Operating Instructions - 3M Versaflo TR-300+ Serie Mode D'emploi

Back Pack (optional)
The BPK-01 back pack may be used in place of the belt (Fig. 11a):
1. With either end of the motor/blower towards the top of the back pack (end with the loop handle), thread the
backpack strap through the top retaining slot on the motor/blower and the large retaining sleeve (Fig. 11b-1) on
the back pack.
2. Thread the strap through the lower retaining slot on the motor/blower and the small retaining sleeve (Fig. 11b-2)
on the back pack.
3. Thread the strap through the buckle (Fig. 11b-3) and tighten down.
4. Don the backpack and adjust the shoulder straps for a comfortable fit.

OPERATING INSTRUCTIONS

Power 3M™ Versaflo™ Powered Air Purifying Respirator TR-300+ on
Press the blue power/flow control button (Fig. 12 or 13-1) for 2 seconds and release. The unit will turn on and perform
a self-diagnostic. The flow level, filter loading and battery charge indictors will blink and the auditory alarm will sound.
Battery indicator (Fig. 13-3) will show current charge status of the battery pack. Filter indicator will show remaining
capacity of the filter (Fig. 13-4). 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 or visual indicators do not activate at start-up,
do not use system. Restart and if alarm conditions persist, remove from service and see your supervisor.
Select airflow
There are two user selectable airflow settings- standard and high flow. The motor/blower will start up at the standard
flow setting. Pressing the blue power/flow control button (Fig. 13-1) two quick times (< 1 second each) and releasing will
cycle the motor/blower to the next of the two flow settings. One green LED light on the flow setting indicator (Fig. 13-2)
indicates standard flow, two green LED lights on the flow setting indicator indicate high flow.
Power 3M™ Versaflo™ Powered Air Purifying Respirator TR-300+ off
Press and hold the blue power/flow control button for 2 seconds (Fig. 13-1).
Display Sleep Mode
To conserve battery power, the display will go into 'sleep mode' after 30 seconds from the last button press. The
flow speed indicator will periodically blink with the current flow setting (Fig. 13-2). To wake up the display, press and
release the power/flow control button.
Battery Charge Status Indicator and Low Battery Alarm
The battery level/alarm indicator (Fig. 13-3) 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. 13-4) monitors the pressure drop in the system. Increased 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 and/or the prefilter/spark arrestor.
