Basic safety notes
Risk of severe injuries
The equipment is under pressure and hot during
operation. 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 body material and the
gaskets and sealings. 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.
Working with dangerous (contaminated, hot
or pressurized) fluids.
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.
Risk of property damage or malfunctions
Malfunctions will occur if the equipment is
installed in a wrong position or with the flow
arrow pointing in the opposite direction of the
fluid flow. This may result in damage to the
equipment or the installation. Make sure that
the flow arrow on the equipment body matches
the indicated direction of the fluid flow in the
pipe.
If the body material is unsuitable for the fluid,
increased wear may occur and fluid may
escape. Before mounting the equipment make
sure that the body material is suitable for the
fluid used in your installation.
Incorrect temperature settings can affect the
proper performance of the installation.
Consequently, parts of the installaton could be
damaged.
Make sure that only qualified and trained
personnel change the closing temperature
setting.
Do not adjust a closing temperature that is
below the factory setting. For more
information on default factory settings see
chapter
“Adjusting the closing temperature“
on page 10.
An inclined installation position can lead to
increased wear on the equipment. Please
contact the manufacturer if the equipment
cannot be installed with the cover pointing
vertically upwards or hanging downwards.
