GENERAL OPERATION MANUAL

WARNING: The MST Breathing Air Panel Models

:

1) WILL NOT remove Carbon Monoxide.

2) SHALL NOT be used when the air entering the filtering system is oxygen deficient. The

MST Breathing Air Panel will not increase the oxygen content of the air.

3) SHALL NOT be used in an Immediately Dangerous to Life and Health Atmosphere

(IDLH) unless it is used in conjunction with a Back-Up Escape system or a supplied air

Self-Contained Breathing Apparatus (SCBA), where applicable.

4) CARBON MONOXIDE MONITOR will alarm if Carbon Monoxide levels exceed requirements for Grade "D" Breathing Air set forth by OSHA/CSA. If alarm should sound, remove respirator or activate SCBA and immediately move to safe breathable atmosphere. Have the proper qualified personnel examine the equipment and make the appropriate corrections before using again.

5) SHALL NOT have air inlet pressure greater than 150 PSIG static (10.4bar). Personal injury could result.

6) SHALL NOT have air outlet pressure that exceeds Manufacturers' Respirator/Hose

Assembly pressure requirements. Personal injury could result.

The MST Breathing Air Panel is a Four Stage Filtration System designed to remove or reduce select contaminates found in compressed air lines while monitoring for carbon monoxide through the CO

Monitor. The Breathing Air Panel can be connected directly to shop air from a standard compressed air source to help provide breathing quality air to face masks, helmets, hoods and other supplied air breathing apparatus.

GENERAL FILTER SYSTEM DESCRIPTION

(Refer to Figure No.1)

Air entering the MST Breathing Air Panel at the inlet (A) is usually contaminated with oil, water, dirt, rust, scale and gaseous Hydrocarbons. As the air passes through the First Stage (B) of the MST

Prefilter, particulate matter is trapped and retained down to 0.3 microns. The air then enters the

Second Stage (C) of the Prefilter which coalesces liquid contaminates down to 0.75 microns with an efficiency rating of 99.97% (meets Underwriters Laboratories Specification UL 586 for High

Efficiency, Particulate, Air Filter Units). The liquid contaminates are trapped in the lower chamber of the prefilter and expelled out through the Automatic Float Drain (D). The Third and Fourth

Stages (E & F) contain a deep bed of odor absorbing activated charcoal which collects various gaseous Hydrocarbons (such as oil fumes, benzene, etc.). The air is then passed through the Air

Pressure Regulator (G), which is used to adjust the air pressure going to the respirator. A sample of the filtered air is taken at (H) and passed through the Carbon Monoxide Monitor (I). The Carbon

Monoxide Monitor continuously checks the carbon monoxide levels per OSHA/CSA requirements and digitally displays the amount present in PPM, (parts per million). An audible alarm/strobe will alert operators if levels of carbon monoxide exceed OSHA/CSA requirements.

GENERAL INSTRUCTIONS

The MST Breathing Air Panel, a compressed air purifier, when used in accordance with the following instructions, will remove or reduce selected contaminants from compressed air lines.

******************************************************************************

WARNING:

The MST Breathing Air Panels should not be used when the air entering the

filter is oxygen deficient (air with a low oxygen content). The MST Breathing Air Panel will not increase the oxygen content of oxygen deficient air.

******************************************************************************

MST, Inc. strongly recommends that a complete safety program be initiated to ensure that the respiratory air is in compliance with all OSHA standards and other applicable laws regulating the use of supplied air respiratory systems. MST, Inc. recommends that the air quality be tested upon installation and periodically re-tested to ensure that the minimum requirements for breathing air are maintained.

******************************************************************************

WARNING:

The MST Breathing Air Panels will not remove Carbon Monoxide.

******************************************************************************

The Carbon Monoxide Monitor in the Breathing Air Panel Model BA100BA-S1 is a standard nonintrinsically safe version. For purposes of this paragraph, "non-intrinsically safe" monitor is defined as one which must not be used in explosive atmospheres. Refer to the Monitor Information Manual for charging, calibration, and operating instructions. MST, Inc. will not assume any liability for accidents or personal injury resulting from the improper use of this equipment. Service on this equipment should only be performed by qualified personnel.

This system is to be used only by trained qualified personnel in accordance with a respirator program as outlined in OSHA Regulation 29 CFR 1910.134(b).

The air supply entering The MST Breathing Air Panel must meet two (2) criteria to ensure maximum efficiency of the MST filter system:

1) Temperature range should be between 68-150 o

F (20-65 o

C)

2) Liquid size range should be between 2-8 microns.

Conditioning equipment may be necessary, prior to the filter, to achieve this temperature range and bulk liquid removal.

******************************************************************************

WARNING:

Maximum pressure supplied to this unit IS NOT to exceed 150 PSIG. Personal

injury could result.

******************************************************************************

The Regulator 80075 is used to adjust the air pressure supplied to the operator(s) to maintain the correct air exchange inside the mask. Consult instructions on your particular breathing mask or hood for pressure requirements per NIOSH.

******************************************************************************

WARNING:

DO NOT Exceed mask and hose assembly manufacturer's requirements for

outlet pressure. Personal injury could result.

******************************************************************************

The filter cartridges used in the Breathing Air Panel Model BA100BA-S1 have an average life expectancy of (1) one month, (depending on the quality of the air in your compressed air lines) under normal conditions. MST, Inc. recommends changing all three (3) filter cartridges after one month of use unless conditions warrant more or less frequent replacement.

******************************************************************************

WARNING: If the Monitor's alarm should sound, remove mask or hood immediately and move to a safe breathable atmosphere. Have a proper qualified personnel examine the equipment and make the appropriate corrections before using again.

******************************************************************************

The Carbon Monoxide Alarm will sound to alert the operator that a problem has developed. The

Monitor Alarm will sound due to one or more of the following conditions:

A) Carbon Monoxide levels exceeding a pre-determined alarm set level is passing through the

Breathing Air Panel. The Breathing Air Panel does not remove or reduce the Carbon Monoxide content in the compressed air. Examine the air compressor, the air compressor intake air quality, and the complete system. Have the proper qualified personnel make the appropriate corrections before using again.

B) Monitor out of Calibration. Calibrate Carbon Monoxide Monitor as outlined in the Monitor

Information Manual.

C) The monitor's carbon monoxide sensor may be bad. See the Monitor Manual for further maintenance on monitor.

AIR SAMPLE TO

MONITOR ADJUSTMENT

******************************************************************************

WARNING : SERIOUS INJURY could result if the AIR SAMPLE METERING VALVE is not properly adjusted. Proper sample air flow to ‘CO’ monitor is required for monitor to give correct ‘CO’ level readout.

******************************************************************************

AIR SAMPLE METERING VALVE ADJUSTMENT

A) Pressurize system and set regulator for proper air flow to respirator(s).

B) Adjust Air Sample Metering Valve’s adjustment knob so the black floating ball is within the
