Lifting the instrument by hand should be prohibited. Please use a lift or a forklift or other
lifting apparatus to raise or move the instrument.
Note
Note
5.1 Tools Requirment
a. 2 adjustable wrenches
b. 2 cross screwdriver
c. 1 spirit level
d. 1 lift or forklift or other lifting apparatus with the minimum
loading to be 250 kg
5.2 Installation
a. Place the instrument on the ground as
instructed in Chapter 3.1;
b. Adjust footings: as shown in the figure,
1 of the 4 footings is adjustable.
c. Repeat step b to stack instruments.
Footing Adjustment Method:
1.After stacking the the instrument, turn the hexagon nut down using the wrench to loosen.
2.Insert the screwdrive into the adjustment hole and turn the footing. After the instrument the
leveled (the 4 footings are at the same level), turn the hexagon nut up to tighten.
Please make sure each instrument is level and not shaking when stacking multiple of them.
It is forbidden to load the instrument more than 15 kg of the maximum load. It is for bidden
to exceed the maximum speed, especially for instruments at the 2nd and 3rd levels.
Connect CO

gas tank
1. Install a regulator with flow control valve onto the gas tank (see optional accessories
2
table). Please choose a regulator with the primary preset pressure to be 25 MPa (
250kg/cm
.

3500l b/in ), and secondary preset pressure to be 0.6 MPa (
2.0kg/cm
，
30psiG
).
2. Using the provided pipe to connect the regulator
with the instrument. The gas inlet port is
positioned at the right side of the instrument
(as shown in figure 1).
3. Adjust the secondary flow control valve to point the pointer to 0.1
– 0.2MPa (as shown in figure 2). It may cause the pipe connect the
incubator and the inlet port to fall off and the leak of the CO
2
gas if the
secondary pressure is too high. High CO
2
concentration will do harm
to your health and may cause suffocating and death. Maintenance is
required if the inner pipe falls off.
4. Check if there is leak at the connections (pipe with regulator, pipe with
inlet port of the instrument, and pipe with filter).

Note:
1. Do not turn the pressure adjustment rod on the regulator when changing the gas tank.
It will change the secondary pressure if the pressure adjustment rod is turned and more
adjustment will be needed. It may cause the pipe connect the incubator and the inlet port
to fall off. Maintenance is required if the inner pipe falls off.
2. Inspect the conncection of the pipe regularly to ensure it is safely connected. If the pipe
is damaged or aged, change pipe.
3. Use the stainless steel hoop to tighten the connection point of the PU pipe and the filter
to prevent the pipe from falling off and leakage of gas.
4. The CO
2
gas purity is more than 99.99%. Low gas purity may cause blocking of the
filter or damage of the electromagnetic valve.
Make sure the gas supply meets the specified requirements. Make sure all the
pipes are properly connected. Make sure the gas pressure settings are correct.
Wrong pipe connection or pressure settings may cause CO
2
leakage. High CO
2
concentration will do harm to your health and may cause suffocation and death.
Alternative methods should be taken if there is no sufficient ventilation in the
room to guarantee safety. These methods include gas monitoring and alarming
system. Maintain correct gas pressure can prevent gas leakage.
