Charge The Battery Pack - 3M Versaflo TR-600 Series User Instructions

The following guidelines will help maximize useful life of the 3M battery packs. Contact 3M Technical Service for additional guidance if needed.
• Battery should be charged immediately and fully upon receipt.
!
• Battery should be fully recharged at least every 9-12 months.
• Power supply: 3M™ Battery Charger Cradle TR-640 must only be used with 3M™ Power Supply TR-941N. The 3M™ 4-Station Battery Charger
Tray TR-944N must only be used with the power supply included with it. To ensure safe charging of batteries, only use combinations as specified.
• Charging temperature: The battery pack must have an internal temperature above 32°F (0°C) and below 104°F (40°C) in order to charge. Outside
of this temperature range, the charger will indicate a temperature fault (slow flash amber LED error) and will not charge. Charging will start when
battery pack temperature is within range. Optimal internal battery charging temperature is 68°F to 77°F (20°C to 25°C). Repeated charging outside the
optimal temperature range will reduce battery run time and cycle life.
• Run time: A fully charged battery pack run time will be reduced when used at environmental temperature extremes, as filter loading increases, at
higher selected airflows, and due to naturally occurring aging of the battery pack.
• When to recharge: Do not force the PAPR to restart after auto-shutdown following a low battery alarm. Doing so may 'deep discharge' the battery,
which will permanently reduce available capacity. Recharging a battery at the end of each day's use, even if the battery is not fully discharged, will
help prolong the life of the battery.
• In-use temperature range: Do not expose battery pack to temperatures above 129°F (54°C). The TR-600 motor blower battery alarm will activate if
battery pack temperature reaches 130°F (55°C) while motor blower is in use. If this happens, immediately leave the contaminated area. The motor
blower will shut down when the internal battery temperature reaches 140°F (60°C).
• Serviceable parts: There are no user serviceable parts inside either the battery pack case or the chargers. Do not attempt to open; doing so will
void the warranty.
• Disposal: To properly dispose of the battery packs follow local regulations or contact call2recycle.org at 1-877-723-1297. The charger contains
electronic components. Dispose of according to local and government regulations.

OPERATING INSTRUCTIONS
1. The 3M™ Battery Packs TR-630, TR-632, chargers, and the TR-600 PAPR assemblies are not intrinsically safe. Do not use in flammable or
explosive atmospheres. Doing so may result in serious injury or death.
2. 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.
NOTE: Immediately charge battery packs upon receipt and after each use.

Charge the battery pack

1. Inspect battery pack. If cracks or damage are 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.
• Optimal charging temperature range: 68°F to 77°F (20°C to 25°C).
• Full charging temperature range: 32°F to 104°F (0°C to 40°C). Do not charge outside of this range.
3. Charging cradle setup:
• 3M™ Single Station Battery Charger TR-641N: Insert the DC supply cord from the 3M™ Power Supply TR-941N into the cradle (Fig. 1a). Plug
the power cord into an AC power source (100-240V), such as a wall outlet.
• 3M™ 4-Station Battery Charger Tray TR-944N: Insert the 3M™ Battery Charger Cradle TR-640 into one of the charging ports on the TR-944N
and slide back to lock into place (Fig. 1b). (NOTE: the TR-941N power cord is not used with the TR-640, when the 4-station Charger is used.)
Insert the DC supply cord supplied with the kit into the 4-station base. Plug the power cord into an AC power source (100-240V), such as a wall
outlet. You may charge any combination of up to four 3M™ Battery Packs simultaneously.
NOTE: The 3M™ Battery Charger Cradle TR-640 and 3M™ 4-Station Battery Charger Tray TR-944N do not use the same power supply. Use only the
power supply supplied with your charger kit.
