and periodic inspections must be initiated by the user in accordance with the applicable
operational safety regulations.
The pipelines must be dimensioned and installed in accordance with the specific
requirements according to local and national regulations.
5. COMMISSIONING
DEP replaceable diaphragm hydropneumatic accumulators are supplied from the factory
with the inflation pressure indicated on the label attached to the product (1.5 Bar - Air). To
guarantee the correct operation of the system, this value must be adjusted to a pressure
value P0, taking into account the characteristics of each installation, either by filling with air
up to the pre-charge value P0 or by venting through the filling valve in the event of needing to
reduce the initial air pre-charge to the value P0.
In the case of hydro-pneumatic accumulators downstream of the booster set (PRESSURE),
the value of the pre-charge pressure P0 shall be as follows:
In the case of hydro-pneumatic accumulators upstream of the booster set (SUCTION), the
value of the pre-charge pressure P0 shall be as follows:
P0 (Bar) = Water supply pressure in tank - (0,5 ÷ 1) Bar ≥ 1 Bar
If the value of the precharge pressure obtained is higher than 3 bar, prior to the air recharge
operation, it will be necessary to introduce water through the lower inlet/outlet connection of
the hydro-pneumatic accumulator, until the coupling, cover or lower inlet orifice is covered.
From this moment on, isolate the hydro-pneumatic accumulator from the pipe by closing
the tap or valve provided for this purpose. From this moment on, the accumulator shall be
recharged with air through the accumulator inflation valve until the Precharge P0 value is
reached.
Once the pressure has been adjusted in accordance with the above instructions and the
appropriate precautions have been taken, the accumulator is connected to the installation.
Its operation is automatic.
