INSTALLATION
Connecting CO
WARNING
When connecting a gas cylinder to the incubator, confirm the gas type. Confirm that the connections
are secure and that no gas will leak. Be sure to use the specified pressure. Using an incorrect gas or
pressure may result in explosion or fire, or in gas poisoning or oxygen deprivation due to qas leak.
Install the incubator in a location with adequate ventilation. If adequate ventilation cannot be provided,
then install an alarm system using CO
1. Get a CO
gas cylinder ready and install an optional gas regulator MCO-100L.
2
Note:
・Use a liquefied CO
・When MCO-100L is not available, install a gas regulator rated at 25 MPa(G) (250 kgf/cm
psi(G)) for the primary side, and 0.2 MPa(G) (2 kgf/cm
2. Using a gas tube that is provided, connect the
connecting port A for CO
regulator of the CO
For details on installing the optional automatic CO
cylinder changeover kit (MCO-21GC), refer to page
75～77.
Note:
・By using 2 tube bands that is 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 an explosive sound.
3. After connecting the gas tube, make sure that no gas is leaking (ex. by using a gas leak detection
spray).
4. Set the CO
gas on the secondary side to 0.03 MPa(G) (0.3 kgf/cm
2
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 gas leak. If gas lines come loose, the incubator must be repaired.
5. When there is no CO
to a new one.
Note: When an optional gas auto changer MCO-21GC is installed, it switches the empty CO
line to the other automatically. Refer to page 75～77.
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.
