Installation
All accumulators shipped from the factory will be
precharged to a nominal pressure in order to seat the
poppet valve on the hydraulic port. In this case the
precharge will not be listed on the label. However, in
some cases they will be shipped with a nitrogen
charge, the value of which will be marked on the label/
nameplate.
Keep the hydraulic port covered to keep out foreign
material until ready to make the hydraulic connec-
tions.
The accumulator should be mounted within 25° of
vertical with the hydraulic port on the bottom. It should
also be rigidly mounted using appropriate mounting
hardware, which is shown in
the Accumulator Accessories section of this catalog.
The hydraulic circuit, which contains a connection to
the accumulator, should be designed so that it auto-
matically discharges all hydraulic fluid from the
accumulator when the equipment is turned off.
