1.0 System Description

The Nuvair Analyzer Trio measures Oxygen (O2), Carbon Dioxide (CO2), and Carbon Monoxide (CO) levels in supplied gases. All Analyzers are in a water resistant, impact resistant case with a clear cover that allows for viewing of all gas displays, visual alarms and easy access to analyzer controls. This unit is compatible with outdoor and marine environments.

The internal sensors are plumbed together to monitor a single input. Pressurized gases must be regulated down to atmospheric pressure to avoid damage to the analyzer. The sample flow rate must be between 1.0 to 5.0 L/min for an accurate reading.

The Analyzer Trio has visual and optional audible alarms for each of the gases monitored. An audible alarm will sound if any alarm set point is reached.

All analyzers must be calibrated with an appropriate certified calibration gas before operation. Battery powered units will come equipped with a Lithium battery and dedicated charger. The

Lithium battery charger may also be used as a constant power source. If the user chooses to use the charger as a power source for an extended period, it is recommended that the Lithium battery be disconnected from the analyzers to avoid battery damage.

This analyzer is designed for use at atmospheric pressures only. It is not designed for exposures in a hyperbaric chamber. Use of this analyzer in a hyperbaric chamber will result in incorrect readings and may damage the unit.

Although the Analyzer is a rugged instrument, ca reless handling or abuse may result in damage to the Analyzer components resulting in inaccurate gas analysis. Inaccurate gas analysis can lead to serious personal injury or death.

Extreme Gas exposure levels directed at the Analyzer sensors may damage the sensors.

3.0 Requirements for Operation of Analyzer Trio

The Analyzer Trio will require the following connections.

1. Constant gas flow reduced to 1.0 to 5.0 L/min at ATA.

2. Either proper electrical supply to the cord for non-batter y units, or 110Volt, 60Hz AC

Outlet to power the lithium battery charger if so equipped.

3.1 Gas Flow

Before us ing the Analyzer Trio you must connect the analyzer to your compressor system by diverting regulated gas to the analyzer. This will require the use of a flow restrictor to reduce the gas to 1.0 – 5.0 L/Min input. Nuvair sells 3 L/Min flow restrictors for this purpose. See Spares and Accessories sectio n.

3.2 AC Power

Use the provided AC power supply to plug into 110V power. For lithium battery powered analyzers, the battery charger may be used as a constant power

supply. It is recommended that should the user choose to do this, the lithium battery should be disconnected from the system to avoid damage to the cells.

3.3 Gas Sensors

The Analyzer Trio uses three individual analyzers and sensors to measure content in gases of O2, CO2 and CO. The O2, CO2 and CO Sensors are disposable and user-replaceable. The life expectancy of the O2 sensor is 3 years. The life expectancy of the CO sensor is 4 years. The life expectancy of the CO2 sensor is 5 years. The Sensors are designed for use at atmospheric pressure. The sample gas mixture to be analyzed must be regulated and any potential pressure or vacuum must be avoided. Vibration, oil, moisture and particles (contamination) will shorten the life expectancy of sensors.

4.0 Calibration

Analyzer calibration must be verified on a daily basis. Improper calibration may result in an incorrect reading, delivering inaccurate levels of gas being monitored.

Nuvair offers two gas testing kits for the Analyzer Trio. A Helium free gas is

recommended. See addendum for more information.

Regulator Assembly

CO 10 ppm

1000 ppm

Nitrogen Balance

Analyzer calibration mus t be verified on a daily basis. Improper ca libration may result in an incorrect reading, delivering inaccurate levels of gases or moisture being moni tored.

This Analyzer must always be checked with a calibration gas and used with gases regulated and supplied at atmospheric pressure (0 psi). Use of gases at higher pressures may result in incorrect readings and may damage the Analyzer. Inaccurate gas analysis can lead to serious personal injury or death.

Checking Calibration or use of the Analyzer with a low battery may result in inaccurate readings. Inaccurate gas analysis can lead to serious personal injury or death.

If the Analyzer has been subjected to a recent change in ambient temperature, allow it to stabilize for one hour before checking calibration.

