ONLY use genuine Nextteq LLC replacement parts when performing any maintenance
procedures provided in this manual. Failure to do so may seriously impair instrument
performance. Repair or alteration of the product beyond the scope of these maintenance
instructions, or by anyone other than an authorized Nextteq LLC serviceman, will void
the warranty, and could cause the product to fail to perform as designed and persons who
rely on this product for their safety could sustain severe personal injury or death.
Review the interferences for each detector tube used in conjunction with this equipment.
Observe any temperature of humidity corrections for the detector tubes used with this
equipment.
Use ONLY Gastec detector tubes designed for use with the Airtec System. DO NOT use
other brands of detector tubes with the Airtec tube holder.
Detector tubes contain chemical reagents. DO NOT ingest or allow children to ingest
tube contents.
Avoid cuts from broken detector tubes.
The tube holder may have to be held in place during tube installation.
Excessive stretching of the tube holder will shorten the useful life of the tube holder.
The regulator incorporated in this equipment has a maximum inlet pressure of 3000 psig.
DO NOT exceed this pressure.
The flow meter will not operate properly if the regulator inlet pressure drops below 50
psig.
The Airtec System should be checked for leaks on a routine basis. Cracks or leaks in the
flow meter cover tube can affect flow meter accuracy. Leaks between the flow meter and
the tube holder will result in low detector tube readings.
The flow meter is calibrated for breathing air. It is not accurate when applied to other
gases.
The preset regulator delivery pressure of 50 psig should not be altered. The maximum
safe pressure for the flow meter is 75 psig.
DO NOT over tighten ANY threaded connection. Over tightening the regulator fitting
can cause distortion of the threads and/or seating surface. Over tightening the flow meter
needle valve will damage fine internal threads and sensitive metering seat.
