HEADGEAR
The 3M™ Versao™ Powered Air Purifying Respirator TR-800 is approved for use with many 3M™ Headgear options.
Refer to the headgear User Instructions for information on attaching and donning the headgear to be used, and to determine
assigned protection factor (APF) for the complete respiratory protection system. Consult 3M Technical Data Bulletin #175 for
additional information on APFs and supporting test data.
OPERATING INSTRUCTIONS
Power 3M™ Versao™ Powered Air Purifying Respirator TR-800 on
• Press and hold the smaller, yellow power button (Fig. 12-1) for 1 second. The unit will turn on and perform a
self-diagnostic. The ow level, lter loading and battery charge indictors will blink, and the auditory alarm will sound.
Battery indicator (Fig. 12-4) will show current charge status of the battery pack. Filter indicator will show remaining
capacity of the lter (Fig. 12-5). Continuous blinking and/or sounding of any alarm indicates a fault condition
that must be corrected prior to use of the respirator system. If auditory alarm or visual indicators do not
activate at start-up, do not use system. Remove from service and see your supervisor.
Select airow
• There are three user selectable airow settings- standard, medium, and high ow. The motor/blower will start at
the standard ow setting. Pressing and holding the larger yellow ow control button (Fig. 12-2) for 1 second will
cycle the motor/blower to the next of three ow settings. One beep and ow LED on the ow setting indicator (Fig.
12-3) indicates standard ow, two beeps and two ow LEDs indicate medium ow, three beeps and three ow LEDs
indicate high ow. Pressing the ow control button once more cycles back to the standard ow setting.
Power 3M™ Versao™ Powered Air Purifying Respirator TR-800 off
• Press and hold yellow power button for 2 seconds (Fig. 12-1).

Display Sleep Mode
To conserve battery power, the display will go into ‘sleep mode’ after 30 seconds from the last button press. The ow speed
indicator will periodically blink with the current ow setting (Fig. 12-3). To wake up the display, momentarily press any
display button.
Battery Charge Status Indicator and Low Battery Alarm
The battery level/alarm indicator (Fig. 12-4) 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
ashing = < 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 lter loading). When the low battery alarm sounds, users
must immediately exit the hazardous area and replace the battery in an area where intrinsically safe equipment is
not required. Never bring the TR-830 battery alone into an area which is potentially ammable or explosive. Doing so may
result in serious injury or death.
Filter Load Indicator and Low Flow Alarm
The lter loading indicator (Fig. 12-5) monitors the pressure drop in the system. Increase loading of contaminants on the
lter is indicated by the progressive extinguishing of LEDs in the lter 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
airow the motor/blower will alarm. A low ow alarm is indicated by the bottom LED of the lter loading indicator ashing
RED. When the low ow alarm sounds, users must immediately exit the hazardous area and replace the
lter/cartridge and/or the prelter/spark arrestor in an area where intrinsically safe equipment is not required.
Step Down Feature
To conserve battery power when in the medium or high airow setting, the motor/blower will automatically step down to the
next lower airow setting when the lter loading reaches approximately 90% or the battery run time remaining is less than
4 hours. This can be over-ridden by the user by pressing the ow control button to move the airow back to the desired ow.
The low battery alarm and low ow alarm will always operate as described above, when either alarm sounds, users
must immediately exit the hazardous area and replace in an area where intrinsically safe equipment is not required.
