How do you store a bladder accumulator?

​If the period of storage up until commissioning is no longer than 3 months, it is sufficient for the pre-charged accumulator, which is moistened on the inside with hydraulic fluid, to be stored in a cool, dry place, protected from direct sunlight. The accumulator can be stored in any position. To prevent contamination from entering the accumulator, make sure that the hydraulic connection is plugged. If the accumulator is to be stored for longer than 3 months, discharge the pre-charge down to 2 bar to prevent the bladder from becoming deformed. When commissioning the accumulator, allow the hydraulic fluid to flow in slowly in order to protect the bladder. If the accumulator is intended to be stored for longer than one year, it is advisable to disassemble it and store the accumulator and bladder separately.
