This manual contains the information you need to install the QuickSwap
accessory and run a checkout method. It does not supply full discussions of
control parameters, the other checkout methods, or how to operate the gas
chromatograph (GC) or the mass selective detector (MSD). See the following
for more information.
The User CD
Contains this manual, the Reference Manual, two flow calculation utilities,
QuickSwap-adapted versions of the MSD checkout methods in both loadable
and printable form, and other information.
The Reference Manual
Describes the parameters (including choice of restrictor) that govern
QuickSwap, how to convert existing methods for QuickSwap, backflushing
with QuickSwap, maintenance, and replacement parts.
GC and MSD manuals
How to operate the two devices that are connected by QuickSwap. Includes
safety information.

6 QuickSwap Installation and Startup
Plumbing the Purge Gas
Plumbing the Purge Gas
For new systems, plumbing is best done by ordering Option 885. The factory
will then make the correct purge gas line installation.
If you prefer to do the installation yourself, or if you are retrofitting
QuickSwap to an existing system, see the following instructions.
Use extreme care to avoid contaminating the purge gas line with oven
insulation during the installation.
In either case, the purge gas line must be in place before you start the
QuickSwap installation.
6850 Series II GC
To install the purge gas line:
1Cool the GC oven and turn the power off.
2If necessary, mount the G3349B Auxiliary EPC on the back of the GC using
the instructions provided with the kit.
3Confirm that Channel #5 of the EPC has an output restrictor with a brown
dot or line. If not, replace it with the FID Air flow restrictor (part number
19231-60610) from the Aux EPC supplies kit.
4Connect the purge gas supply and check for leaks.
WARNING Hydrogen is both a fire and explosion hazard when mixed with air. For this reason,
hydrogen must not be used as the purge gas.
WARNING Cool the column oven, inlet, and MSD transfer line before starting. They may be hot
enough to cause burns.

5Locate the external gas line hole on the left side of the GC (Figure 1).
6There is a hole in the oven inside wall that lines up with the external gas
line access hole. Use a thin tool to make a hole through the insulation
connecting the two holes. Do not use any of the tubing to make the hole
through the insulation.
7Uncoil the purge gas tubing (Aux #5). Place a plastic cap or two thicknesses
of aluminum foil over the end of the tubing to keep insulation fragments
out. Push the capped tubing into the external hole and into the oven. Feed
enough tubing through the hole so that you can install a fitting on the end.
8Remove the cap or foil and install the 1/8-inch to 1/16-inch reducing union
from the kit on the end of the tubing inside the oven.
WARNING The insulation around the oven is made of refractory ceramic fibers. To avoid inhaling
fiber particles, we recommend the following safety procedures: ventilate your work
area; wear long sleeves, gloves, safety glasses, and a disposable dust/mist respirator;
dispose of insulation in a sealed plastic bag; wash your hands with mild soap and cold
water after handling the insulation.

9Pull excess tubing out of the oven leaving 2 to 3 inches inside. Route the
tubing along the side of the GC to the EPC module.
6890 GC
These instructions assume that the purge gas is supplied by an EPC module.
PCM instructions are similar.
The purge gas supply line should enter the oven in the upper left corner and
terminate in a reducing union.
To install the purge gas line:
1Cool the GC oven and turn the power off.
2Raise and remove the GC detector cover to expose the oven top. Remove the
detector cover, the pneumatics cover, and the RFI cover.
3If necessary, install the G1570A Auxiliary EPC into the GC using the
instructions provided with the kit.
4Confirm that Channel #5 of the EPC has an output restrictor with a brown
dot or line. If not, replace it with the FID Air flow restrictor (part number
19231-60610) from the Aux EPC supplies kit.
5Connect the purge gas supply and check for leaks.
CAUTION In the next step, be careful to avoid creating a kink in the tubing where it exits the GC
side panel and turns toward the EPC module.
WARNING Hydrogen is both a fire and explosion hazard when mixed with air. For this reason,
hydrogen must not be used as the purge gas.
WARNING Cool the column oven, inlet, and MSD transfer line before starting. They may be hot
enough to cause burns.

6Remove the valve box cutout using a side cutter (Figure 2).
7Install the 6890 valve box blank provided in the QuickSwap supplies and
spares kit using the two screws. Note that the notch in the blank should be
on the left and toward the back.
8Locate the tubing from channel 5 of the EPC module. Unroll the tubing
through the slot in front of the EPC module, then along the back of the oven
top toward the hole in the valve box blank.
WARNING The insulation around the oven is made of refractory ceramic fibers. To avoid inhaling
fiber particles, we recommend the following safety procedures: ventilate your work
area; wear long sleeves, gloves, safety glasses, and a disposable dust/mist respirator;
dispose of insulation in a sealed plastic bag; wash your hands with mild soap and cold
water after handling the insulation.

CAUTION Avoid kinks or sharp bends in the tubing.

9If the tubing is not already capped, cover the free end to keep insulation out
of the tubing.
10 Use a screwdriver to create a hole through the insulation and into the GC
oven.
11 Feed the tubing down through the hole and into the oven.
12 Re-install the covers.
13 Remove the protective cap from the end of the tubing and attach the
reducing union from the kit.
14 Bend the tubing neatly into the left back corner of the oven, leaving enough
tubing inside the oven so you can later connect to the QuickSwap union.
15 Push excess tubing up on top of the oven and arrange neatly.
