1. I TRODUCTIO
This device is one component of a North air-purifying respirator. The
attachment of a pair of suitable filters from the North 7500 series will
provide respiratory protection against hazardous vapours, gases
and/or particulate matter, depending on the filters used and the conta-
minant concentration and/or toxicity; provided there is sufficient oxy-
gen present in the contaminated atmosphere to support life.
A choice of three sizes of facepiece and a wide variety of filters are
available.
1.1 IMPORTA T I FORMATIO
This Operating and Maintenance Instruction Manual contains impor-
tant information and must be completely read and understood by all
persons who may use or maintain this respirator.
This Respirator should be used or maintained only by persons who
understand the instructions contained within this manual.
1.1.1 TERMI OLOGY
Warnings, cautions and notes used in this manual have the following
significance:

GB

1.1.2 GE ERAL WAR I GS
WAR I GS
1. Failure to properly select the appropriate respirator for all the
contaminants and their concentrations against which protec-
tion is required, or a failure to follow North’s instructions and
warnings, may result in exposure to the hazardous materials,
causing serious illness, disability or death of the affected
worker.
2. Do not use this respirator for protection against air contami-
nants other than those listed on the instructions which accom-
pany each filter. If in any doubt, contact your local distributor.
3. Do not use this respirator under any of the following conditions:
• While performing or observing abrasive blasting (sand-
blasting) operations.
• For fire fighting.
• For protection from fumigants.
• In oxygen-deficient atmospheres (any atmosphere having
less than 17% oxygen by volume at sea level).
• In atmospheres where the concentrations of toxic contami-
nants are unknown, or are IDLH. (An IDLH atmosphere is an
atmosphere which has a concentration of any toxic, corro-
sive or asphyxiant substance that poses an immediate threat
to life, which would cause irreversible debilitating effects on
health, or which would interfere with the ability to escape
from a dangerous atmosphere.)
• In atmospheres where the concentration of the contami-
nant exceeds the respirator’s Maximum Use Concentration
listed in the table below;
TYPE OF FILTER MAXIMU USE CO CE TRATIO
as or Vapour 10 X OEL or 1000 ppm Maximum
P1 4 X OEL
P2 10 X OEL
P3 20 X OEL
or;
4GB

WAR I GS
any lower Maximum Use Concentration for that contaminant
(when using a half mask air purifying respirator) established by
other National legislation or regulations.
• In poorly ventilated areas, or confined spaces such as tanks,
small rooms, tunnels or vessels, unless the confined space is
well ventilated and the concentration of toxic contaminants is
known to be, and will continue to be, below the Maximum
Use Concentration recommended for the respirator.
• For protection against gas or vapour contaminants with poor
warning properties (irritation, odour or taste) at or below their
permissible exposure standard or those which are sensory
desensitizers, unless the filter is equipped with an End-of-
Service-Life Indicator.
• For protection against gases or vapours which generate high
heats of reaction with the sorbent material in the filter.
4. Do not use any air purifying respirator when conditions pre-
vent a good facepiece-to-face seal. Examples of such condi-
tions are:
i. the growth of facial hair which will pass between the face-
piece sealing area and the face;
ii. the use of spectacles, goggles or other devices which
interfere with the respirator;
iii. the use of head or face coverings which contain materials
which will pass between the facepiece sealing area and
the face; and
iv. missing teeth or dentures, facial deformities or deep scars.
5. Any air purifying respirator, when properly selected and fitted,
will significantly reduce, but will not completely eliminate, the
breathing of contaminant(s) by the respirator wearer. When
working in atmospheres containing substances which are
reported to cause cancer, the wearer will obtain better protec-
tion from a continuous flow or positive pressure air supplied
respirator, or self-contained breathing apparatus (an SCBA).

GB

WAR I GS
1.1.3 USER REQUIREME TS
To use this respirator you must know;
1) The contaminants and their concentrations. (Ask your Safety
Managers or Occupational Hygienist.)
2) That this is the respirator approved for use against those contami-
nants and at those concentrations.
3) That the contaminated atmosphere is not Immediately Dangerous
to Life or Health (IDLH). For the definition of IDLH see Warning #3
of the preceding list of eneral Warnings.
4) That this respirator fits you properly. (See Warning #4 of the pre-
ceding list of eneral Warnings.)
5) That you do not have any physical limitations or illness which
would be aggravated by an increase in breathing resistance, or
would otherwise preclude you from using this respirator. (Ask your
Safety Manager or Doctor.)
You should not enter any potentially contaminated atmosphere
unless you have confirmed all of these factors.
1.1.4 TRAI I G PROGRAM
These brief written instructions cannot substitute for a formal
Respirator Training Program. Such training should include an opportu-
nity for you to handle the respirator, learn how to inspect it, have it
properly fitted, test its facepiece-to-face seal, wear it in normal air for
a long familiarity period, and finally, to wear it in a test atmosphere.
6. This respirator does not provide protection to exposed areas
of the body. If the contaminated atmosphere contains
vapours, gases or airborne particulate matter which may
either irritate or burn the eyes or the skin, or can be
adsorbed by the body through penetration of the skin, the
use of specialized eye, hand and/or body coverings may be
required for protection.

