4. Preparation
4.1 Changing Connector Position
If the filter position needs to be changed, alignthe tool key
to the NATO plug, and turn the tool key counter clockwise to
unscrew the NATO plug” (figure 4.1_1). Remove the NATO plug
from the thread connector and screw it (turn clockwise) into
the other thread connector. Plug must be tightly screwed with
the use of the key tool by hand (figures 4.1_2 A to D). The plug
is marked “IM76 019006501.”
Important: Never connect more than one filter at a time! All
other thread connectors must be tightly plugged.
4.2 Disconnecting and connecting harness
The mask could be provided with two options, rubber/textile
harness interfaces. Changing between the options can be done
by the user, as shown.
Note: the upper straps can be adjusted only in the textile
harness.
Connecting and disconnecting harnesses for maintenance or
changing the harness (for comfort or disinfection) can be done
by the user, as shown.
Use a flat, narrow screwdriver between the buckle and the
buckle connector, (see figure 4.2_1) and carefully lever the
buckle connector (see figure 4.2_2 and 4.2_3). Repeat on all
other buckles, so that the harness can be removed.
To attach the new harness, align all 6 buckles to their
corresponding rubber straps on the mask (one at a time) and
click in the buckle connectors back to their positions.
Note: make sure to attach the new harness in the correct
orientation: - Rubber harness: the manufacturing date is
visible when worn. - Textile harness: the IMPERTECH logo
is seen when worn.
In any case, the ends of the harness straps must face outside
(figure 4.2_3).
4.3 Use of Accessories
4.3.1 Corrective eyewear
Frames for corrective glasses can be ordered empty, i.e. without
corrective lenses. The frame comes with an adapter to fit into
the IM76. Whenever eyewear is needed, an optician can fit
the corrective lenses to the dedicated frame. To assemble the
frame into the IM76 mask (see figure 4.3_1 A-C). The connector
is marked “IM76 019006607.”
4.3.2 Protection visor
For assembling, see figures 4.3_2 to 4.3_3, and figure 4.3_4 for
disassembling. The protective visor is marked “019006609.”
Attention: Do not use the IM76 mask with any other
corrective glasses, as it will interrupt the sealing between
the wearer’s skin and the IM76 mask.
2.6.2 Protective Visor for ballistic and UV-protection
IM76 can be equipped with an additional visor for ballistic and
UV-protection. The visor can be clicked-on by the user (see
Section 4.3.2 Protection visor).
3. Application and Limitation
The IM76 mask can be used as part of a complete respiratory
protective device. To form a complete respiratory protective
device, it must be combined with an appropriate filter, an
appropriate negative pressure self-contained breathing apparatus
or an appropriate airline equipment with negative pressure
demand valve. These devices’ instructions must be observed,
as well as any applicable local regulation.
The complete respiratory protective device protects the wearer
from inhaling harmful gases, vapors or particles (dust, smoke,
biological agents). There is a higher risk of flammability in
oxygen-enriched environments. IM76 is not intended to be
used in potentially explosive environments.
In case the wearer smells or tastes any contaminant, feels dizzy
or irritated, becomes exhausted, or faces breathing diculties,
he or she should immediately leave the contaminated area, and
remove the full face mask in a clean air environment.
Wearers with facial hair (beards, sideburns) or scars running
under the face seal, cannot expect that the leakage requirements
be achieved.
Other personal protective equipment or clothing worn by the
user shall not interfere with the seal or any other function of
IM76. This needs to be checked prior to use.
3.1 Filtering Devices
Please notice the following when used with a filter: Filtering
respiratory protective devices do not supply oxygen. They cannot
be used in oxygen-deficient environments. Oxygen deficiency
limits are usually set by national or local regulation (typical
limits are at least 17% or 19% of oxygen in the air). The filter
(type and class) has to be selected in accordance with national
or local regulations, depending on the type and concentration
of the contaminants. Some gases or vapors cannot be filtered.
Please notice the concentration limits for the use of filtering
respiratory protective devices. Particles can only be filtered by
particle filters (EN 143); gases and vapors can only be filtered
by gas filters (EN 14387). Combination filters (EN 14387) must
be used when particles and gases and/or vapors are present as
contaminants. The filter must be equipped with a male thread,
according to EN 148-1 or STANAG 4155 thread. The maximum
allowed filter mass is 500 g. Filter instructions must be regarded.
