Entering And Exiting The Contaminated Area; Cleaning And Storage; Specifications - 3M Versaflo TR-300 Serie Manual De Instrucciones

in the motor/blower.
° If sparks or other hot particles are present, the TR-362 spark arrestor must be in place in front of the HE filter.
Failure to use the spark arrestor may allow the filter to be damaged with subsequent user exposure to
contaminated air.
5. Airflow check:
° Ensure ball in the TR-970 moves freely in its tube and the seal at the bottom end of the tube is in place. Rinsing
with clean water may help free a stuck ball. Allow tube and ball to dry prior to using.
° Insert the TR-970 air flow indicator into the outlet on the TR-300 motor/blower unit. If the breathing tube is in
place it must be removed to allow the air flow indictor to be inserted (Fig. 13a).
° Turn the motor/blower unit on by pushing and holding the power button. Run the TR-300 for 1 minute to allow
the air flow to stabilize.
° With the airflow indicator in a vertical position, ensure that the bottom of the floating ball rests at, or above, the
minimum flow mark (Fig. 13b). Airflow indicator must be in the vertical position for an accurate reading.
Fig. 13a Fig. 13b
NOTE: If the airflow indicator ball fails to rise at or above the minimum flow level, do not use the unit. Refer to the
TR-300 trouble-shooting guidance document or contact 3M Technical Service.
6. Check the low airflow alarm by simulating a low airflow condition. With the motor/blower on:
° Remove the air flow indicator and tightly cover the outlet of the motor/blower with the palm of your hand. The
motor should automatically speed up, attempting to compensate for the low airflow condition.
° Continue to press your palm tightly against the end of the outlet, making a tight seal. After approximately 30 seconds,
the unit will sound an audible alarm and the red fan shape LED on the top of the motor/blower unit will flash (Fig 12-3).
° Remove your hand from the end of the breathing tube; the audible alarm and the flashing red LED should both
stop when the motor returns to a slower speed.

ENTERING AND EXITING THE CONTAMINATED AREA

Prior to entering the contaminated area, complete the inspection procedures listed in these User Instructions.
1. Turn the motor/blower on.
2. Check airflow and alarms. NOTE: High environmental noise levels or use of hearing protection may interfere with
the user hearing the audible alarms. User may need to check for the visual alarms more frequently in high noise
environments.
3. Don the TR-300 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 only an audible or only a visual alarm triggers, the user
should still 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 specific exiting and decontamination procedures for turning off the motor/blower and removing the
respirator system.

CLEANING AND STORAGE

Dispose of lithium ion battery packs according to local environmental regulations. Do not crush, disassemble,
dispose of in standard waste bins, in a fire or send for incineration. Failure to properly dispose of battery packs
may lead to environmental contamination, fire or explosion.
The TR-300 assembly should be cleaned and inspected after each use and prior to storage.
Cleaning
Detach the battery pack, breathing tube and headgear from the motor/blower. 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 3M TR-300 PAPR assembly and battery pack with a soft cloth
dampened in a solution of water and mild, pH neutral detergent. 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. Ensure the electrical contacts of the motor/blower and battery pack are dry.
2. Breathing tube: Clean the connection sites on the breathing tube with the water and detergent solution. The
breathing tube can be immersed in water for cleaning. 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. Optional breathing tube covers can also be used to facilitate cleaning.
3. HE filter: Open the filter cover and inspect the HE filter (and prefilter or spark arrestor if used). Replace if
excessively dirty, wet or damaged. The HE and TR-3600 prefilter cannot be cleaned and must be properly
disposed of according to local regulations. The TR-362 spark arrestor/prefilter can be cleaned using the water
and detergent solution. Completely dry the spark arrestor with a clean cloth. If the spark arrestor cannot be
cleaned, or is damaged, replace with a new spark arrestor.
Motor Blower Storage
If motor blower will not be used on a regular basis, the motor must be run for 5 minutes annually to ensure proper
lubrication and operation.
Battery Pack Maintenance and Storage
The TR-330 and TR-332 must only be used with the TR-300 PAPR assembly and must only be charged on the
TR-341N or TR-344N charging stations. Refer to the TR-300 Chargers and Battery Packs User Instructions for specific
maintenance and storage recommendations. For long-term storage, the battery pack should be removed from the
motor/blower.
Do not store battery packs where temperatures may exceed 122°F (50°C).
