correspond to the order details.
3. Verify that the test certificates (if required) are present and
correspond to the factory number on the accumulator.
4. The protective cap on the gas valve is tightly closed.

INSTALLATION AND MOUNTING
Mounting position
Piston accumulators function with maximum effeciency
and longevity when mounted vertically with the gas valve
at the top. There must be sufficient clearance in order to
mount and disconnect the charging and gauging apparatus
to maintain the nitrogen pre-charge.
MOUNTING
In accordance with the recommendations of Accumulators,
Inc., piston accumulators must be securely mounted and
vibration free using approved Accumulators, Inc. clamps and
brackets.
CONNECTION
The connection for the accumulator to the system must
be stress free and torque free, and it must be possible
to isolate the accumulator from the pressurized hydraulic
system.
STARTUP AND SAFETY
STARTUP
Prior to connecting the accumulator to the pressurized
system, the pre-charge pressure should be rechecked (if
the accumulator was pre-charged at Accumulators, Inc. the
pressure level can be found on the pressure tag.)
The level of the pre-charge pressure generally depends on
the following criteria:
•
Type of system
•
Minimum and maximum operating pressures
•
Expected changes in operating temperature
•
Intended function of the accumulator
