PREPARING THE C420 PAPR FOR USE
beyond two (2) hours after initial use in an atmosphere
containing CBRN agents in liquid or mist form; otherwise,
agent permeation may occur.
•
DO NOT replace canisters in a contaminated area.
Be sure to follow applicable decontamination pro-
cedures
•
If the respirator does not perform as specified, it
must not be used until it has been checked by
authorized personnel.
•
Return to a non-contaminated area immediately if
you experience unusual sensations (nausea, dizzi-
ness, eye irritation, unusual odor or taste, exces-
sive fatigue, or difficulty breathing).
Failure to follow this warning can result in serious
personal injury or death.
AIRFLOW TEST (WITH CANISTERS INSTALLED)
Failure to verify proper airflow from the blower assem-
bly may result in reduced performance of the unit,
resulting in serious personal injury or death.
Conducting the Airflow Test
1. Inspect the airflow indicator to verify that the O-ring is
present and in good condition. The red ball must
move freely within the column.
2. Position the C420 PAPR blower in the upright position
so the airflow indicator is vertical on top of the C420
PAPR blower assembly.
3. Insert the airflow indicator into the blower assembly air
outlet. Push the airflow indicator into the air outlet until
it bottoms out on the shoulder.
4. Turn the blower assembly to the “ON” position.
5. Support the blower assembly on a horizontal surface
so that the airflow indicator is approximately vertical.
6. Observe the reading on the airflow indicator.
Acceptable performance shall be indicated by the
position of the red ball being above the line marked on
the outside of the column.
Note:
With fresh canisters and a new battery installed, the
red ball should rise nearly to the top of the airflow indicator.
INSTALLING THE BREATHING TUBE
The FireHawk M7 Responder PAPR utilizes a 6” PAPR
breathing tube extension coupled with either an 18” or
22” APR breathing tube.
Attaching the Breathing Tube assembly to the Blower
1. Remove the green plug from the PAPR breathing tube
extension inlet. Do not discard the plug. The plug will
be used when storing the breathing tube.
2. Inspect the gray gasket in the breathing tube inlet. If
gasket is damaged or missing, replace the gasket (P/N
B-10022-001).
3. Attach the breathing tube inlet to the blower outlet
connection and snugly hand-tighten.
Attaching the PAPR Breathing Tube extension to the
APR Breathing Tube
1. Remove the green plug from the PAPR breathing tube
extension outlet. Do not discard the plug. The plug will
be used when storing the breathing tube.
2. Inspect the green gasket in the APR breathing tube
inlet. If gasket is damaged or missing, replace the
gasket (P/N 10078974).
3. Inspect the green gasket seal around the outside of
the plunger in the APR breathing tube inlet (if using an
APR breathing tube with a plunger). If the gasket is
missing or damaged, do not use the APR breathing
tube.
4. Attach the PAPR breathing tube extension outlet to
the APR breathing tube inlet connection and snugly
hand-tighten.
Attaching the Breathing Tube Assembly to the
Facepiece
1. If attached, remove the black plastic cap from the
facepiece inlet connection.
2. Attach the APR breathing tube outlet to the facepiece
inlet connection and snugly hand-tighten using the
handwheel.
The handwheel on the breathing tube must rotate eas-
ily. If debris has stopped the handwheel from rotating
easily, the faceseal could leak if the breathing tube
gets moved while on the user’s face. Failure to follow
this warning can result in serious personal injury or
death.
Optional Accessory:
Attaching the Spark Covers (Recommended for use in
spark environments)
1. Remove the canisters and spark covers from the
packaging.
2. Attach the canisters to the PAPR.
