Battery Charge Status Indicator and Low Battery Alarm
The battery level/alarm indicator (Fig. 13-4) displays the remaining battery charge status. This charge
status indicator mirrors the charge status indicator on the battery. The number of bars illuminated
indicates approximate battery pack charge status remaining: 5 bars = 80-100%, 4 bars = 60-80%, 3
bars = 40-60%, 2 bars = 20-40%, 1 bar = < 20%, 1 bar flashing = < 10%. The charge status indicator
is based on the original charge capacity. It does not recalibrate as the battery ages, and the number
of bars illuminated with a fully charged battery will decrease as the battery naturally loses capacity.
This is a safety feature so that throughout the life of the battery the number of charge status bars lit
consistently indicates approximate run time remaining (with a given system setup and filter loading).
When the low battery alarm sounds, users must immediately exit the hazardous area and replace
the battery.
Filter Load Indicator and Low Flow Alarm
The filter loading indicator (Fig. 13-5) monitors the pressure drop in the system. Increase loading of
contaminants on the filter is indicated by the progressive extinguishing of LEDs in the filter loading
indicator. As the pressure drop increases the motor/blower fan speed increases to compensate. When
the fan is no longer able to compensate and provide adequate airflow, the motor/blower will alarm. A
low flow alarm is indicated by the bottom LED of the filter loading indicator flashing RED. When the
low flow alarm sounds, users must immediately exit the hazardous area and replace the
filter/cartridge and/or the prefilter/spark arrestor.
INSPECTION
Failure to follow these User Instructions may reduce respirator performance, overexpose you to
contaminants, and may result in injury, sickness, or death.
a. Do not use with parts or accessories other than those manufactured by 3M as described in these
User Instructions or on the NIOSH Approval Label for this respirator.
b. The 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 Assembly is one component of an
approved respiratory protection system. Always read and follow all User Instructions supplied with
your 3M headgear and other system components in order to ensure correct system operation.
c. Do not turn off the motor/blower, remove the facepiece or headgear, or reach your hand into
the headgear while inside the contaminated area. This could allow contaminants to enter the
respirator and may result in sickness or death.
Before each entry into a contaminated area, the following inspection must be performed to help ensure
proper function of the respirator system. Respirator systems are intended to help reduce exposures to
certain contaminants and should always be handled with care and fully inspected prior to use. Refer to
the specific assembly subsection of these User Instructions for proper assembly procedures.
1. PAPR system:
• Closely inspect the entire PAPR system including the motor/blower, cover, filter/cartridge,
breathing tube, battery, belt, headgear. Pay particular attention to component connection points
for wear or damage. If parts are missing or damaged, replace them only with 3M™ Versaflo™
Powered Air Purifying Respirator TR-600 replacement parts before proceeding.
2. Filter/cartridge:
• Closely inspect filter/cartridge plastic housing including the corners and latches, outer rectangular
barrier, and inner circular filter seal gasket for cracks, tears, cuts, distortion, indentations or debris.
Replace filter/cartridge if damaged. If the filter/cartridge has been mishandled or dropped, re-inspect
fully. If you have any concerns, contact 3M Technical Service for guidance.
• Ensure the filter/cartridge is properly installed in the PAPR unit.
• If the filter cover is used, the filter/cartridge label must be visible in the filter cover window (Fig. 14).
• If sparks or other hot particles are present, the spark arrestor with filter cover must be in place in
front of the filter/cartridge and prefilter (if used). Failure to use the spark arrestor when needed
may allow the filter to catch fire, or be damaged and allow contaminants to enter the respirator,
and may result in injury, sickness, or death.
