also the instrument can also switch off the heating power automatically and the user can get a warning light as soon as the water bellows the designed water level.

Ⅷ、Points for attention

     1. The shell of the instrument must be adequately grounded and always checked to avoid accidents.

     2. The instrument must be kept in an place which is airy and dry and no inflammables & explosives.

     3.The security valve and the exhaust steam valve should be sent to qualified organization to check regularly to ensure the safety.

4.The volume of the inner cylinder can not be more than 4/5 of the total volume of the instrument.

5. Make sure the sealing ring not contact the oil to avoid steam loss because of the broken adhesive tape.

6. Things which are easy to explode when contacts the steam or boost abruptly during the sterilization are both strictly prohibited.

7.When you want to sterilize the liquid,it is advisable that use a durus Heat resistant glass wares to put the liquid,and the volume of the liquid can not be more than 3/4 of the wares,it is prohibited to use a wrapped rubber or cork at the mouth of the wares,it is advisable to use a cotton plugs.

8.It is prohibited to put sterilized goods(wound-dressing and liquids)with different type and different sterilizing requirement together into one instrument.

9.If the pressure indicator shows not right after long time use,you should have it serviced regularly

10.The security valve should also be examined regularly to ensure the reliability,if the security valve not take off when the working pressure above 0.17MPa,then this security valve should be examined and replaced,it is easy to arise accident because the security valve can not release the pressure well and make the inside of cylinder too much of the pressure.

11.The fuses should also be examined regularly,you should also replace it after long time use,if the instrument doesn’t supply well when you connected to the power,then you should check if the plug and the socket or the fuses is broken or not.
