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 environments 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 substances.
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 breathing 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 nausea.
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 particles. 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-darkening filter in order to protect it against permanent damage.
The MigADCplus-Air helmet assembly is similar as described in the section MigADCplus
HELMET AND HEADGEAR ASSEMBLY. Besides some additional integrated parts,
(airduct, hose connector (W) and air grill (Q)), which are to be assembled by the
manufacturer only, the MigADCplus-Air helmet has also a hose holder (X), face seal
(Y) and a pair of washers (Z).
Hose holder (X) needs to be fixed onto the headgear (D) between the headgear (D) and
the nut (C), as shown on figure 1. The hose holder is designed in a way to allow use on
either side of the headgear, depending on the type of CleanAIR power unit.
Face seal must be properly assembled with the MigADCplus-Air helmet. It's position
related to the helmet and the headgear is evident from figure No.1, while exact position
related to the MigADCplus-Air helmet, airduct and hose holder is precisely described in
the next section FACE SEAL REPLACEMENT.
► WASHERS ASSEMBLY
In order to assure adequate sealing in the hood and meeting the safety standards, the
MigADCplus-Air must be additionally equiped with a pair of washers. The washers are
attached into the two upper inner pins of the external control frame.
► FACE SEAL REPLACEMENT
Both available versions of face seal (Standard and Flexi) have exactly the same
plastic face seal holder, so the replacing procedure is the same for both. In
order to be able to observe the details better, the assembly schemes will show
the face seal holder without the face seal (fabric part).
1. Remove the headgear in the oposite order as described in the section MigADCplus
HELMET AND HEADGEAR ASSEMBLY.
2. Pull the lower part of the face seal holder to release it from the airduct (1.).
3. Release the face seal holder from the two outside upper latches (2.).
4. Pull the face seal holder from the two inside upper latches (3.).
5. Take the new face seal and push the inner upper side of the face seal holder into the
two upper inside latches (4.).
