Correct Installation; Maintenance And Repair - S&P HGTT-V Instruction Manual

antee adequate values for "maximum voltage peak",
"maximum rate of voltage rise" and "peak to peak".
Otherwise, add a du/dt filter after the VSD.
− The fan must operate at full speed.
• If an earth connection is necessary, check that it correct-
ly connected and that adequate thermal and overloading
protection has been connected and adjusted to the corre-
sponding limits.
• If a ventilator is installed in a duct, the duct must be exclu-
sively for the ventilation system.

CORRECT INSTALLATION

• These units are designed to be installed in-line within a
ducted ventilation system.
• When installing the unit, for optimum operation ensure
there are no obstructions within the ducted system that
may cause excessive static pressure developments. En-
sure that the fan is installed at a minimum of one, ideal-
ly two, diameters length clear of any fitted accessories,
changes of ducting diameter or wall partitions to reduce
perturbances to the flow of air into /out of the fan.
• When using flexible ducting connectors ensure that that
the connectors are installed directly in-line with the fan
and pulled tight to eliminate slackness.
• Consider antivibration mounts.
• The fans are designed to be connected to ductwork match-
ing flanges (or similar) through ALL of the holes provided.
• Before connecting the unit to the electrical supply, ensure
that the impeller turns freely and there are no obstructions
to the airflow.
• All impellers are manufactured from high grade die cast
aluminium and dynamically balanced during assembly.
• Do not alter or modify the angle of the blades. Any unau-
thorised alteration to the impeller blade angle could have
dangerous implications to the intended operation of the
fan. Any alteration to the product by any means will invali-
date the guarantee.
STARTING UP
Before starting up the machine, make sure that:
• The apparatus is well secured and the electrical connec-
tions have been carried out correctly.
• No loose material or fitting remains can be sucked up by
the ventilator. If the ventilator has been mounted in a duct,
make sure it is clear of loose material.
• The earth fittings are adequately connected.
• The electrical safety devices are correctly connected, ad-
equately adjusted and ready for use.(Same installation for
ventilation and smoke extraction in case of fire)
• The wire and electrical connections inputs are correctly
sealed and water-tight.
When starting up the machine, make sure that:
• The impeller or wheel turns in the correct direction.
• Check there are not abnormal vibrations or noises, and
that the amp levels do not surpass those defined in the fan
label.
• After running for two hours, check that all fixings are prop-
erly tightened.
• If any of the electrical safety devices jump, the apparatus
must be quickly disconnected from the mains supply. The
whole installation should be carefully checked before try-
ing to start up the unit again.

MAINTENANCE AND REPAIR

• Maintenance and repair operations must be carried out
by competent personnel, following the manufacturer's
indications and in accordance with each country's appli-
cable safety regulations.
• All operations must be agreed with the manufacturer and
be properly defined.
• Before handling the unit, make sure it is disconnected from
the mains supply even if it has previously been switched
off. Prevent the possibility of anyone else connecting it
while it is being handled.
• The product range is designed to operate in the case of
fire. It is therefore recommended that the fan is checked
at least every six (6) months for electrical and mechanical
operation.
• These inspections should be carried out bearing in mind
the unit's working conditions, in order to avoid dirt or dust
accumulating on the impeller, turbine, motor or grids. This
could be dangerous and perceptibly shorten the working
life of the unit.
• If the fan will operate for emergency only, it must run at
least 15 minutes every month, to ensure proper homoge-
neity of the bearing grease components.
• Attention must be paid to abnormal sounds, vibrations or
temperatures. If a problem is detected, the fan must be
stopped immediately and the cause inspected.
• While cleaning, great care should be taken not to destabi-
lize the impeller or turbine.
• Most motors are equipped with sealed for life bearings. For
motors provided with grease nipples, follow the instruc-
tions in the motor's O&M manual and its plate.
• Warning: Do not mix different types of grease.
PUTTING OUT OF SERVICE AND RECYCLING
EEC Standards, together with the responsibility
we should assume with future generations in
mind, oblige us to recycle all the materials we
can. Therefore, please deposit all left-over ma-
terial and packaging in their corresponding recy-
cling containers and hand in the replaced machines to the
nearest handler of this type of waste product.
The unit is mainly made of steel, copper, ferrite, aluminium,
plastic and rockwool. These components shou ld be recycled
in the following categories:
- Steel and iron
- Aluminium
- Non-ferrous metals
- Plastics
- Insulating materials
- Cables
- Electronic scrap
