Items to check and countermeasures
Is the ambient air environment around the Incubator normal? Is
there a source of polluted gas in the vicinity?
A HEPA filter is used for the Incubator CO
concentration is slow to recover when the CO
normal, it is possible that the HEPA filter may be clogged. Consult a
Sanyo representative or agent.
Is there little gas remaining in the CO
Is the secondary pressure for the CO
specified value of 0.03 MPaG (0.3 kgf/cm
Is the CO gas supply pipe blocked?
2
The CO control method for the Incubator is the ON-OFF method.
2
CO gas is intermittently injected as the gas concentration in the
2
chamber approaches the set value. Injections may be stopped for
periods of approximately 15 seconds, but that is not an error.
When the optional MCO-HL is installed:
When the power is OFF, the electric lock is locked and the outer
door does not open. Either turn ON the power or use the accessory
unlock key to override the electric lock.
During decontamination the outer door is electrically locked and
does not open.
If the MCO-19AIC(UV)/19AIC is being used, is the optional
MCO-HL installed?
If the MCO-19AIC is being used, are the optional MCO-HL and
MCO-19UVS installed?
Is the UV lamp burned out? If the UV lamp is burned out, H
decontamination will not be possible.
Is the H O Generator cable properly connected?
