S&P FRC Serie Manual De Uso Y Mantenimiento página 13

- Separate, where possible, the motor and the fan (removing the belts).
- Wear suitable clothing for protection from accidents; in particular, clothing should not have any parts which may become trapped in the parts
of the fan, and, moreover, we recommend covering the hair with a special cap.
- Wear protective goggles.
- Check for the existence of a lock which prevents the involuntary starting up of the machine, and enable it.
- If no such lock exists, take all possible precautions to ensure that other people cannot start up the machine.
During maintenance, should it be necessary to remove the safety precautions, remember to place warnings of the possible hazard, and put all
the protections back in place when the maintenance operations are complete.
Inspection door can be a source of hazard, for which reason they should be secured in such a way as they can only be opened using tools. In
any case, it is absolutely forbidden to open the inspection door when the fan is in operation. If the fan is not connected to ducts of sufficient
dimension as to prevent contact by any part of the body with the parts in movement, install protection grilles of sufficient size in the inlet and
discharge.
RISKS
The fan, in accordance with that set out in the Machinery Directive, has been subjected to stringent risk analysis. Below is information for all
staff, in order to prevent possible damage to people and things.
The following risks have been taken into account in terms of safety:
FAILURE IN THE INSTALLATION
All fans which are incorrectly installed or made to operate in an inappropriate manner present a risk to people and things. Fans must be installed
by trained, expert staff. The installation must fulfil all current safety rules and Directives.
ROTATION SPEED
The fan is designed to operate safely within a specific maximum rotation speed value and noise level, as indicated in the Technical Sheets.
Never exceed these limits.
WORKING TEMPERATURE
The fan is designed to operate safely within a specific maximum temperature value and noise level, as indicated in the Technical Sheets. Never
exceed these limits, specifically for the effect of the transported gas. Ensure workers are suitably protected when transporting gas at
temperatures in excess of 50ºC.
PROTECTION DEVICES
The removal of these devices represents a serious risk. It is therefore forbidden to remove the protection devices installed in the machine.
ELECTRICAL HAZARD
The maintenance of the electrical parts should be carried out by competent staff, having read the information contained in the manual of the
electrical motor supplier. Every six months, check the earthing of all the metal parts of the machine. Avoid provisional or temporary connections
in the electrical section. Never use water to put out a fire in the electrical sections. Complete the electrical power circuit to supply the motor in
line with the corresponding regulations.
INCOMING FOREIGN BODIES
Should there be a risk of foreign bodies within the fan, it is necessary to mount interception grilles of sufficient size. Regularly check the
accumulation of foreign bodies in these grilles, and, if necessary, remove them following the instructions contained in the point SAFETY
PRECAUTIONS.
DANGEROUS GASES
Whenever the fluid to be drawn off may represent a hazard for the integrity of people (noxious and toxic gases), the fan must be fitted with
suitable sealing in order to prevent emissions. Should this not be possible, use equipment which is suitable for the type of fluid transported in
order to capture and/or suck in these gases.
NOTE: this fan cannot be used with:
corrosive gases
�
inflammable gases
�
explosive environments (ATEX)
�
INSPECTION DOORS
It is absolutely forbidden to open the inspection door whilst the fan is in operation. In order to clean the machine, once the fan has come to a
halt, it is necessary to remove the power supply and ensure that nobody can start up the machine accidentally. Then open the inspection door
by removing the attachment screws, and access the inside of the machine.
INLET AND DISCHARGE MOUTHS
It is absolutely forbidden to start up the fan if it is not connected to ducts of sufficient size as to prevent access to the parts in movement. In
the event of missing ducts at the inlet, use large oversized protection grilles (at least three times the intake power) in the inlet mouth. Once the
fan has come to a halt, remove the power supply and, having ensured that nobody can start up the machine accidentally, remove the conducts
and/or protection networks, withdrawing the attachment elements.
INERTIA
When the power supply is removed, the fan impeller will continue to rotate through inertia. Before carrying out any type of intervention in the
machine, ensure that the fan impeller has come to a complete halt.
DISMANTLING
At the end of the useful life of the fan, eliminate all non-reusable materials, in line with current regulations, classifying them in accordance with
their typology.
