6.6 INITIAL START-UP
Before starting the fan:
•
make sure you have not left any object or tool inside the machine;
•
ensure that no residuals of the installation activities remained
on the blades; the resulting fan imbalance would cause to
harmful vibrations causing rapid wear of the propeller bearing;
•
ensure that the wire mesh safety guards are securely fitted to
the machine;
•
ensure that staff keep a safe distance (at least 30 metres) from
the machine.
•
check that the electrical protection and safety devices are
operating correctly.
Once the fan has been started:
•
verify that it has been correctly installed checking to see that there is
no unusual vibration and/or noises. if there any of these are present
then switch off the machine, identify the problem and rectify it;
•
check that the fan rotation direction is anticlockwise when
viewed from the fan air inlet side; if the rotation direction is
clockwise and hence erroneous then invert the two wires in the
power line (three-phase motors).

7.1 MAINTENANCE REQUIREMENTS
The fans made by the company. are designed and manufactured
for long life even under the most severe service conditions.
Please remember however that this equipment HAS moving
parts, and as such they need to be checked regularly.
It is therefore recommended to implement a preventive
maintenance program, which will be entrusted to skilled and
competent personnel.
The daily inspection must be performed to prevent any failure
due to adverse effects of the working environment such as
temperature, humidity, dust, dirt and vibration, and other factors.
WARNING
The fan must be fixed so that the side casings are easily
removable to allow maintenance and cleaning operations.
Check that the water drain holes on the bottom panel are not
obstructed so as to ensure proper drainage.
WARNING
In the machine maintenance and inspection phases there is a
risk of entanglement and cutting of clothes, limbs, hair or other
parts of the body by the fan.
During these phases acquire the PPE, in particular safety
clothing and gloves, tie long hair back and do not wear rings,
bracelets or necklaces.
CAUTION
To ensure a high level of safety, use only original spare parts
available from your supplier. In case of using non-original parts, full
functionality and compliance with EC directives regarding electrical
safety and electromagnetic compatibility are not ensured.
WARNING
When working on the machine, it is necessary to make all
personnel are aware of this.
In the event of maintenance work, affix a warning sign onto
the power supply switch to inhibit accidental operation by a
second operator.
Regularly carry out the following operations:
•
Ensure that the inlet and outlet openings are clean and free
of objects.
•
Ensure the fan is always dry. If the fan appears wet, dry
it immediately; identify the cause and remedy to prevent
corrosion.
•
Check the cable connections and connectors. In the event of
loose connections, damaged cables, or other abnormalities,
stop the fan immediately and seek specialised assistance or
technicians.
•
Check for bolts or nuts that are loose or rusted because of
environmental conditions. In this case, tighten or replace.
•
Check for any deposits inside the equipment. In the case,
remove the deposits by compressed air jets.
The following table specifies the periodic routine checks that the
user must perform to maintain the machine in good condition.
