1. Description & Usage
Design and mark pressurizd steam autoclaves especially to meet the needs for sterilization of
instruments and devices in clinics,departments in a hospital and laboratories.
Operators include doctors or his/her assistance under doctors supervisions.The autoclave is
computerized, user friendly and easy to operate. Its real time display show all data during the
sterilization cycle. The software program provides auto diagnose, protection against over
heating or over pressurizing,and thus ensure reliability of the sterilization results. Build- in
condenser water collecting system prevents discharge of waste steam and keeps the machine
clean and safe.
12L Three times pre-vacuum pressurized steam Autoclave
12L uses the advanced technology of 3 times fractionated -vacuum and Vacuum drying.
It enables the hot steam to penetrate in thin tube and porous Material and laboratories to
sterilize dental and surgical instruments, dressing and other 135 autoclavable stuffs.

Tips Standard atmospheric pressure: It the atmospheric pressure at sea level. It
refersto 1 Standard atmospheric pressure. The value is 0.1Mpa=1000Hpa=1.0 Bar.
Atmospheric pressure decreases by higher altitude, for instance; at 3000 meter or
lower incremental 1000 meter higher the altitude, the atmospheric pressure decreases
by about 0.1bar.

3.Installation
The Autoclave should be installed in a drafty place allowing minimum 10 cm space at
all sides and 20 cm at the top. The radiation openings at the side of the machine should
not be blocked. The Autoclave should be placed on a leveled counter top.(Fig 3-1)

Fig 3-3
Before using the device, you should make electrical
connections by using the power cord that comes with
the unit. Insert the hollowed end of the power cord in
to inlet of the machine and plug the other end on a
power outlet. Caution: The power supply can afford
1800VA load. Ok, you can turn on the autocalve now.
Fig 3-4
Caution: The power supply must afford at least 1800VA load.
Tips: Before using the Autoclave, please check on the local atmospheric
pressure. If the pressure is lower than 0.095 Mpa or the Altitude is higher
than 500 meters, you will need to contact your distributor who should
reconfigure the controller in the device.

Troubleshooting
1.During venting or drying, the thump sounds. It means that the condensed water collector is
full. You must drain the water from The collector.
2.Hissing from the chamber door. (Solving this problem according to item 6 Door Adjustment)
3.During a cycle, a banging sounds and large steam leaks from the chamber door and displays
E6 code. Please verify whether the door knob is properly turned and locked. If the steam
leaks at the beginning of a cycle, you need to change the seal according to instructions at page 17.
4.When a cycle completes, there are water drops on the instruments.
You may correct the problem by:
1). Please check the drain filter.
2). Reduce the load of the instrument in the chamber, especially the porous and dressing and
other water absorbent materials.
3). You may also wait for a while at the end of a cycle Ed for better drying result. The
autoclave will continue heating the chamber until you open the door.

refilling the water reservoir.(Draining of the collector can be followed as per item 9.2)
7.Chamber door knob must be turned to its locking position.
8.Never try to open the chamber door before pressure displays
0.0
.
9.To avoid burning injuries, power off the machine and let it cool down before replacing the seal.
