3.2 Precautions during transportation and storage
3.2.1 Precautions for transportation
· Do not get under the lifted fan. The fan may fall onto you.
· Ask a specialist company to move and place the fan in
consideration of the center of gravity and its mass.
· Before hoisting the unit, refer to the catalogue or external
dimensions drawing etc. to confirm that the mass of the fan does
not exceed the load limit of the hoisting equipment.
· Do not hoist the entire fan using the hook on the motor or any
other parts not intended for the purpose.
(1) When hoisting the fan, wind rope or wire rope on the motor base or the fan casing.
(2) Use as long ropes and wires as possible so that the fan can be lifted at an angle of 90° or
less, which prevents the fan from being deformed/damaged by the lifting load.
3.2.2 Precautions for storage
(1) Protect the unit so that rust does not form during storage before installation, assembly or
starting operation. In particular, take measures to protect the bearings from rain water and
dust, for example by covering them with a vinyl sheet.
(2) Store indoor-type motors and other electrical devices indoors.
Also for equipment for outdoor use, protect its wiring and cable openings against moisture.
3.3 Precautions for the location of installation
Install the fan in a place where the following conditions are satisfied:
(1) The fan of standard type is intended for the indoor use. To install it outdoors, choose a place
not exposed to wind or rain water. Furthermore, install the fan in a location where it will not
suck in rain water.
(2) Well-ventilated place with minimum exposure to dust or moisture
If you install the unit in a fully enclosed room, such as a machine room, install a ventilator so
that the room temperature does not increase due to the heat generated by the motor.
(3) Place with an ambient temperature of 0°C to 40°C
(4) Place that is not accessible by unauthorized persons or that is impossible for them to
operate the fan at.
Take measures to prevent unauthorized persons from having access to the fan, for example
by installing a barrier.
(5) Place where the fan can be easily and safely inspected and repaired.
Ensure that there is enough space for assembly, disassembly and repairs of the impeller
and other parts. If fan is installed indoors, make sure there is a doorway large enough to
carry the fan in and out of the room.
(6) In case of installing the fan indoors, provide the margin at the entrance so that the fan can
be moved or transferred.
(7) If it is necessary to frequently replace or repair fans or impellers due to corrosion or wear,
consider using minimal hoisting equipment.
Caution
Do not place any objects that may obstruct ventilation or any
combustibles around the motor.
They may prevent heat from escaping, thus resulting in overheating
or fire.
