Symptom Items to check and countermeasures
Normal cultures are not possible,
and the CO
2
gas concentration
is suspect.
x Is the ambient air environment around the Incubator normal? Is
there a source of polluted gas in the vicinity?
The CO
2
gas concentration is
slow to recover.
x A HEPA filter is used for the Incubator CO
2
gas piping. If gas
concentration is slow to recover when the CO
2
gas concentration is
normal, it is possible that the HEPA filter may be clogged. Consult a
Sanyo representative or agent.
x Is there little gas remaining in the CO
2
gas cylinder?
x Is the secondary pressure for the CO
2
gas pressure regulator at the
specified value of 0.03 MPaG (0.3 kgf/cm
2
G)?
x Is the CO
2
gas supply pipe blocked?
CO
2
gas is not being injected.
x The CO
2
control method for the Incubator is the ON-OFF method.
CO
2
gas is intermittently injected as the gas concentration in the
chamber approaches the set value. Injections may be stopped for
periods of approximately 15 seconds, but that is not an error.
The outer door does not open. When the optional MCO-HL is installed:
x 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.
x During decontamination the outer door is electrically locked and
does not open.
H
2
O
2
decontamination cannot be
performed.
x If the MCO-19AIC(UV)/19AIC is being used, is the optional
MCO-HL installed?
x If the MCO-19AIC is being used, are the optional MCO-HL and
MCO-19UVS installed?
x Is the UV lamp burned out? If the UV lamp is burned out, H
2
O
2
decontamination will not be possible.
x Is the H
2
O
2
Generator cable properly connected?
x Has the entire bottle of H
2
O
2
Decontamination Reagent been used?
x Has
the upper limit temperature alarm been set to 50qC or higher?
Note: If the problem still has not been solved after trying the above checks and countermeasures, or for
any problems not covered here, contact a Sanyo representative or agent.
