CAUTION
If the sealing at the inlet of a cable is not proper, the internal pressure of the pressurized
enclosure does not rise and the power is not supplied to the electronics section.
(5) Mounting columns
The equipment is shipped with a megabore column and capillary column removed to avoid
damage during transportation.
Mount a column delivered as an accessory. When mounting a column, do correct wiring in
reference to the Operation data.
Use leak detecting liquid (such as Snoop manufactured by Swagelok) to confi rm that there is no
leak from joints of the carrier gas line after carrier gas has been supplied.
(6) Checking the inside
Confi rm that there is no loosening of piping, dropping-out of connectors, and loosening of screws
in the main body.
(7) Supplying air
Start the supply of instrument air.
IMPORTANT
Confi rm that the supply pressure is equal to the value described in the Specifi cations. If the
supply pressure is low, the internal pressure of the pressurized enclosure does not rise and the
power is not supplied to the electronics section.
(8) Supplying steam
Start the supply of steam if steam is used at the sample process section. Confi rm that the steam
pressure is equal to the value described in the Specifi cations.
(9) Supplying gases
Start the supply of gases (carrier gas, combustion hydrogen for FID or FPD, etc.)
Confi rm that the supply pressure is equal to the value described in the Specifi cations. After
the indications of the pressure gauge, fl ow rate, and the temperature of the isothermal oven
of GC8000 have become stable, confi rm that they are equal to the values described in the
Operation data.
NOTE
While the power supply is cut, the supply of hydrogen gas into the isothermal oven is stopped
according to the explosionproof standard. To supply hydrogen gas, it is necessary to turn on the
hydrogen limiting unit on the analyzer operation screen after the power has been supplied.
Multiple hydrogen limiting units can be used depending on the specifi cations.
