Safety instructions

Diaphragm accumulators are pressure devices with inner gas load. They operate in pressure
retaining applications and machines.
WARNING: The permissible operating conditions (in particular max. working pressure,
min./max. working temperature) specified in the technical documentation and on the
name plate must be observed.
Never install the diaphragm accumulator in a machine or system under hydraulic system
pressure. Prior to repair and maintenance work on the diaphragm accumulator, the gas pre-
charge pressure must be completely relieved. The accumulator shall cool down sufficiently
before starting work.
CAUTION:
temperatures during operation.
WARNING: Work on improperly pressure-relieved Diaphragm accumulator or its
machine/system may result in death, serious injuries or property damage!
CAUTION:
out by trained and qualified persons.
Do not make any unauthorized modifications to the diaphragm accumulator. This will result in
an immediate expiry of the operating permit! This includes the use of non-approved or third
party spare parts.
DANGER: There is a risk of bursting during mechanical processing!
DANGER: There is a risk of explosion during welding and soldering work!
Diaphragm accumulators may only be charged with nitrogen of Class 4.0 (N2-vol.%>99.9).
Oxygen and air are not permitted as filling gas, as they can cause a fire or an explosion.
DANGER: When filling with oxygen or compressed air, there is a risk of explosion!
The diaphragm accumulator may only be operated with fluids of fluid group 2. Flammable,
oxidizing, explosive, toxic or corrosive fluids of fluid group 1 must not be used.
WARNING:
cause skin damage, eye injuries or poisoning when inhaled.
Risk of Burns! Diaphragm accumulators may generate high surface
Commissioning as well as repair and maintenance shall only be carried
Danger to health when handling hydraulic fluids! Pressure fluids can
