Limitations On Use - Clean Air CA-20 GDS Manual Del Usuario

Important
Please read and remember the following instruc-
tions before use to assure your own safety. If you
have any questions, please contact the manufac-
turer or your distributor.
Keep the manual for future reference. The welding
hood should be used only for the purposes listed
in this manual.
1. Introduction
Welding hood CA-20 is adapted for use with powered
air purifying respirators (hereinafter PAPR) CleanAIR®
or with continuous flow compressed air line breath-
ing apparatuses (hereinafter "compressed air sys-
tems CleanAIR®) and thus provides protection of
the respiratory tract. It also provides protection
against harmful ultraviolet / infrared radiation and
welding spatters.
CleanAIR® is a system of personal respiratory pro-
tection based on the principle of overpressure of
filtered air in the breathing zone. The respirator
is placed on the wearer's belt and filtrates the air
which is taken in from the surrounding environ-
ment and then delivers it through the airduct into
the protective hood. The overpressure prevents
contaminants from entering the breathing zone.
This mild overpressure at the same time ensures
the wearer's comfort, even with long-term use,
as the wearer does not have to struggle in their
breathing to overcome the resistance of the filter.
Welding hood CA-20 is certified according to EN
166:2001, EN 175:1997-08, EN 12941:1998+A2:2008
and EN 14594:2005.
There are two variants of welding hood CA-20. The
first variant is compatible with auto-darkening filter
(ADF) Balder Grand V9-13 DS with internal control
panel. The second variant supports external con-
trol for ADF and is compatible with ADF Balder
Grand V6-8/9-13 GDS. Both variants can be op-
tionally enhanced by the build in protection helmet
(see. chapter "Hard hat assembly").

2. Limitations on use

Failure to follow these instructions will invalidate the
warranty. CleanAIR® does not accept responsibility
for any problems which may arise from applications
other than welding/grinding, or if the instructions
for use are not strictly followed.
1. Material of the hood can cause allergic reac-
tions to a sensitive person.
2. Do not use tempered mineral filters without
suitable protection foils.
3. The welding arc damages unprotected eyes!
4. The welding arc may burn unprotected skin!
5. Pay attention to checking the product before
use. Do not use, if any part of the system is
damaged.
6. Do not put the welding hood on hot surface.
7. Use only within the temperature range of -5 °C
to +55 °C.
8. Never use the hood in the following environ-
ments and under the following conditions:
• If oxygen concentration in the environment
is lower than 17 %.
• In oxygen-enriched environments.
• In explosive ambience.
• In environments where the user lacks
knowledge about the kind of dangerous
substance and its concentration.
• In environments representing an immediate
threat to the life and health.
• If you are not sure, that shade number of
your welding filter lens is suitable for your
work.
• Replace protection filter immediately, if it is
damaged, or if spatter or scratches reduce
vision.
• The hood does not protect against hard
shocks, explosions or corrosive substanc-
es.
9. Move to a secure location and take appropriate
measures when any of the following problems
occur while using the hood:
• If you feel significant increase of breath-
ing resistance or any other problems with
breathing.
• If you experience stench or irritation or an
unpleasant taste while breathing.
• If you feel unwell or if you experience nau-
sea.
10. Use certified original filters designed for your
powered air purifying respirator only. Replace
filters every time you detect change of odour in
supplied air from the respirator.
11. Filters designed for capturing solid and liquid
particles (particle filters) do not protect the user
against any gases. Filters designed for capturing
gases do not protect the user against any par-
ticles. In the workplace contaminated with both
types of pollution, combined filters must be used.
12. Protection plates, both internal and external,
must be used in conjunction with the auto-dar-
kening filter in order to protect it against per-
manent damage.
3. Control and maintenance
Lifetime of the hood and visors is influenced by
many factors such as: cold, heat, chemicals, sun-
light or incorrect use. The hood should be checked
on a daily basis of possible damage of its inside or
outside structure.
Careful use and correct maintenance of welding
hood enhances operating life and improves your
safety!
Checking before use:
• Inspect that the protection plates are undam-
aged, clean and installed correctly. Replace lens
immediately, if it is damaged, or if spatter or
