4. Carbon Monoxide levels exceeding the removal capacity of the system may be present.

The low temperature catalyst can convert about 60% of any CO in the compressed air stream.

CO amounts above 20 ppm can lead to unconverted CO above the preset alarm point of

10 ppm. In Canada these values would be 10 ppm and 5 ppm preset alarm. Test the carbon

monoxide concentration present in the compressed air system to determine if the input level

of CO exceeds the 3M air purification panel's capacity. Should the input levels exceed the

system's rated capacity, determine the generating source of the carbon monoxide and try to

eliminate the cause.

NOTE: The amber-colored indicator light will light when a low battery condition exists. When

this condition occurs, replace batteries. See carbon monoxide monitor User Instructions.

OPERATING INSTRUCTIONS

The following instructions are intended to serve as a guideline for the use of the 3M™ Portable

Compressed Air Filter and Regulator Panel 256-02-00, with CO Filtration and Monitor. It is not

to be considered all-inclusive, nor is it intended to replace the policy and procedures for each

facility. (Fig. 4 and 5)

W WARNING

Use of equipment described in these User Instructions must be in accordance with applicable

health and safety standards, respirator selection tables contained in such publications as ANSI

Z88.2-1992, CSA Standard Z94.4, or pursuant to the recommendations of an industrial

hygienist. The employer must have a written respirator program in place which is in

accordance with the OSHA respiratory protection standard found in 29 CFR 1910.134 prior to

using any respirator. In Canada, follow CSA Standard Z94.4 or the requirements of the

authority having jurisdiction in your region.

Carbon monoxide monitor will alarm if carbon monoxide concentrations exceed the preset level

(10 ppm USA; 5 ppm Canada). If alarm should sound, remove respirator or activate SCBA and

immediately move to a safe, breathable atmosphere. Have the proper qualified personnel

examine the equipment and make the appropriate corrections before using again. Failure to do

so may result in sickness or death.

The 3M™ Portable Compressed Air Filter and Regulator Panel 256-02-00, with CO Filtration

and Monitor should not be used when the air entering the filtering system is oxygen deficient.

These units will not increase the oxygen content of oxygen deficient air. Use with oxygen

deficient air may result in sickness or death.

The panel should not be used in an Immediately Dangerous to Life or Health atmosphere

(IDLH) unless it is used in conjunction with a back-up escape system or a Self-Contained

Breathing Apparatus/Supplied Air Respirator (SCBA/SAR), where applicable.

Each person using this equipment must read and understand the information in these User

Instructions. Use of this equipment by untrained or unqualified persons, or use that is not in

accordance with these User Instructions, may adversely affect product performance and result

in sickness or death.

Do not use for respiratory protection when atmospheric concentrations of contaminants are

unknown or immediately dangerous to life or health, unless used in conjunction with a back-up

escape system or a self-contained breathing apparatus/supplied air respirator (SCBA/SAR).

W WARNING

Leave work areas immediately if:

– Any part of the system becomes damaged.

– Air flow into the respirator is reduced or stops.

– Breathing becomes difficult.

– Dizziness or other distress occurs; or

– You taste or smell contaminants or an irritation occurs.

Never alter or modify this assembly.

Not for use in any way other than in accordance with the use and maintenance instructions in

this manual.

Do not use if any parts are missing or damaged.

Air supply piping, fittings, and compressors must have the capacity to deliver sufficient air

volume to operate each air regulating valve at the recommended pressure.

If you have any doubts about the applicability of the equipment to your job situation, consult an

industrial hygienist or contact 3M OH&ESD Technical Service toll free in U.S.A.,

1-800-243-4630. In Canada, call Technical Service at 1-800-267-4414.

Carbon Monoxide Monitor

Depending on power option used on monitor, either install batteries and/or optional power source

and turn monitor on for five (5) minute warm-up. Check audible/visual alarms now by pushing

toggle switch up to "TEST" position (refer to monitor User Instructions). The two nine (9) volt

batteries will power the monitor continuously for 30-35 hours. After warm-up period/testing,

check the monitor's calibration.

Calibrate the carbon monoxide monitor as per the calibration instructions in the CO monitor

User Instructions.

The monitor should be calibrated prior to use and every two weeks thereafter for the first month.

Calibrate monitor monthly thereafter if used continuously (daily or weekly). If the monitor is used

on a non-continuous basis, calibrate prior to each use.

Avoid extreme temperature changes; monitor performs best at ambient temperature range 0-110°F

(¯17-43°C). Always calibrate monitor in the temperature range in which it will be used.
