GENERAL INSTRUCTIONS

CAUTION!
The 'SCL K' blowers - exhausters have been
designed and manufactured for use in an industrial
environment, operated by qualified personnel and
as a unit to be incorporated in a machine, which
conforms to the CE Machinery Directive.
The 'SCL K' blowers - exhausters, like all
machinery and equipment with live and moving
parts, can be a source of serious hazards unless
properly used and protected.
The user is committed to ensure that:
All handling, assembly, installation, connection,
maintenance and repair operations are undertaken
by qualified personnel. Such people who by their
background, training and experience as well as
through their knowledge of statutory regulations,
legislation, safety
conditions are able to carry out any necessary
steps avoiding all possible risks to health and
damage.
Such personnel should have received all the instructions and
information, including any local legislation, and will follow
them during the performance of any operation.
It shall be forbidden for unqualified personnel to carry out any
operation, even indirectly, on the machines and equipment.
During the installation, all the prescribed working conditions,
including any possible local requirements, shall be observed.
Additionally it is forbidden to put the unit in service before the
machines of which they are a part are declared to conform to
the CE Machinery Directive.
The user must be aware that in operation:
•
the surface temperatures can reach 160°C;
•
the unit cannot contain high internal pressures, no greater
than Ps max referred to in PERFORMANCE TABLE - page
3-4;
•
there is small loss of the fluid handled;
•
the level of noise may be unacceptable in certain
applications.
1.1

CONDITIONS OF USE

The 'SCL K' blowers - exhausters are designed for the continuous
movement of air or non-explosive, non-hazardous and non-
flammable gases and for service in non-explosive environments.
Solid particles, however small, including dirt can cause serious
damage; therefore it is essential that such substances should be
removed from the gas by suitable filters upstream of the inlet.
(Units which do not have an adequate filter ARE NOT COVERED
BY THE GUARANTEE).
The maximum driving pressure must never be exceeded
(Maximum differential pressure of PERFORMANCE TABLE -
page 3-4).
UNDER NO CIRCUMSTANCES OPERATE THE UNIT WITH THE
GAS INLET OR OUTLET CLOSED.
APPLIES TO THE UNITS WITH THE CAPACITY FOR HIGHER
DRIVING PRESSURES.
Protect the units with an appropriate safety valve.
The performance characteristics are liable to variations due to the
following factors:
•
Differences of the suction or discharge pressures from the
reference conditions (1013 mbar);
measures and operating
IN PARTICULAR THIS
•
Operation in a system with both a low suction pressure and a
high back pressure;
•
Operation with a gas at a different temperature or of a different
specific gravity from the reference data (1.23 kg/m
•
Variations in the rotational velocity of the fan with respect to
the reference value.
Both the gas inlet temperature and the ambient temperature must
be in the range of -15°C to +40°C.
At the same time, ensure that the unit has good ambient
ventilation, especially when subjected to severe operating
conditions.
A unit subjected to frequent starting or to high ambient
temperatures may be prone to overheating and in such cases
further information should be requested.
Similarly, where flammable gases may be present, information
must be requested for alternative models certified for the Ex.
environment.
1.2

STORAGE AND SHIPPING

Store the unit in a dry place, preferably in original packaging.
Do not remove the protection plugs from the ports.
Avoid stacking anything on top of the packaging.
To move the packed boxes, use the largest pallet or support base
possible to obtain the maximum stability.
On all occasions handle the units with care and avoid sudden
impacts.
Lifting eyes are provided to unpack units weighting more than
25
kg.
(The weight of the unit is M in PERFORMANCE TABLE - page 3-
4).

INSTALLATION

1.3.1 'SCL K' BLOWER - EXHAUSTER
It is important that the unit is installed in a well-ventilated
environment where the temperature does not exceed 40°C.
If outside, protect the unit from direct sunlight and avoid the
possibility of water collecting in the external crevices especially
when installed with the axis vertical.
IMPORTANT!
Ingress of foreign matter, however small, will cause serious
damage.
Such matter includes dust, sand, masonry debris, impurities in the
tubes, cutting burrs or filings, welding or soldering slag and
splatter, metal burrs and any residues from sealing and making the
tube connections.
The unit can be mounted with the axis in any position.
As supplied, the unit is balanced and will not transmit vibrations,
however it is recommended that it be mounted on vibration
damping supports.
To connect the machine to the piping, remove the flanges and
connect using flexible hoses. Do not use rigid connections as
these may cause stress and harmful vibrations. Insert gaskets and
tighten.
Remember to protect the inlet with suitable filters.
If it is necessary to regulate the flow, install a bypass valve (refer to
section 1.5).
Only remove the plugs on the ports when making the final
connections.
