PREPARING THE C420 PAPR FOR USE
6. Replace the battery cap assembly by threading it
clockwise onto the blower assembly.
AIRFLOW TEST (LESS CANISTERS)
Testing the Operation of the Blower Assembly with the
Airflow Indicator
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. Remove the green seal plugs from the outlet and can-
ister mounting ports of the blower assembly. Do not
discard the plugs. The plugs will be used when storing
the C420 PAPR.
3. Insert the airflow indicator into the blower assembly air
outlet.
4. Push the airflow indicator into the air outlet until it bot-
toms out on the shoulder.
5. Position the blower assembly in an upright position so
the airflow indicator is vertical on top of the blower
assembly.
6. Turn the blower to the “ON” position to verify opera-
tion.
7. Support the blower assembly on a horizontal surface
so that the airflow indicator is approximately vertical.
8. Observe the reading on the airflow indicator. With the
blower assembly running and no canisters installed,
the red ball will rise to the top of the airflow indicator.
9. Turn the blower to the “OFF” position.
10. Remove the airflow indicator
INSTALLING/REPLACING THE CANISTER
• Know the contaminant(s) in the environment before
entering. Always check that the filter canisters are
appropriate for use in the environment. A filter can-
ister which is not designed for the contaminant
present may not provide protection.
• Two new MSA canisters of the same type must be
installed before each use.
• DO NOT reuse canisters. Canisters are intended
for one time use only.
Failure to follow this warning can result in serious per-
sonal injury or death.
Note: The C420 PAPR must be used with two MSA canis-
ters of the same type. Refer to the NIOSH Approval Label
for approval information.
After verifying that the canister type is appropriate for
use in the environment:
1. Verify shelf life expiration date on carton, bag, and
canister label has not been exceeded.
• DO NOT use an expired canister.
• DO NOT use the canister if the bag is opened,
damaged, or missing. The canister must be in its
original packaging prior to use in a contaminated
environment. Do not reuse the canister.
Failure to follow this warning can result in serious per-
sonal injury or death.
2. Remove canisters from the packaging.
3. Inspect the canisters to be sure that they are not dam-
aged.
4. Remove the green protective plugs from the blower
assembly canister inlets and outlet. Do not discard the
plugs. The plugs will be used when storing the C420
PAPR.
5. Inspect the gray gaskets in each of the canister ports.
If either gasket is damaged or missing, replace the
gasket(s) (P/N B- 60026-002).
Note: When replacing the gasket(s), take proper care to
ensure that the canister inlet port threads are not dam-
aged.
DO NOT use a C420 PAPR blower with one or both of
the gaskets damaged or missing. Failure to follow this
warning can result in serious personal injury or death.
6. Remove both canisters from their packaging.
7. Inspect the canisters to be sure that they are not dam-
aged.
Note: Canisters are considered to be in service when they
are removed from their packaging. Canisters are intended
for one time use only.
8. Attach both canisters to the blower assembly by
threading them snugly into the canister ports, hand-
tight.
Replace the canister after each use. Follow the estab-
lished canister change-out schedules to ensure that can-
isters are replaced before breakthrough occurs. When
used at defined occupational exposure limits, the rated
service time cannot be exceeded.
DO NOT over-tighten the canisters. Over-tightening
may distort the gasket resulting in leakage that may
expose the user to substances resulting in serious
personal injury or death.
For CBRN Applications Only
DO NOT use this respirator beyond eight (8) hours after
initial use in an atmosphere containing CBRN agents or
