2. If the gas supply on the pipeline is
sufficient, but "Air Supply Failure" is
still reported, replace the air supply
inlet assembly (refer to 11.1.8).
3. If the cylinder pressure gauge
indicates that the cylinder pressure is
sufficient, but the status screen
indicates that the pressure is lower
than the normal range, replace the air
cylinder yoke (refer to 11.1.2).
N2O Supply
Failure
Med
N2O supply pressure is
low.
1. Check the connection of the N2O
supply and ensure that the gas supply
is normal. The gas supply pressure on
the AIR pipeline should be within the
range of 280- 600kPa (40-87PSI),
and the cylinder pressure should be
within the range of
4.2-6.0MPa(600-870PSI). Check the
pressures displayed on the pressure
gauge and status screen.
2. If the gas supply on the pipeline is
sufficient, but "N2O Supply Failure"
is still reported, replace the N2O
supply inlet assembly (refer to 8.1.8).
3. If the cylinder pressure gauge
indicates that the cylinder pressure is
sufficient, but the status screen
indicates that the pressure is lower
than the normal range, replace the
N2O cylinder yoke (refer to 11.1.2).
