INSTALLATION
<When using the tube fitting>
(1) Remove the hose joint from the gas regulator.
(2) Attach the conversion bush using the packing or seal tape and then, attach the tube fitting.
(3) Connect the gas regulator and the incubator using the gas tube that came with the incubator unit.
Note: Wind the seal tape around the thread part only. Make sure that the seal tape does not stick out
of the thread.

Note: If the CO gas is supplied to multiple CO
2
formed in the gas regulator. Then, the gas regulator safety valve will actuate, 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: Do not set the pressure on the secondary side too high. As the pressure increases, the CO
density will vary widely. Excessive pressure may 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-50GC is installed, it automatically switches the empty
CO gas supply line to the other. Refer to pages 67–68.

Notes:
ꞏ The gas lines connected to the incubator will degrade over time. If any deterioration or abnormalities are
found during inspection, replace the lines immediately.
