Operation

Before operation, please connect well to the power socket. Push down the main power green switch at the right bottom corner of the front side, when the indicator light is on, it means that the autoclave get through with the electric power, and the process then is in initialization status with “LD” being shown on the screen. The autoclave is not heating while under such initialization status. Press the “Start/Stop” button to start sterilizing work.

7.1 Water filling
After turning on the power to the autoclave, if the “Green” blob light is flashing, please fill more distilled water until the light is off and with a “du” sound. Fill about 1000-1500ml distilled water(3 cups) each time.
During working time, if the “Green” blob indicator is on, the user shall filling water after the autoclave finished working in time, and same time drain out of the used water in time. Or it would have the abnormal voice to effect the working.
Clean the copper filter inside the chamber by brush or ultrasonic cleaner in time, or it would effect the pressure releasing, please clean it one time once 3 days.

Note: Be sure to fill the distilled water

1. The autoclave must connecting the power socket well, and turn on the switch before filling the distilled water.
2. Do not fill the distilled water too much, when there is a “DU” sound, please stop to filling more water.
3. If there is a mark on the lack of source distilled water, please fill distilled water only after the autoclave finished working!

7.2 Working
Start the sterilizing work when the two blob indicators ofwater tank are both off.
7.2 (A) Select the program and temperature for coming sterilizing.
7.2 (B) Put the cleaned instrument onto the mesh trays inside the chamber.

Note: the object apparatus to be sterilized shall be placed on the device trays with enough clearance retained in favor of the air circulation inside the sterilizing room. Please put the device trays into the autoclave by the attached hand-support holder.

7.2(C) Close the door after putting in the apparatus to be sterilized, and revolve the handle to the right MAX position.

Note: Due to the heat air and steam inside the autoclave room, it’s reasonable if there is resistance force from the door when you close it. Please heavily close the door and revolve the handle to and push the door a little bit while close the door.
7.2(D) Press the START/STOP button to start work.When display “HE”, it means the autoclave start its automatic sterilizing process. During the process, you can enjoy the leisure by its automatic function, or you can pay your attention to other work because autoclave runs automatically during the process of heating, sterilizing and drying, and display “ED” means finished sterilizing.

The working time of the whole process is determined by the total quantity of apparatus inside the sterilizing room, the initial temperature of autoclave and the sterilizing process the user chooses.

Note: If the door is not completely closed, a “LD” is showing when press down “START/STOP” button. Please close the door again, otherwise the autoclave can not start work. If the door is releasing during working, the status display will show “E6”as error and the autoclave will stop working, you need to turn off the autoclave firstly, then restart the machine.

7.2(E) When “ED” displaying after sterilizing process, you can open the door and take the sterilized apparatus out.

Note: Take out the sterilized apparatus together with the device trays by the attached hand-support plate in case of scald.
After opening the door of autoclave, the process is reset at “LD” state, which means the autoclave is under heat preservation status and waiting for another sterilizing procedure. Before starting the new sterilizing procedure, the autoclave will always keep in the status of heat preservation.

7.2(F) Please turn off the autoclave by the switch when the autoclave is not working.

Warning: Please don’t open the door when the pressure not reaches “0”.
During each time’s sterilizing process, we recommend you put the special testing paper or bags into the room together with the object apparatus to ensure the liability of the sterilizing.

Emergency Condition

During the running time, the autoclave will automatically raise the alarm, release pressure, stop heating and display the warning code(The definition of the warning code is as the below table: malfunction code and resolving method )for ensuring the safety of the operator if the emergencies occur.
Any emergencies happen, please check the warning code table for resolving the according malfunctions. If not possible to resolve, please contact the dealers. We will try our best to provide help to you in short time.

(4) Check the correctness of the parameter of the new fuse replaced.
9.4 Clean the sealing ring periodically
The user shall clean the sealing ring periodically for avoiding the influence to the seal caused by the dust/dirt left due to the long period use. Use the smooth cloth with distilled water to wipe the surface of the sealing ring or sealing cap gently.
The user shall discharge the sealing ring for further cleaning or replacement if the air-leaking problem can not be resolved after the above process (The user shall discharge the sealing ring periodically for cleaning and inspection as recommendation by the supplier).

9.5 The replacement work for sealing ring
Tool: One flat screwdriver (No sharp edge at the head)
A. One hand catches the lip of the sealing ring, the other hand insert the screwdriver into the clearance between the sealing ring and the door for raise up the sealing ring.
B. After raising up part of the ring, you can use hand to draw the whole ring out.
Wash its groove after drawing out the ring and pay attention to see whether it’s spoiled or not in consideration of the necessity of replacement.
C. Put back the ring to the original door groove after cleaning. Most Important: the inset work must be done equably to the groove During the installation, the laid four equal points of the ring must be inserted to the groove firstly, later for the same work for the remaining segments of the ring. After finishing, press the sealing ring equally by the force of hand.
D. Note: The inner circle of the ring may be raised up when insert the ring into the groove. Please press it to the groove by using the screwdriver carefully.
Shut off the power and cooling the autoclave sufficiently before inserting the ring for avoiding scald.

9.6 Shut off the power before service or components’ replacement, and the service or replacement work shall be done by the supplier or his designated technician.
