Attach the 370XA bracket to the pole by sliding the plastic inserts
onto the pole and bolting the two U-bolts through the inserts and
the holes in the bracket. The base of the bracket should be 40 inches
from the ground to make the operator interface easy to use.

Secure to the oor with four ½ - inch or ⅜ - inch cement anchors.
The cement foundation should be able to support the weight of the
GC (45 lbs) and its accessories, as well as any other utilities that may
be installed.
If supplying your own pole, it should be four inches in diameter and
at least 55 inches tall.
Mount the bracket on the pole.

1. Install 10 mm or ⅜ in anchors (not supplied) suitable to
anchor the weight of the GC (approx. 20 kg or 45 lbs) as per
the drawing. Use the bracket as a guide to locate the anchors
correctly before drilling the holes. The threads of the anchors
should protrude from the wall by 40 mm (1½ in).
2. Mount the 370XA bracket to the wall anchors and tighten the
nuts. Ensure that the bracket is attached rmly to the wall.
2. Maneuver the GC to insert the two top bolts into the eyelets
of the mounting bracket and allow the bolts to drop down and
hold the GC loosely on the bracket.

Mount the bracket on the wall.
Set the GC onto the bracket.
1. Use a 6 mm hex wrench to screw the top two bolts into the back
of the 370XA without the washers, leaving ½-inch (1.5 cm) of
thread showing.
3. Screw in the two bottom bolts through the mounting bracket
with the washers on. The at washer should be against the
bracket , and the spring washer between the at washer and the
bolt head. Hand tighten these two bolts so that they secure the
GC in place.
4. One at a time, remove the top bolts, put on the washers, and
screw the bolts into the back of the GC and hand tighten.

Step 2 – Sample Handling System and Gas Line Connections
1Mount the single stream sample plate
1. Use the two one-inch bolts and a 5/32 hex wrench to screw the
large mounting bar tightly to the left side of the plate with the
angled foot facing the edge of the plate.
NOTE: To install a multi-stream sample system, please refer to the instructions provided in the sample system installation kit.
2. Use the two half-inch bolts and a 5/32 hex wrench to screw the
small mounting bar loosely to the right side of the plate with
the angled foot facing the edge of the plate.
3. Angle the plate onto the left side of the GC so that the large
mounting block ts behind the left edge of the cut-out. Swing
the right side of the plate around until it attaches to the right
side of the cut-out.
4. Slide the small mounting bar to the right so that it ts behind
the right edge of the cut-out. Tighten the small mounting
block's screws.

2. Connect the atmospheric vents to a vent line of at least ⅜''
diameter that is routed to the atmosphere in a safe area to
ensure there is no back-pressure created on the vents.
NOTE:
The ows out of the vents are:
Sample Vent – 10 to 50 cc/min of sample gas for approximately
3/12 minutes of the 4 minute cycle.
Measure vent –Continuous ow of less than 10 cc/min of carrier
gas and 10 cc of sample gas per analysis cycle.
Sample Bypass – Continuous ow of 150 to 200 cc/min of sample
gas.
2Connect the gas lines
1. Using the tubing supplied with the sample system, connect the
stream, actuation, and calibration gases from the sample plate
to the manifold block (as shown).
3. Open the carrier gas bottle valves and set the regulator to
90 PSIG (6.2 BarG).
4. Open the calibration gas bottle valves and set to
15 PSIG (1 BarG).
5. Open the sample probe valves and set the sample pressure to
20 PSIG (1.4 BarG).
6. Leak check all lines with liquid leak-check solution.
7. Open the sample and calibration valves on the sample panel
and leak-check up to the ttings on the 370XA inlet manifold.

Step 3 – Wiring
1. Route the power supply lines through the lower left or right cable entry – which ever is the most convenient.
2. Connect power wires to TB8. DO NOT APPLY POWER YET.
3. Route the communication wiring through the lower right cable entry. If additional separation of wiring is required, use the upper right
cable entry for the additional signal wiring.
4. Connect the signal wiring as shown in the diagrams below.
