Electric Motors; Maintenance - Repairs; Replacement Parts - S&P JETLINE Serie Betriebsanleitung

Check all rotating parts have free, unobstructed movement.
Check there are no foreign bodies inside the fan or that can be drawn
into, or fall into fan.
Check the structure is complete and has no damage.
Check installation and area is safe and energise fan and start motor.
Check that the impeller and airflow direction is correct, check current
does not exceed fan equipment nameplate data.
After two hours of operation, check that all fixings are tight and adjust
if necessary.

ELECTRIC MOTORS

For fans with S&P sourced/sub-supplier motors, the motor instruc-
tions will be included with the fan equipment for extra assistance to
Installer. Refer these for further motor guidance. Electrical connec-
tions are made in accordance with connection diagram in the motor
instructions and/or inside motor terminal box.
Many S&P fans are supplied with a cable gland for typical electrical
power cable connection, to assist installation. However, if Installer
uses a cable requiring a differing cable gland, this is to be supplied by
the Installer, no alternative is offered by S&P. The Installer is respon-
sible to ensure that cable, and cable gland, are suitable and safe for
application according to country regulations.
Ensure system operation is safe in event of power cut/power outage/
disruption to power supply. If ventilation is stopped due to disruption
to power supply, ensure no risk due to excessive temperature (electri-
cal heater). Care may be needed when restarting fan after disruption
to power supply.
Most motors are supplied with permanently greased or sealed for life
bearings and do not require re-lubrication. However, if motors with
re-greasing facility are supplied, then follow the instructions in the
specific motor Instruction manual and nameplate supplied.
Warning: Do not mix different types of grease.
Motors with speed control via Variable Speed Drive (VSD) Frequency
Inverter, should not be run in excess of nameplate speed. In general
applications, we recommend not to run at less than 20Hz and never
less than 20% of nameplate speed without reference to manufactu-
rer, since this may damage the motor.
If you are using cable longer than 20 meters between the drive and
the motor, add output sinusoidal filter.
If you are using cable longer than 50 meters between the drive and
the motor, add output EMC filter.

MAINTENANCE - REPAIRS

Maintenance/repairs must be carried out by competent personnel
and in accordance with applicable International, National and Local
regulations. Fan equipment should be electrically isolated and loc-
ked out before any work started.
Fan equipment should be regularly cleaned, frequency depending
upon service load and application, but no less than every 6 months.
Fan equipment for dust applications may require more frequent clea-
ning to ensure safe operation. Cleaning should include all areas whe-
re dust can accumulate in the fan equipment.
Special attention should be made to any unusual sounds, vibration or
temperature. If any problems are detected the fan equipment should
be stopped immediately and cause inspected. The impeller and bla-
des should be regularly checked for damage that could cause imba-
lance in the moving parts.

REPLACEMENT PARTS

Do not start working until all relevant safety procedures have been
read, understood and actioned correctly.
Ensure that personnel are competent for work required, spare parts
are correct for application, tools and materials to be used are availa-
ble and safe for environment.
Identify components, bolts, fixings to be removed, and identify loca-
tion to ensure replaced in same location, this can be done by marking
with number/letter/colour to bolt fixing and any associated spacing
material to identify location. This is especially important for motor
fixings to supports, and impeller shaft fixings to supports, where pac-
king/spacing/shim material is used to adjust motor/impeller shaft
center line, and hence final impeller position.
GOOD PRACTICE, GOOD/BAD INSTALLATION ARRANGEMENT
Fans are designed and performance tested in accordance with stan-
dard duct arrangements. Thus they should be installed correctly
without any adverse installation effect. Typically fans should be
installed so that air entry is clear, unobstructed, non-turbulent and
discharge does not hinder airflow, since air turbulence adversely
affects impeller performance.
PUTTING OUT OF SERVICE AND RECYCLING
Disposal must be carried out by competent personnel and in accor-
dance with applicable International, National and Local regulations.
Isolate fan equipment and any associated electrical equipment and
lock off. Remove electrical connections.
Disconnect fan equipment from duct connections and cover connec-
tions with plastic sheet to prevent exposure to any residue material in
fan equipment, and any contamination of ducts.
Dismantle and dispose in accordance with applicable National and In-
ternational laws and regulations, those parts whose service life has
expired.
EEC legislation and our consideration of future generations
mean that we should always recycle materials where possible; plea-
se do not forget to deposit all packaging in the appropriate recycling
bins. If your device is also labeled with this symbol, please take it to
the nearest Waste Management Plant at the end of its servicable life.
The fan unit is mainly made of steel, copper, ferrite, aluminium and
plastic. These components should be recycling in the following cate-
gories:
− Steel and iron
− Aluminium
− Non-ferrous metals
− Plastics
− Insulating materials
− Cables
− Electronic scrap
