1. General information
Use of a respirator must be part of a respiratory protection pro-
gram. For advice see EN 529:2005 or AS/NZS 1715:2009. The
guidance contained in these standards highlights important
aspects of a respiratory protective device program but does
not replace national or local regulations.
If you feel uncertain about the selection and care of the
equipment, consult your work supervisor or get in touch with
the sales outlet. You are also welcome to get in touch with
the Technical Service Department at Sundström Safety AB.

1.1 System description

• The SR 520/SR 530 hood can be used with the SR 500/
SR 700 fan unit.
• The SR 520/SR 530 hood and SR 540 EX shield can be
used with the SR 507 compressed air attachment. Fig. 1.
• The SR 520/SR 530 hood and SR 540 EX shield can be
used with the SR 500 EX fan unit in potentially explosive
environments. Fig. 2.
Before use, these user instructions and those for the fan units,
filters and compressed air attachment must be thoroughly
studied. The breathing hose must be connected to the fan unit
equipped with filters. The above-atmospheric pressure gener-
ated in the head-top prevents particles and other pollutants
from being admitted into the breathing zone.
1.2 Applications
The equipments can be used as an alternative to filter respira-
tors in all situations in which these are recommended. This
applies particularly if the work is physically demanding, warm
or of long duration. When selecting the head-top, some of
the factors that should be taken into account are as follows:
• Types of pollutants
• Concentrations
• Work intensity
• Protection requirements in addition to respiratory protective
device.
The risk analysis should be carried by a person who has
suitable training and experience in the area.
1.3 Warnings/Limitations
Note that there can be national differences in the regulations
for use of respiratory protective equipment.
Warnings
The equipment must not be used
• If the fan is not running. In this abnormal situation, the
equipment will provide no protection. In addition, there is
risk of carbon dioxide quickly accumulating in the head top,
which would lead to oxygen deficiency.
• if the pollutants are unknown,

and face shield SR 540 EX
• in environments that are immediately dangerous to life and
health (IDLH),
• in environments where the ambient air is oxygen-enriched
air or does not have a normal oxygen content,
• if you find it difficult to breathe,
• if you can smell or taste the pollutants,
• if you experience dizziness, nausea or other discomfort.
Limitations
• The head-tops must not be used together with peel-offs or
head covers in potentially explosive atmosphere.
• If the face seal is not firmly in contact with the face, the
pressure necessary for maintaining the correct protection
factor will not be established.
• If the user is exposed to very high work intensity, negative
pressure may occur in the device during the inhalation
phase, which may involve the risk of leakage into the
head-top.
• The protection factor may be reduced if the equipment is
used in surroundings in which high wind speeds occur.
• The seal of the head-top against the face must be assured.
This may be difficult to achieve if the user has a beard or
sideboards.
• Be aware that the breathing hose might make a loop and
get caught up by something in your surrounding.
• Never lift or carry the equipment by the breathing hose.
