Connecting a CO
2
gas cylinder
1.
Prepare a CO
2
gas cylinder and attach the optional gas regulator MCO-010R.
Notes:
• Use a liquefied-CO
2
gas cylinder (at least 99.5 % pure). The siphon (dip tube) type cannot be used.
• When MCO-010R is not available, attach a gas regulator rated at 25 MPa(G) (250 kgf/cm
2
(G), 3,600
psi(G)) for the primary side, and 0.25 MPa(G) (2.5 kgf/cm
2
(G), 36 psi(G)) for the secondary side.
2.
Connect the connecting port A for the CO
2
gas pipe and the gas regulator for the CO
2
gas cylinder using the
included gas tube
.
When CO
2
gas auto-changer MCO-50GC (optional) is installed, refer to page 75 for the
connection.
Notes:
• This product employs a tube fitting. Refer to the following steps to attach and remove the tube.
(1) Attaching the tube
Insert the tube all the way to the end so that the tube is secured by the inner locking hook and sealed
with elastic sleeve around it.
* In order to make sure that the tube is securely attached, pull the tube after connection. If the tube
comes off, pull the release ring, and then reconnect the tube and check if it does not become detached.
(2) Removing the tube
Disconnect the tube while pressing on the release ring to remove the tube.
• Connecting to the gas regulator (MCO-010R)
<When connecting to the joint for the gas regulator tube>
(1) Attach the conversion joint that came with the incubator unit to the gas tube.
(2) Connect between the joints using the connection tube, and then secure the connection with the
tube bands.
