30-0951RK-IR1S8

Flow Through Adapter www.rkiinstruments.com

Description

The attached detector head operator’s manual can be used in conjunction with this supplement for the 30-0951RK-IR1S8 flow through adapter. The flow through adapter includes a sensor adapter and a sensor chamber with two compression fittings. A sensor adapter O-ring seals to the detector when installed. A detector chamber O-ring seals the sensor chamber to the sensor adapter. 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 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 installed 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 8 mm OD rigid metal tubing such as copper, aluminum, or stainless steel. The inlet fitting is located on the side of the sensor chamber and the exhaust fitting is located on the bottom. Insert the desired length of tubing into each fitting and tighten the fittings so that the ferrules crimp onto the

tubing.

5.

Install appropriate device(s) (pump, aspirator, etc.) to draw sample to the detector.

NOTE: Be sure to use the inlet and exhaust ports as intended to ensure correct sensor response and to allow any accumulated liquid to drain out the bottom of the flow through adapter.

6.

Calibrate the detector head as described in the attached manual and in the next section.

NOTE: Calibrate the detector head with the flow through adapter installed to ensure an accurate reading.

Calibration

A demand flow regulator should be used for calibration.

1.

Follow the calibration instructions outlined in the attached detector head manual.

2.

When the instructions call for applying gas, connect the cylinder.

• If you are drawing sample through the system, connect the cylinder to the inlet fitting of the flow through adapter.

• If you are pushing sample through the system, connect the cylinder to the pump inlet.

3.

Perform a calibration as outlined in the attached detector head manual.

4.

When the instructions call for removing the gas, disconnect the cylinder.
