3. Safety Instructions
Read the operating instructions thoroughly before
installation, commissioning, maintenance, repair
and storage, and observe them. Failure to observe
the operating instructions may result in damage to
the valve or the parts of the system connected to
it.
In particular, in the case of explosive atmospheres,
any failure to observe the operating instructions
may result in an explosion.
The system operator must make these operating
instructions visible and easily accessible to ope-
rating and maintenance personnel.
Compliance with applicable standards/legal requi-
rements must be enforced. This particularly applies
to plant safety and environmental protection.
A list of such standards, etc. appears in the annex
by way of example.
Before starting installation, maintenance and repair
work, the hydraulic system must be depressurized
and power must be disconnected from the elec-
trical installation.
In addition, the electrical installation must be secu-
red so that power cannot be restored unexpected-
ly.
The valve may become hot during operation. To
avoid risk of burns, do not touch the valve surface.
The system operator must monitor both the am-
bient temperature as well as the uid temperature
and cool the oil if necessary in order to the keep
within the maximum temperatures set out in these
operating instructions (see technical data). In this
connection, observe the relevant directions in the
operating instructions of the supplier (solenoid
system).
Any leaks occurring at the valve must be rectied
immediately.

Work on the valve
Work relating to the installation and commissioning
of the valve may only be carried out by qualied
persons. Qualied persons are dened as persons
who, on the basis of education, experience and
instruction, have sufcient knowledge of applicable
requirements and accepted rules of the technolo-
gy.
Throughout any installation, commissioning, main-
tenance and repair work, it is the responsibility of
the operator to ensure that there is no risk of ex-
plosion.
Before starting such work, the operator has to
ensure that tools and equipment are only used if
they do not damage the valve and they do not
leave behind residues that are inammable.
In addition, clean the valve before starting such
work, in particular removing dust, liquids and other
deposits. Cleaning should be done using a lint-free
cloth.
Tools may not be used if they might cause a static
charge on use.
Throughout any installation, commissioning,
maintenance and repair work, it is the respon-
sibility of the operator to ensure that there is
no risk of explosion.
Before removing the valve the hydraulic
system must be depressurized and power
must be disconnected from the electrical
installation.
