3M™ Portable Compressed Air Filter and Regulator 256-02-00, with
Carbon Monoxide Filtration and Monitor
Fig. 4
Remove any large volumes of oil/water from supplied air line prior to connecting the system.
Purge air through the system for a minimum of five (5) minutes on initial start-up.
NOTE:
If excessive oil/water is present, install a separate coalescing prefilter such as the
3M™ Coalescing Filter Assembly W-3012 prior to the system inlet. (Fig. 4)
DO NOT
install model 3M™ Portable Compressed Air Filter and Regulator Panel
256-02-00, with CO Filtration and Monitor in a compressed air system where the compressed air
has less than 20% R.H. The fourth stage carbon monoxide filter will not function correctly.
Install the industrial interchange plug into the threaded inlet to the panel. Install all four (4)
industrial interchange quick disconnects into the four (4) threaded outlets from the panel.
Connect the inlet air supply and outlet compressed air hoses.
Pressurize the system and set the regulator to the appropriate pressure required by the respirator air
control device.
Adjust air sample metering valve’s adjustment knob (Fig. 5) so the black floating ball is within
the
green boxed
area etched on valve body. Proper air sample is now being metered to the CO
monitor. Periodically check to be sure ball is floating freely in this area by turning adjustment
knob and noting movement of ball.

To meet NIOSH requirement 42 CFR 84, subpart 84.150 for minimum and maximum airflow
(4-15 cfm, 113-425 lpm), the air control valves approved for use with the 3M respirators must
be operated within the supply pressure ranges and hose lengths stated in their
User Instructions
.
Failure to do so may adversely affect respirator performance and result in sickness or death
.

WARNING
Serious injury could result if the AIR SAMPLE METERING VALVE is not properly adjusted.
Proper sample airflow to CO monitor is required for monitor to give correct CO level readout.
Failure to do so may result in sickness or death.
