3. Basic Instructions For Use
Read these Instructions for Use carefully and
follow them. The user must be perfectly
familiar with the correct use of protective
equipment.
•
The user must know the type of
contamination and its concentration in the
ambient air.
•
The oxygen concentration in the
surrounding of a person using the filtration
system must not drop below 17% in
Europe. In the Netherlands, Belgium, UK,
Australia, and New Zealand it must not
drop below 19%. For the other countries
obtain their requirements.
•
Do not use in explosive environments.
•
Follow the instructions in the Instructions
for Use of Clean-AIR filter units and the
Instructions for Use of filters.
•
Only use with the filter-ventilation unit
switched on. Filters must not be
connected straight to the hood!
•
The filtered air overpressure inside the
protective headtop is the primary
protective factor preventing the ambient
air contaminants from penetrating. In the
case of filtration systems with hoods, the
protection of respiratory organs with the
fan switched off is low or none. Also, the
carbon dioxide concentration may
increase and the oxygen content may
decrease inside the hood.
•
To put the hoods on comfortably, they
have an adjustable headband (straps).
•
Make sure that the sealing line of the
headtop fits tightly to the face (in hoods,
tightness can be adjusted using the self-
tightening clamp under the chin). Only
then may the perfect protection level be
secured. The protection factor may be
reduced if the user has hair or beard
extending to the face sealing part. If it
gets to the sealing line, the penetration
will increase and the protection provided
by the system will decrease.
•
During very hard work, a vacuum may be
created inside the headtop during inhaling
and thus the protection factor may be
reduced temporarily.
4. Cleaning and Disinfection
•
Every time you finish your work, clean the
headtop, check its individual parts and
replace damaged parts.
•
Cleaning must be carried out in a well-
ventilated room. Avoid inhaling harmful
dust settled on individual parts!
•
For cleaning, use tepid water (up to
+40°C) with soap or some other non-
abrasive detergent and a soft brush.
•
It is forbidden to use agents containing
solvents for cleaning.
•
After individual parts have been cleaned
with a damp cloth, they must be wiped dry
or left to dry at the ambient temperature.
•
Common preparations, such as Ajatin,
Incidur, etc., may be used for the
disinfection of parts coming into contact
with skin.
•
The auto-darkening filter in the welding
hood is only to be cleaned with a dry,
clean or only slightly moistened cloth (in
clean water, soap solution or alcohol).
•

recommendations see the enclosed
manual from the manufacturer.
5. Maintenance, Spare Parts Replacement,
and Cleaning
Before using a new product, always check that
the equipment is complete and that no damage
occurred during transport.
5.1. Hoods CA – 1, CA – 2 and CA – 10
Hoods are supplied with a foil protecting the
visor against damage during handling and
transport. The foil is sewn in the hood and it
must be removed carefully.
A separately supplied foil 0.1 mm thick is
designated to protect the shields of these
hoods. To fix it to the shield, the foil is provided
with self-adhesive tapes on sides.
Material:
Hood – polyamide floated with polyurethane
Visor – cellulose-propylene
Protective foil – diacetate
5.1.1. Protection foil replacement:
•
Peel off the old foil, wipe the headtop
aperture with a damp cloth to remove dust
from it.
•
Remove the protective paper from the
self-adhesive tape on one side of the new foil,
apply the foil on the shield and stick.
•
Remove the protective paper from the
self-adhesive tape on the other side of the foil,
stretch the foil and stick.
•
If working in a heavily contaminated
environment, the foil can be stuck from up and
