Service Life of Chemical Cartridges and Filters
3M™ 6000 Series Chemical Cartridges should be used before the expiration date on cartridge packaging.
The useful service life of these cartridges will depend upon activity of wearer (breathing rate); specific type,
volatility and concentration of contaminants; and environmental conditions such as humidity, pressure,
and temperature. Cartridges must be replaced in accordance with an established change schedule or
earlier if smell, taste or irritation from contaminants is detected.
Filters must be replaced if they become damaged, soiled or if an increase in breathing resistance occurs.
N-series filters should not be used in environments containing oils. R-series filters may be limited to 8
hours of continuous or intermittent use if oil aerosols are present. In environments containing only oil
aerosols, P-series filters should be replaced after 40 hours of use or 30 days, whichever is first.
ASSEMBLY INSTRUCTIONS
The 3M
TM
7800S can be used in many different configurations. It can be used as a positive or negative
pressure air-purifying respirator or in systems that are air supplied. The following assembly instructions
include negative pressure air-purifying, air supplied or combinations of both air supplied and air-
purifying. Separate assembly instructions are required for assembly in powered air-purifying systems
(PAPR) and supplied air systems.
3M™ Air-Purifying Assembly
The facepiece is pre-assembled with 3M
TM
Cartridge/Filter Adapters 701. When the cartridge/filter adapter
701 is used, the bayonet style filters/cartridges can be attached directly to the facepiece. If round retainer
style filter/cartridges are used, the cartridge/filter adapter 701 needs to be replaced with cartridge holders
7891.

3M™ 6000 Series Cartridges
3M™ 6000 Series Cartridges can be attached directly to the 3M™ Cartridge/Filter Adapters 701. Align the
cartridge notch with the small solid bayonet lug and push together. Turn the cartridge clockwise to stop
(1/4 turn). Repeat with second cartridge. Loosen the adapter nuts and position cartridge to desired
location. Note: If 3M™ Mercury Vapor Cartridges 6009 or 60929 are being used, position the cartridge at
the location that allows the greatest visibility of the ESLI. If the wearer cannot see the ESLI, do not use for
Mercury Vapor exposures. Hold cartridge in place and tighten nuts. (Fig. 2 and 3)