Verify calibration on a daily basis. Breathing gas applications require the use of a certified calibration gas with no moisture concentration and flow rate of 1.0-5.0 L/min. The equipm ent to produce this flow is available from Nuvair. See Spares and Accessories section.

To assure the greatest accuracy for other applications, use the calibration gas concentration closest to the expected concentration in the gas being measured.

5.0 O peration of Analyzer Trio

5.1 Turning on Analyzers:

1) Attach a 1.0 to 5.0 L/min flow of ambient air using the battery powered air pump or sample flow from a compressor pumping only ambient air, or calibration gas with a 21% O2 mixture to the Analyzer Trio. This is necessary for the Pro O2 Analyzer to calibrate accurately at startup.

If no other method is available, use a short length of neoprene hose attached to the air input to suck air backward across the sensors. This will draw fresh ambient air into the enclosure. DO NOT blow into the tube as expelled breath contains lower oxygen content and will cause improper calibration.

Page 12 NUVAIR www.nuvair.com

2) Turn on each analyzer by holding down the On/Off button until the display shows the startup cycle.

3) Monitor for the low battery warning on battery powered units. Turn off the analyzers, plug in the battery charger, and turn the analyzers back on if the battery warning appears.

4) Once fully cy cled, the s cr eens should display digits.

Pro Trio Analyzer Manual

5) The values on the displays will continue to change until they settle on the readings for the current gas. Each of the Analyzers performs independently, and will display data in accordance to their individual readings. User must read and consult the instructions for each analyzer section in this ma nual to und er s tand responses of each analyzer.

6) If verifying calibration, you may now attach the calibration test gas and verify the readings are

appropriate for the test gas mix (recommended is 1000ppm CO2, 10ppm CO, 40% O2, Nitrogen

balance provided by Nuvair).

a. If the values do not coincide with the test gas mix, refer to individual analyzer instructions

for calibration and troubleshooting.

Gas, even under moderate pressures, can cause extreme bodily harm. Never allow any gas stream to be directed at any part of your body.

Never expose the sensor to pressures above atmospheric pressure or you may cause damage to the sensor and/or receive false readings. Damaged Sensors will not provide accurate gas analysis. Inaccurate gas analysis can lead to serious personal injury or death.

It is very important that the calibration take place at atmospheric pressure and with calibrated test gas that has no moisture in it.

7.3 Sensor Replacement

The Analyzer Trio has two user changeable sensors The O2 and CO sensors. These sensors have various life expectancies and should be replaced immediately if accuracy is of concern.

The CO2 sensor is currently not user replaceable and the unit must be shipped to Nuvair for service.

If damage occurs, send the analyzer back to Nuvair for inspection and Nuvair will determine if the unit can be repaired or needs to be replaced.

8.0 Programming of the Analyzers in the Analyzer Trio

The proceeding sections will outline the operation of each of the individual analyzers. There are similarities in how each of the analyzers operate and are programmed. Take extra care in reading the sections especially the alarm settings as each has a different program for tripping the alarms. In some cases the alarms are tripped upon reaching the set value and in others the alarm is tripped until the set value is reached. Refer back to the section associated to the analyzer you are programming whenever possible to confirm the proper alarm setting s are bei ng programmed.

9.0 Pro O2 Alarm Analyzer

The Pro O2 Alarm Oxygen analyzer measures oxygen (O2) levels in gases in the range of 0.0 to 100%. The Analyzer is designed to verify O2 concentration in stored gas cylinders, enclosed spaces and with compressors pumping nitrox. When used in breathing gas applications, redundant Analyzers must be used for verification. In diving, for example, one Analyzer must be used to monitor oxygen during breathing gas production and a second independent Analyzer must be used to verify the oxygen content of the breathing gas prior to diver use.

When using the Analyzer for diving applications with mixed gases other than air, you must first obtain proper instruction from a certified diving instructor with a nationally recognized training agency qualified in mixe d gas diving. Improper use of this analyzer may result in incorrect gas analysis which can lead to serious personal injury or death.

