Description
The attached detector head operator’s manual can be used in conjunction with this
supplement for the 30-0951RK-02, 30-0951RK-HS-02, 30-0951RK-OC-02, or the
30-0951RK-IR-02 flow through adapter. The flow through adapter includes a flowmeter, a
sensor adapter, and a sensor chamber with two compression fittings. A sensor adapter
gasket seals to the 1/2” NPT combustible sensor when installed. A sensor adapter O-ring
seals to all other types of detectors when installed. This O-ring is different for different
types of detectors. A detector chamber O-ring seals the sensor chamber to the sensor
adapter. This O-ring is the same for all versions. A flowmeter is installed in the inlet line.
The flowmeter allows you to view the flow rate through the flow through adapter but
does not let you adjust the flow.
Calibration instructions are the same as those outlined in the attached detector head
manual with the exception that the calibration gas must be connected either to the inlet
fitting tubing or to the pump inlet (if the flow through adapter is on the pressure side of
the pump) as opposed to a calibration cup. Installation instructions are slightly different
and are outlined below.
