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 ngers as the cradle slides forward.
COMPONENT DESCRIPTION & ASSEMBLY
The 3M™ Versao™ Powered Air Purifying Respirator TR-800 System has multiple component options and optional
accessories. At a minimum, each NIOSH approved conguration of this PAPR system should include approved headgear
or facepiece, breathing tube, motor/blower, lter/cartridge, battery, and a belt or backpack. Common accessories include
prelter/spark arrestor and lter cover. Refer to the supplied User Instructions for each of these components for additional
information prior to use.
High Efciency (HE) Particulate Filter, Chemical Cartridge/Filter, Prelter, Spark Arrestor and
Filter Covers
W WARNING
Always correctly use and maintain the lter/cartridge assembly. Failure to do so may reduce respirator performance,
overexpose you to contaminants, and may result in sickness or death.
a. Inspect lter/cartridge and inner circular sealing gasket before each installation. Replace lter/cartridge if damaged
or if the circular gasket is damaged or missing.
b. Always properly install the lter/cartridge into the blower unit.
c. Keep inner circular sealing gasket clean.
d. Never attempt to clean lters by knocking or blowing out accumulated material. Doing so will damage the lter media.
e. Use of the spark arrestor is mandatory for welding and all situations where the 3M™ Versao™ 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 lter to catch re, or be damaged and allow contaminants to enter the
respirator and may result in sickness or death.
f. Store the lter as described in these User Instructions within the recommended storage temperature conditions
and observe lter expiration dates.
g. The lter loading indicator is for particulate loading levels only. It does not provide any information about gas and
vapor service life. Attempting to use the lter loading indicator for gases and vapors may result in sickness or death.
The 3M™ Versao™ Powered Air Purifying Respirator TR-800 can be used with either a high efciency (HE) lter or
combination chemical cartridge/HE lter. The available lter and lter/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™ Versao™ Powered Air Purifying Respirator TR-800 Motor/Blower has a combination HE lter loading/low airow
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 lter/gas and vapor cartridges. With a new HE only lter, all LEDs
on the indicator will light green. For certain combination HE lter/gas and vapor cartridges the inherent pressure drop, even
on a new cartridge/lter, may prevent the top LED on the lter loading indicator from being lit. As the HE lter becomes
loaded, the LEDs will begin to turn off. User must immediately leave the work area and the lter should be changed when the
audible alarm or a red LED activates or when the chemical cartridge service life is exceeded- whichever comes rst. See the
“Operating Instructions” section of these User Instructions for further information on the HE lter/low airow 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 specic
environment. The user must determine a service life period based on their specic work conditions. The 3M™ Service Life
Software (www.3m.com/workersafety) may be able to assist user in this calculation.
Prelter/Spark Arrestor
Use of the foam prelter (3M™ Prelter TR-6600) and metal mesh spark arrestor/prelter (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 lter, and if changed (TR-6600) or cleaned (TR-662) frequently may help to extend the useable life of
the main lter. 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™ Versao™ 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 lter
to catch re, or be damaged and allow contaminants to enter the respirator and may result in sickness or death. The
foam prelter and the metal mesh spark arrestor must be used with a lter cover.
Filter Covers
Filter covers are available for each size of lter. Use of lter covers are highly recommended. Filter covers help protect the
lter body and lter media from damage from external forces. The lter cover must be in place if operating the PAPR in a
decon shower or while being subject to liquid spray. The lter cover helps the PAPR resist water spray directed towards the
wearer, such as if going through a decon shower. The lter cover is required when using a prelter or spark arrestor prelter.