The Analyzer is includes an internally mounted Sensor with audible and visual alarms. Large Digital Display and controls are environmentally sealed.

The Analyzer uses a regulated flow of gas within the analyzer to deliver sample gas to the sensor . Pressurized gases must be regulated to avoid damage to the analyzer. Use of this Analyzer in a hyperbaric chamber will void the owner’s warranty.

The Analyzer comes in a high impact storage case. It is ready for use after calibration with appropriate certified calibration gases.

Programming

Although the Analyzer is a rugged instrument, careless handling or abuse may result in damage to the Analyzer resulting in inaccurate gas analysis. Inaccurate gas analysis can lead to serious personal injury or death.

Breathing gas must always be analyzed by two separate Analyzers, with one used for production and one used for analysis after production. Never depend on a single Analyzer during both gas production and delivery. If the Analyzer readings do not agre e, both units must be recalibrated. Inaccurate gas analysis can lead to serious personal injury or death.

9.2 O2 Analyzer Alarm

The Analyzer includes an audible alarm that is activated when the sensor reaches a user programmed minimum % of oxygen and maximum % of oxygen. The alarm will not clear until the concentration of O2 moves into the threshold programmed by the user.

9.3 O2 Analyzer Sensor

The Analyzer uses an electrochemical O2 sensor to measure O2 content in gases. The sensor is disposable and user-replaceable, with a life expectancy of up to 24 months depending on usage. The sensor is designed for use at atmospheric pressure (0 psi). The gas mixture to be analyzed must be regulated accordingly, and any potential for pressure or vacuum must be avoided.

Page 18 NUVAIR www.nuvair.com

Pro Trio Analyzer Manual

9.2. O2 Analyzer Calibration

Oxygen Analyzers must be calibrated before each use. Improper calibration may result in the use of incorrect breathing gas mixtures, which may cause serious injury or death to the person using the gas mixture.

Calibration or use of the Analyzer with a low battery may result in inaccurate readings. Inaccurate gas analysis can lead to serious personal injury or death.

When Analyzer calibration is performed at different atmos pheric conditions than the gas being measured, a calibration correction value may be required. Improper calibration may result in the use of incorrect breathing gas mixtures, which may cause serious injury or death to the person using the gas mixture.

If the Analyzer has been subjected to a recent change in ambient temperature, allow it to stabilize for one hour before checking calibration.

During the warm up time if the oxygen percentage of the mixed gas flow is different from the value of calibration set in the instrument, a failed calibration is obtained and a wrong analysis value will be displayed.

9.4 Pro O2 Calibration Methods

Calibration should always be performed at the same temperature and humidity conditions as the gas being measured. This is not always possible, for example, in a tropical environment where dry breathing gas from a high-pressure scuba cylinder will be measured after Analyzer calibration has been performed in the warm, humid ambient air. Under these conditions a calibration correction value may be required, or dry air must be used for calibration. It may be required for the analyzer to be auto calibrated to a certified calibration gas.

Obtain proper training before attempting special calibration procedures. Improper calibration may result in the use of incorrect bre athing gas mixtures, which may cause serious injury or death to the person using the gas mixture.

To assure the greatest accuracy for other applications, use the calibration gas concentration closest to the expected concentration in the gas being measured.

Page 19 NUVAIR www.nuvair.com

Pro Trio Analyzer Manual

9.5 Pro O2 Analyzer Operation

Prior to each Analyzer use:

1) Connect the battery powered pump. Before switching on and during the warm up, air must be flowing over sensor for proper calibration. The flow rate of air must equal 1.0 –

5.0 L/min.

2) Turn unit on by holding on/off button until display shows “On”, after that the “Att” (Wait) message will be displayed for about 4 seconds, and then the sensor auto-calibration procedure is started.

3) The auto-calibration last about 5 seconds; during this time the display will show the message “CAL” and “Att” alternatively. Be sure during this time the sensor is exposed to an air mix with oxygen percentage as programmed in the O2c (calibration) parameter (SEE PROGRAMMING PROCEDURE). By default, for simplicity, the O2c value is set at 21% that corresponds to the percentage of Oxygen in free air.

