RESPIRATOR OPERATIONS CONTINUED

INSPECTION, DISINFECTING AND
CLEANING
Before each use, the unit should be inspected
for the following points. This helps to
determine that the unit is operating as it was
designed and it is suitably protecting the
operator:
1. PX4 AIR ® PAPR SYSTEM: Make a
visual inspection of the entire unit, which
includes the motor housing, filter door
and door cover, filter and pre-filters,
battery, belt and breathing tube. Also
inspect that the correct hood or face
pieces is attached.
2. BATTERY PACK: Check that the battery
has a full charge (see the battery test
strip on the top of the battery, Fig 2.5)
to confirm that there is sufficient charge
for the work period that you need to
accomplish. Make sure that the battery is
securely fitted to the PX4 AIR
3. BREATHING TUBE: Inspect the breathing
tube completely, looking for splits and
cracks in the tube, the fittings are held
securely in the tube and that the O-ring
is in place on the bayonet fitting that
inserts into the PX4 AIR
the breathing tube fits firmly into the PX4
AIR unit and seals without any leaks
®
around the connection.
See Fig 5.3 and 5.4
4. HE FILTER: Inspect the filter casing for
cracks and distortions that will affect the
seal to the PX4 AIR unit. Inspect the
®
filter paper and the seal carefully for any
of the following defects; dirt, cuts and
tears, distortions or indentations. The
seal can be wiped clean with a damp

cloth to remove dirt particles, (do not use
solvents or detergents.) The HE filter
paper must not be cleaned or submersed
in water at any time. Damage to the HE
filter paper will affect its ability to filter
the air and could expose users to harmful
environments. All damaged filters,
pre-filters and spark arresters must be
replaced before using the PX4 AIR
OV/AG/HE FILTER: Do not clean and
reuse the 03-995 filter. This filter is
one-time use only. Dispose of properly
according to government regulations
depending the contaminants it may have
been exposed to.
AIRFLOW METER: Check the ball in the
04-091 airflow meter is moving freely.
Insert the flow meter into the outlet of
the PX4 AIR and rotate ¼ turn to lock in
®
place so that it is sitting vertical. Turn on
the PX4 AIR and let the air stabilize over
®
a 30 second period. With the meter still
in the vertical position check that the ball
is sitting above the minimum flow rate
marker.
WARNING! Do not use the PX4 AIR
the meter does not reach the minimum
