When a toot prompt sound is heard, the process would be ended automatically. Pull out the drainpipe and the device is ready to work. 2. A Model: Take off the rubber lid covering the water inlet at the top of the device. Use a clean cup to pour the distilled water into the reservoir. When a toot prompt sound is heard, you should stop adding water to avoid overflow. Cautions: Distilled water must be used in order to extend the life span of the sterilizer. 1. Before adding water, the sterilizer must be turned on and the panel indicator light is on the initial state. 2. When the water has been filled to the maximum, a toot prompt sound would be heard, and after which any water adding process is without avail. 3. If the water-adding indicator turns on and gives an alarm, please fill in the tank in time when the work is finished. The water remained in the reservoir could still satisfy the need for one working cycle to ensure the normal and safe working of the sterilizer. 7.2 Sterilization Now the IN and OUT indicators have gone out and the sterilization can start. 7.2 (A)Choose the needed sterilizing process and working temperature. Note: When the sterilizing process has been chosen, generally the sterilizing temperature has been the standard default temperature. It is recommended that the 9
default temperature not be changed unless in special application circumstance. 7.2(B)When the sterilizing process has been chosen, the instruments to be sterilized can be put into the chamber. Note: Instruments should be placed on the instrument tray. There should be spaces between instruments to facilitate the air circulation in the sterilizing chamber. While putting the tray into the chamber, it is recommended that you use the attached hand rack to avoid being scalded. 7.2 (C)When the instruments have been put in place, the door can be closed and the knob should be turned to the end. Note: If, when you are closing the door, the sterilizing chamber is still hot and there is steam, it is normal that you may feel great resistance. You just need to add more strength and turn the knob to the utmost. Of course, you can also open the door and let the steam inside dry up, then you will find it much easier to close the door. Or you can push in a bit while turning the knob. 7.2(D)Now you can push the START/STOP button to begin the work, the condition indicator shows HE and the device begins the automated sterilizing process. You can now fully enjoy the work fun the sterilizer brings to you or do other work. The sterilizer will automatically heat, sterilize and dry the articles for you. The whole working process takes about 20 to 35 minutes. The length of working time depends on the number of articles put into the chamber, the initial temperature of the sterilizer and the sterilizing process you have chosen. Note: If the door is not closed properly, LD will flash in the panel while pressing START & STOP button. Close the door properly, or else the sterilizer will not work. If the door is opened during the working process, E6 will be shown in the condition displayer to give the alarm. In this situation, the power of the sterilizer must be turned off to relieve the alarm before the device can be used again. 10
7.2(E)When the sterilization has finished, the condition displayer shows ED and emits prompt sound, you can open the door and take out the sterile instruments. Note: Please use the attached hand rack to take the instruments out of the chamber to avoid scald. When the door is open, the process would return to LD condition, preserving heat and waiting for the next sterilizing process. Before the new process begins, the sterilizer will remain in the heat preservation condition. 7.2(F)If you no longer use the sterilizer, please turn of the main power. (Power indicator light out) Warning: Do not try to open the door of the sterilizer until the pressure gauge reads 0. Special papers or bags that can indicate the sterilizing effect are recommended to use in every sterilization. They should be put together with the articles to be sterilized into the chamber to ensure the reliability of every sterilizing effect. VIII. Abnormal Conditions If abnormal conditions arise in the working process, the sterilizer will automatically give an alarm, release pressure and stop heating so that operator s safety could be securely ensured. Alarm code would be shown in the panel at the same time (For the connotation of alarm codes, please refer to the following table: Malfunction Codes and Handling Methods) When there is abnormal condition, please check the alarm code table and follow the handling methods. If the malfunction still exits, please contact the local dealer or our after-sales service department in time and explain to the maintenance technician the situation as specific as possible, we will offer you help in the shortest possible time.
