Basic safety notes
Risk of severe injuries
The equipment is under pressure during
operation and may be hot. Before carrying out
any work on the equipment make sure that the
following requirements are met:
The pipes must be depressurized (0 bar).
The fluid must be completely removed from
the pipes and the equipment.
During work on the equipment the
installation must be switched off and
protected against unauthorised or
unintended activation.
The pipes and the equipment must have
cooled down to room temperature (approx.
20 °C).
If the equipment is used in contaminated areas
there is a risk of severe injuries or death caused
by harmful substances in or on the equipment.
Before working on the equipment make sure
that it is completely decontaminated. Always
wear the protective clothing prescribed for
contaminated areas when working on the
equipment.
The equipment must only be used with fluids
that do not attack the material and the gaskets
and sealings of the equipment. Otherwise leaks
may occur and hot or toxic fluid could escape.
The equipment and its component parts must
only be mounted or removed by qualified
personnel. A qualified person must be
acquainted with and experienced in the
following:
Making pipe connections.
Selecting suitable lifting gear and
understanding the rules for its safe use.
Working with dangerous (contaminated, hot
or pressurized) fluids.
If installation or removal work is carried out
carelessly the springs may shoot out of the body
and injure personnel.
Always wear safety goggles when mounting or
removing the springs.
When working on the springs make sure that no
uninvolved persons are standing in close vicinity
of the equipment.
If the admissible temperature and pressure
limits are exceeded the equipment may be
destroyed and hot or pressurized fluid may
escape. Make sure that the equipment is only
operated within the admissible service range
and limits.
For more information on limits and pressure &
temperature ratings see name plate and the
section "
Technical Data
".
Risk of minor injuries
Sharp edges on internals present the danger of
cuts to hands. Always wear industrial gloves
when servicing the equipment.
If the support of the equipment during
installation is insufficient the equipment might
fall down, thereby causing bruises or injuries.
Make sure the equipment is safely held in place
during installation and cannot fall down. Wear
protective safety footwear.
Information on property damage or
malfunctions
Malfunctions will occur if the equipment is
installed in a wrong position or with the flow
pattern in the opposite direction of the fluid flow.
This may result in damage to the equipment or
the installation. Make sure that the flow pattern
indicated on the name plate matches the
direction of the fluid flow in the pipe.
If the material is unsuitable for the fluid,
increased wear may occur and fluid may
escape. Make sure that the material is suitable
for the fluid used in your installation.
The equipment may get damaged by pressure
impulses, even if the admissible nominal
pressure PN is not exceeded.
Make sure that the equipment is not subject to
pressure impulses or heavily pulsating flow.
If the dampers are subjected to stress the
equipment may get damaged. Do not use the
dampers to lift the equipment. Do not step on
the dampers.
If the dampers are adjusted incorrectly,
malfunctions may occur or the equipment may
get damaged. Do not change the factory
settings of the dampers.
