Breathing Air Quality Positi on Statement

The responsibility for the quality of breathing air rests with the user. Compliance with federal, state, or local regulati ons are the responsibility of the user and this recommendati on does not supersede any existing rules, regulati ons, or laws which may apply. Breathing air fi ltrati on products meet or exceed CGA Grade-D specifi cati ons for air quality as adopted by Federal OSHA. Compressor air quality standards meet or exceed

OSHA 1910.134 requirements. When the components are used in accordance with the manufacturer's instructi ons and recommendati ons, the "system" meets or exceeds federal regulati ons presently in force. It is incumbent upon the user to comply with any changes in the regulati ons or law which may occur in future situati ons.

The air supply compressor should be located in a safe, clean ambient air environment. This "safe" locati on should be tested periodically using proper instruments to ensure clean ambient air quality on a consistent basis. Total system Grade-D air quality should be tested at the ti me of initi al setup. If the compressor is moved, retesti ng air quality is recommended. Should the locati on or environment signifi cantly change, the air quality should be retested. The compressor fi lters and oil level should be checked daily and changed when contaminated or when the maximum number of "run" hours is achieved.

This series of air fi ltrati on units should be used according to the recommendati ons specifi ed in the manual. The standard fi ltrati on package is not explosion-proof and should be located in a non-explosive environment. (An intrinsically safe model is available, please contact the factory for informati on.) The carbon monoxide monitor should be calibrated monthly or if the accuracy of the monitor is in questi on. System air quality should be tested for, but not limited to, the following Grade-D air components:

CO - Carbon Monoxide

O2 - Oxygen

CO2 - Carbon Dioxide

H2O - Water (Moisture Content)

Hydrocarbons (Oil Mist)

Total Parti culates

The maximum allowable level of these air quality components varies depending on

Grade-D or E requirements. Contact sales for a copy of the latest standards.

Our Breathing Air compressors and fi ltrati on systems meet all of the following federal specifi cati ons when used and serviced in accordance with our instructi ons.

Federal OSHA 29 CFR 1910.134

CARBON MONOXIDE MONITOR OVERVIEW

The monitor will analyze the air sample and display the CO concentrati on in parts per million (ppm). The system’s green “NORMAL” operati on light will illuminate and the red “HIGH CO” light will fl icker approximately every second when the CO level is below 10ppm (5ppm Canadian). If the CO concentrati on level exceeds the alarm set point, the green “NORMAL” light will turn off , the red “HIGH CO” light will illuminate, the audible alarm will sound, and the remote alarm connecti ons will energize. Once the CO concentrati on levels drop below the alarm set point, all alarm indicators will deacti vate and the unit will return to “NORMAL” operati on.

BREATHER BOX™ SETUP AND OPERATION

Note: Always operate the Breather Box™ in the upright positi on. Failure to comply may result in one or all

of the following:

1) Auto drains will not functi on properly. This may result in the contaminati on of the CO monitor and cause

oil/water to be passed through respirator hose and into the worker’s mask.

2) Auto drains may become clogged.

3) Filters may accumulate moisture and/or contaminati on.

STEP 1)

Secure a primary air source of sufficient air flow and discharge pres sure. The number and type of respirators being used determines the flow rate and pressure required.

STEP 2)

Check airline monitor for fresh 9 volt batteries and turn unit on. Connect the remote signal cable, 115 VAC plug, and air sample hose to the monitor.

Place the “ON/OFF/TEST” switch to the “ON” position. Allow 30 seconds for the readout to stabilize. If a reading other than “00” is displayed, cali bration of the monitor may be necessary. See calibration procedure.

Note: Remote signal cable does not apply to BB15 series.

STEP 3)

Connect the extension cord to a 115 VAC receptacle.

Note: The CO monitor can run off the 9 volt batteries if AC power is not available.

STEP 4)

Connect the optional remote alarm (DC only) assembly to the remote alarm jack.

Note: This step does not apply to BB15 series.

STEP 5)

Close the flowmeter by turning the control knob fully clockwise. Do not over-tighten.

STEP 6)

Connect the air source, 150 psi max., to the inlet fitting.

STEP 7)

Hold the “ON/OFF/TEST” switch in the “TEST” position. All local and remote audi ble/visual indicators will activate. If indicators do not activate, check all electrical connections, then call factory repair dept.

Note: An alarm function test can be performed at any time by lifting the “ON/

OFF/TEST” switch to the “TEST” position.

STEP 8)

Attach desired respirators and hoses to the quick connect couplings.

Note: Some models may not have respirator connections. They may be ordered with NPT outlets for connection to points of attachment.

STEP 9)

Adjust the outlet pressure to the setting recommended by the respirator man ufacturer. Turn the knob clockwise to increase pressure, counterclockwise to decrease pressure.

STEP 10)

Adjust CO monitor air sample flow rate by turning the flowmeter control knob coun terclockwise until the ball hovers between 50 and 100 cc/min. The box is now ready for operation.

