head, it can block the mouth and nose and cause suffocation.
2. Adjust the leveling feet.
Adjust the leveling feet by turning them
counterclockwise to level the incubator. (See the
illustration on the right.)
Note: Incubating on a leaning tray may have a bad
influence on the cultivation.
3. Ground the incubator.
Ground the incubator during installation to prevent electric shock in case the insulation is not sufficient. If
there is no ground wire at the location, consult with qualified service personnel.
When a ground must be installed
If a grounded 3-pole outlet is not available, then a ground must be installed. Consult with qualified service
personnel.
WARNING
To prevent electric shock, always ground the incubator. If grounding is not possible, then have a ground
installed by qualified personnel. If the incubator is not grounded, it may result in electric shock.
Never connect the ground wire to a gas pipe, water pipe, lightning rod, or telephone ground wire.
Doing so may cause electric shock.
Installing a ground fault circuit breaker
If using the incubator in the location with moisture or humidity cannot be avoided, then it is recommended
that a ground fault circuit breaker be installed in the power supply circuit (i.e., the power supply at the
incubator). Have the circuit breaker installed by qualified service personnel.

Connecting CO2gas cylinder
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 CO2and O2 densitometers.
1. Get a CO2 gas cylinder ready and install an optional gas regulator MCO-100L-PW.
Note:
・Use a liquefied CO2gas cylinder (at least 99.5 % pure). The siphon (dip tube) type cannot be used.
・When MCO-100L-PW is not available, install a gas regulator rated at 25 MPa(G) (250 kgf/cm2(G), 3600
psi(G)) for the primary side, and 0.2 MPa(G) (2 kgf/cm2(G), 30 psi(G)) for the secondary side.
2. Using a gas tube that is provided, connect the
connecting port A for CO2gas pipe and the gas
regulator of the CO2gas cylinder.
For details on installing the optional automatic CO2
cylinder changeover kit (MCO-21GC-PW), refer to
page 69～71.
Note: If the CO2gas is supplied to multiple CO2incubators from a single gas cylinder, a CO2solid will be
formed 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.
4. Set the CO2gas on the secondary side to 0.03 MPa(G) (0.3 kgf/cm2(G), 4.3 psi(G)) for gas injection.
Note: As the pressure increases, the CO2gas density control range will increase. Excessive pressure may
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 CO2 gas left and the CO2 gas empty alarm is activated, replace the empty gas cylinder
to a new one.
Note: When an optional gas auto changer MCO-21GC-PW is installed, it switches the empty CO2 gas
supply line to the other automatically. Refer to page 69～71.
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.
