1. Precaution on Safe Operation

• To ensure the safe and correct use of the instrument, please read this manual carefully before use and operate according to the instructions in the manual. If it is not used according to the method specified by the manufacturer, the protection provided by the instrument may be damaged.
• In addition to sterilization, drying and agar melting, the instrument shall not be used for other purposes; it shall not be used for sterilization of inflammable, explosive, oxide prone or strong acid, alkali, salt water and other substances, or it may cause corrosion of sterilization chamber and pipeline, or even explosion.
• During installation, it is required to connect correctly according to the power requirements on the instrument nameplate; if the voltage fluctuates too much, it is required to use a regulated power supply to ensure the best performance of the instrument; if other types of voltage are used, it is required to use a transformer, otherwise the instrument will be damaged.
• The instrument must be reliably grounded. Do not connect the ground wire of the instrument to the plastic pipe, gas pipe, telephone ground wire, lightning rod, etc.
• Do not let the object block the exhaust port on the safety valve, so as to avoid that the safety valve can not exhaust and relieve the pressure in case of abnormal situation.
• Before opening the chamber cover, make sure that the reading of the pressure gauge is "0 MPa"; when the pressure in the sterilization chamber is higher than "0 MPa", do not open the chamber cover and drain valve, otherwise it will cause high-pressure steam to spray out and hurt people.
• When adding distilled water into the sterilization chamber, do not leak the water into the control circuit, so as to avoid electric shock accident or other faults.
• When using cleaning or other bags, please put the bag in the stainless steel basket first, and then put it into the sterilization chamber, otherwise the accuracy of temperature may be affected.
• Pay attention to observe the temperature in the sterilization chamber. The temperature is high at the end of operation. When opening the cover, pay attention not to put your face and hands close to the sterilization chamber to prevent scalding caused by steam spraying. When taking out the articles from the sterilization chamber, wear heat insulation gloves. Since the liquid needs to be cooled for a certain time, when the sterilized liquid material is taken out from the sterilization chamber, it is necessary to confirm that the temperature has dropped to a sufficiently low level to avoid scalding.
• Distilled water must be used as sterilization water to avoid affecting the service life of sterilizer. When the instrument works continuously, it shall be ensured that there is an interval of more than 15 minutes for the instrument to cool down. Otherwise, the instrument will not be able to produce enough saturated steam.
• In case of any abnormal situation (such as abnormal sound, smell, smoke), turn off the power supply immediately, pay attention to observation, and contact the local dealer or our after-sales service department after the abnormal situation no longer continues.
• It is recommended to place a pressure steam sterilization chemical prompt card (hereinafter referred to as the chemical indicator card) on the sterilized substance for each sterilization. After a sterilization cycle, when the color change of the chemical indicator card coincides with the temperature and temperature duration to be represented, it indicates that the temperature and temperature duration reached have met the requirements of the sterilization Institute If necessary, sterilization can be carried out; otherwise, sterilization requirements are not met.

When open the lid,turn the handle slightly toward the opposite direction that it is wrongly operated, and then turn the handle in counter-clockwise until the cover is released.

○Never press STOP button casually to stop the running program during sterilizing of liquids to avoid the liquid overflowing into the sterilizer chamber and even blocking the valve and pipelines.
○Be careful not get burnt by the hot steam while open the lid

9、Take out the sterilized articles
1）Always wear the heat insulation gloves when taking articles out after sterilization,and wait until the steam disappears before reaching into the sterilizer chamber.
2）When sterilize the liquids,make sure taking articles out with enough low temperature,due to slow cooling sipped of liquid.
3）When installed with load thermometer, be careful it will be stuck while taking baskets out

10、Turn off the power

1）The power switch should be turned off at the end of the day's sterilization work or when it is not in use for a long time.
2）At the end of the day's work, it is recommended to drain out all water in the sterilization chamber.

II.Creating,Modifying,Deleting the Program
1、Creating and modifying the program
Find the required sterilization mode by pressing the "UP" or "DOWN" key, and then press the "SET/ ENT" key to enter the parameter modification interface. If there is a function of setting and enabling password in the background, the administrator password should be input. In the setting process, if you press the "DATA" key, the parameter settings will not be saved and return to the standby state; if you press the "SET/ ENT" key during the setting process, the parameter settings will be saved and a new sterilization mode will be created. Press "START" again to run the program.

Figure 13
2、Deleting Program
●If you need to delete the program, press DELETE PROGRAM
●Default programs can not be deleted.
3、Setting the sterilizing time
●Some items (such as liquid) have high thermal inertia, in order to obtain the ideal sterilization effect, it is recommended to use the load thermometer;if no,set a longer sterilization time.
For example, for 3L water in a flask,when the chamber temperature reaches set temperature after 20 minutes, but the liquid in the bottle hasn’t reach yet, it needs 33 minutes more to reach. So, the sterilization time should set to be 53minute. Actual required sterilizing time(53min)=Normal sterilizing time(20min)+Delay time(33min)
●When installed with load thermometer, the system will begin sterilization process only when the sensor put in the liquids reaches the set temperature.
●When sterilize waste processing bags, 300-500ml water will help to shorten the heating up time.
●A delay time is also needed for plastic products.
