INTRODUCTION
12. Do not use ompressed oxygen with the PremAire
System.
13. Unless equipped with a pressure-demand fa epie e
and the Es ape-Cylinder option, the PremAire
Respirator MUST NOT be used and relied upon for
respiratory prote tion when the atmosphere ontains
on entrations of ontaminants whi h are unknown or
IDLH. Also, only the PremAire XV and the PremAire
Cadet XV with es ape ylinders are approved as an
entry and es ape respirator from IDLH atmospheres.
14. Users must wear suitable prote tive lothing and pre-
autions must be taken so that the respirator is not
worn in atmospheres that may be harmful to the
devi e.
15. Never alter or modify this devi e, ex ept as dire ted
by MSA during installation of NIOSH approved kits.
Use only MSA repla ement parts. If other than the
proper MSA parts are used, the NIOSH approval will
be voided.
16. Use only the listed hose lengths and air-pressure
range spe ified in these instru tions.
17. This approval applies only when the respirator is sup-
plied with respirable air through 8 to 300 feet of air-
supply hose within the pressure range of 60 to 100 psi
using Ultra Elite®and Ultravue®Fa epie es. When
using an Advantage 4000 Fa epie e ensure the pres-
sure range is between 70 to 100 psi. A maximum of
12 se tions of air-supply hose may be used in making
up the maximum working length of hose. Ea h se tion
of oiled hose is onsidered 50 feet in length (max. 6
se tions).
Particles and contaminants can enter an airline respi-
rator system when air-supply hoses are disconnected
and/or reconnected in a contaminated atmosphere.
This could result in serious injury or death depending
on the toxicity of the contaminant involved. It is the
responsibility of the user to determine the potential
risk and to take the necessary precautions which may
include a requirement that NO disconnection or recon-
nection of air-supply hoses be permitted in a contami-
nated atmosphere. If in doubt DO NOT disconnect
and/or reconnect. Failure to follow this warning can
result in serious personal injury or death.
18. When using Ultra Elite or Ultravue Fa epie es at tem-
peratures below 32˚F, nose up is required. A nose up
must always be used with the Advantage 4000
Fa epie e.

OPERATING PRINCIPLES
OPERATING PRINCIPLES
The PremAire System Supplied-Air Respirator provides
respirable air to the user on demand — not onstantly, as
in a onstant-flow type devi e.
The PremAire Respirator is a pressure-demand regulator
mounted at the fa epie e. This mask mounted regulator
(MMR) maintains a slight positive pressure within the fa e-
pie e while regulating and redu ing the air supply to a
breathable pressure. This is a omplished by using a pilot
diaphragm that senses the breathing demands of the user
in a ontrolled feedba k state.
The PremAire Respirator is designed to maintain a slight
positive pressure of air inside the fa epie e, whether the
wearer is inhaling or exhaling, to prevent ontaminants
from entering the fa epie e, should there be slight fa e-
to-fa epie e seal leakage.
As su h, it is suitable for use with a large, ompressed air
ylinder of breathable air or a bank of ylinders set up in
as ade fashion. Alternatively, the PremAire Respirator
an be used with a ompressor system designed and
onfigured to supply respirable breathing air to the respi-
rator, within the NIOSH approved pressure range.
In normal use, the pressure-demand respirator is onne t-
ed to an air supply of a type and duration sele ted by the
user and will provide respiratory prote tion as long as the
user remains onne ted to the air supply.
DO NOT use the PremAire Respirator in an IDLH
atmosphere UNLESS equipped with the emergency
escape air cylinder and a pressure-demand only face-
piece. This is because if the air supply should fail, the
user has no adequate means to escape from an IDLH
atmosphere to fresh air. Duo-Twin versions of the
PremAire System are not NIOSH approved for use in
IDLH atmospheres. Failure to follow this warning can
result in serious personal injury or death.
IDLH means onditions that pose an immediate threat to
life or health or onditions that pose an immediate threat
of severe exposure to ontaminants, su h as radioa tive
materials, whi h are likely to have adverse umulative or
delayed effe ts on health [Title 42 CFR, Part 84].
Non-IDLH means any hazardous atmosphere whi h may
produ e physi al dis omfort immediately, hroni poison-
ing after repeated exposure, or a ute adverse physiologi-
al symptoms after prolonged exposure. [Title 42 CFR
Part 84].
GENERAL INSTRUCTIONS
AIR SOURCE
The purity of the air supply is the responsibility of the user.
The respirator is approved only when the air supplied to
the respirator meets the requirements of the Compressed
Gas Asso iation Spe ifi ation G7.1 for Quality Verifi ation
Level (Grade) D Breathable Air. This requires that the air
ontain no more than 10 parts per million (ppm) arbon
monoxide, not more than 1000 parts per million (ppm)
arbon dioxide, and not more than 5 milligrams per ubi
meter of oil vapor or oil parti ulates.
AIR-SUPPLY HOSE AND PRESSURE GAUGE
The PremAire System an be used with a wide range of
MSA air-supply hoses, whi h an be inter onne ted up to
a maximum length of 300 feet. A maximum of 12 se tions
of air-supply hose may be used in making up the maximum
300 feet working length of hose. Ea h se tion of oiled
hose is onsidered 50 feet in length (maximum 6 se tions).
MSA air-supply hoses have various temperature limita-
tions. DO NOT use the PremAire System whenever ambi-
ent or inlet-air temperatures exceed the limits specified
below for each hose material. Failure to follow this warn-
ing can result in serious personal injury or death.
INLET PRESSURE GAUGE
To ensure a urate readings, the inlet pressure-gauge
assembly must be installed at the air sour e.
INTERCONNECTING AIR-SUPPLY HOSES
MSA air-supply hoses an be inter onne ted up to a
maximum length of 300 feet without voiding the NIOSH
approval. MSA offers both threaded and lo king-type
qui k dis onne ts.

