following the instructions below (the drawing in
figure A shows the operations to be carried out in
sequence):
•
Make sure that the limit edge is clean and in
good condition (only if the electric fan has al-
ready been used).
•
Insert the filter as shown in the figure so that
the limit edge coincides with the filter sealing
gasket.
•
Manually screw the fixing ferrule to ensure ap-
propriate locking of the parts.
•
Before the decontaminating shower: snap the
waterproof cover onto the fixing ferrule, follow-
ing the direction indicated by the arrow (the
slits must be directed downwards)

BEFORE USE
It is necessary to make sure that:
1. The entire PPE has been properly cleaned and
decontaminated;
2. The correct filter assembly procedure has been
followed;
3. The corrugated hose is free of cracks, deforma-
tions, cuts or other faults (a damaged hose must
be replaced);
4. The mask is checked following the instructions
attached to the relative mask models;
5. The belt is assembled correctly in order to wear
the electric fan. The belt can be adjusted in a con-
ventional manner and the electric fan can be worn
in any comfortable position although it is recom-
mended to position it on the back with a moder-
ately tight belt.
We recommend checking the correct fit of the cor-
rugated hose in order to avoid entangling. (Fig.B)

After carrying out these checks and always fol-
lowing the relative instructions, proceed with the
assembly of the padded support around the belt.
The mask is put on and the tightness test is per-
formed by closing the air inlet with the palm of the
hand. Inhale and hold the breath for a few sec-
onds. Therefore, the mask is pressed against the
face by the depression created inside, the face
seal provides perfect closure, and you should not
feel the slightest leak; this can be noticed by feel-
ing the mask detaching from the face (if the mask
does not pass the tightness test, it is necessary
to carry out a complete inspection of the parts). If
everything goes properly, connect the corrugated
hose to the mask by screwing the male threaded
ferrule to the central female threaded fitting of the
mask, checking the integrity of the seal. Fasten
and secure the belt around your waist. Turn on the
BLS 2600next electric fan and proceed to the work
area.
DURING USE
Appropriate levels of protection can only be
achieved if the mask is constantly worn in the con-
taminated area. During work, any interference with
the tightness of the face seal must be avoided; do
not pull the hose or perform any other action that
could affect the proper seal of the mask. The in-
structions below must be followed in order to en-
sure the required level of protection:
1. Make sure that the filter has not been perforated
by any foreign objects;
2. Make sure not to exceed the maximum duration
