　　Charging
　　　　The pre-charge pressure must be less than the operating pressure engraved on the accumulator shell.
　　　　It is important to ensure the accessibility for a charging and gauging device.Concentrator table
　　　　Pre-charge pressure must be checked before operation (see paragraph on "accumulator recommendations" below)
　　　　Use only nitrogen (N2, minimum quality I).
　　　　If the nitrogen pressure of the installation connected - for the purposes of charging - to the accumulator is greater than the
　　　　Maximum acceptable pressure engraved on the accumulator, it is essential to install a pressure regulator between the bottle and
　　　　The hose.
　　　　The influence of temperature on charging pressure should be taken into consideration.
　　　　A reference table is available from HYDRO LEDUC on request.
　　　　Start-up
　　　　Check that the hydraulic installation is able to withstand the maximum pressure engraved on the accumulator.
　　　　After the hydraulic connection to the circuit, the pipe work must be bled carefully. Use the safety and shut-off blocks described.Limestone dryer
　　　　Use
　　　　The maximum hydraulic pressure must never exceed the operating pressure (PS) engraved on the accumulator shell: check
　　　　Using appropriate equipment (see page 15, charging and gauging kit).
　　　　The volumetric ratio (V
　　　　0–V2)/V0 must not be exceeded, see the technical description for each accumulator.
　　　　Bleed the pipe work of any air.
　　　　The accumulator must operate within the prescribed extreme operating temperatures.
　　　　Maintenance and control
　　　　Before intervening in any circuit which has a gas filled pressure vessel, the pressure must be discharged from the circuit.Cone crusher manufacturer
　　　　Check the nitrogen pressure regularly; see the "accumulator instructions" below, and regarding charging equipments.Cement making machine
　　　　Check regularly that there is no external corrosion.
　　　　Recommendations concerning accumulators
　　　　Extract from instructions included with each accumulator delivered:
　　　　How our accumulators are delivered
　　　　- Either: pre-charged to a storage pressure of around 5 bars. In this case, before use charge to required nitrogen pressure using
　　　　The charging assembly (VGL 4).
　　　　Check the V 10 / V 15 valve or charging screw is airtight. Put the V 10 / V 15 back in place.
　　　　- Or: pre-charged with nitrogen to the pressure corresponding to that calculated for the working conditions of the application.
　　　　In this case check that the precharge pressure marked on the label on the accumulator corresponds to the necessary calculated
　　　　Pressure
　　　　Frequency of checks
　　　　The pre-charge pressure p
　　　　0 marked on the accumulator must be checked each time the accumulator is assembled in a system,
　　　　And after every service. At least one check must be made during the first week of service.
　　　　The pre-charge pressure of the accumulator should also be checked at least once during the first week of service. Provided no
　　　　Gas leak is observed a further check should be made around 4 months later. Provided at this check there is still no gas leak, an
　　　　Annual check thereafter may be considered sufficient.
　　　　Checks
　　　　Ensure before any checks that the accumulator has been isolated from the circuit and decompressed on the oil side.
　　　　Use the LEDUC VGL 4 gauging device.
　　　　NOTE: use a manometer with a measuring range compatible with the nitrogen pressure you want to check.