4) At the end of the warm up and calibration, the display will continuously show the oxygen content of the air fl ow. The instrument is now ready to read oxygen concentration of the gas.

Gas, even under moderate pressures, can cause extreme bodily harm. Never allow any gas stream to be directed at any part of your body.

Tip: You can check the battery life and current temperature by holding Adjust button for 3

seconds. The display will alternate from battery life to current temperature (Celsius) twice before returning the home screen.

Never expose the sensor to pressures above atmospheric pressure (0 psi) or you may cause damage to the sensor and/or receive false readings. Damaged Sensors will not provide accurate gas analysis. Inaccurate gas analysis can lead to serious personal injury or death.

The oxygen calibration value will be the same value of the calibration set when the instrument is switched on. During the warm up time if the oxygen per centage of the gas flowing across the sensor is a different value of calibration set in the instrument, a failed calibration is obtained and the wrong gas percentage will be displayed. Wrong oxygen analysis may lead to death.

The calibration value of the Pro O2 alarm is factory set at 21% and any adjustments to this value will change the analyzers ability to properly ready the % of oxygen in a gas. A wrong value in this parameter will give a wrong reading of O2 concentration and the instrument will not be accurate. All the analys is concentration shown on the display will be wrong. If you modify this setting you must test the analyzer for accuracy with certified testing gas. Do not modify this value. Wrong oxygen analysis may lead to death.

9.10 Threshold Alarms

Should the Oxygen reading go over the threshold alarms (AL1 or AL2) the instrument will go into alarm mode and will activate the (optional) relays output (open collector max 100mA) and the internal buzzer. The display will show the trespassed alarm and the actual measured value. To stop the audible alarm, press any key. In this event the Pro O2 alarm Analyzer will remain in alarm mode until the analyzed value goes below the alarm. The relay output typically is used to shut down the compressor. Nuvair can supply the necessary components to adapt your compressor to the relay or provide them at the time of install on a new compressor.

9.11 Powering on and warming up

Press the On/Off button for more than one second, until the display shows “on”, after that the “Att” (wait) message will be displayed for about 4 seconds, then the sensor auto-calibration lasts about 5 seconds; during this time the display will show the messages ”CAL” and “Att” alternatively. Be sure that during this time the sensor is exposed to the gas mix with the oxygen percentage as programmed in the “O2c” parameter (see programming procedure). By default the parameter is set at 21% by default that corresponds to the percentage of oxygen in free air, be sure that the air flow at this time across the sensor is 21% oxygen before turning on the analyzer.

During the warm up time if the oxygen percentage of the gas flowing across the sensor is a different value of calibration s et in the instrument, a failed calibration is obtained and the wrong gas percentage will be displayed. Wrong oxygen analysis may lead to death.

The Analyzer includes an audible alarm that is activated when the Sensor reaches 199 ppm CO2 or user programmed level. The alarm will not clear until the concentration of CO2 drops below user programmed level.

10.4 Pro CO2 Sensor

The Analyzer uses an NDIR “non-dispersive infra red” CO2 Sensor to measure CO2 content in gases. The Sensor is only replaceable by the factory, so the unit must be shipped to Nuvair for service. The Sensor is designed for use at atmospheric pressure (0 psi). The gas mixture to be analyzed must be regulated accordingly, and any potential for pressure or vacuum must be avoided.

10.5 Pro CO2 Calibration

Analyzer calibration must be verified on a weekly basis or when moisture and or temperature swings take place. Improper calibra tion may result in an incorrect reading, exposing the user to dangerous levels of Carbon Dioxide. Exposure to Carbon Dioxide can lead to unconsciousness and death.

This Analyzer must always be checked against a calibration gas and used with gases regulated and supplied at atmospheric pressure (0 psi). Use of gases at higher pressures may result in incorrect readings and may damage the Analyzer. Incorrect readings may expose the user to high levels of Carbon Dioxide resulting in personal injury or death.

