All the equipments manufactured in Sistema AZUD are subject to strict quality control tests and are
manufactured under a productive process which complies with the requirements of the standard ISO
9001/2000.
Sistema AZUD is also committed with the environment, and is certified under the Environmental
Management System of the standard ISO 14001.
This manual includes instructions and warnings to a correct installation, operation
and maintenance of the Equipment.
2.1. Exclusive Use of the filtration Equipment.
Sistema AZUD filtration equipments have been designed to exclusively filter water,
according to the Operational Conditions indicated in the Technical data and the
Industrial label of the Equipment. In any case to the filtration of dangerous liquids
(understood as such the specific in the charter 2 of article 2 of Directive
67/548/CEE, of 27th of June of 1967), or liquids for food use.

2.2. Identification of the product.
In AZUD each filtration equipment is identified by an industrial label, placed in one of the main
manifolds, with the serial number. With this number the factory can always identify the equipment.
The modification or elimination of this label cancels any warranty; and impedes the
identification of the Equipment.
The industrial label indicates: manufacturer, address, model, year of manufacturing, serial
number, max. Pressure, max. Temperature and conformity with the Directive of Pressure
Equipments 97/23/CEE
The filters of the equipment,
are identified with a label in
which is indicated the model,
year of manufacturing, serial
number and max pressure.
AZUD HELIX AUTOMATIC consists of a filtering element which comprises
grooved discs, that allow the retention of particles of a size bigger than the
required filtration grade. The Equipment combines the advantages of the
disc filters with those of the helicocentrifugal effects of the helix.
AZUD grooved discs combine on-surface filtration and in-depth filtration
to achieve the maximum precision and safety in the filtration.
The particles are retained through the channel of the discs.

FILTRATION

The system carries out two independent phases called FILTRATION PHASE and
BACKFLUSHING PHASE.
TECHNOLOGY
Valve 1 Valve 2
Filtration
Stage
Backflushing
Stage
Through the feeding of the three-ways
valves chambers, the inlet of water to the
filter closes, communicating the inner of
the filter with the drainage manifold,
starting the backflushing cleaning.

The end of the backflushing coincides with the closure of the drainage outlet and the opening of
the outlet manifold, allowing water coming from the feeder manifold to come into the interior of
the filter and in this way, to re-establish the filtration phase conditions.
In the filtration process, water is carried from the feeder
manifold (inlet manifold), through the backflushing three-
way valve (valve 1), to the interior of the filter through its
inlet.
Once the water come in the filter, the only track the water
of its interior can follow, are the discs channels whose
discs form a stack. This stack is compressed by the spring
action and the hydraulic power itself.
The filtered water goes through the 2” hydraulic valve
and goes to the rest of the installation.
The filtered water given by the Special
backflushing T, is introduced in the filter.
The available hydraulic power is used to
overcome the pressure exerted by the
spring on the discs stack generating in
this way its own decompression due to
the piston displacement (raising).
The discs release makes possible its
rotation due to the tangential projection
of the water coming from the feeder
bars which at the same time are used
as structural shoulder of the discs stack.

2. With the Control Unit, when the minipilot valve is un AUTO position. Said Control Unit activates the
backflushing cycle under one of the four possible orders: pressure differential existing in the
equipment, following a preestablished frequency of time between backflushes,bydirectaction on
the keyboard or by external signal. The programmer, which incorporates the Control Unit, closes the
contact which supplies tension to the NC solenoid, converting the electricsignalinanhydraulicsignal
which is in charge of the feeding of the three-way valves chambers. In this way, is achieved the same
addressing of the flow of water that the one explained in the control manual.
The start of the backflushing process takes place in two ways:
1.When the ¼” three-way valve (minipilot) is put on OPEN position by hand. In
this position, the minipilot valve allows water to flow from the inlet manifold to
the chambers of the two three-way hydraulic valves . In this way, water is not
allowed to come into the filter through the feeder manifold and it allows water to
flow through the outlet. At the same time, the interior of the filter communicates
with the drainage manifold.
