1 GENERAL INFORMATION

1.1 SYMBOLS
This is a SAFETY ALERT SYMBOL.
When you see this symbol in the manual be
alert to the potential for personal injury and
follow the instructions carefully.
This is an ELECTRICAL SAFETY ALERT
SYMBOL.
WARNING
Instructions with this symbol are critical for
the correct
maintenance and decommissioning of the
aerator.
However all the instructions should be
followed carefully to ensure the safe and
reliable running of the aerator for the whole
of its working life.
1.2 GENERAL INFORMATION
Check that the equipment detailed in the
delivery documents corresponds to the
effective contents of the consignment and
that these are undamaged.
Thoroughly review all instructions and warnings prior to
performing any work on this pump.
The manual and all the enclosed documentation, including
the safety decals, supplied with the aerator are an
important part of the machine itself and should be kept
available for consultation for the whole of its working life.
The decals could be stuck into the maintenance and
operation manual. No part of this documentation may be
reproduced or copied in any form without written
authorization from the manufacturer.
1.3 WARNING
Please read all the documentation enclosed with the
product in order to ensure safe operation and maximum
performance. The following instructions are pertinent to
the aerator used in standard mode and under normal
operating circumstances. Special features, identified in the
product code, may lead to differences to the standard
manual instructions, and where necessary the manual will
be supplemented as appropriate.
In accordance with our company policy of continuous
product improvement, the manufacturer may modify
documentation data and the product itself without any
prior notice.
Failure to follow the instructions contained in the
documentation or improper use or modification that have
not been approved by the manufacturer invalidates the
guarantee and precludes the manufacturer from any
responsibility for damage to persons, animals or property.

2. SAFETY

Before carrying out any operations make sure the electrical
parts are disconnected from the power supply.
This radial submersible aerator is designed for industrial,
building site or residential use and therefore maintenance
must be carried out by trained, qualified personnel using
the correct tools and equipment.
The aerator may be transported, installed and run by non-
specialized personnel as long as they have studied this
manual and any other documentation enclosed with the
product thoroughly.
Safety, accident prevention and environmental
safety instructions contained in this manual and
any other documentation enclosed with the
product,
restrictions must always be observed when
carrying out each single operation. Given the
nature of the liquids being aerated it may be necessary to
protect skin from direct contact by wearing or using
appropriate protective clothing or accessories.
For safety reasons and to protect the terms of the
guarantee, use of the product should be suspended in case
of any failure, breakdown or sudden variation in
performance.
During installation avoid accidental contact liable to cause
harm to persons, animals and/or property.
Inspection and maintenance procedures must be carried
out in such a way as to avoid any form of risk arising from
a possible product fault.
Please consult the chapter on "Movement and Storage" to
ensure safe movement and storage.

3. DESCRIPTION AND OPERATION

3.1 TECHNICAL
DETAILS AND APPLICATIONS
AJ submersible aerators provide an extremely flexible and
versatile new system of mixing and aerating sewage with
all the advantages of high rates of oxygenation, low noise
levels, excellent reliability,
installation. They also benefit from being able to run on
atmospheric air, oxygen-enriched air and pure oxygen and
thus do not require cumbersome, expensive air diffusion
systems.
The AJ submersible aerator consists in a submersed motor
that powers a rotator. The movement of the rotator creates
a vacuum that sucks air in from a suction chamber.
The air and liquid are forcefully mixed in the discharge
piping and discharged in radial jets, further mixing them.
This process ensures that AJ aerators achieve a very high
level of oxygenation and mixing. Moreover the AJ pumps
operate on the floor of the tanks, making sure that all the
sewage is aerated and preventing stagnant areas typical of
other systems.
The induction motor with its squirrel cage impeller is
submersible with an IP 68 level of protection.
Stainless steel screws and camshafts on all models ensure
that they are reliable even when used to aerate moderately
aggressive sewage.
Installation of the AJ submersible aerator is extremely
simple; it only has to be placed on the floor of the tank
(fig. 18 page 40) and does not require anchoring or
supports. Stability is ensured by the weight of the pump
itself and its low centre of gravity. The chain (fig. 19 page
41) hooked to the aerator and attached to the air suction
