a location that can be accessed by third parties may result in unexpected accidents (e.g. the unit may

be used for unintended purposes).

Do not leave the plastic bags used for packing in a place where they can be reached by small

children as this may result in unexpected accidents such as suffocation.

Use the reagent specified by our company for H2O2 decontamination. Using a different H2O2

solution may result in explosion or damage to the incubator.

When performing H2O2 decontamination, securely close the internal and external doors. Failure to

do so may be harmful to health due to leakage of H2O2 gas.

During H2O2 decontamination, plug the access hole with the silicon cap that is provided. Failure to

do so may be harmful to health due to leakage of H2O2 gas.

Always use the removal power supply cord that is provided. Other power supply cord may cause

electric shock or fire.

When using CO2 gas for control, make sure that there is adequate ventilation. Using CO2 gas in a

small room without adequate ventilation may cause gas poisoning or oxygen deprivation. In addition,

when opening the incubator doors, do not directly inhale the air in the chamber.

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 gas leak.

Install the incubator in a location with adequate ventilation. If adequate ventilation cannot be

provided, then install an alarm system using CO2 and O2 densitometers.

Do not look directly at UV light. UV light is harmful to the eyes.

Never start H2O2 decontamination when “Warning: UV Bulb Life” is displayed in the message display

area. The UV resolve is not sufficient.

Tube fitting: female straight, adaptive tube OD6mm, Rc1/8

Conversion bush: bush A M12x1, R1/8

Packing: 6A (ID13mm x OD18mm) or seal tape

Note: If the CO2 gas is supplied to multiple CO2 incubators from a single gas cylinder, a CO2 solid will be

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 CO2 gas on the secondary side to 0.03 MPa(G)–0.1 MPa(G) (0.3 kgf/cm2(G)–1 kgf/cm2(G),

4.4 psi(G)–14.5 psi(G)) for gas injection. Recommended pressure: 0.03 MPa(G) (0.3 kgf/cm2(G), 4.4

psi(G)).

Note: Do not set the pressure on the secondary side too high. As the pressure increases, the CO2 gas

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 CO2 gas left and the CO2 gas empty alarm is activated, replace the empty gas cylinder.

Note: When the optional gas auto-changer MCO-50GC is installed, it automatically switches the empty

CO2 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.

ꞏ Close the valve of the CO2 gas cylinder when the CO2 gas is not in use.
