INSTALLATION
Connecting a CO
Before connecting a CO
1. Get a CO
gas cylinder ready and install an optional gas regulator MCO-010R.
2
Notes:
• Use a liquefied-CO
• When MCO-010R is not available, install a gas regulator rated at 25 MPa(G) (250 kgf/cm
3600 psi(G)) for the primary side, and 0.25 MPa(G) (2.5 kgf/cm
2. Using the gas tube provided, connect the
connecting port A for the CO
regulator of the CO
Notes:
• By using two tube bands provided, connect the gas tube tightly to prevent it from coming off.
• Make sure that the gas tube is not folded.
• If the CO
gas is supplied to multiple CO
2
in the gas regulator. The gas regulator safety valve will operate, and there may be an explosive sound.
3. After connecting the gas tube, make sure that no gas is leaking (ex. by using a gas leak detector spray).
4. Set the CO
gas on the secondary side to 0.03 MPa(G)–0.1 MPa(G) (0.3 kgf/cm
2
4.4 psi(G)–14.5 psi(G)) for gas injection. Recommended pressure: 0.03 MPa(G) (0.3 kgf/cm
psi(G)).
Note: As the pressure increases, the CO
cause gas supply lines inside the incubator to come loose, which may result in gas poisoning or oxygen
deprivation due to leaking gas. If gas lines come loose, the incubator must be repaired.
5. When there is no CO
Note: When the optional gas auto-changer MCO-21GC is installed, it switches the empty CO
line to the other automatically. Refer to pages 59–60.
Note: The gas lines connected to the incubator will degrade over time. If any deterioration or abnormalities
are found during inspection, replace the lines immediately.
