6. 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.
Ɣ 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 CO
2
cylinder B to A as an
example.
1. From the Top Display, press the Left Cursor Key for 3 seconds.
2. The CO
2
gas supply line will be switched from cylinder B to A
(When the line needs to be switched from cylinder A to B, press the Right Cursor Key for 3 seconds.)
