Startup Test 1 The tubing connection is not tight.
2 Incorrect installation of the absorber
canister.
3 The pressure gauge or oxygen sensor on the
circuit is not installed tightly.
4 There is a leakage in the fresh gas supply.
1 Check the connection on the tubing.
2 Check the installation of the absorber canister.
3 Check the installation of the pressure gauge or
oxygen sensor on circuit.
4 Check the fresh gas supply for leakage
In leakage detection, the
leakage volume is larger than