2. PRE-USE I STRUCTIO S
2.1 FACEPIECE
Remove the facepiece assembly from its container and visually check
the facepiece to make sure that the sealing flange is not distorted,
that all components including the exhalation valve flap are in place, in
good condition and secure.
2.2 PRE-FILTERS
If replaceable pre-filters are being used, the
pre-filters should be assembled to the filters
before they are attached to the facepiece.
Place one pre-filter in each N7500-27 fit
check/filter cover so that the entire outer edge
of the pre-filter is seated evenly and securely
against the inner wall of the filter cover (See
Figure 1).
Snap the fit check/filter cover, with the
pre-filter seated evenly and securely, to
the filter (See Figure 2).
2.3 ASSEMBLI G THE RESPIRATOR
WAR I G
The respirator facepiece and filters may be sold separately. Do
not use this respirator unless the proper filters are attached.
Check with your Safety Manager or Occupational Hygienist to
make sure you have the proper components. If in any doubt, con-
tact your local distributor.
7
FIGURE 1
Assembling the Pre-Filter
FIGURE 2
Attaching the Cover

Assemble the respirator by screwing the two
appropriate filters onto the inhalation con-
nectors mounted on the facepiece.
Check to be sure that each filter is
tightly sealed against the face-
piece (See Figure 3).
After assembling the respirator
facepiece and filters, inspect the res-
pirator to make certain that the respirator
has not been damaged.
CAUTIO
3. TO PUT O THE RESPIRATOR
The following should be performed in an
area with uncontaminated air.
1) Remove your eyewear (if worn), then
grasp the front of the respirator with
one hand and the upper headband with
the other hand. Then place the portion
of the facepiece containing the exhala-
tion valve under the chin (See Figure 4).
2) Position the narrow portion of the respi-
rator on the nose bridge and place the cradle
suspension system on the head so that the
top headband rests across the top of the
head and the bottom headband rests
above the ears, on the back of the
head. Then hook the bottom head-
band behind the neck, below the ears,
and adjust the position of the face-
piece on the face for best fit and
comfort (See Figure 5).
A respirator must be inspected by the wearer before and after each
use to ensure that it is in good working condition.

GB

3) The lengths of the headbands are adjustable;
tighten or loosen by holding the respirator body
or headband yoke with one hand and pulling
on the elastic material in the appropriate
direction with the other hand (See Figure 6).
OTE
4) Position the facepiece so that the nose section
rests as low on the bridge of the nose as is
comfortable, and tighten the upper headband
on both sides just tight enough so that the
respirator doesn’t slide down on the nose.
Do not over tighten. If the respirator pinches
the nose, loosen the upper headband
slightly (See Figure 7).
5) Then, tighten the lower headband on
both sides just tight enough to secure the
respirator under the chin (See Figure 8).
OTE
6) If you previously removed your eyewear,
put it back on at this time.
For a proper positioning and com-
fort, the upper headband must
be adjusted first, then the lower
headband must be adjusted.
For a comfortable fit, the head-
bands must be adjusted equally
on both sides of the respirator. FIGURE 6

3.1 TESTI G FOR FIT
This respirator is available in three sizes; large, medium and small.
Most faces can be fit with the medium, however people with small
faces may get a better fit with the small size, and people with large
faces may get a better fit with the large size.
3.1.1 I ITIAL FIT TESTI G
A respirator should not be assigned to a person unless the person is
given a fit test and the results of the test indicate that the facepiece of
the respirator fits properly.
Fit tests should be conducted at least annually and sooner if there are
factors such as weight change or dental surgery which may affect the
fit of the respirator.
3.1.2 PERIODIC FIT CHECKS
Each time that the respirator is put on, before entering an area con-
taining hazardous atmospheres; and then periodically while wearing
the respirator in the contaminated area, the respirator wearer should
check the tightness of the seal of the facepiece to the wearer’s face
by carrying out a negative or positive pressure fit check. Readjustment
of the position of the facepiece on the wearer’s face and/or the ten-
sion of the headbands should be made if necessary.
3.1.2.1 EGATIVE PRESSURE FIT CHECK
Place the palms of the hands over the openings in
the N7500-27 fit check/filter covers, inhale and
hold your breath for about 5 seconds. If the
facepiece collapses slightly and no air leaks
between the facepiece and the face are detect-
ed, a good fit has been obtained. If air leaks
are detected, reposition the facepiece on the
face and/or readjust the tension of the head-
bands and repeat the negative pressure
check until an effective seal is obtained (See
Figure 9). FIGURE 9
Negative Pressure
Fit Check
10 GB

