Maintenance, Repairs; Replacement Parts - S&P CRHB Serie Manual De Instrucciones

Refer these for further motor guidance. Electrical connections 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 responsible 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/dis-
ruption to power supply. If ventilation is stopped due to disruption to pow-
er supply, ensure no risk due to excessive temperature (electrical 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 spe-
cifi c motor Instruction manual and nameplate supplied.
Warning: Do not mix different types of grease.
Motors with speed control via Variable Speed Drive (VSD) Frequency In-
verter, should not be run in excess of nameplate speed. In general appli-
cations, we recommend not to run at less than 20% of nameplate speed
without reference to manufacturer, since this may damage the motor.
However, the fan shall not operate below 40% of its nominal rpm (20Hz).
If you are using cable longer than 20 meters between the drive and the
motor, add output sinusoidal fi lter.
If you are using cable longer than 50 meters between the drive and the
motor, add output EMC fi lter.

MAINTENANCE, REPAIRS

Maintenance/repairs must be carried out by competent personnel and
in accordance with applicable International, National and Local regu-
lations. Fan equipment should be electrically isolated and locked 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 equip-
ment for dust applications may require more frequent cleaning to ensure
safe operation. Cleaning should include all areas where dust can accu-
mulate 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 blades
should be regularly checked for damage that could cause imbalance 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 available and
safe for environment.
Identify components, bolts, fi xings to be removed, and identify location
to ensure replaced in same location, this can be done by marking with
number/letter/colour to bolt fi xing and any associated spacing materi-
al to identify location. This is especially important for motor fi xings to
supports, and impeller shaft fi xings to supports, where packing/spacing/
shim material is used to adjust motor/impeller shaft center line, and
hence fi nal impeller position.
GOOD PRACTICE, GOOD/BAD INSTALLATION ARRANGEMENT
Fans are designed and performance tested in accordance with standard
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 hin-
der airfl ow, since air turbulence adversely affects impeller performance.
PUTTING OUT OF SERVICE AND RECYCLING
Disposal must be carried out by competent personnel and in accordance
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 connections
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 Inter-
national 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;
please 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 plas-
tic. These components should be recycling in the following categories:
• Steel and iron
• Aluminium
• Non-ferrous metals
• Plastics
• Insulating materials
• Cables
• Electronic scrap
