Product-related warnings

Manipulation of pressurised components
DANGER
Pressurised components such as the ends of pipes, may
become detached with force due to manipulation and the
resulting pressure surge may cause life-threatening injuries.
► All work on the device is only permitted to be carried out
when depressurised.
► With all described procedures, the valves should always be
opened and closed slowly. Never unfasten or tighten hose
lines and pipe screw connections under pressure.
CAUTION
The door of the Air Guard may only be opened when the
device is in a depressurised state.
► If it is not, there is a risk of injury due to lines flying around.
Other hazards
DANGER
Do not use this device in potentially explosive or flammable
atmospheres. The device is not approved for use in explosive
atmospheres. Under certain conditions, an explosion could be
the result.
CAUTION
Risk of injury and equipment damage.
All work on the Air Guard may only be performed when the
device is voltage-free.
► Disconnect Air Guard from the power supply and secure it
against unintentional activation. Only begin work in
Air Guard after this has been done.
CAUTION
Risk of injury when using the device with contaminated
breathing air
► The quality of the air supply must meet the requirements for
breathing air according to DIN EN 12021, and only oil- and
grease-free tools may be used for all work.
CAUTION
Risk of equipment damage due to non-permissible pressure
range of the breathing air supply
If the breathing air supply provided by the operator side is
under a too high pressure or opened too quickly, the device
could be damaged.
► Observe the permissible pressure range of max.
10 bar (LP) and max. 300 bar (HP) for the external
breathing air supply and always open all valves on the
breathing air supply slowly.
NOTICE
The measured values for the absolute moisture of the
breathing air supply are displayed for a gas temperature of
20 °C regardless of the current temperature of the gas.
