respirator hose length. 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.

Pressure Conversion Kit
4.2.3.1
This optional accessory kit contains parts and
instructions to convert an Apollo 20 respirator from low
pressure (for use with an ambient air pump) to high
pressure (Grade “D” Compressed Air). The kit is listed in
Section 10.1.
5.0 OPERATION
WARNING
Except for emergency evacuation when the use
of the respirator hinders escape, keep the
respirator on and leave the respirator-use area
immediately if any of the following occur:
Any part of the respirator system
becomes damaged
Any air monitoring alarm is activated
Air flow 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
5.1
Prior to use, thoroughly inspect and clean the
helmet, breathing tube, respirator hose, air entry ports,
and fittings of all dust and debris. Inspect the helmet
suspension and if necessary replace it per Section 9.6.
5.2
Begin the operation of the ambient air pump per
the manufacturer’s instructions.
5.3
Check air pressure at the point of attachment.
Set the pressure within the minimum and maximum
pressures assigned in Section 4.2. Pressure must be set
with the respirator connected.
5.4
Inspect all safety and breathing equipment used
in conjunction with the respirator as recommended by
the manufacturer.
5.5
Inspect respirator hoses and connections for
tightness and leaks.
5.6
Don the respirator in a clean non-hazardous
environment, free of contaminants, where the air is safe
to breathe.
5.7
When donning and removing the respirator,
keep it upright to prevent dust and abrasive from falling
inside. Holding the chin strap while donning the helmet
will make it easier to position it once the helmet is on.
5.8
Position the chin strap so it fits comfortably
under the chin.
5.9
Position the knit cuff on the inner collar so that it
fits snugly around the neck in turtleneck fashion, and
without any interference from clothing or long hair. When
correctly positioned, the smaller elastic end of the collar
must face up.
WARNING
Correct placement of the inner collar is critical
for providing the protection for which the
respirator is designed. The collar must be
positioned and maintained without any
interference from items such as hair, facial hair,
or shirt collars, between the inner collar and
user’s neck.
5.10
Pull the cape down to fully extend it and connect
the four elastic straps (two on each side) under the
arms, and tighten using the slides provided.
5.11
Put on the belt and constant-flow connector over
the cape. Buckle the belt around the waist, and tighten it
by pulling the belt end through the buckle insert.
