CO 2 gas isintermittently 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 anerror. The gas is not injected until the temperature of the CO 2 sensor becomes stable enoughapprox. 1 hour, after turning ON the power switch or recovering from power failure.The CO 2 gas density is slow torecover. A HEPA filter is used for the incubator CO 2 gas piping. If gas density is slow to recoverwhen the CO 2 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 CO 2 gas cylinder? Is the secondary pressure for the gas regulator at the specified value of 0.03 MPa(G)(0.3 kgf/cm2 (G), 4.3 psi(G))? Is the gas tube blocked? Is the duct securely attached?
