19Connecting CO2 gas cylinderWARNINGWhen connecting a gas cylinder to the incubator, confirm the gas type. Confirm that the connectionsare secure and that no gas will leak. Be sure to use the specified pressure. Using an incorrect gas orpressure 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 2 and O 2 densitometers.1. Get a CO 2 gas cylinder ready and install an optional gas regulator MCO-100L.Note:・Use a liquefied CO2 gas cylinder (at least 99.5 % pure). The siphon (dip tube) type cannot be used.・When MCO-100L is not available, install a gas regulator rated at 25 MPa(G) (250 kgf/cm2(G), 3600psi(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 theconnecting port A for CO 2 gas pipe and the gasregulator of the CO 2 gas cylinder.For details on installing the optional automatic CO2cylinder changeover kit (MCO-21GC), refer to page69～71.Note: If the CO 2 gas is supplied to multiple CO 2 incubators from a single gas cylinder, a CO2 solid will beformed in the gas regulator. The gas regulator safety valve will operate, and there may an explosivesound.3. After connecting the gas tube, make sure that no gas is leaking.4. Set the CO2 gas 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 CO 2 gas density control range will increase. Excessive pressure maycause gas supply lines inside the incubator to come loose, which may result in gas poisoning or oxygendeprivation due to gas leak. If gas lines come loose, the incubator must be repaired.5. When there is no CO 2 gas left and the CO 2 gas empty alarm is activated, replace the empty gas cylinderto a new one.Note: When an optional gas auto changer MCO-21GC is installed, it switches the empty CO 2 gas supplyline 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 abnormalitiesare found during inspection, replace the lines immediately.Connecting port A for CO 2 gas pipeLower right side |
