The service life of this respirator will vary depending on the
work environment.
4.1.1 CARTRIDGES
When you are using a gas or vapor cartridge respirator which
does not have End-Of-Service-Life Indicators, you
must establish a change out schedule that will result in car-
tridges being changed before the end of their useful life.
North provides EZ GUIDE
TM
software for assisting the user
in establishing a change out schedule.
If the respirator has End-Of-Service-Life Indicators, the
cartridges must be changed when the color of either one
of the indicators match the color standard indicated on the
cartridge.
4.1.2 PARTICULATE FILTERS
When you are using a particulate filter respirator, or a gas or
vapor respirator with filters attached, the filters should be
replaced when breathing becomes difficult.
Any “R” class filter if used in an oil environment must be
replaced after 8 hours of total use, or sooner, regardless of
breathing resistance.
5 TO TAKE OFF THE RESPIRATOR
1)
Go to an area with uncontaminated breathable air.
2)
Loosen head bands and remove the facepiece.
6 TURNAROUND MAINTENANCE
After each use, the respirator should be examined by trained
personnel.
6.1 AIR-PURIFYING ELEMENT REPLACEMENT
6.1.1 FILTERS
To replace pad style filters, detach the filter cover from the
cartridge or filter holder, discard the old filters and replace
them with new ones. Follow the directions printed on the
filter for proper orientation. Check to ensure that the entire
outer edge of the filters are seated evenly and securely
against the inner wall of the filter covers. Snap the filter
covers with the filters to the cartridges or filter holders. (See
Figures 1 and 2.)
6.1.2 CARTRIDGES
To replace gas, particulate or combination cartridges,
unscrew them from the inhalation connectors, which are
mounted on the facepiece, and discard them. Screw on new
air-purifying elements effectively to insure an effective seal
between each air-purifying element and the grommet on the
facepiece lens. (See Figure 3.)
6.2 INSPECTION
Visually inspect all components for damage or wear, espe-
cially rubber parts. Replace parts where needed.
If needed, clean and sanitize the facepiece assembly. (See
Section 8: Periodic Maintenance.
7 STORAGE
Store in a clean dry area in the respirator storage bag provid-
ed with the facepiece.
8 PERIODIC MAINTENANCE
As needed, remove, inspect and clean facepiece and breath-
ing tube assembly.

Always replace air-purifying elements after water spray
decontamination. Excessive moisture can damage the
air-purifying elements and expose the user to the risk
of serious injury, illness or death.
WARNING
It is good hygiene practice to replace the air-purifying ele-
ments after a single day of use even if the service life of
the air-purifying elements has not expired.
NOTE
The replacement of air-purifying elements must be done
in a safe area containing uncontaminated breathable air.
NOTE
Rubber and elastomeric parts
must
be stored in a
manner which will prevent them from taking an abnor-
mal set. Do
not
expose this device, during storage, to
excessive heat (above 140°F/60°C), moisture, contam-
inating gaseous substances or airborne particulates.
Excessive heat may distort the facepiece resulting in
the inability to achieve a proper fit. Moisture and con-
taminated air can damage the air purifying elements.
Either of these conditions will expose the wearer to
the risk of serious injury, illness or death.
CAUTION
The NIOSH Approval and all North warranties for this
respirator are nullified if other than North replacement
parts are used.
