3 Installation
General conditions
§ Position the device on a plane surface with a minimum capacity of 60 kgs.
§ The sterilizer should be placed on a level worktable.
§ Leave at least 10 cm between the device rear part and the wall. The clearance required to open
the door is 40cm.
§ Position the sterilizer 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 sufficiently 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 or other objects on the sterilizer.
Power supply connection
Check the label on the back panel of sterilizer to verify the voltage rating for the unit. Failure to connect
the sterilizer 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
Connect the power cord to an outlet of the appropriate voltage.
Turn on the main power switch on the right side. Open the door to remove all of the inner contents for
unpacking. After switching on, the machine turns on the LCD and shows the door position, water level,
working program, date, time, etc.
Fill the distilled water tank
Manual water filling
When the level of distilled water reaches a minimum level, the distilled water tank icon will flash and beep
three times.
Press the button on the tank lid and open it to the maximum position.
Fill it carefully with distilled water.
If exceeds the maximum level, an alarm will sound, and the distilled water tank icon will blink.
Drain the used water tank
Attach the drain hose on the drain connector located inside the service
door at the left.
Attention: The capacity of the used water tank is approximately 1.5 liters
Preparation of sterilization materials
For the most effective sterilization and to preserve the sample, please follow below:
§ Clean instruments immediately after used.
§ Treat the instruments by ultrasound cleaner.
§ Residual chemicals left over after cleaning and disinfecting process may damage and corrode
parts of the sterilizer, 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 sterilizer.
§ Don’t overload the trays over the stated limit (see appendix 2).

Clean door seal and mating surfaces with a damp cloth.
Note: Do not use bleaching agents or any abrasive materials or substances in the chamber. Failure to
comply may cause damage to the chamber and/or other components.
Caution: To prevent burns, let the unit cool before cleaning gaskets and touch the surface.
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 adjust it.
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.
Replacement of the door seal ring
Open the chamber door. Remove the door seal ring carefully by hand.
Clean the door seal ring carefully with a smooth cloth with distilled water.
Moisten the new seal with distilled water.
Insert the new seal and tap in sequence as follows:
Press in the top and bottom of
the door seal.
Press in the left and right sides
of the door seal.
Press the remaining sections of
the seal.
Caution: Please ensure the chamber and the door are cold prior to replacing the seal ring.
The drain valves
1. Press the included hose
on to the drain valve firmly.
2. Pull the drain valve
outward to drain the tank.
3. Push the drain valve back
after draining the tank.

8 Transportation and storage
Switch off the sterilizer before transportation or storage.
Pull out the plug. Let the machine cool down.
Drain the distilled water tank and the used water tank.
Conditions for transport and storage
Temperature: -20°C ~ +50°C
Relative humidity: ≤85%
Atmospheric pressure: 50kPa~ 106kPa.
9 Safety devices
1. Main breaker: Protection of the instrument against possible failures of the heating resistor.
Action: Interruption of the electric power supply.
2.Thermal cutouts on the main transformer winding: protection against possible short circuit and main
transformer primary winding overheating
Action: Temporary interruption of winding.
3.Safety valve: Protection against possible sterilization chamber over-pressure.
Action: Release of the steam and restoration of the safety pressure.
4.Safety micro-switch for the door status: Comparison for the correct closing position of the door.
Action: Signal of the wrong position of the door
5.Thermostat on chamber heating resistors: Protection for possible overheating of the chamber heating
resistors.
Action: Interruption of the power supply of the chamber resistors.
6.Thermostat on steam generator heating resistors: Protection for possible overheating of the steam
generator heating resistors.
Action: Interruption of the power supply of the steam generator resistors.
7.Door safety lock: Protection against accidental opening of the door.
Action: Impediment of the accidental opening if the door during the program.
8.Self-leveling hydraulic system: Hydraulic system for the natural pressure leveling in case of manual
cycle interruption, alarm or blackout.
Action: Automatic restoration of the atmospheric pressure inside the chamber.
