Precautions for long-term operation stop

When GC8000 is not used for a long time, stop the supply of power and air according to 3.4
Operation Stop. Continue the supply of carrier gas with the pressure of 1/10 the set value. If the
supply of carrier gas is also stopped, close the main valve of the carrier gas cylinder by sealing
the vent lines to be pressurized.
If carrier gas is hydrogen, the power and purging air must be supplied and the hydrogen limiting
unit must be turned on.
