Decommissioning

The bladder-type accumulator is a component that must not be decommissioned.
For this reason, the chapter does not contain any information in this manual. How
to disassemble and replace the bladder-type accumulator is described in chapter
11 "Disassembly and replacement".
Disassembly and replacement
11
Discharge the accumulator via the discharge facility of the system. Please note
that the pre-filling pressure still exists on the gas side after hydraulic relief
Please decide whether a remaining gas pressure in the bladder-type accumulator
is required or reasonable.
For safety reasons, we recommend to discharge the gas pressure and to clearly mark
this on the accumulator, if the system is decommissioned for a longer time or forever.
In order to keep the accumulator depressurized, the gas valve insert must be removed.
