TABLE PACKING WARNINGS OF CONTENTS LIST READ AND UNDERSTAND ALL WARNINGS BEFORE USE Read and understand ALL warnings before using this product. Failure to read, understand, and comply with ALL warnings could result in property damage, severe personal injury or death. Read and understand ALL applicable Federal, State, and Local environmental health and safety laws and regulations, including OSHA.

TABLE PACKING WARNINGS OF CONTENTS LIST 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.
TABLE PACKING WARNINGS OF CONTENTS LIST The system should always be stored in a clean dry place when not in use. Some bottled breathing air is prepared by blending liquid nitrogen and liquid oxygen at 79% and 21% respectively. Oxygen content should be monitored when this type of breathing air is used. DO NOT attempt to remove the Airtec regulator from the breathing air source while the regulator is under pressure. Take precautions against water entry into the regulator.
TABLE PACKING WARNINGS OF CONTENTS LIST READ CAREFULLY BEFORE USING THIS PRODUCT Some safety rules associated with compressed air systems are listed below. This equipment is pressurized when in service and can cause personal injury if it is improperly used or maintained. DO NOT attempt to operate this equipment if any part is damaged or broken. DO NOT tamper with the preset regulator adjusting screws as over pressurization could occur.
SECTION PACKING I: Introduction LIST 1.1 MONITORING BREATHING AIR A chemical plant worker inspecting a tank car cleaning operation, a fire fighter donning his self-contained breathing apparatus, and a SCUBA diver on a weekend holiday all face a common situation. Each is putting his or her life on the line by hooking up to a temporary air supply.

SECTION SECTION PACKING II: Airtec I: Introduction Kit LIST Components 1.2 AIRTEC KIT Your Airtec Kit includes the following components: Regulator, Regulator Gauge, Flow Meter, Tube Holder 1.3 AIRTEC DETECTOR TUBES The Airtec Kit is designed for use with the following Gastec Tubes: Carbon Monoxide, Carbon Dioxide, Nitrogen Oxides, Oil Mist, Water Vapor WARNING Use only the Gastec tubes listed above.
SECTION SECTIONI:I: Introduction Introduction 1.4 ACCURACY & CALIBRATION The Airtec System when used in accordance with tube instructions provides an accuracy of ±25%. The flow meter is factory calibrated and should not require recalibration with normal use and proper care of the unit. Should a calibration check be required, the unit may be returned to the factory, or calibration may be checked using a soap film bubble meter.

SECTION SECTION II: Airtec I: Introduction Kit Components _________________________________ 2.1 REGULATOR The regulator is a two-stage breathing air regulator. It is preset at the factory to deliver 50 psig to the flow meter. It is precision-machined from solid brass stock. Internal parts are protected by a double filter system of sintered Monel metal, backed by sintered bronze. A preset safety device prevents overloading. Warning The regulator has a maximum inlet pressure of 3000 psig.
SECTIONPACKING II: Airtec Kit LIST Components _______________________________________________________________________ 2.3 TUBE HOLDER The tube holder is designed to hold a Gastec detector tube leak-tight in series with the regulator flow meter. Important Use only Gastec Airtec tubes. Other Gastec tubes are NOT calibrated for use with this type of sample delivery. See Section 1.3 (page 12) for further information.
SECTION SECTION PACKING II:III: Airtec Testing Kit LIST Components Procedure 3.1 INTRODUCTION The Airtec kit is equipped with a CGA 346 fitting for breathing air bottles. This fitting is specified by the compressed Gas Association to be used only for breathing air bottles. The Airtec Kit may also be used for filtration and carbon monoxide removal devices, by providing a quick disconnect near the respirator hookup. See Figure 3 (page 15). Refer to section 3.
SECTION SECTION PACKING II:III: Airtec Testing Kit LIST Components Procedure 5) Break the end off of a fresh tube and install it in the tube holder. Note the directional arrow. Hold the tube holder in place with your free hand during stretching. The arrow should point away from the flow meter (or downward in the normal configuration). The tube is installed by first inserting the upper end into the holder then stretching the holder over the lower end of the tube.
SECTION SECTION PACKING II:III: Airtec Testing Kit LIST Components Procedure ________________________________________________________________________ 3.3 COMPRESSOR SYSTEMS The Airtec Kit may also be used for monitoring compressed breathing air systems. See Figure 3 (page 15). The Airtec System should be placed as close as possible to the respirator hookup. The line pressure must be above 50 psig in order for the flow meter to work properly.
SECTION IV: PACKING Maintenance LIST & Troubleshooting 4.1 TESTING FOR LEAKS The Airtec System will provide maximum accuracy only if the system is leak free. Test for leaks by applying a soap solution to system connections while the unit is under normal operating pressure. If a leak is detected, tighten the fitting slightly and retest. Repeat until the leak is stopped. Warning Do not over tighten connections. Return unit to factory if leaks persist.
SECTION IV: PACKING Maintenance LIST & Troubleshooting SECTION V: Sampling Tips Tips for Tube Reading The following items will be helpful when reading and interpreting the Airtec detector tubes. 1.) Always read the tubes and record the results immediately after testing. In some cases stains may fade or “crawl” within a few hours. 2.) A tube may never be reused, even after a zero reading. 3.) The oil mist tube is normally used at 500 scc/min for 40 minutes.
SECTION PACKING II: Airtec Kit LIST Components SECTION V: Sampling Tips 5.) Excessive water vapor (i.e., >3 mg/l of H2O) may cause the reagent in the oil mist tube (PN 109AD) to stain yellow although the reading will not be affected. Run the water vapor test before running the oil mist test. The recommended testing priority is listed below. 1st…..H2O 2nd….CO2 3rd…..CO 4th…..Oil Mist 6.) The proper stain color for oil mist tube is dark brown. Other color changes should be disregarded. 7.
