When gas cylinder A is switched to B, remove gas cylinder A and replace it with new one.
Note:
Be careful when handling the empty CO
2
gas cylinder. Some gas may still be left in the cylinder.
Ɣ
When gas cylinder B becomes empty, the line is switched to gas cylinder A again.
The MCO-21GC detects that there is no more CO
2
gas in a cylinder when the CO
2
density in the chamber
does not increase for a while even after opening the CO
2
gas valve in the Incubator. The supply line may
also be switched for other reasons even though there is gas left in the cylinder: blocking or restricting of
gas tube, reduction of CO
2
gas pressure, or improper opening of CO
2
gas cylinder. Always check the gas
quantity in the cylinder before disconnecting it.

Use the following procedure to manual switch the line between CO
2
cylinders A and B (only when
MCO-21GC is installed). This procedure shows switching the line from
㩷
CO
2
cylinder B to A as an
example.
