3000 Micro GC Operating Manual
Proceed as follows:
1 Connect the Carrier Gas Cylinder Recharge Kit (PN PNU-2058) to the supply
tank via the CGA-580 fitting. See
Figure 8-44 . To avoid leaks, tighten the
connections securely.
2 Make sure the needle valve of the Carrier Gas Cylinder Recharge Kit is fully
closed by turning the needle valve clockwise until it is firmly seated. See
Figure
8-44 .
Figure 8-44 Cylinder recharging kit setup
3 Partially open the valve on the supply tank. No gas should flow.
4 Loosely connect the 1/8 in. tube from the Carrier Gas Cylinder Recharge Kit to
the CARRIER FILL (Swagelok) port on the Portable 3000 Micro GC back
panel. See
Figure 8-45 .

5 Partially open the needle valve on the Carrier Gas Cylinder Recharge Kit and
listen for gas leaking through the loose 1/8 in. fitting on the back panel. This
purges the Carrier Gas Cylinder Recharge Kit transfer lines so that no air enters
Portable 3000 Micro GC.
6 After the transfer lines have been sufficiently purged (about fifteen seconds),
tighten the 1/8 in. fitting on the back panel of Portable 3000 Micro GC.