before use. Che k the fa epie e, regulator, hoses and
all fittings for shipping damage. Repla e any damaged
omponents.
2. BEFORE EACH USE, inspe t the fa epie e, regulator,
and hoses for wear. Repla e any damaged ompo-
nents. See inspe tion guidelines.
DONNING THE APPARATUS
1. Remove the fa epie e from the ase.
Do not use a cover lens in a high-temperature environ-
ment, such as firefighting. High temperatures may dis-
tort the cover lens. Or, moisture trapped between a
cover lens and the facepiece lens may condense and
distort vision. Always remove the cover lens before
donning the facepiece. Failure to follow this warning
can result in serious personal injury or death.

ne t seal ring is seated properly in its groove, and that it
is not torn, gouged, or ni ked.
DONNING THE FACEPIECE
Do not wear eyeglasses under the facepiece. The tem-
ples or sidebars on eye glasses will prevent an airtight
seal. if you must wear glasses, install the spectacle
kit. Failure to follow this warning can cause inhalation
of contaminated air, resulting in serious respiratory
injury or death.
1. Extend the fa epie e

RESPIRATOR FIT TEST
A qualitative or quantitative fit test must be ondu ted for
ea h wearer of the respirator to determine the amount of
prote tion it will provide. Respirator fit tests are explained
fully in the Ameri an National Standard for Respiratory
Prote tion, ANSI Z88.2, whi h is published by the
Ameri an National Standards Institute.
Quantitative Test
If a quantitative fit test is used, a fit fa tor that is at least
1,000 shall be obtained before that respirator is assigned
to an individual.
Qualitative Test
If a qualitative fit test is used, only validated proto ols are
a eptable. The individual must pass a test designed to
assess a fit fa tor of at least 1,000.
Respirators must be qualitatively or quantitatively fit test-
ed in a negative-pressure mode.
The user must perform a respirator fit test and follow
all warnings and limitations specified. Failure to follow
this warning can result in serious personal injury or
death.
Respirator fit tests are explained fully in the Ameri an
National Standard “Pra ti es for Respiratory Prote tion,”
ANSI Z88.2 1980, published by the Ameri an National
Standards Institute.
Note: The user assumes all risks of death or serious bodi-
ly injury whi h an result if a fit test is not performed or
the respirator limitations are not followed.
FACEPIECE FIT CHECK
1. To he k the inhalation valve, inhale. If you do not
re eive suffi ient flow of air, remove and repla e the
fa epie e.
2. To he k for fa epie e fit, hold the palm of your hand
over the inlet onne tion and inhale. Hold your breath
at least 10 se onds. The fa epie e should ollapse
and stay ollapsed against your fa e. If it does not,
readjust the fa epie e and test again. If this does not
correct the leak, do not use the facepiece.
3. Test the exhalation
valve, take a deep
breath and hold it.
Blo k the inlet onne -
tion with the palm of
your hand and exhale.
If the exhalation valve
is stu k, you may feel a
heavy rush of air
around the fa epie e.
Note: You may need to exhale sharply to open the valve.
If this does not release the valve, do not use the fa e-
pie e. See PremAire Duo-Twin Instru tion Manual for Air
Tightness Test for Duo-Twin fa epie e (P/N 818370).
DONNING AND USING THE RESPIRATOR
Before donning and using the respirator, you must test
the apparatus for any leaks in the supplied-air system.
The respirator must be pressurized to conduct these
tests. See Instruction manual for the required leak test
procedures. Failure to follow this warning can result in
serious personal injury or death.
See PremAire Vortex Tube Instru tion Manual for
additional donning instru tions (P/N 497231).
This device may not seal properly with your face if you
have a beard, gross sideburns, or similar physical
characteristics (see ANSI Z .2). An improper facial
seal may allow contaminants to leak into the face-
piece, reducing or eliminating respiratory protection.
Do not use this device if such conditions exist. The
face-to-facepiece seal must be tested before each
use. Never remove the facepiece except in a safe,
non-hazardous, non-toxic atmosphere. Failure to fol-
