■ Procedures to move the dual INJ
Move the dual INJ following the procedures below. Perform backward processes to return it
to its original position.
(1) Set the dual INJ temperature at room temperature or lower and wait until it becomes
40 °C or less.
(2) Turn OFF the power of the GC unit.
(3) Remove the column connected to the dual INJ.
(4) Detach wiring connected to the dual INJ in order to improve workability.
(5) Unfasten the three screws that fasten the dual INJ (Fig. 3.5.2 (a)) and pull the dual INJ
upward.
(Sems screws with a flat washer are used. Be careful not to drop flat washers.)
(6) Take out the heat insulator laid on the bottom of the dual INJ using tweezers or other
similar tools.)
WARNING
Carry out the procedures after the injection port becomes 40 °C or
less to prevent burns.
CAUTION
Some insulation materials include ceramic fibers.
Refer to “When Handling Insulation” of “Introduction” in the GC-2014
Operation manual before you handle these materials.
CAUTION
When cutting a heat insulator, handle a cutting knife, etc. with care.
