Inspect the package contents for shipping damage and ensure all components are present. The product should be
inspected before each use following the procedures in the Inspection section of these User Instructions.

Assembly

Battery Pack

The TR-300 PAPR assembly is not intrinsically safe. Do not use in flammable or explosive atmospheres. Doing
so may result in serious injury or death.
Always correctly use and maintain the lithium ion battery packs. Failure to do so may cause fire or explosion or
could adversely affect respirator performance and result in injury, sickness, or death.
a. Do not charge batteries with unapproved chargers, in enclosed cabinets without ventilation, in hazardous
locations, or near sources of high heat.
b. Charge in an area free of combustible material and readily monitored.
c. Do not immerse.
d. Do not use, charge, or store batteries outside the recommended temperature limits.
Refer to the 3M™ Versaflo™ Power Air Purifying Respirator TR-300 Chargers and Battery Packs User Instructions for
additional information on proper battery pack use and maintenance. Battery packs should be charged immediately and
fully upon receipt and after each use.

Charge the battery pack

1. Inspect battery pack initially and prior to each charge cycle. If cracks or damage to the case is noted do not charge
the battery pack. Properly dispose of the battery pack and replace.
2. Place chargers in a cool, well ventilated location free of particulates or other airborne contamination. Charge in an
area free of combustible material and readily monitored.
3. Power source:
TR-341N Single Station Battery Charger:
° Insert the battery pack into the TR-340 charging cradle by sliding the back end of the battery pack in first. Push
down to click the front end into place (Fig. 1).
° Insert the TR-941N power cord into the cradle (Fig. 1a).
TR-944N 4-Station Battery Charger:
° Insert the TR-340 into one of the charging ports on the TR-944N and slide back to lock into place (Fig. 1b).
° Insert the battery pack into the TR-340 cradle as described above. (NOTE: The TR-941N power cord is not used with
the TR-340, when the 4 Station Charger is used.) Ensure the power cord supplied with the TR-944N kit is plugged
into the 4 station base. You may charge any combination of up to 4 TR-330 or TR-332 battery packs simultaneously.
NOTE: The TR-340 and TR-944N do not use the same power cord. Use only the cord supplied with your
charger kit.
