fitting on the back of the Selector.
Set the supply pressure to 380 kPa (55 psi).
9 Connect the Vent fitting on the back of the Selector to the laboratory exhaust
system. When routing the tubing, avoid sharp bends or obstructions. The
exhaust tubing must be able to vent to atmospheric pressure without clogging
or backpressure. Backpressure in the vent line can unbalance the sampling
system and affect repeatability. Handle sample gas exhaust in accordance with
all laboratory and local safety guidelines.
