Manual No. 04143
3.1.7
The preceding precautions also apply to portable
compressors. In addition, in the case of engine-driven
compressors, precautions must be taken to prevent
engine exhaust gases from entering the air intake of the
compressor. Compressor engine exhaust should be piped
to a location safely downwind from the compressor air
intake. Compressors vary in design and operation;
therefore, it is important that users carefully read the
manufacturer's operation and maintenance instructions
before making modifications.
3.1.8
It is the owner's and user's responsibility to make
sure the air supply is safe to breathe. The air supply
includes the compressor, carbon monoxide alarms, and
shutdown devices. An overheated compressor, or one that
is in poor mechanical condition, may produce carbon
monoxide. A carbon monoxide removal or conversion
system may also be used to ensure breathing-air quality.
The maximum allowable level of carbon monoxide in
Grade D breathing air is 10 ppm (parts per million).
3.2
Air Pressure (Outlet Pressure)
3.2.1
Outlet pressure must be set to the pressure for
which the respirator(s) is designed. Refer to the
respirator owner’s manual to find the approved pressure
setting. All respirators connected to the filter must be
approved to operate within the same pressure range.
WARNING
Failure to maintain the minimum pressure at the
CPF filter outlet (point of attachment) may
reduce air flow below the minimum flow
required by OSHA. Reduced air flow may result
in ingress of hazardous toxic dust, subjecting
the user to immediate health and life
threatening poisoning and subsequent
respiratory disease.
4.0 SETUP
NOTE: The filter must be setup and placed in an area
that permits monitoring of the outlet pressure,
access to the drain, and removal of the cap for filter
cartridge replacement.
4.1 Breathing-Air
Connections
4.1.1
Filters can be configured for either left or right
hand inlet. If it is more convenient to have the air inlet on
the opposite side, swap the plug and inlet connector.
This is usually required only with fixed installations.
4.1.2
The following instructions explain air
connections using hose as the air supply line; hard
piping may be used in place of hose. If the filter is hard-
piped, place an isolation valve in the piping to enable
depressurization for service.
4.1.3
Connect an air fitting that is compatible with the
air supply hose, from an air source that meets OSHA
requirements for respirable air, to either of the inlet ports
on the side of the filter. The port’s thread size is 1" NPT.
4.1.4
Connect a 3/4" ID or larger air hose, from a
respirable air source to the inlet fitting. Maximum inlet
pressure is 150 psi.
DANGER
Do not connect the CPF Filter to bottled air or
any other air source that does not have a
pressure-reducing valve that lowers pressure to
maximum of 150 psi. Failure to comply with this
warning will cause the CPF filter to explode
under the high pressure of bottled air, and
could cause severe injury or death.
5.0 ADJUSTMENTS
5.1 Outlet
Pressure
5.1.1
Outlet pressure must be set to the pressure for
which the respirator(s) is approved. The respirator’s
approved pressure may be found in the respirator’s
owner’s manual. All respirators connected to a filter must
be approved to operate within the same pressure range.
5.1.2
Adjust pressure with respirators attached and
prior to donning the respirator.
5.1.3
To adjust pressure: pull the regulator knob out,
and turn clockwise to increase pressure or counter-
clockwise to decrease. Pressure will register on the
gauge
.
Once operating pressure is set, push the knob in
to lock.
6.0 MAINTENANCE
6.1 Draining
6.1.1
Drain moisture from the filter every four hours.
More frequent draining may be required in humid
environments. The drain petcock is located on the
bottom of the filter body.
