6. Installation and Assembly
This equipment may only be installed by a qualified technician who is familiar with the installation, monitoring and maintenance
of this type of equipment, and uses suitable tools.
Mec anical
• To ensure safe operation, the equipment must be firmly fixed.
• The installation must prevent contact with the fan's impeller through the use of grilles, accessories, or by installing a
connecting tube of a suitable length.
• Sufficient space must be provided for opening the hatch cover (Fig. 4 and 5).
• Do not connect the elbows close to the equipment's connecting flanges or clamps.
• When connecting the ducts, ensure that the airflow direction is correct in accordance with the arrows indicating flow
direction through the equipment (Fig. 1 and 2).
• The installation must be such that the weight of the duct system is not supported by the equipment.
• If there is a possibility of water condensing in the equipment, external preventive measures must be taken.
• nce the mechanical assembly is complete, it is important to check that the impeller turns freely, with no friction or
tension.
Electrical
• Check if the equipment is connected to the power source in accordance with the instructions on the cover of the
connection box.
• For the electrical supply connection for this fan, special cable certified as compliant with fire regulations must be
used, of a suitable cross-section for the current the fan uses.
• IMPORTANT: When the equipment is controlled by reducing the voltage, the motor current may be higher than the
rated value.
• Check if the electrical characteristics stated on the plate correspond to the power supply.
• An external protective component must be connected (a relay, magneto-thermal protection system or fuse), in
accordance with current regulations.
• The equipment's earth connection must be connected.
• If the motor speed control is used, it must be guaranteed that the motor will operate correctly.
Start-up
• After starting up the motor, it is important to check that the motor is turning correctly, without vibrations or unusual
noises.
• A check must be made to ensure that the motor's actual power consumption does not exceed the level stated on the
equipment's label and that it does not heat up excessively.
• The machine must not be switched on and off intermittently, as this could damage the winding of the motor or the
insulation, due to overheating.
7. Maintenance
Maintenance must be performed by qualified technicians.
• The bearings are greased and sealed for life. Nevertheless, changing them about every 25.000 hours effective
running time is recommended.
• If the fan is not equipped with an air filter, the only maintenance required is to clean the impeller; this must be done
at least once every six months.
• Care must be taken when cleaning the impeller, in order not to affect its balance.
• It is not advisable to use chemical cleaners or aggressive substances, as they could damage the equipment.
• If a part must be replaced, consult the distributor.
For products wit single p ase, motor 400ºC / 2
• Make regular inspections each 6 months.
• All manipulations done to the motors must be held with no electrical tension at the installation. Ensure the motor is
disconnected from the electrical system.
• bserve the external side of the motor from the fan or any kind of installation where it might be installed. Clean the
motor externally; all kind of dust accumulation or obstruction, which could be found at the refrigeration wings and
protector, must be taken out.
• Clean the fan or the equipment where the fan is assembled.
• Check the electrical resistance of each phase. Notice it has to be the same in all phase.
• Disassemble the motor and check the winding visually, making sure there is no humidity nor condensation in any
part of it. Winding insulation must be higher than 10MΩ. If not, clean and dry out the stator winding.
