Component Description & Assembly - 3M Versaflo TR-800 Series User Instructions

5. Removal:
• Lift up on battery pack to remove from cradle.
• The 3M™ Battery Charger TR-640 can remain attached to the 3M™ 4-Station Battery Charger TR-944N if desired.
To release the cradle from base, press down on the oval release tab on the base, slide cradle forward and lift out. Be
careful not to pinch fingers as the cradle slides forward.
COMPONENT DESCRIPTION & ASSEMBLY
The 3M™ Versaflo™ Powered Air Purifying Respirator TR-800 System has multiple component options and optional
accessories. At a minimum, each NIOSH approved configuration of this PAPR system should include approved headgear
or facepiece, breathing tube, motor/blower, filter/cartridge, battery, and a belt or backpack. Common accessories include
prefilter/spark arrestor and filter cover. Refer to the supplied User Instructions for each of these components for additional
information prior to use.
High Efficiency (HE) Particulate Filter, Chemical Cartridge/Filter, Prefilter, Spark Arrestor and
Filter Covers
Always correctly use and maintain the filter/cartridge assembly. Failure to do so may reduce respirator performance,
overexpose you to contaminants, and may result in sickness or death.
a. Inspect filter/cartridge and inner circular sealing gasket before each installation. Replace filter/cartridge if damaged
or if the circular gasket is damaged or missing.
b. Always properly install the filter/cartridge into the blower unit.
c. Keep inner circular sealing gasket clean.
d. Never attempt to clean filters by knocking or blowing out accumulated material. Doing so will damage the filter media.
e. Use of the spark arrestor is mandatory for welding and all situations where the 3M™ Versaflo™ Powered Air
Purifying Respirator TR-800 may be exposed to sparks, molten metal or other hot particulates. Failure to use the
spark arrestor when needed may allow the filter to catch fire, or be damaged and allow contaminants to enter the
respirator and may result in sickness or death.
f. Store the filter as described in these User Instructions within the recommended storage temperature conditions
and observe filter expiration dates.
g. The filter loading indicator is for particulate loading levels only. It does not provide any information about gas and
vapor service life. Attempting to use the filter loading indicator for gases and vapors may result in sickness or death.
The 3M™ Versaflo™ Powered Air Purifying Respirator TR-800 can be used with either a high efficiency (HE) filter or
combination chemical cartridge/HE filter. The available filter and filter/cartridge options can be found at
www.3m.com/workersafety or in the TR-800 Components, Accessories and Replacement Parts guide.
Particulate Filter Loading
The 3M™ Versaflo™ Powered Air Purifying Respirator TR-800 Motor/Blower has a combination HE filter loading/low airflow
indicator (Fig. 12-5). This indicator is for particulate loading only; it does not apply to the service life of the carbon
in the chemical cartridge for the combination HE filter/gas and vapor cartridges. With a new HE only filter, all LEDs
on the indicator will light green. For certain combination HE filter/gas and vapor cartridges the inherent pressure drop, even
on a new cartridge/filter, may prevent the top LED on the filter loading indicator from being lit. As the HE filter becomes
loaded, the LEDs will begin to turn off. User must immediately leave the work area and the filter should be changed when the
audible alarm or a red LED activates or when the chemical cartridge service life is exceeded- whichever comes first. See the
"Operating Instructions" section of these User Instructions for further information on the HE filter/low airflow alarm.
Gas and Vapor Cartridge Service Life
The effective use time (service life) of a chemical cartridge (gas and vapor cartridge) will vary depending on your specific
environment. The user must determine a service life period based on their specific work conditions. The 3M™ Service Life
Software (www.3m.com/workersafety) may be able to assist user in this calculation.
Prefilter/Spark Arrestor
Use of the foam prefilter (3M™ Prefilter TR-6600) and metal mesh spark arrestor/prefilter (3M™ Spark Arrestor TR-662)
is optional in many situations. They can be used individually or in combination. Both act by helping to block larger particles
from reaching the main filter, and if changed (TR-6600) or cleaned (TR-662) frequently may help to extend the useable life of
the main filter. The spark arrestor may be cleaned by rinsing it under water. NOTE: Use of the spark arrestor is mandatory
for welding and all situations where the 3M™ Versaflo™ Powered Air Purifying Respirator TR-800 may be exposed
to sparks, molten metal or other hot particulates. Failure to use the spark arrestor when needed may allow the filter
to catch fire, or be damaged and allow contaminants to enter the respirator and may result in sickness or death. The
foam prefilter and the metal mesh spark arrestor must be used with a filter cover.
Filter Covers
Filter covers are available for each size of filter. Use of filter covers are highly recommended. Filter covers help protect the
filter body and filter media from damage from external forces. The filter cover must be in place if operating the PAPR in a
decon shower or while being subject to liquid spray. The filter cover helps the PAPR resist water spray directed towards the
wearer, such as if going through a decon shower. The filter cover is required when using a prefilter or spark arrestor prefilter.
