3.2.2. Precautions for storage
(1) Take protective measures for the unit against rust during storage until it is installed and
assembled. In particular, take measures to prevent the bearings from rain water and dust,
such as covering them with a vinyl sheet.
(2) Store indoor-type motors and other electrical devices indoors.
For equipment for outdoor use, also 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) This fan is intended for indoor use. If you use it outdoors, either install it in a location not
exposed to the wind or rain, or protect the motor, bearing, and other critical parts with covers.
Furthermore, install the fan in a location where it will not suck in rain water.
(2) A well-ventilated place with minimum exposure to dust or moisture
If you install the unit in a fully closed room, such as machine room, install a ventilator so that
the room temperature does not increase due to the heat generated by the motor.
(3) A place at an ambient temperature of 0°C to 40°C
(4) A place where no unauthorized persons are able to enter or operate the product.
Take measures to prevent unauthorized persons from having access to the fan, for example,
by installing a barrier.
(5) A place where the fan can be easily and safely
inspected and repaired.
Secure a space wide enough to replace pulleys and
align the centers.
In the case of the split type casing, secure a space
wide enough to place the upper casing, the impeller
etc. and perform assembly, disassembly, and repair
work.
(6) If you install the fan indoors, ensure that the room
has a doorway that is wide enough to allow the fan
to pass through.
(7) If it is frequently necessary to replace or repair
large-sized fans or impellers due to corrosion or
wear, consider using minimal hoisting equipment.
Caution
Do not place any combustibles or objects that may obstruct
ventilation around the motor.
The cooling system may be prevented from working, which may
result in overheating or fire.
