The filter and regulator panel must be installed a minimum of 25 feet away from the compressor.
The actual distance required from the compressor shall be determined by the temperature of the air.
The air supply temperature at the filter should be 35-150°F (2-65°C) for maximum efficiency.
Conditioning equipment may be necessary, prior to the filter, to achieve this temperature
range. (Fig. 4)
The filter and regulator panel is used to adjust the air pressure supplied to the air control devices
of a respiratory protection system. Consult instructions on your particular air control device for
pressure requirements.
The filter and regulator panel comes with a 3M™ Carbon Monoxide Monitor designed to provide
continuous, direct read CO monitoring. The carbon monoxide monitor in the filter and regulator
panel is CSA certified intrinsically safe for Class 1, Div. I, Groups A, B, C & D Hazardous
Locations when utilizing the two 9 volt batteries to power the monitor. See the carbon monoxide
monitor
User Instructions
. If the optional AC power adapter is used, the power cable can be
routed out through an existing vent hole or an additional hole can be drilled for this cord.
The filter and regulator panel is supplied with an industrial interchange plug (1/2" body size, 3/4" MPT)
at the inlet and eight (8) industrial interchange quick-disconnects (1/4" body size, 3/8" MPT) at
the outlet.
The filter cartridges have an average life expectancy of one (1) to two (2) months
(or approximately 160-320 hours, depending on the quality of the air in your compressed air lines)
under normal conditions. The frequency of filter change will depend on the quality of the
incoming compressed air and how much the panel is used. All three (3) filters should be changed
at the same time.
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:
1. Carbon monoxide levels exceeding a predetermined alarm set level (10 ppm USA, 5 ppm
Canada) are passing through the 3M filter and regulator panel. Examine the air compressor air
intake for CO concentration. Eliminate the source of CO or move the air intake to a position
where CO free air is available. Do not use respiratory protection systems until CO levels are
below the predetermined alarm set level (10 ppm USA, 5 ppm Canada).
2. Monitor is out of calibration. Calibrate per the carbon monoxide monitor

.
3. Monitor sensor may be bad. See carbon monoxide monitor

for
replacement procedure.
NOTE:
The amber-colored indicator light will light when a low battery condition exists.
When this condition occurs, replace batteries. See carbon monoxide monitor

WARNING
The intrinsic safety of the carbon monoxide monitor is voided when remote alarm is used.
The intrinsic safety of the carbon monoxide monitor is voided when the 110-120 volt AC
adapter is used.
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.