low this warning can result in serious personal injury
or death.

CLEANING AND DISINFECTING
CLEANING AND DISINFECTING
Respirators should be leaned and disinfe ted after ea h
use. The fa epie e should be leaned and disinfe ted
after every use. Remove the filter artridges (if used). MSA
re ommends using Confiden e Plus®Cleaning Solution
(P/N 10009971). Refer to the label for user instru tions.
ANSI suggests that users be trained in leaning pro e-
dure.
• Cleaning and disinfecting at or below 110˚F tem-
perature will avoid possible overheating and dis-
tortion of parts which would require replacement.
• DO NOT use any cleaning substances that can or
might attach any part of the apparatus.
• DO NOT use alcohol because it may deteriorate
rubber parts.
• If not rinsed thoroughly, cleaning agent residue
may irritate the wearer’s skin.

INSPECTION
INSPECTION
DO NOT inspect the respirator before cleaning if there
is danger of contacting hazardous contaminants.
Clean and disinfect first, then inspect. Failure to follow
this warning can result in inhalation or skin absorption
of the contaminant and cause serious personal injury
or death.
Inspe t the respirator by sight and sound for normal oper-
ations after it has been leaned and disinfe ted. When
any part shows eviden e of damage, wear, or any other
adverse ondition explained in this se tion, it must be
repla ed and the ondition orre ted before the respirator
an be used again.
Note: Repla ement or repairs shall be done only by quali-
fied persons, using only MSA parts designed for the respi-
rator. No attempt shall be made to make adjustments or
repairs beyond the manufa turer's re ommendations.
Parts shall not be inter hanged among devi es of different
manufa turers. MSA authorizes levels of maintenan e and
repair for the PremAire System. (See new maintenan e
manual P/N 10017251.)
If there is no MSA Servi e Center in your area, return the
unit to MSA for servi e. Call 1-800-MSA-2222 for instru -
tions.
See PremAire Duo-Twin Instru tion Manual for other
general repair requirements.
Inspe t the entire apparatus after it is leaned and disin-
fe ted. ANSI Standards Z88.2 and Z88.5, des ribe three
levels of inspe tion pro edures whi h are to be per-
formed. Refer to these do uments or to an inspe tion
program prepared by a health professional in establishing
an inspe tion program. Detailed repair pro edures are
lo ated in PremAire User’s Maintenan e Instru tions.
If any of the following inspections do not function
properly, the apparatus must be removed from ser-
vice. Failure to follow this warning can result in seri-
ous personal injury or death.
Component Inspection
(After Each Use and Monthly)
1. Don the respirator following the instru tion pro e-
dures. These steps make up the Fun tional Test.
2. If all steps are performed su essfully, remove the res-
pirator and inspe t it following the steps below.
3. Fa epie e
a. Inspe t the fa epie e for rubber deterioration, dirt,
ra ks, tears, holes, or ta kiness.
b. Che k the harness headstraps for breaks, loss of
elasti ity, or missing bu kles and straps. Che k the
strap serrations for signs of wear.
. Inspe t the lens for ra ks, s rat hes, and a tight
seal with the fa epie e rubber.
d. The exhalation valve must be lean and operate
easily. The valve must move off the seat and return
when released.
e. Inspe t the fa epie e oupling for damage. Also
he k to be sure the spider gasket, O-ring, and
valve dis are present.
4. Harness
a. Inspe t all harness omponents for uts, tears,
abrasions, or signs of heat or hemi al-related
damage. Che k that the tee nuts, washers, and
s rews, if any, are se ure.
5. Re ord Keeping
a. Following inspe tion, the date and initials of the
designated person should be re orded on an
inspe tion tag. A more detailed re ord of the opera-
tions performed an be noted on an inspe tion and
maintenan e log. Inspe tion tags and inspe tion
and maintenan e logs are available from MSA.
When the inspe tion data has been re orded, the
apparatus is stored in a ready position.
Note: There are additional omponents to be inspe tion
for PremAire Cadet Respirators with Es ape Cylinder.
Refer to the Inspe tion se tion in P/N 497230.

