• Continue to press your palm tightly against the end of the outlet, making a tight seal. In less than approx. 30 seconds,
the unit will sound an audible alarm, and the bottom bar on the filter loading/low flow indicator will flash red.
(Fig. 12-5).
• 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. 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-800 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 remove the respirator or reach your hand into the headgear in areas where the air is contaminated.
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-800 Assembly should be cleaned and inspected after each use
and prior to storage.
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-800 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. 11) 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-800 (see Fig. 15). The TR-800 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-800
while using damaged plug gaskets may cause damage to the TR-800 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.
Gaskets should be replaced every 30 uses or yearly, whichever comes first, to minimize use of worn gaskets.
