Installation Precautions
1.
Installation of this fan requires a proper device which can support the weight of fan plus
installers, such as an aerial work platform, and at least two (2) installation persons.
2.
Please switch off all power before installation to avoid the risk of electric shock.
3.
All wiring construction must comply with the national electrical codes, standards and the local
electrical law, and must be installed by professional technicians or personnel.
4.
An earth leakage circuit breaker (<30 mA) should be installed between the appliance and the
power switch.
5.
The power switch must be fitted with a fuse (
≥
20 A).
6.
The yoke must be securely mounted to the ceiling or beam.
7.
Do not damage electrical wiring and other hidden utilities/devices during installation.
8.
To avoid fire or other hazards, make sure that the wires are completely inside, no wire is to
be exposed outside the fan.
9.
Do not bend the airfoils when installing the fan.
10.
The fan model covered by the installation instructions must comply with this installation
manual and all national/local electrical codes to avoid personal injury or property damage.
11.
Please ensure that this application is equipped with AC single phase 220-240 V before
installation.
12.
All fan parts must be
≥
2 ft (0.6 m) from all obstructions. The fan installation area must be free
of obstructions such as lights, cables, sprinklers, or other building structure components.
13.
The distance should be at least 0.98 ft (0,3 m) from the top of the winglet to the ceiling and
with no obstructions in this area.
14.
The fan must be installed so that it is at least 8.17 ft (2,5 m) above the floor.
15.
Multiple fans must be spaced at a center-to-center distance that is no less than 2,5x the fan
diameter.
16.
The fan should not be located near air supply outlets or exhaust inlets of other HVAC
equipment. Air supply outlets/inlets can be configured to deliver air away from the fan and
outside the swept area of the fan.
17.
If the fan is mounted at the same level or higher than an HVAC diffuser, the winglets must be
at a distance that is at least 1,5x the measure of the fan’s diameter. If the fan is mounted
below an HVAC diffuser, the winglets must be at a distance that is at least 2x the measure of
the fan’s diameter.
18.
Please contact local fire experts regarding requirements for the minimum clearance to
combustibles.
19.
The fan inlet or other return air point that produces negative pressure should be bigger than
1x the diameter of the ceiling fan. This system will reduce the airflow of the fan.
20.
Proper systems orientation will provide an enhancement to the Indoor Air Quality and
occupant comfort. Please refer to the illustration below.
