Symptom
A large quantity of gas is being
consumed.
Normal cultures are not possible,
and the gas density is suspect.
Gas is not being injected.

Are the outer and inner doors being frequently opened and closed?
Check whether gas is leaking from connectors due to deterioration of the gas tube, or
whether there may be any pinhole leaks. The gas tube is a replaceable part, and it is
recommended that it be replaced once a year.
Is the packing seal for the inner door defective?
Is the access hole open?
Is the ambient air environment around the incubator normal? Is there a source of polluted
gas in the vicinity?
CO
/O
control for the incubator follows the ON-OFF method. Gas is intermittently

injected as the gas density in the chamber approaches the set value. Injections may be
stopped for periods of approximately 15 seconds, but that is not an error.
The gas is not injected until the temperature of the CO
stable, approximately 1 hour after turning ON the power switch or recovering from power
failure.
A HEPA filter is used for the incubator gas piping. If gas density is slow to recover when
the gas pressure is normal, it is possible that the HEPA filter may be clogged. Contact our
sales representative or agent.
Is there little gas remaining in the gas cylinder?
Is the secondary pressure for the gas regulator of CO

Is something pushing against the door switch?
When the optional MCO-170EL is installed:
When the power switch is OFF, the electric lock is locked and the outer door does not
open. Either turn ON the power switch or use the unlock key to override the electric lock.
During decontamination the outer door is electrically locked and does not open.
Are the optional MCO-170UVS, the MCO-HP, the optional MCO-170HB, and the
MCO-170EL installed?
