Description
Installation
- Position the device on a plane surface with minimum capacity 60 Kg.
- The sterilizer should be placed on a level worktable.
- Improper water level in the chamber could cause a sterilizer malfunction.
- Leave at least 10 cm 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 have sufficient ventilation.
- Do not install the autoclave near washing basins, taps, etc. where it is likely to be splashed.
- Do not install the sterilizer nearby a heat source.
- Do not lean on the door when it is opened.
- Do not place trays, papers, fluid containers, etc. on the sterilizer.
- Check the label on back panel of 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.
Setup
Open the door and remove all the inner contents for unpacking.
Connect the power cord to an outlet of the appropriate voltage. (See installation).
Connect the draining tube to the vent and the end of the draining tube is fixed into the discharge container (preferably a metal container; if it is a plastic container, make sure that the container is filled with a part of cold water to prevent high temperature deformation).
To power on, press the main switch, the machine turns on the LED.
Note: If the door is open, the display will show "do"; When the door is closed, the display will show "Ld".
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 ultrasonic 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 handling and cleaning instruments prior to sterilization.
- Check the manufacturer' s instructions as to the 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.
Operation
Close the exhaust valve by turning it clockwise to the maximum position.
Fill with the chamber with distilled water (or deionized water).
Select the program temperature.
After selecting program, the materials to be sterilized can now be placed on the tray placed inside the chamber using the tray handle.
After the instruments are loaded, you may close the chamber door. The display will show the current internal temperature.
Caution: You must turn the door handle to the maximum position.
Start the sterilization program.
After the Start button is pressed, the sterilizers will begin the cycle automatically.
Note:
The draining tube must be always connected to the vent and the end of the draining tube must be fixed into the discharge container.
End of cycle
After the sterilization is complete, you will hear a beep and the screen will show "End".
Then you can open the door to remove the sterilized items.
Note:
After the screen shows End, if the gauge is pointer different than 0 bar, do not open the door until it down to zero-scale position.
Note:
After each cycle check the water level of the chamber.

Rinse the trays, rack and inside of chamber with a smooth cloth and distilled water.
Examine gaskets for possible damage.
Clean gasket 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, allow unit to cool before cleaning gaskets and mating surfaces.
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 and Insert the spanner tool in the gap beneath the plastic cover; use the spanner to grip the adjusting nut.
Turn the nut counter clockwise. 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.
