-The two front feet of the sterilizer are raised by 2 to 3 cm, resulting in the front end point being higher than the rear end
point.

-Artificially open the door to the steps:

(1)Open the small cover of the sterilizer door.(Fig.3.1-5)
(2)Insert the hexagon spanner into the door shaft and rotated clockwise until the door is fully opened.(Fig.3.1-6)
(3)Remove the operation panel placed in the chamber and connect the operation panel and the control panel.
The connector is tightened.(Fig.3.1-7)
(4)Fixed operation panel.(Fig.3.1-8)

ATTENTION:

When you meet the power supply to stop,you can also follow the above steps to open the door.Remove the
instruments in the chamber before the power is restored.
However, it is important to confirm that the pressure in the before the above operation can be performed,
chamber is reduced to 0.000bar

(1)T0~T1 STAGE:the vacuum pump starts evacuating,the operation display appears 4 minutes countdown(Fig.5.4-4).If the
pressure inside chamber reaches -0.850bar(P1) ahead of time,go to the next step in advance.
(2)T1~T2 STAGE:when the pressure reaches -0.850bar,the vacuum pump stops work.This pressure will maintain for 5 minutes and
then measure P2.(Fig.5.4-5)
(3)T2~T3 STAGE:this pressure maintain for 10 minutes and then measur P3.(Fig.5.4-6)
(4)T3~T4 STAGE:this pressure in chamber will be balance.After 2 minutes,time countdown is over.(Fig.5.4-7)
LCD shows evaluation results“PASS”or “FAILURE”(Fig.5.4-8 or Fig.5.4-9).Press “start lock”button exit to Fig.5.4-3 interface.
If evaluation results is “FAILURE”,please check the leakage of seal and leakage of pipeline.

Fig.5.4 -5 Fig. 5.4-6 F ig.5. 4-7 Fig .5.4-8

Pag e 36 of 58

In compliance with EN 13060:2004,the test requires a tightness test (less
than or equal to 13mbar during the 10 minutes of test).If the leakage is more
than this value,the outcome of the test is failed; the seal of the pneumatic
circuit of the device must be chceked.

-0.85bar

WARNNING:

1、Temperature requirements of vacuum test:
the temperature in chamber must be tested under the normal state.
Otherwise, the result of a vacuum test will be inaccurated.

2、We recommend: if you need to do vacuum test,, it should be subjected to vacuum
testing at once after turn on the power! Because after the power turned on, the
heating coil had begin to warm up slowly, the temperature of chamber will rise gradually .

A correct sterilization depends on the processes described below being carried out correctly; these are allequally important and care must be
performed carefully.

1. Preparing the instrumnets to sterilize; 2. Packing; 3. Loading; 4. Sterilizing;

5.Preserving the sterilized instruments; 6.Routine maintenance of the unit.
All the objects must be decontaminated and careful cleaned and dried before sterilized.In the case of instruments with parts that are joined to
each other,divide the parts or them as wide apart as possible.

NOTE:

1.The sterilizer should be put on level worktable.

2.Be sure to use distilled water in order to prolong the use age of sterilizer.

3.Do not jam or cover the sterilizer radiator.

4.Sterilizer instrument should put in the instrument plate,each instrument should have some
gap in order to make ventilation.

5.Freezing water tank should drain out constantly,usually it should drain out one time once the
water saving tank use up.

6.Push the door to the very end while sterilizing.

7.Be sure not to open the door when the pressure has not fall down to 0.0bar.

8.Do not stand clear the door when the door in order to avoid burning.

9.Be sure to power off when fix or back out the seal ring and be sure to do it after enough freezing.

10.Be sure do not to drag the sterilizer on transport.

11.The electric power must contact the earth.

12.Can not be placed tp some where the power is not easily cut off.
