2. Donning Instructions for APR Configuration
WARNING
● Your employer (or you, if you do not
have an employer) is responsible for
establishing that this respirator is
suitable for the user’s application.
● Always read cartridge labels prior to
use to be certain that you have car-
tridges and/or filters that will provide
the required protection. Filters la-
beled for protection against particu-
lates only shall not be used for gas-
es/vapors, and cartridges labeled for
protection against gases/vapors only
shall not be used for particulates.
Both cartridges/filters must be of the
same type.
● Ensure that the o-ring (Item 23, P/N
824014), is in the cap (Item 24, P/N
420020) and the cap plug is securely
seated on the adapter. If the nozzle
plug (Item 26, P/N 962066) is to be
used instead of the cap, be sure
that the Nozzle Gasket (Item 25, P/N
763016) is installed with an inhala-
tion valve.
● The failure to comply with this warn
-
ing may lead to personal injury, ill-
ness, or death.
1. Inspect the respirator as described in Section
IX, Part B.
2. Verify that unused ports are capped as detailed in
Section VII for the APR operational configuration.
3. Verify that two filters and/or cartridges are at

tached to the threaded side connectors of the
facepiece.

tends through each buckle. Fully loosen the
lower straps. For respirators featuring a Head-
net, fully loosen all straps.

NOTE
When properly adjusted, the head strap hub
should be centered on the back of your head
and the lower straps should be below your

sion, the backstrap should be at the nape of
the neck. The Headnet should lie flat on the
head and not bunch up. See Figure 9b.
