7.2.1 Field Test Kit

A Field Test Kit, CD6-FTK, is needed to complete a CO
CD6-FTK: (1) Gas Cylinders
•
o (1) 34L 5000 ppm carbon dioxide (CO
• Gas regulator 0.2 LPM
About two feet of tubing
•
• CD-6-TH calibration hood
F TK Information
4 2 T
Several detectors can be tested with one FTK. The only limitation is the amount of gas in the cylinder. The 17-liter cylinder has
approximately 85 minutes of a continuous test run time. Replacement cylinders are available. The gas cylinder should be
replaced when the pressure gauge on the regulator shows 25-psi or less or has reached its expiration date.
N ote : For optimum test results it is suggested that the unit be in clean air, green light on, and be in a low ambient air flow.

7.2.2 Field Calibration Kit

A Field Calibration Kit, CD6-FCK, is needed to complete a CO
• CD6-FCK: (2) Gas Cylinders
o (1) 34L 400 ppm carbon dioxide (CO
(1) 34L 5000 ppm carbon dioxide (CO

• Gas regulator 0.2 LPM
• About two feet of tubing
• CD-6-TH calibration hood
F CK Information
4 2 T
Several detectors can be calibrated with one FCK. The only limitation is the amount of gas in the cylinder. The 34-liter cylinder
has approximately 170 minutes of a continuous test run time. Replacement cylinders are available. The gas cylinder should be
replaced when the pressure gauge on the regulator shows 25-psi or less or has reached its expiration date.
Note: For optimum test results it is suggested that the unit be in clean air, green light on, and be in a low ambient air flow.

7.3 Gas Testing

7.3.1 Testing the Fan Relay

1. Remove the Philips screw on the front of the CD-xxH/MC. Remove the front cover.
2. Open the FCK. Connect the 5000 ppm gas cylinder to the regulator.
3. Check the pressure gauge on the regulator. If you have 25-psi or less you will need to replace the gas canister. Check
the expiration date on the cylinder, if it has passed the expiration date the cylinder should be replaced.
4. Assemble regulator, hose, and Test Hood and place the Test Hood over the CO
