1. Brief Introduction
This autoclave is automatic type steam sterilizer, which is very easy to operate. The parameters and conditions of the
program will be displayed automatically on the digital screen during the sterilization. If there’s problem, the autoclave will
alarm automatically. If there’s over-temperature or over-pressure, the autoclave will automatically cut off the power and
ensure the safety of operator. Inside the autoclave, there’s a waste water tank to collect waste water and vapor to ensure
they will not pollute the inner clean pipes.
2. Using Range
This autoclave can be used for medical purposes, e.g. In general medical practices, dentistry, facilities for personal
hygiene and beauty care and also veterinary practices. It is also used for materials and equipment which are likely to
come into contact with blood or body fluids, e.g. Implements used by beauty therapists, tattooists, body piercers and
hairdressers.

5. Installation
The autoclave is packed by a wooden carton. To open the carton, you need a flat screwdriver to open the cover. Then, the
autoclave can be lifted out by 2 persons.
5.1) When installing the autoclave onto the table, please keep the autoclave at least 10 cm away from surroundings. And
keep the rear side of the autoclave at least 20cm away from the surrounding.
It is recommended to install the autoclave in a well-ventilated location. Don’t block the radiator of the sterilizer.
Keep the table stable & horizontal.
5.2) Adjust atmospheric pressure
Because different countries have different atmospheric pressure, the user shall adjust the atmospheric pressure before
first use.
Adjust method:
Cut off power
Open the door of autoclave
Turn on the power, and keep it for 20 seconds. Then cut it off.
Atmospheric pressure for autoclave is successfully adjusted.
5.3) Adjust time and date
Please refer to information stated in 4.3.7.
Please ensure the table for installation is strong enough for an autoclave.
The autoclave might not run if the user does not adjust its atmospheric pressure.

6. Operation
Preparation before using
Before using, please connect power supply, turn on the switch. After that, the LCD screen will be turned on and show the
main menu. At this moment, the autoclave has been ready for use.
Before the first use, the LCD will show “Please fill water”, please fill water from the top of the autoclave. After enough
water has been filled, the alarm will disappear and user can use this autoclave now.
6.1 Fill water
If LCD shows “Please fill water”, that means, the water inside is not enough for run a sterilization cycle and you need to fill
water before starting a new sterilization cycle. (If LCD shows during a sterilization cycle, you need not stop the current
sterilization cycle because the water inside is only enough for the current cycle. But for next cycle, you must fill water
firstly.)
This water can be filled from the top of the autoclave. Please see pic. Above. When you are filling water, you will hear 2
times of beep:
❖First time beep: it means the water inside is enough for a new sterilization cycle. You can stop or continue filling
water.
❖Second time beep: It means, the clean water tank is full. Please stop filling water now.
6.2 If you want to use a flash disk to save the sterilization records, please insert the flash disk into USB port.
6.3 Working
When water tank has enough water and waste water tank is not full, it is ready for working.
6.3.1 Put the loads (instruments etc.) into the chamber
Warning:
➢Ensure the total CBM of the loads is less than 70% of the CBM of the chamber.
➢Keep the loads away from the surface, air outlet of chamber. Keep the loads at least 10mm away from the inner side
of the chamber.
➢If you do B&D test, you need to put the test paper at the center of the sterilization package to ensure the reliable test
Please ensure the autocalve is well grounded.
Only distilled water can be used for the autoclave. Otherwise, there will be problem with the steam
generator and solenoid valves. The user shall be responsible for the problem if he/she uses other
kinds of water.
Before filling water, please turn on the autoclave and ensure the autoclave is horizontal. After filling
water, if possible, please drain the waste water.

result.
➢When putting into and taking out the loads, you shall use the tool attached to prevent your hands from touching the
hot surface.
6.3.3 Set up the parameters
Set the parameters：KEEP TEMP, PRINTER, PREHEAT if in need.
6.3.4 Close the autoclave’s door
If the door is not locked, the LCD will show “Please close the door”.
6.3.5 Choose sterilization program, then start
After the door is closed, choose the relative sterilization program according to the kinds of loads in the chamber.
All the sterilization programs are in “USER” menu. You can press UP or DOWN button to move the cursor to USER menu,
then press OK to enter the menu. Inside the menu, you can press UP or DOWN to choose the sterilization program. After
that, you can press OK. Then, the LCD will show “please push the start key to start” , after seeing that, you can press
“START/STOP” to run the program you selected.
The whole sterilization cycles will be automatically finished. You need not do anything during the programs. The period of
whole cycle is influenced by the initial temperature, the kinds and quantity of the loads.
When the cycle is finished, LCD will show “END”together with 3 beeps. The user can open the door and take out loads
inside now.
6.3.6 After using, you shall turn off the autoclave. If you will not use it for a long time, you shall disconnect the power
supply.
6.3.7 If The LCD shows “PLEASE DRAIN WATER FROM WASTER WATER TANK!”，this mean the waster water tank is
full, you must drain the waste water.
7. Abnormal Situations
The sterilizer will give alarm, release pressure and stop heating automatically if it has any abnormal situations during
If the temperature and pressure inside the chamber are high, the door will be difficult to be closed.
We suggest to close the door quickly, or, you can wait 30 seconds, then close the door.
The user shall fill in water promptly if there is a low-water alert. Otherwise it will show “E08 or E9”
error alarm.
You shall use a tray-holder tool when taking out loads to prevent scald.
Don’t open the door until the pressure is within “-05~05”.
To ensure the effectiveness of sterilization, during daily use, we suggest putting test paper or
pouches with indicators together with the loads into the sterilization chamber.
The waste water might be very hot, please be careful when you are draining them.

16
working. It will absolutely keep the user safe and display the error code( See the below page 14).
If alarm appears, please write down the error code No. and cut off the power. Don’t open the door and then turn on the
power again to wait the pressure turn back to “-0.5~0.5”.
Below is a list of alarms. If the user cannot solve the problem according to below chart, please contact your local
distributor or us, we will help the user solve problems.
