The housing door is hinged on the left side and is secured by two latches on the right side. The flowmeter and status LEDs are visible through a window in the housing door. Four mounting feet are attached to the back of the housing (one at each corner). Use the mounting feet to install the housing to a vertical surface. - Page 9 Main Circuit Board The main circuit board includes the detector/amp terminal strip, interconnect terminal strip, oxygen sensor terminal strip, pump connector, and flowmeter circuit board connector (see Figure 1). Detector/Amp Terminal Strip The detector/amp terminal strip is the upper twelve-point terminal strip in the bottom right corner of the main circuit board.
- Page 10 Status LEDs Two status LEDs are above the flowmeter. They are also visible through the window in the housing door. The green Pilot LED is on when the sample-draw detector is receiving power from the controller. The red Fail LED is on when the sample flow rate is below the low flow level.

Page 11: Installation
Installation This section describes procedures to mount the sample-draw detector in the monitoring environment and wire the sample-draw detector to a controller. Mounting the Sample-Draw Detector Select the mounting site. Consider the following when you select the mounting site: • Is there enough room to open the housing door and make wiring and tubing connections at the bottom of the housing? •... -
Page 12: Connecting The Sample Lines To The Sample-Draw Detector
Connect a length of sample tubing to the other side of the particle filter and route it to the sampling area. 1/ 4” O.D. rigid polypropylene, Teflon, or flexible polyurethane tubing may be used. RKI Instruments, Inc. recommends using either 1/4” O.D. x 1/8” I.D. or 1/4” O.D. x 0.170” I.D. tubing based on your length requirements. -
Page 13: Wiring The Sample-Draw Detector To A Controller
Push 1/4” O.D. rigid polypropylene or rigid Teflon sample tubing into the fitting until it stops. Flexible polyurethane tubing may be used with an appropriate insert. RKI Instruments, Inc. recommends using either 1/4” O.D. x 1/8” I.D. or 1/4” O.D. x 0.170” I.D. tubing based on your length requirements. See “Specifications”... - Page 14 Connect the wires to the applicable detector/transmitter terminal strip at the controller as shown in Figure 4. Refer to the controller operator’s manual and the controller detector head specification sheet for the 35-3001-13-XX for detector/terminal strip connections specific to the controller.

Page 15: Start Up
Start Up This section describes procedures to start up the sample-draw detector and place the sample-draw detector into normal operation. Introducing Incoming Power Complete the installation procedures described earlier in this manual. Verify that the wiring is correct and secure. Refer to the controller operator’s manual for connections at the controller. -
Page 16: Maintenance
Screw the demand flow regulator into the 100% nitrogen calibration cylinder. Connect the calibration tubing from the demand flow regulator to the inlet fitting. Gas will begin to flow. Allow the detector to draw sample for one minute. Verify a reading of 0 ppm or 0% vol for the carbon dioxide channel on the controller display. If the display reading is 0 ppm or 0% vol for the carbon dioxide channel, start up is complete. -
Page 17: Troubleshooting

Page 18: Replacing Components Of The Sample-Draw Detector
If the calibration/response difficulties continue, replace the sensor as described later in this section. If the calibration/response difficulties continue, contact RKI Instruments, Inc. for further instruction. Replacing Components of the Sample-Draw Detector This section includes procedures to replace the IR CO gas sensor, oxygen sensor, hydrophobic filter, and particle filter. -
Page 19: Adjusting The Low Flow Setting
CAUTION: Allow the replacement sensor to warm up for 5 minutes before you continue. 12. Calibrate the replacement sensor as described in “Calibration, Oxygen Sensor” on page 22. Replacing the Hydrophobic Filter Turn off the controller. Turn off power to the controller. Open the housing door of the sample-draw detector. -
Page 20: Removing The Particle Filter's Tubing Stub, If Necessary
NOTE: The pressure switch adjustment screw is accessible through a circular cutout in the flowmeter circuit board. Slowly turn the pressure switch adjustment screw counterclockwise just until the sample-draw detector goes into low flow alarm. Turn the sensor flow control valve’s knob clockwise to increase the flow until the unit is out of low flow alarm when the reset switch is pressed and released. -
Page 21: Calibration Frequency
3 months is adequate for most sample draw detector applications. Unless experience in a particular application dictates otherwise, RKI Instruments, Inc. recommends a calibration frequency of every 3 months for the oxygen detector and every 6 months for the infrared CO detector. -
Page 22: Returning To Normal Operation
Follow the directions in the controller’s operator’s manual for setting the span. Disconnect the sample tubing from the inlet line. Unscrew the regulator from the carbon dioxide calibration cylinder. Returning to Normal Operation Wait approximately one minute to allow the carbon dioxide reading to stabilize. Follow the instructions in the controller’s operator’s manual to exit the calibration mode. -
Page 23: Returning To Normal Operation
Returning to Normal Operation Wait 1 to 2 minutes to allow the oxygen reading at the controller to return to normal, then return the controller to normal operation. NOTE: If you do not allow the oxygen reading to return to normal, then unwanted alarms may occur. Verify that the controller display reading stabilizes at 20.9%. -
