4.7 Installation
Bladder accumulators are preferably to be
installed vertically, with the gas charging
connection pointing upwards. Other installation
positions are possible. However, performance
may be impaired.
Irrespective of the installation position, the

shown on the type code label or accumulator
shell must be accessible and legible.
Allow an area of approximately
150 mm x 150 mm above the gas charging
connection for fitting the charging unit.

form on the bladder accumulator.
