FTIR Manual
•
A/C power is required to the unit. A/C power is required to the unit (/- 10% OR /-
10% 50/60 Hz). See serial number label on the right-hand side of instrument for voltage requirements.
•
Locate near proper ventilation keeping in mind the maximum length of the exhaust tubing is 25 ft.
•
The DOD64-FTIR requires stable temperature and humidity levels within range to operate properly.
3.2 Sample Tubing
Sample tubing is connected to the DOD64- FTIR on the top the unit. All sample tubes require 1/4” OD x 3/16”
ID Teflon FEP (400 ft max length) which may be purchased from DOD Technologies, INC (See Appendix A).
Fully depress each sample tube into the proper hole when attaching. To detach the tube, push on the collet
while pulling the tubing out.
IMPORTANT: All sample tubing used with the DOD64-FTIR must be 1/4"OD x 3/16"ID FEP Teflon. Use of any
other tubing may damage the DOD64-FTIR and/or cause inaccurate gas concentration readings.
3.2.1 End of Line Particulate Filters
End of line particulate filters must be installed on all sample lines at all times to prevent damage to the unit.
Unused lines must either be plugged or have a filter installed. Filters require regular maintenance
– see
chapter 6.
End of line particulate filters should be purchased from DOD technologies (see appendix A).
IMPORTANT : All points require filtration to prevent dust accumulation in tubing and internal damage to the
DOD64-FTIR. Dust that collects in the tubing or the internal system may cause sample loss and inaccurate
concentration readings.
3.3 Exhaust Tubing
The exhaust line must be 3/8” OD x 1/4” ID tubing with a maximum length of 25 ft. per sample pump.
Excessive lengths will inhibit the flowrate and affect system performance Polyethylene is recommended
although polypropylene or Teflon may also be used. Exhaust tubing may be purchased from DOD
technologies (see appendix A).
3.4 Zero Gas Inlet
The DOD64-FTIR requires a pure Nitrogen source regulated between 20 and 60 PSI. The DOD64-FTIR
periodically uses the inert gas to ensure a clean background. A ¼” OD stainless steel compression fitting is
provided for the nitrogen inlet.
3.5 A/C Power
When connecting the A/C power to the DOD64-FTIR assure that all of the following requirements are met:
•
A building circuit breaker is required
•
The circuit breaker must be installed in a suitable location that is easily reached
•
The circuit breaker must be labeled as the disconnect device for the DOD64-FTIR
•
The circuit break must break both poles.
See system specifications in Appendix C for power requirements.
