MSA SAFETY REGULATIONS
AirMaXX classic 5
1. Safety Regulations
1.1. Correct Use
The MSA AirMaXX®classic (hereinafter referred to as compressed air breathing
apparatus) is a self-contained breathing apparatus operating independently of the
ambient air for use in accordance to EN 137.
In combination with a certified facepiece (full face mask) the device protects the
wearer against inhalation of hazardous substances and mixtures, harmful
biological agents and oxygen deficiency.
Breathable air is supplied to the user from (a) compressed air cylinder(s) via a
pressure reducer, a lung governed demand valve (see Instruction Manual for the
Lung Governed Demand Valve) and a facepiece (see Instruction Manual for the
Facepiece). The exhalation air is released directly into the ambient atmosphere.
It is imperative that this operating manual be read and observed when using the
compressed air breathing apparatus. In particular, the safety instructions, as well
as the information for the use and operation of the apparatus, must be carefully
read and observed. Furthermore, the national regulations applicable in the user's
country must be taken into account for a safe use.
Alternative use, or use outside this specifications will be considered as non-
compliance. This also applies especially to unauthorised alterations to the
apparatus and to commissioning work that has not been carried out by MSA or
authorised persons.
Danger!
This product supports life and health. Inappropriate use, maintenance
or servicing may affect the function of the device and thereby seriously
compromise the user’s life.
Before use, the product operability must be verified. The product must
not be used if the function test is unsuccessful, it is damaged, a
competent servicing/maintenance has not been made, genuine MSA
spare parts have not been used.
Danger!
This compressed air breathing apparatus is a pure gas protection
device. It is not suitable for underwater diving.
1.2. Liability Information
MSA accepts no liability in cases where the product has been used
inappropriately or not as intended. The selection and use of the product are the
exclusive responsibility of the individual operator.
Product liability claims, warranties also as guarantees made by MSA with respect
to the product are voided, if it is not used, serviced or maintained in accordance
with the instructions in this manual.

2. Description
There are different models of as compressed air breathing apparatuses. All
combinations of the below mentioned versions (standard, -S, -Z, CLICK) are
possible.
All combinations can also be equipped with the Integrated Control Unit ICU or
ICU-S (version with key) instead of the pressure gauge.
Retrofitting is possible through MSA or authorized service centres.

MSA DESCRIPTION

2.1. Standard Model (AirMaXX classic)
The two-piece back plate of the compressed air breathing apparatus is adjustable
to three different lengths and should be adjusted to the user's height. The
pressure lines passes through the sliding upper part from the pressure reducer to
the pressure gauge and medium pressure coupling. They are fixed in special
receptacles and thus are always in the correct position.
The carrying belts and the hip belt are adjustable in length. The hip belt is fixed to
the back plate elastically. It will automatically return to the horizontal position on
installation.
One or two compressed air cylinders can be placed in the cylinder support. The
cylinder retaining strap is freely adjustable and after inserting the compressed air
cylinder(s), it is tightened and secured using the tension clamp.

Medium pressure line
The pressure reducer is mounted in the lower area of the back plate (Fig. 2).
On the pressure reducer, there is a relief valve, a warning device, the pressure
gauge line and the medium pressure line. The pressure reducer reduces the
cylinder pressure to approx. 7 bar and the relief valve activates on non-permitted
pressure rise to prevent damage insuring the continued supply of breathable air.
A water-tight encapsulated and shock-protected pressure gauge is connected to
the pressure reducer by the flexible pressure gauge line. The pressure gauge has
an easily readable, luminescent dial.
A lung governed demand valve or a full face mask is connected to the coupling
on the medium pressure line.
The acoustic warning device (signal whistle) triggers a continuous warning signal
when the cylinder pressure drops below 55 ±5 bar. It continues to sound
continuously, medium-pressure dosed until the usable air supply is nearly
exhausted. The warning device functions without an injector, meaning that no
ambient air is drawn in to produce the audible signal.
The breathing apparatus can be equipped with an Integrated Control Unit (ICU)

MSA

(Fig. 3). The ICU replaces the simple standard pressure gauge but incorpo-
rates a gauge in addition to the electronic features.
The ICU is used for the control and monitoring of the proper functioning of the
apparatus, the indication of operational data as well as indicating and signalling
hazardous conditions. It also warns when detecting motionlessness of the user
and offers the possibility of activating the alarm manually.
Please see for details the Instruction for Use of the ICU.

2.2. Model AirMaXX classic S
The compressed air breathing apparatus type AirMaXX classic S is equipped with
a signal line. The warning whistle is on a separate signal line near the ear of the
user where it can be heard well and easily identified as his own warning signal.

2.3. Model AirMaXX classic Z
The compressed air breathing apparatus type AirMaXX classic Z is equipped with
a second medium pressure connection. Thus is fitted on the left side of the
shoulder. It has a safety coupling which can be protected against dirt with a
stopper.
Attention!
When rescuing with the second connection the reduced service time
caused by the extra consumption of air by the person being rescued
must be considered.
Provided local regulations permit, the following are possible:
•To connect a second lung governed demand valve (emergency rescue of
another user of compressed air breathing apparatus).
•To connect a rescue set consisting of a lung governed demand valve and
full- face mask (Rescue Set Part No. D4075720).
•To connect to compressed air line system using the double nipple that is
available as accessory (Section 5), e.g. for decontamination after use.
According to the marking, connect the double nipple first with the short nipple side
to the second connection and then connect the long nipple side with the check
valve to the compressed air line.
