3. Installation
3.1 General conditions
Position the device on a plane surface with minimum capacity 60 kgs.
The sterilizer should be placed on a level worktable.
Improper water level in the chamber could cause a sterilizer malfunction.
Leave at least 10cm between the device rear part and the wall. The clearance required to open the door is 40cm.
Position the autoclave at such a height as to make it possible for the operator to check the whole sterilization chamber and
carry out the normal cleaning operations.
The room where the device is installed must be enough ventilated.
Do not install the device near washing basins, taps, etc. where it is likely to be splashed.
Do not lean on the door when it is opened.
Do not place trays , papers, fluid containers, etc. on the sterilizer.
3.2 Power supply connection
Check the label on back panel o sterilizer to verify voltage rating for the unit. Failure to connect the autoclave to an
appropriate power supply could result in damage to the unit, and electrical shock to personnel.
Plug power cord into a properly polarized and grounded receptacle rated. A dedicated circuit only used for the sterilizer is
recommended.
Never connect the device pin to reductions of any type.
4 Setup
Open the door and remove all of the inner contents for unpacking.
Connect the power cord to an outlet of the appropriate voltage.
Turn on the main power switch on the right side. After switching on, the machine turns on the LCD and shows the door
position, water level, working program, date, time and etc.
Note: The control panel will be locked for the initial 10 seconds after powering up for system initialization.
Notice: Before using the sterilizer or at any time the low water level icon blinks, fill the distilled water tank with
distilled water.
Instructions Manual

4.1 Fill the distilled water tank
Ensure that the drain valve is closed.
Tap the button and open the water tank cover.
Use only high quality distilled water. (see Appendix 1)
4.2 Preparation of sterilization materials
For the most effective sterilization and to preserve the sample, please follow below:
*Clean instruments immediately after use.
*Treat the instruments by ultrasound cleaner.
*Residual chemicals left over after cleaning and disinfecting process may damage and corrode parts of the autoclave, always
rinse off the instruments using distilled water.
*Follow instrument manufacturer’s guidelines and recommendations for handing and cleaning instruments prior to
sterilization.
*Check the manufacturer’s instructions as to proper procedure for sterilizing of each item.
*Arrange the samples of different materials on different trays or with at least 3cm of space between them.
*Clean and dry instruments thoroughly before placing them into tray.
*Always insert a sterilization paper or cloth between the tray and sample to avoid direct contact.
*Arrange the containers (glasses, cups, test-tubes, etc) on one side or inverted position, avoiding possible water stagnation.
*Don’t stack the trays one above the other or put them in direct contact with the walls of the sterilization chamber.
*Always use the instrument tray handle.
*Wrap the samples one by one or, if more tools have to be set in the same bag, verify that these are made of the same
material.
*Don’t use metallic clips, pins or other, as this jeopardizes the maintenance of the autoclave.
*Don’t overload the trays over the stated limit (see appendix 2).

5.2 Running the sterilization program.
After selecting program, the materials to be sterilized can now be placed on the
tray, placed inside the chamber by the tray handle.
After the instruments are loaded, you may close the door.
The icon will be lightened.
Caution: You must turn the door handle to the max. position,
otherwise the machine will alarm and prevent starting the cycle.
5.3 Start the sterilization program.
After the START button is taped, the stage and the status of the current cycle will appear on the display. The sterilizers will
perform the program automatically. (see appendix 2).
5.4 End of cycle
After cycle is completed, the printer will be activated and print out a report of the cycle (if the optional printer has been
connected) or save the report in the USB drive (optional).
Caution: Always use the tray handle to load or unload the tray into the autoclave.
Failure to do so can result in burning.
5.5 Manual abort of the program
It is possible to interrupt a started cycle prematurely. If you need to interrupt a cycle and remove the items urgently, you may
hold the START button for 3 seconds during the drying time to skip the dry cycle.
If you interrupt a cycle before it reaches the “Drying” step, the items inside the autoclave must be considered not be
sterilized.
If you need to interrupt a cycle after the holding time of the sterilization cycle and during the drying step, the items
inside the autoclave can be considered sterilized.
Caution: Depending on the status of the Cycle, steam can escape from the sterilization chamber when you open the
door.
Note: If the power shut off during the cycle is working, the screen will show a
special picture when power on again.

5.6 Record of the cycle
USB Flash memory (Optional)
A USB drive can be used as a method of storing a report of the cycle. To do so, insert the USB drive into the slot located on
the service door of the sterilizer.
The information will automatically output directly to the USB drive after the cycle has completed. The name of the file is
determined by the serial number of the machine and the cycle number.
For example:
The serial number is E00001. The cycle number is 0012.
The file name in the USB stick is E00001_00012E00.txt.
The first two numbers represent machine number.
The middle four numbers represent cycle number.
The last two numbers represent error code.
E.g. 00:no error;01: error E01
5.7 Printer (Optional)
5.7.1 Connect the printer cable.
5.7.2 Connect the printer power.
The printer (Optional) will print a report of the cycle that just ended. At the end
of each cycle the printer will print out a report of the cycle.
5.8 Report
In this menu you can read the report of the last 20 cycles stored in the internal
memory of the sterilizer.
Tap the button Prog. to the display of report. This will show the cycle No. Tap the

7.1 Clean the distilled water tank
Disconnect the main cable.
Drain the tank completely using the drain tube and leave it connected into the connector in a
open position.
Clean the internal surface with a soft sponge and a small soft brush for the areas that are difficult
to reach using and a mild soap.
Remove the filter and clean it with a small soft brush and mild soap, rinse it with distilled water
and put it back in to the position.
7.2 Clean Chamber, door seal, trays and tray Rack.
Remove the trays and tray rack from the chamber.
Clean trays, rack and inside of chamber with mild soap.
Rinse the trays, rack and inside of chamber with a smooth cloth and distilled water.
Examine door seal for possible damage.
Clean door seal and mating surfaces with a damp cloth.
Note: Do not use bleaching agents or any abrasive materials / substances in
chamber. Failure to comply may result in damage to the chamber and/or other
components.
Caution: To prevent burns, let unit to cool before cleaning gaskets and
touch the surface.
7.3 Door adjustment
Under normal circumstances the chamber door does not require adjustments. However, if the seal
fails (resulting in steam leaking from the front of the chamber), you may use the spanner tool to
tighten the door seal.
Open the door.
Insert the spanner tool in the gap beneath the plastic cover; use the spanner to grip the adjusting
nut. Turn the nut counter clockwise as the figure below. This will tighten the sealing plate.
Turn the nut until the sealing plate is tight. If the door knob is too tight, you may also turn the nut
clockwise to loosen it.
Caution: Never adjust the chamber door while the door is closed.