TAL 801 (L) Rev. 8 - 496958
PREPARATION FOR STORAGE
Note: Do not for e-dry the parts by pla ing them in a
heater or in dire t sunlight. The rubber will deteriorate.
When the fa epie e is thoroughly dry, store the fa epie e
in the plasti bag that it was shipped in.
1. In general, only the fa epie e requires leaning and
disinfe ting after ea h use. If the apparatus is soiled
or has dirt a umulation, use a damp sponge with
mild soap solution or use a soft/medium bristle brush
to remove deposits that may interfere with normal
operation.
a. Ensure se ond stage regulator is free of water, dirt
or debris.
2. Inspe t the entire apparatus as you reassemble it.
Follow the Inspe tion Instru tions.
3. Thoroughly dry the fa epie e and regulator after
leaning and disinfe ting. The fa epie e an trap
water, whi h ould enter the regulator.
STORAGE
DO NOT store the respirator near substances that can
attack respirator components, causing them to fail to
perform as designed.
The PremAire CADET Respirator must be stored in a ool,
dry pla e away from dire t sunlight. Heat and sunlight will
shorten the life of rubber parts.

FUNCTIONAL CHECKS
FUNCTIONAL CHECKS
(After Each Use and Monthly)
1. Che k that the regulator works properly.
a. Che k that the ylinder valve and se ond stage
shut-off are losed and the system is not pressur-
ized.
b. Hold the fa epie e against your fa e to reate an
effe tive seal.
. Atta h the regulator to the fa epie e and inhale
until the fa epie e begins to ollapse against your
fa e. Hold your breath for about 10 se onds. The
negative pressure should be maintained and the
fa epie e should remain ollapsed against your
fa e for the entire 10 se onds.
d. Do not use the apparatus if negative pressure an-
not be maintained in the fa epie e. Return the regu-
lator and fa epie e to a ertified repairperson.
2. Inspe t the Se ond Stage Shut-Off.
a. With the regulator pressurized, operate ea h valve
to be sure it operates. Venting of pressure relief
valves (or a ontinuing flow of air through the regu-
lator when the user is not inhaling) indi ates that the
regulator needs to be repaired.
b. Listen to the regulator. Any unusual sounds, su h as
whistling, hattering, li king, or rattling mean that
the regulator should be he ked further.
. If any of these symptoms o ur, the apparatus must
be removed from servi e. Return the regulator to a
ertified repairperson.
DO NOT disconnect when pressurized. Release all
pressure from the regulator by opening the bypass
valve. Removing the regulator when pressurized can
result in serious personal injury, death, or damage to
equipment.
