Installation

The attached detector head operator’s manual can be used in conjunction with this
supplement for the 30-0951RK-01, 30-0951RK-HS-01, 30-0951RK-OC-01, or the
30-0951RK-IR-01 flow through adapter. The flow through adapter includes a sensor
adapter and a sensor chamber with two compression fittings. A sensor adapter gasket
seals to the 1/ 2” NPT combust ible sens or wh en i nstal led. A sens or ada pter O -ring seal s 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. Calibration instructions are the same as those outlined
in the attached detector head manual with the exception that the calibration ga s must be

connected either to the inlet fitting tubing or pump inlet as opposed to a calibration cup.

Installation instructions are slightly different and are outlined below.

1. The flow through adapter is normally shipped in stalled to the detector. If it is not
installed, screw the flow through adapter onto the detector tightening firmly by hand.

CAUTION: Make sure the flow through adapter is installed tightly and after installation is

complete, verify that the flow through adapter is still tightened firmly onto the
detector to avoid possible leaks.

2. If necessary, re-orient the sensor chamber so the inlet fitting faces away from the
mounting surface by unscrewing the three thumbscrews, rotating the sensor chamber,
and tightening the three thumbscrews.

3. Install and startup the detector head as described in the detector head operator’s
manual. Make sure there is sufficient room between the detector and the mounting
surface for the flow through adapter.

4. The inlet and exhaust fittings accept 1/4” OD rigid metal tubing such as copper,
