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-300+ 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-300+ assembly and battery pack (still attached) with a soft cloth dampened
in a solution of water and mild, pH neutral, detergent. To minimize material falling into the motor/blower, remove
the filter (Fig. 7) and breathing tube (Fig. 9) while it is facing downward. Do not immerse the motor/blower
or battery pack in water. 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. Ensure the electrical contacts of the motor/blower and battery
pack are dry prior to using or charging.
2. Battery:
• While still on the blower, wipe the housing of the battery pack with a soft cloth dipped in mild cleaning solution.
Then wipe with a soft cloth dipped in clean water. Wipe dry.
• Remove battery and wipe down top of battery pack, if needed, with a soft dry cloth. Avoid contact with the
blower/charger connection pads; if they become damp, allow to dry before reinstalling on blower or charger.
3. Breathing tube:
• Detach breathing tube with unit upside down (Fig. 9).
• Clean the connection sites on the breathing tube with the water and detergent solution. The breathing tube can be
immersed in water for cleaning if required. The inside of the tube must be completely dried prior to use or storage.
• Air dry, or dry by connecting to the motor/blower unit and use it to force air through the tube until dry. Orient
tube to prevent water from running into blower.
• Optional plastic breathing tube covers (BT-922) may also be used to facilitate cleaning.
4. Belt:
• Remove the belt from the motor/blower by sliding it through the retaining slots on the back of the motor/blower
(if sliders are used, they may need to be removed as well). The 3M™ Easy Clean Belt TR-327 is made of a non-
porous material and can be wiped down or submersed in a soapy water solution. The 3M™ High Durability Belt
TR-326 is made of leather and can be cleaned with a leather cleaner.
• Wipe or rinse all belts thoroughly and dry completely before next use.
5. Filter:
• Remove the filter cover and inspect the filter (and prefilter/spark arrestor if used). Replace filter if excessively
dirty, wet or damaged.
• Do not attempt to clean the inside of the filter housing or the filter media itself. Do not clean with compressed or
pressurized air. Doing so will damage the media. The exterior of the filter can be gently wiped down with a dry
or damp cloth to remove excess dirt and debris.
• The prefilter (3M™ Prefilter TR-3600) cannot be cleaned. Replace if excessively dirty or damaged.
• The spark arrestor (3M™ Spark Arrestor TR-362) can be cleaned using a water and detergent solution.
Completely dry the spark arrestor with a clean cloth or air dry. If the spark arrestor cannot be cleaned or is
damaged, replace with a new spark arrestor.
NOTE: To minimize material falling onto the motor/blower, remove the filter while it is facing downward (Fig. 7).
Storage
Clean the system prior to storing. Store in a clean/dry environment not exposed to contaminant dusts, gasses or
vapors. Filters/cartridges may be stored attached to the blower. Do not hang blower or headtop by the breathing tube,
or hang the blower from the headtop. The system must be fully inspected prior to next use. For prolonged storage, the
motor must be run for 5 minutes annually to ensure proper lubrication and operation.
See "Specifications" section of these User Instructions for information on suggested storage temperatures.

Battery Pack Maintenance and Storage

Battery packs should be charged prior to storage. Battery pack charge depletes slowly during storage; battery packs
must not be allowed to fully discharge during extended storage. For short-term storage, the battery pack may be left
attached to the motor/blower. For long-term storage, the battery pack should be removed from the motor/blower. Refer
to the chargers and battery packs for the 3M™ Versaflo™ Powered Air Purifying Respirator TR-300 and TR-300+
Assemblies User Instructions for specific maintenance and storage recommendations.
