Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A
1.6.6 Sample Gas Connection
1/4" O.D. PTFE tubing is needed to connect the sample source to the analyzer. See Figure 1-4.
NOTE
Use PTFE, glass, stainless steel or non-reactive materials for
sample gas connections.
NOTE
Use vent line when sampling from pressurized manifold - sample
pressure should not exceed
±
2 mm Hg.
1.6.7 Zero/Span Valve Connections
Zero air and span gas manifolds should supply their respective gases in excess of 800cc/min
demand of the analyzer. The manifold should be vented to the outside atmosphere and be of
sufficient length and diameter to prevent back diffusion and pressure effects. See Figure 1-4.
1.6.8 Exhaust Connections
A single 1/4" O.D. tube should be connected from the analyzer sample exhaust to an area outside
of the room the analyzer occupies. The maximum length of the exhaust line should not exceed 3
meters (See Figure 1-4).
CAUTION
Connect the exhaust (and vent) fitting on the rear panel to a suitable
vent outside the analyzer area and away from personnel.
