• Close the hood with the outer frame.
Insert the lower protrusions in the lowest hole
of the hood and push the upper part of frame in
the hood so that the upper protrusions hook in
the upper holes (two clicks).
The CA – 20 hood can only be combined with
approved ADF 110 x 110 mm in size! - see the list
of parts and accessories.
For more information and recommendations see
the enclosed manual from the manufacturer.
5.7. Welding hood CA – 22
A protection polycarbonate foil 0.75 mm thick
is available for protection of the ADF. The foil
is fitted from both the outer and inner side of
the cartridge and prevents spray balls from
sticking to the visor. The inner foil is inserted
straight in the cartridge, the outer one is to be
inserted in front of the ADF in the hood frame.
Before installing protective foils, peel off the
thin cover films from their both sides.
Always use protection foils in welding hoods,
otherwise the ADF will be damaged during
welding!

Putting on the face seal:
• Start in the middle of the lower edge
and fix the face seal symmetrically along the
circumference to the hook-and-look fastening
on the inner side of hood.
• Pull the air duct through the face seal
and screw in the headband.
• Fix the face seal with the side straps to
the headband.
For hygiene reasons, discard the old face seal
immediately after replacement so that it cannot
be reused. The face seal must not be washed!
Washing causes loss
impregnation securing incombustibility!!!
5.7.2. Protection foil replacement
We recommend using protection foils for all
CleanAIR hoods. The foil protects the hood
visor and prevents it from damaging and
soiling. An early replacement of foils extends
the hood life, provides a continuously good
through view and makes work easier.
Warning: Do not clean foils dry, otherwise they
may be scratched easily and their transparency
will be reduced. Foils can also concentrate
electrostatic discharges and, therefore, the
through view may be reduced in a dusty
environment.
5.7.3. Forehead strap replacement:
The soft forehead
headband prevents pressure damage and
increases comfort during use. Replace it as
necessary; it can be unfastened easily owing
to its fixing with a velcro fastening.
The CA – 22 hood can only be combined with
approved filters 90 x 110 mm in size! - see the list
of parts and accessories.

the helmet sits on the head comfortably, but
firmly. If the helmet is not in use or during
