6. At constant temperature, open the door and put the culture in.

7. Press "pump1"or "pump2"button to open the pump1 (or2), adjust air flow valve slowly

(counterclockwise), the ratio of CO2 concentration usually 5%, air flow can be adjusted to

760 ml/min.

8. Open the CO2 gas cylinder valves, regulating CO2 PORV, the pressure output is 0.06 Map

(about 0.6 KGF/cm2),open the regulator valve (clockwise) general factory has opened, then

slowly adjust CO2 flow meter to 40 ml/min (counterclockwise). (CO2 concentration ﹦40/

(760 ﹢ 40) ﹦5% V/V).

9. Once that is done, let the temperature stabilize, the device can develop into automatic

control state.

10. If want to see the washing bottles and PH solution, press "light" key to open the lamp.

11. When the incubator stops working, please follow these steps:

1) Turn off the CO2 cylinders and PORV

2) Shut off the pump power to stop working.

3) Open the door and remove humidity. Open the door and let it work a few minutes to

disperse the moisture in the cabinet.

4) Close door and heat ten minutes, turn off power, clean inside.

Ⅷ.Important information.

1. The equipment should be installed in a clean and temperature-stable place.

2. Read the manual carefully and master the correct using methods before turn the power on.

There's fuse in the equipment. If the equipment is not electrified, please check the

fuse. When checking or changing the fuse, please turn off the power supply. Only same style

fuse is allowed.

4.Cannot power-on when there has not water ,to avoid damage internal parts

5. When there are incubation samples inside of the chamber, do not open the UV light,

otherwise the samples are damaged. Please shut off the power when replace tube.

6. Should be send air first, then CO2, before this, should tune the flow meter knob to the

minimum (clockwise), or it will cause the washing-up liquid and PH liquid out due to the

large flow rate, on the other hand, should close CO2 first, then turn off the air

7. Washing liquid and PH liquid in use will be concentrated and pollution, should be open and

exchange, but must pay attention to, add or change should be cut off the air and CO2 gas

source. Shut off the pump and CO2 pressure reducing valve.

8. Should ordinary observation regulating flow meter is accurate or not, in order to ensure the

stability of the CO2 concentration. (Especially ，pressure and flow will influence each other

at the start-up.

9. CO2 gas cylinder pressure is too low for generate flow instability, should transfer or

inflatable before using

10. In order to save electricity and prolong the life of fluorescent lamp, lighting switch can

switch when need

11. The equipment should be well earthed. Check the earth wire carefully before using.

12. This machine is equipped with air pump to maintain flow accurately, should often adjust

the flow meter. Please shut off the power when you change the pump.

13. In order to reduce the closed form difference, influence the uniformity,

so began to heat when closing the door after 10 min( According to actual usage set delay

time).Please do not open the door regular.

14. please let the water in the jacket go if not need for a long time .