The monitor will analyze the air sample and display the CO concentration in parts per million (ppm). The system’s green “NORMAL” operation light will illuminate, and the red “HIGH CO” light will flicker faintly approximately every second when the CO level is below 10ppm (5ppm Canadian).

When the CO concentration level exceeds the alarm set point, the green “NORMAL” light will turn off, the red “HIGH CO” light illuminates, the audible alarm will sound, and the remote alarm connections will energize.

When CO concentrations drop below the alarm set point, all alarm indicators will deac tivate and return to normal operation.

10

SHUTDOWN

1) Make sure all personnel have egressed from the work area.

2) Shut off air source to the box.

3) Remove air pressure from the box by pulling the relief valve ring out.

4) Turn the CO monitor off . Do not remove the 9 volt batt eries. These are used to maintain a

bias voltage to the sensor; this keeps the sensor ready for immediate use.

5) Disconnect airline hoses.

6) Install dust caps if applicable.

SYSTEM MAINTENANCE

CAUTION: Always depressurize the system before performing service.

Filter Housing/Bowls : Periodic cleaning of the polycarbonate bowls may become necessary. Remove the auto drains and clean the bowls with a mild soapy soluti on. The auto drains may also be cleaned with a mild soapy soluti on at this ti me. Dry and reinstall into the fi lter housing.

Filter Change : The fi ltrati on system consists of fi lter change indicators which will gradually change from green to orange when fi lter life is spent.

Note : Air must be fl owing through the fi lters before the fi lter change indicators will functi on.

With system pressurized, close inlet ond outlet ball valves. Release the fi lter trio pressure by pressing the manual drain assembly to the side. Remove the bowl assemblies by releasing the lock ring.

Calibrati on : Monitor calibrati on should be done monthly or whenever the reading may be questi onable. A calibrati on date sti cker should be affi xed for future reference. To obtain an accurate calibrati on, we recommend the use of Air Systems calibrati on kits.

Part Number :

BBK-10 Canadian calibrati on kit for CO monitor; 10ppm CO, zero air, regulator and case - 17 liter size.

STEP 5)

Reassemble monitor and reinstall in unit. Connect all cables and air sam ple hose. Allow monitor to stabilize

30 minutes to 1 hour and recalibrate.

12

CALIBRATION PROCEDURE

Do not use inert gases to zero the monitor. This will cause premature failure of the sensor.

CO Monitor Zero Adjustment

To zero the monitor, follow the steps below. Zero calibrati on gas should be used to properly “zero” the monitor and assure that a valid calibrati on is achieved. If zero adjustment cannot be made as indicated, sensor replacement may be necessary. Aft er each monitor adjustment outlined in the steps, allow ti me for the changes to stabilize.

STEP 1)

Place the “ON/OFF/TEST” switch in the “ON” positi on.

STEP 6)

Turn the knob on the regulator counterclockwise to allow the fl ow of gas thru the hose. Verify fl ow of gas thru the hose via touch or sound.

STEP 2)

Allow 30 seconds for the readout to stabilize. The green indicator will illuminate.

STEP 3)

Hold the “ON/OFF/TEST” switch in the “TEST” positi on. The following will occur:

Audible alarm will sound

Green LED will fl ash

Amber Low Batt ery indicator on monitor will

illuminate

Red LED will be on

This test ensures the circuitry is operable and conti nuity to the sensor is proper. Release the switch.

STEP 7)

Att ach the clear tubing with the male plug to the air sample inlet on the monitor.

STEP 4)

Remove the air sample inlet tube.

STEP 8)

Allow digital readout to stabilize approximately 15-

30 seconds.

STEP 9)

Adjust the “zero” adjustment screw (clockwise to increase or counterclockwise to decrease) unti l a reading of “00” is obtained.

STEP 5)

Install regulator on the zero air cylinder reference gas.

STEP 10)

Turn the regulator off and disconnect the regulatorfrom the zero gas cylinder.

13

CALIBRATION PROCEDURE

CO Monitor Span Adjustment

Use only 10-20ppm CO gas for calibrati on. Using a higher concentrati on may decrease accuracy at lower scale readings. Note: 10ppm gas must be used to sati sfy Canadian calibrati on requirements.

STEP 1)

Install regulator on the CO calibrati on gas cylinder.

STEP 4)

Allow digital readout to stabilize 15-30 seconds.

STEP 5)

Adjust the “span” adjustment screw (clockwise to increase or counterclockwise to decrease) unti l the digital readout reads the same as the concentrati on

(ppm) as printed on the calibrati on gas cylinder.

STEP 2)

Turn the knob on the regulator counterclockwise to allow the fl ow of gas thru the hose. Verify fl ow of gas thru the hose via touch or sound.

STEP 3)

Connect the plug to the air sample inlet on the monitor.

STEP 6)

Turn the regulator off and repeat the “zero” adjustment procedure. The digital readout should return to a “00” reading.

The monitor is now calibrated and should be recalibrated monthly or if accuracy is questi onable. Check local requirements and recalibrate as required.
