Laboratory Vertical Autoclave BAVT-403-A

1. Precaution on Safe Operation

• To ensure the safe and correct use of the instrument, please read this manual carefully before use and operate according to the instructions in the manual. If it is not used according to the method specified by the manufacturer, the protection provided by the instrument may be damaged.

• In addition to sterilization, drying and agar melting, the instrument shall not be used for other purposes; it shall not be used for sterilization of inflammable, explosive, oxide prone or strong acid, alkali, salt water and other substances, or it may cause corrosion of sterilization chamber and pipeline, or even explosion.

• During installation, it is required to connect correctly according to the power requirements on the instrument nameplate; if the voltage fluctuates too much, it is required to use a regulated power supply to ensure the best performance of the instrument; if other types of voltage are used, it is required to use a transformer, otherwise the instrument will be damaged.

• The instrument must be reliably grounded. Do not connect the ground wire of the instrument to the plastic pipe, gas pipe, telephone ground wire, lightning rod, etc.

• Do not let the object block the exhaust port on the safety valve, so as to avoid that the safety valve can not exhaust and relieve the pressure in case of abnormal situation.

• Before opening the chamber cover, make sure that the reading of the pressure gauge is "0 MPa"; when the pressure in the sterilization chamber is higher than "0 MPa", do not open the chamber cover and drain valve, otherwise it will cause high-pressure steam to spray out and hurt people.

• When adding distilled water into the sterilization chamber, do not leak the water into the control circuit, so as to avoid electric shock accident or other faults.

• When using cleaning or other bags, please put the bag in the stainless steel basket first, and then put it into the sterilization chamber, otherwise the accuracy of temperature may be affected.

• Pay attention to observe the temperature in the sterilization chamber. The temperature is high at the end of operation. When opening the cover, pay attention not to put your face and hands close to the sterilization chamber to prevent scalding caused by steam spraying. When taking out the articles from the sterilization chamber, wear heat insulation gloves. Since the liquid needs to be cooled for a certain time, when the sterilized liquid material is taken out from the sterilization chamber, it is necessary to confirm that the temperature has dropped to a sufficiently low level to avoid scalding.

• Distilled water must be used as sterilization water to avoid affecting the service life of sterilizer. When the instrument works continuously, it shall be ensured that there is an interval of more than 15 minutes for the instrument to cool down. Otherwise, the instrument will note able to produce enough saturated steam.

• In case of any abnormal situation (such as abnormal sound, smell, smoke), turn off the power supply immediately, pay attention to observation, and contact the local dealer or our after-sales service department after the abnormal situation no longer continues.

• It is recommended to place a pressure steam sterilization chemical prompt card (hereinafter referred to as the chemical indicator card) on the sterilized substance for each sterilization. After a sterilization cycle, when the color change of the chemical indicator card coincides with the temperature and temperature duration to be represented, it indicates that the temperature and temperature duration reached have met the requirements of the sterilization Institute If necessary, sterilization can be carried out; otherwise, sterilization requirements are not met.

Note:

1) Do not open the chamber cover rudely to prevent seal ring from

damage.During the LOCK lever operation, it is necessary to make sure the instrument has been powered on and power switch is also on.

2) After sterilization, the sample should be taken away in time. If the sample is not taken for a long time, it may cause negative pressure, resulting in the lid can not be opened.

(3) Check whether the sealing rings are sticky: If so, separate them so as not to affect the sealing.

Figure 8

3. Add water into chamber

(1) Add water manually( For BAVT-403-A )

•Front water tank: Drain the front water tank. If the condensate water is not promptly drained, it may overflow from the water filling funnel onto the floor.

Figure 9

• Manual water adding: Open the lid, add water to the sterilization chamber from the top and ensure the water level is not higher than the surface of the water plate.

Maintain the water level sensor regularly, and replace the water in the sterilization chamber and water inlet tank frequently to prevent dirt from adhering to the water level sensor and affecting its normal operation.

Note: Do not open the sterilization chamber drain valve or water tank drain valve during sterilization, otherwise it may cause high temperature steam to spray out and hurt the operator.

○ Always check the water level at the bottom of the chamber before each sterilization cycle since frequent water shortages can cause the electric heating tube to boil dry constantly, thereby accelerating its rust and aging, and reducing its service life.

○ Always use purified or demineralized water (conductivity: 10~15us/cm) in the sterilization chamber, and do not use well water, saline water, or hard water, otherwise it may lead to corrosion and scaling of the sterilization chamber and shorten the service life of the heating element.

(2) Add water automatically (For BAVT-403-A )

For BAVT-403-A ,drain the front water tank

For BAVT-403-A , drain the 10L external water tank, if you want to do drying process later, connect the water tank on the right front side of the instrument to the exhaust pipe to collect water discharged after sterilization and before drying.

Figure 10

•If the condensate water in the above water tank is not promptly drained, it may overflow to the floor.

Bring over a full pail(over 30L) of sterilizing water, put the silicon automatic water adding pipe into this pail, and follow the below screen instruction, water will be added into the back storage water tank(28L) and flow into the chamber automatic when you start the work.

Figure 11

Figure 12

•If there is no water in the water tank, when you turn on the machine, screen will show N08, press the ADD WATER button, the water will be pumped into the inner water tank from the 30L outer water tank you just put in front of the machine. And at the same time, the screen B will show ADD2. If you press STOP button shortly, the water pumping will suspend, press the STOP again to continue. If you press STOP button for 3 seconds, the water pumping will be stopped.

•When you press START, if the screen B shows ADD1, it means the water is pumped into the chamber from the inner water tank.