3.1.2.2 POSITIVE PRESSURE FIT CHECK
Using the palm of a hand to close the openings
in the exhalation valve guard, simultaneously
exhale. If the facepiece bulges slightly and no
air leaks between the facepiece and the face
are detected, an effective fit has been
obtained. If air is detected to be leaking out
between the facepiece and the face, reposition
the facepiece on the face and/or readjust the
tension of the headbands to eliminate the leak-
age. This check must be repeated until an
effective seal of the facepiece to face is
obtained (See Figure 10).
4. USE
You are now ready to enter the use environment for which the respira-
tor is intended.
WAR I G
4.1 SERVICE LIFE
The service life of this respirator will vary depending on the work envi-
ronment.
4.1.1 GAS FILTERS
When you are using gas or vapour filters which do not have end-of-
service-life indicators, you will know the service life is ending when
Immediately leave the work area and replace the respirator if;
i. breathing becomes difficult;
ii. dizziness or other distress occurs,
iii. you smell, taste or sense irritation from the contaminants
in the work area, or
iv. the respirator becomes damaged.
Should any of these occur, you risk exposure to hazardous quan-
tities of the air contaminant which can result in serious injury or
death.
FIGURE 10

GB

you smell, taste, or sense irritation from the contaminants while wear-
ing the respirator.
If using an end-of-service-life indicator the filters must be changed
when the color of the indicator matches the color standard indicated
on the filter.
4.1.2 PARTICULATE FILTERS
When you are using a particulate filter or pre-filter with this respirator,
the filter or pre-filter should be replaced when breathing becomes dif-
ficult.
5. TO TAKE OFF THE RESPIRATOR
1) o to an area with uncontaminated air.
2) Loosen headbands and remove facepiece.
6. I SPECTIO
After each use, the respirator should be examined by trained person-
nel:
Visually inspect all components for damage or wear, especially rubber
parts. Replace parts where needed.
Clean and sanitize the facepiece assembly (See section 8: Periodic
Maintenance).
6.1 FILTER REPLACEME T
OTE
WAR I G
Always replace filters after water spray decontamination. Exces-
sive moisture can destroy certain filter’s ability to remove contami-
nants from the air and cause complete blockage of others.
It is good hygiene practice to replace the filters after a single day of
use even if the service life of the filter has not expired. This must be
done in an area containing uncontaminated breathable air
12 GB

6.1.1 PRE-FILTERS
To replace pre-filters, detach the fit check / filter cover from the filter
or filter holder, discard old pre-filters and replace them with new ones.
(See Figure 1 and 2.)
6.1.2 FILTERS
To replace gas, particulate or combination filters, unscrew them from
the inhalation connectors, which are mounted on the facepiece, and
discard them. Screw on new filters tightly to insure a tight seal
between each filter and the facepiece (See Figure 3).
7. STORAGE
Store in a clean dry area in the respirator storage bag provided with
the facepiece.
CAUTIO
8. PERIODIC MAI TE A CE
A respirator must be inspected and maintained and a record kept of
each such inspection and maintenance. If the respirator is utilised as
part of a disposable program and is replaced monthly or sooner, then
no records of maintenance are required.
As needed, clean facepiece assembly.
WAR I G
All North warranties for this respirator are nullified if other than
North replacement parts are used.
Rubber and elastomeric parts must be stored in a manner which
will prevent them from deformation. Do not expose this device,
during storage, to excessive heat (above 140ºF/60ºC), moisture,
contaminating gaseous substances or airborne particulates.
13
GB

8.1 CLEA I G A D DISI FECTI G
1) Remove filters from connectors and discard them.
2) Inspect headbands for wear. Check all elastomer and rubber parts
for pliability and signs of deterioration.
3) Remove the facepiece inhalation connectors, headband assembly,
exhalation valve guard, valve and seat from the facepiece.
4) Remove the inhalation valves from inhalation connectors.
5) Prepare a solution of cleaner/sanitizer (North part number 80992)
according to the cleaner/sanitizer instructions.
6) Wash facepiece and components in cleaning solution.
7) Rinse components completely in clean warm water, then air dry in
clean area.
8) Visually inspect the inhalation and exhalation valve for damage. If
damage or wear is evident, replace.
9) Reassemble the facepiece. Follow steps 1 through 4 above, in
reverse order.
OTE
8.2 PREPARE FOR USE
1) Install a new pair of filters.
2) Perform a fit check to make sure that components are functioning
properly.
The use of cleaning agents other than those mentioned above
may invalidate the product warranty.