Checking Calibration or use of the Analyzer with a low battery may result in inaccurate readings. Inaccurate gas analysis can lead to serious personal injury or death.

If the Analyzer has been subjected to a recent change in ambient temperature, allow it to stabilize for one hour before checking calibration.

Verify calibration on a weekly basis or when the ambient temperature or moisture changes dramatically. Breathing gas applications require the use of a certified CO2 cali bration gas and flow rate of 1.0-5.0 L/min. The equipment to produce this flow is available from Nuvair. See Spares and Accessories section.

To assure the greatest accuracy for other applications, use the calibration gas concentration closest to the expected concentration in the gas being measured.

The Pro CO2 can be used to monitor an enclosed space or to analyze a regulated gas sample flow, the contents of a gas cylinder, or the flow from a regulator:

• If monitoring an enclosed space, simply remove the Flow Adapter Cap to expose the Sensor face to the atmosphere and allow 15 seconds for the Display reading to stabilize.

• If analyzing a gas flow, the Sample Flow Method is the preferred method. The flow rate must equal 1.0-5.0 L/min at atmospheric pressure (1 bar). To produce this flow, a Flow Restrictor and Regulator may be required. Contact Nuvair if you need assistance.

10.7 Pro CO2 Sample Flow Method of Checking Calibration (Preferred)

1) Turn on Analyzer with air only flowing through the

Analyzer Trio. Once the analyzer has stabilized you can move on to step 2.

2) Turn the Analyzer off.

3) Attach a Certified calibration gas that best matches

The gas you will be using with the Analyzer Trio and Open gas line to send a 1.0-5.0 L/min flow to the sensor.

4) Turn on the Analyzer and allow reading to stabilize.

Record reading and compare to test gas spec. Once testing is complete and calibration is verified you are able to proceed with using the

analyzer.

Nuvair offers CO2 gas testing kits see addendum for more information.

Testing Gas must not contain Helium for calibration to succeed.

Before using again the instrument, it may be necessary to program again the alarm values, the full scale value, and the conversion value of Carbon Monoxide sensor and gain factor if changed. All the analysis concentration shown on the display would be wrong. Wrong Carbon Monoxide analysis may lead to death.

11.16 Pro CO Sensor Replacement

You should take note of your “Fsc” Number and “nA” Number before installing a new sensor. The “Fsc” number is programmed into the Pro CO Analyzer at the “Fct” and “Fsc” setting. This information will be used to program the Pro CO analyzer after the sensor is installed.

Pro Trio Analyzer Manual

Be sure to dispose of spent, leaking, or damaged Sensors properly, according to local regulations.

Do not swallow (ingest) either the electrolyte from the Sensor or the Sensor itself. The Potassium hydroxide chemical contained in the Sensor will cause severe injury or death. If electrolyte or the Sensor is swallowed, seek medical attention immediately.

If after handling the Analyzer or Sensor, you find that y our fingers or other parts of your body feel “slippery” or the skin or eyes sting, immediately

flush affected area with clean, fresh water for at least 15 minutes. The stinging or slippery sensation is an indication of a leaking Sensor. The Potassium Hydroxide chemical contained in the Sensor can cause severe injury or death. Seek immediate medical attention if eye contact is made or skin stinging persists.

11.17 Handling Pro CO Sensors

Replacement Sensors are supplied in sealed bags. Normally Sensors do not present a health hazard. Before opening the bag, check that the electrolyte has not leaked. However, if electrolyte leakage has occurred, do not open bag. Dispose of Sensor properly or return for replacement. If electrolyte leakage occurs while the Sensor is in service, use rubber gloves and chemical splash goggles for handling. Rinse contaminated surfaces thoroughly with water.

Electrolyte First Aid Procedures

• Ingestion - Drink a large volume of fresh water. Do not induce vomiting. Get immediate medical attention.

• Eye Contact - Flush eyes with clean, fresh water for at least 15 minutes and get medical help immediately.

• Skin Contact - Flush the affected area with clean, fresh water for at least 15 minutes and removed contaminated clothing. If stinging persists get medical attention.
