shower. It is preferred the unit remain running during the decontamination shower, however, it can be turned off if required.
The motor/blower unit without a breathing tube attached cannot be taken through a decontamination shower as water may
enter the motor/blower unit through the air outlet. If the user removes their headgear, ensure the breathing tube remains
attached and allowed to dangle towards the floor to ensure water does not enter the breathing tube or the motor/blower unit.
After going through the shower ensure all outer surfaces are wiped off before dissembling the system. All system components
should be thoroughly dry before storage or next use.
Filters and Filter Accessories
The HE filter and foam prefilter (if used) cannot be cleaned. Attempts to clean the filters may damage them and in the case of
the HE filter allow particulates to enter the respirator and the user's breathing zone. Damaged filters or filters beyond their
service life should be replaced.
The metal spark arrestor/prefilter may be cleaned with a mild, pH neutral cleaner. Dry thoroughly before next use or storage.
If the spark arrestor/prefilter cannot be cleaned, it should be replaced.

Storage
Motor/Blower
Store in a clean, contaminant free environment, protected from prolonged exposure to heat, sunlight, radiation and chemicals.
For prolonged storage, the motor/blower should be run at least once per year for 5 minutes to ensure continued proper
lubrication of the motor.

IMPORTANT NOTE
Respirators used for emergency purposes must be inspected monthly per OSHA 29CFR1910.134. This should include
running the motor/blower.
Filters and Filter Accessories
HE filter, prefilter, and spark arrestor/prefilter should be stored at temperatures and conditions similar to the motor/blower.
Store the filter and spark arrestors in the original 3M packaging until ready for installation in the motor/blower. HE filters should
not be stored long-term on the motor/blower as this may damage the filter gasket. HE filters have a shelf life of 5 years when
stored in their original packaging.
Battery Pack
Refer to the TR-300+ Chargers and Battery Packs User Instructions and
PAPR Batteries
for additional information. Do not use, charge, or store battery packs where temperatures may exceed 122º F
(50º C). Battery packs can be stored on the charger between uses. For storage greater than 30 days, the battery pack should
be stored off charger with approximately 40% charge (as shown by the battery pack fuel gauge). Recharge before next use.
For infrequently used battery packs, to maximize pack life, store battery pack off charger at 40% charge. Approximately every
6 months, fully charge the battery packs and run down to approximately 40% charge before returning to storage.
