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
NOTE
Use PTFE, glass, stainless steel or
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
1.6.8 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
CAUTION
Connect the exhaust (and vent) fitting on the rear panel to a suitable
vent outside the analyzer area and away from personnel.
