monoxide removal or conversion system may also be used
to ensure breathing air quality. The maximum allowable
presence of carbon monoxide in Grade D breathing air is
10 parts per million (ppm).

Air Volume and Pressure
4.2.1
A pressure regulator and gauge must be installed
at the point where the respirator hose is attached to the air
source. The Clemco CPF Filter with regulator meets this
requirement if the inlet pressure does not exceed 125 psi.
See typical installation, Figure 1.
! DANGER
Do not connect the Apollo Respirator or CPF
Filter, or any other regulator or filter, to bottled air
that does not have a pressure reducing valve that
reduces pressure to maximum of 125 psi (65 to
100 psi for the respirator only). Failure to comply
with this warning will cause devices rated at
lower pressures to explode under the high pres-
sure of bottled air. Such an explosion could cause
severe injury or death.
4.2.2
The respirator must be supplied with 15 cfm (cubic
feet per minute) of Grade D breathing air at 65 to 100 psi
(pounds per square inch). When using an alternate Cool-
Air Tube or Climate Control Tube, the respirator must be
supplied with 20 cfm of Grade D breathing air at 90 to 100
psi.
4.2.3
The pressure regulator must be adjusted to 65 to
100 psi. Refer to the table in Section 4.2.4 to determine the
minimum pressure, based on the total length of respirator
hose, and choice of air control device. Adjust the pressure
with the respirator hose and respirator attached. If the
regulator is adjusted with static pressure (no air flow),
pressure may drop below the required pressure when the
respirator is connected, and may result in low air flow.
Setting the pressure as instructed will provide a minimum
of 7 cfm to the respirator.
4.2.4
Use the table below to determine the minimum
pressure setting and maximum respirator hose length,
based on the air control device as shown in Section 1.7.2.

! WARNING
The compressor must provide adequate output,
and the plumbing between the compressor and
the point of attaching the respirator hose must
have sufficient capacity to supply the volume of
air at the pressure required (as stated in Section
4.2.2). Restricted air flow will cause discomfort to
the user, and may result in ingress of hazardous
and toxic dust, subjecting the user to health and
life threatening toxic poisoning and long term
respiratory disease and death.

OPERATION
! WARNING
With the respirator on, leave the blast area
immediately if any of the following conditions
occur:
• Any part of the respirator system becomes
damaged.
• Any air monitoring alarm is activated.
• Airflow into the respirator is reduced or
stops.
• Breathing becomes difficult.
• At the first sign of dizziness, nausea, fever,
illness or injury.
• Any contamination is noted by taste, smell
or vision inside the respirator.
• Vision becomes impaired.
• Any irritation is noted.
