SURVIVAIR Opti-Fit
™
Convertible Facepiece
10
B. Continuous Flow Supplied Air Respirator(CF-SAR)
1. Side-mounted Breathing Tube
When using the SURVIVAIR Opti-Fit Convertible
as a supplied air respirator (CF-SAR) with side-
mounted breathing tube, the nozzle adapter and
the side port not in use by the breathing tube
must be capped for proper operation. Attach
the nozzle adapter cap (item 24, P/N 420020)
to the nozzle adapter, making sure to hear an
audible click has the cap is pushed into place
(Figure 1).
If a low profile nozzle setup is desired, the noz
-
zle adapter can be removed from the facepiece
and the nozzle plug kit installed in its place. Un-
screw the nozzle adapter from the facepiece by
pressing down on the adapter locking tab from
inside the lens and turning the adapter counter-
clockwise (Figures 2 and 3). Insert the nozzle
gasket (item 25, P/N 763016) into the nozzle
port (Figure 4). Thread in the nozzle plug (item
26, P/N 962066), using a quarter or similar item
in the molded slot to hand-tighten (Figure 5).
Thread one of the provided screw caps (item 27,
P/N 985020) onto the side connector port not
in use by the side-mounted breathing tube and
hand-tighten (Figure 6).

Port (CF-SAR and PAPR Only)
2. Front-mounted Breathing Tube and P100
Escape
When using the SURVIVAIR Opti-Fit Convert-
ible as a supplied air respirator (CF-SAR) with
front-mounted breathing tube, both of the side
connector ports must be capped with the includ-
ed screw caps (item 27, P/N 985020). Thread
the screw caps onto the side connector ports
and hand-tighten (Figure 6). If the facepiece
is to be configured as an CF-SAR with P100
escape, the screw caps are not required, and
a P100 filter cartridge (item 38, P/N 105001)
should be screwed onto each side connector
port. Use of the nozzle adapter is necessary
for connecting the breathing tube and therefore
the low-profile nozzle plug kit cannot be used.
C. Powered Air Purifying Respirator (PAPR)
Both the mask-mounted and belt-mounted powered air
purifying respirator (PAPR) configurations require both
side connector ports to be capped with the included screw
caps (item 27, P/N 985020). Thread the screw caps onto
the side connector ports and hand-tighten (Figure 6).
Use of the nozzle adapter is necessary for connecting
the mask-mounted blower or breathing tube and there-
fore the low-profile nozzle plug kit cannot be used.
WARNING
● Do not attempt to use the SURVIVAIR
Opti-Fit Convertible with both the
nozzle adapter and the side connec
-
tor ports capped.
● Failure to securely cap unused
threaded side port connectors and/
or the front adapter port for the APR,
CF-SAR or PAPR configuration you
are using can allow contaminants
to leak into the respirator and cause
personal injury, illness, or death.
VIII. OPERATING INSTRUCTIONS FOR SPECIFIC
RESPIRATOR CONFIGURATIONS
A. Air Purifying Respirator (APR) Configuration
In addition to the General Warnings listed in Section IV,
the following warnings apply to air purifying respirator
(APR) configurations:
WARNING
● When using this respirator for protec
-
tion against any gas or vapor, includ-
ing gases or vapors with poor warn-
ing properties (e.g., HDI, MDI, or TDI
isocyanates, paint hardeners, etc.),
OSHA 29 CFR 1910.134 requires the
canister to have an end-of-service-
life indicator (ESLI). If the canister
does not have an ESLI, OSHA re-
quires the canister be changed at
intervals derived from a change-out
schedule that is based on objective
information or data that ensures the
canister is changed before the end of
its service life.
● Do not use for protection against
gases or vapors which generate high
heats of reaction with the sorbent
material or against gases or vapors
which are not readily absorbed by
the sorbent (e.g., methanol).
● There are gases and vapors (e.g., ac
-
etone, acetaldehyde, etc.) that have a
boiling point below 149ºF (65ºC). Gas
masks should not be used for protec-
tion against these chemicals