•The water level sensor should be regularly maintained,and it is recommended to frequently replace the water in sterilization chamber and water tank to prevent scale in water attaching to water level sensor and therefore affecting normal work of water level sensor.

Note:○Do not open the drainage valve of chamber or darainage valve of inside steam collecting tank to avoid injury from the high temperature steam.

○The water level inside the chamber may decrease after each cycle, please add new water on time.Lack of water for a long time may cause damage to the heater.

○It is recommended to use distilled water with a electricity conductivity between 10~15us/cm,do not use well water, salt water or hard water,so as to prevent the chamber from corrosion,fouling and shortening the life of heater.

4. Load articles to be sterilized

•Take the baskets out, and put the articles to be sterilized into the baskets

•Put the water plate first, then put the baskets on the waterplate, do not put the basket directly on the heater.

Notes:

VERY IMPORTANT

Clean the articles to be put in thoroughly by cleaning agent and water

While putting the articles into the baskets,make sure the articles is placed well (overlap may cause inadequate sterilization).Put carbon steel devices and stainless steel device in different baskets and put several layer of Kapok paper under the carbon steel devices so as to protect the stainless baskets.

Sterile equipment should be packed with breathable packaging materials such as sterilization bags, sterile paper, gauze bags, etc.

1. When the sterilizer is loaded with plastic bags, the sterilization bags should be placed in the basket first and then in the sterilization chamber, otherwise the temperature control will be affected.

2. When the sterilizer is loaded with a cleaning bag, the opening of the cleaning bag shall be opened, and it shall be confirmed that the bag does not contact the inner wall of the sterilization chamber. During sterilization, if the bag mouth is sealed, the sterilization will be insufficient. If the bag is jammed into the sterilization chamber and the steam cannot fill every corner, the sterilization will be incomplete.

3. When sterilizing glassware such as beakers, conical bottles and test tubes, the glassware shall be placed upside down or horizontally. If the vessel can only be placed directly, a small amount of distilled water or purified water can be put into the sterilized vessel.

4. When sterilizing the liquid, such as chemical reagent or solvent, pay attention to the rationality of the liquid in the container (the volume of the flask shall not exceed 3 / 4, and the volume of the test tube shall not exceed 1 / 2), so as to avoid the liquid overflowing from the container during the process of heating or cooling. Before sterilizing, the cover of the container shall be loosened so as to ventilate, otherwise the container will be broken.

5. When agar is dissolved, the volume of the container should be less than 2 L, otherwise the dissolution will be insufficient. (Note: the Durham test tube with a diameter of more than 6mm shall be used as the sample tube. When the diameter of the sample tube is less than 6 mm, bubbles will remain in the tube, which will affect the sterilization effect).

6. If equipped with load thermometer, please put is in a place not easy to get damaged.

5.Close the sterilizer chamber cover

•Press the middle part of the front end of the chamber cover gently, push the cover opening / closing handle to the left to the locked position, the system will give a sound, and the indicator light "locked" on the display panel will be on.

Note:

○Before closing the cover, check if there are objects in or on the sealing ring, clean it to avoid damaging the sealing ring that may cause the steam leakage.

○Only when the lid close icon on the screen changes to white and not blinking, the machine will start to work.

6. Select or set the program

•For BAVT-403-A there are ten basic modes. For BAVT-403-A ,there are eleven basic working modes available.And these working modes have been saved as nine basic programs (U01, U02, U03, U04, U05, U06, U07, U08, U09), one self-defined program (U10), and one drying program(U11)before delivery.U11 is only for BAVT-403-A.

In the setting process, if you press the "data" key, the parameter settings will not be saved and return to the standby state; if you press the "set / ENT" key during the setting process, the parameter settings will be saved and a new sterilization mode will be generated. Press "start" again to start the running program.

Example: modify u01 program

1) When the "set / ENT" key is pressed, the sterilization temperature, the "ster." character and the sterilization status light on the digital display screen a flash, indicating that the sterilization temperature can be modified. Press the "up" or "down" key to modify the parameters. Then press the "next" key, the sterilization time, "ster." character and sterilization status light on the digital display screen B will flash, indicating that the sterilization time can be modified. Press the "up" or "down" key to modify the parameters.

2) Then press the next key, the exhaust level parameter displayed on the digital display screen a flash, indicating that it can be modified.

3) Then press the next key, the digital display screen B shows "open", and the digital display screen a shows that the opening temperature parameter flashes, indicating that it can be modified.

4) Then press the next key to modify the sterilization temperature.

At this time, to save the parameters, press the "set / ENT" key to exit and generate a new program u09;

At this time, if you do not want to save the parameters, press the "data" key to directly exit and return to the program u01.

Note: the program parameters can only be modified in standby mode. If the parameters cannot be set during the sterilization process of the instrument, you can only press the "data" key to view the sterilization parameters.

2. Deleting Program

•If you need to delete the program, press FUNC+STOP to delete.

•Default U01-U05 programs can not be deleted

3. Setting the sterilizing time

•Some items (such as liquid) have high thermal inertia, in order to obtain the ideal sterilization effect, it is recommended to use the load thermometer;ifno,set a longer sterilization time.

For example, for 3L water in a flask,when the chamber temperature reaches set temperature after 20 minutes, but the liquid in the bottle hasn't reach yet, it needs 33 minutes more to reach. So, the sterilization time should set to be 53minute. Actul required sterilizing time(53min)=Normal sterilizing time(20min)+Delay time(33min)

•When installed with load thermometer, the system will begin sterilization process only when the liquids reaches the set temperature.

•When sterilize waste processing bags, 300-500ml water will help to shorten the delay time while heating up.

•A delay time is also needed for plastic products.
