• Remove your hand from the end of the breathing tube. In less than approx. 30 seconds, the
audible alarm and the flashing red LED should both stop when the motor returns to the selected
speed.
NOTE: If the low airflow alarm fails to sound, do not use the unit. Contact 3M Technical Service.
ENTERING AND EXITING THE CONTAMINATED AREA
Prior to entering the contaminated area, complete the Inspection procedures listed in these User
Instructions and ensure the selected PAPR setup is appropriate protection for the given airborne
contaminant and concentration.
1. Turn the motor/blower on.
2. It is recommended to check both the airflow with the airflow indicator and low flow alarms. NOTE:
High environmental noise levels or use of hearing protection may interfere with the user's ability to
hear audible alarms. Heavy clothing or tasks with high vibration levels may interfere with sensing the
vibratory alarm. User may need to check for the visual alarms more frequently in high noise, or high
vibration environments.
3. Don the 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 Assembly and Headgear. Enter
the work area.
4. Leave the contaminated area immediately if any of the following conditions occur:
a. Any part of the system becomes damaged.
b. Airflow into the respirator decreases or stops.
c. The low airflow or low battery alarms trigger. In the event an audible, visual, or vibratory alarm
triggers, the user should immediately leave the contaminated area.
d. Breathing becomes difficult.
e. You feel dizzy or your vision is impaired.
f. You taste or smell contaminants.
g. Your face, eyes, nose or mouth become(s) irritated.
h. You suspect that the concentration of contaminants may have reached levels at which this
respirator may no longer provide adequate protection.
5. Do not turn off the motor/blower, remove the facepiece or headtop, or reach your hand into
the headgear in areas where the air is contaminated. This could allow contaminants to enter the
respirator and may result in sickness or death.
6. Follow your facility's specific exiting and decontamination procedures for turning off the motor/
blower and removing the respirator system.
CLEANING, STORAGE AND DISPOSAL
The 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 Assembly should be cleaned and
inspected after each use and prior to storage. Refer to 3M Technical Data Bulletin #222 Cleaning and
Maintenance of TR-600 for additional guidance.
Cleaning
While system is together and still running, conduct a general wipe down/removal of dust and
debris with a soft brush or soft cloth prior to disassembly. Remainder of cleaning steps should be
conducted outside of the hazardous area with the blower turned off. Inspect all parts for damage or
other signs of excessive wear. Replace all damaged parts prior to storage or next use.
1. Motor/blower:
• Clean the outer surfaces of the TR-600 assembly and battery pack (still attached) with a soft
cloth dampened in a solution of water and mild, pH neutral detergent. Do not use solvents or
abrasive cleaners. Do not attempt to clean the interior of the motor/blower with compressed air
or vacuum. Do not attempt to clean the battery connection pins on the blower or the blower/
charger connection pads on the battery - these are coated and direct cleaning with moist
cloths or wipes should be avoided.
• If additional cleaning is required, remove the filter/cartridge and breathing tube. To minimize
material falling onto the motor/blower, remove the breathing tube (Fig. 12) and filter/cartridge
(Fig. 6) while it is facing downward. Remove the battery. Attach the air inlet and air outlet
cleaning and storage plugs (3M™ Cleaning and Storage Kit TR-653) into the TR-600 (Fig. 16).
The TR-600 can now be rinsed under running water, immersed, or put in a respirator washer for
further cleaning. Water temperature should not exceed 122°F (50°C). The plug gaskets should be
inspected for damage and wear prior to each use. Worn or damaged gaskets must be replaced.
Washing the TR-600 while using damaged plug gaskets may cause damage to the TR-600 and
void the warranty. Blowers which have been dropped or damaged should not be immersed or put
into a respirator washer due to potential water ingress. NOTE: Gaskets should be replaced every
30 uses or yearly, whichever comes first, to minimize use of worn gaskets.
