Managing the Exhaust Air
To exhaust air from the detector, use the exhaust ports at the rear or at the bottom of the head
mounting box. Remove the appropriate exhaust port plugs and if required, connect an outlet
pipe to the exhaust manifold. In the event the side port is used as an exhaust port, press out the
knockout hole. Remove the plug on the exhaust manifold, located at the divider of the chassis
and the termination card. Run a 25 mm (1 inch) pipe through the side port and insert into the
exhaust manifold, ensuring it is a tight fit.
Note: DO NOT glue this pipe to the exhaust manifold.
Note: Some applications may require the air exhausted from the detector to be returned to
the sampling area.
