1.3 Warnings/limitations
Warnings
The equipment must not be used
• In the power-off state. In this abnormal situation a
rapid build-up of carbon dioxide and depletion of
oxygen may occur in the head top and no
protection is given.
• If the surrounding air does not have a normal
oxygen content.
• If the pollutants are unknown.
• In environments that are immediately dangerous to
life and health (IDLH).
• With oxygen or oxygen-enriched air.
• 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 SR 500 must always be used with two particle
filters or two combined filters.
• If the user is exposed to very high work intensity, a
partial vacuum may occur in the head top 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.
• 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.
• The filters must not be fitted directly to the head
top.
• Only use Sundström filters.
• The user should take care not to confuse the
markings on a filter to standards other than EN
12941:1998 and EN 12942:1998 with classification
of the SR 500 fan unit when used with this filter.
