CHARGING THE BATTERY PACK
UNPACKING & INSPECTION
The OptimAir Mask-Mounted PAPR kit
consists of the following components:
motor-blower
battery pack
support belt
charger
cable
facepiece
storage plug
filter
Thoroughly inspect all components
of the respirator before the device is
used. Read and observe all NIOSH
approval limitations as they apply to
using the OptimAir Mask-Mounted
PAPR.
Do not use this storage plug while
working in a contaminated atmos-
phere. Doing so will compromise
respirator performance and void
NIOSH approval. Use plug only dur-
ing decontamination and storage to
help prevent debris from coming out
of cartridge. Failure to follow this
warning can result in overexposure
and serious personal injury.
Do not drop the OptimAir Mask-
Mounted PAPR. The battery pack
can be damaged by impact. The
case can be cracked and could
allow water into the pack. If the unit
is dropped, inspect the case for
cracks. If the motor blower no
longer operates from the compro-
mised battery pack, the battery
pack must be replaced.
The motor-blower housing can be
damaged by impact. The blower
impeller can be loosened or the
motor shaft can be bent. If the unit is
dropped, check the case for cracks.
Listen closely to the sound of the
motor. If the impeller binds or rattles,
or if air output is reduced, the entire
motor-blower must be replaced.
CHARGING THE BATTERY PACK
The battery pack must be fully
charged before the respirator is first
used. Use only the P/N 10090981 bat-
tery charger from MSA. Other chargers
can damage the battery due to internal
wiring differences or incorrect charging
rates.
The battery pack should be stored at a
temperature range of 50°F to 85°F. If
the battery pack has been stored in a
“fully charged” condition for more than
one week, the battery pack should be
charged until a full charge is indicated.
Do not charge the battery pack
where there are explosive concen-
trations of combustible gases,
vapors, or mists. An explosion or
fire can result. Replace the charger
if the cord is damaged or worn, or if
