BEFORE YOU START
Turn O Power at Breaker
Contact an electrician if you are uncomfortable
performing electrical work. A licensed electrician
must install the fan if required by local code.
Prepare Fan Site and Gather Hardware
CAUTION
Do not use the fan with a dimmer switch.
Outlet Box*: Make sure your outlet box is suitable for fan support. If there is not an
outlet box at the fan location, install one on a ceiling joist or beam. You will need
to supply two 10-32 screws for attaching the fan mounting bracket or plate to the
outlet box.
Concrete Ceiling: Depending on your mount type, you will need to supply three or
four anchor bolts** for attaching the fan mounting bracket or plate to the ceiling. If
required by your local building and safety codes, you will also need to supply an
anchor hook** for the safety cable. See pages 4–5 for hardware specifications and
installation details.
Wood Ceiling Joist*: You will need to supply two corrosion-resistant 12-11 x 45mm
hex head timber screws with seal for attaching the fan mounting bracket or plate
directly to the joist. If required by local code, mount or embed an outlet box into
the joist. The outlet box must be suitable for fan support.
Covered Outdoor Locations***: Damp-rated fans installed in covered outdoor
locations must have fixed/permanent full overhead coverage extending at least
2ft (0.6 m) out from the airfoil tips on all sides.
*Mounting to an outlet box or a wood ceiling joist is not applicable in Singapore.
**If anchor bolts and anchor hook are included with your fan, use them for concrete mounting.
***When installing the fan in a covered outdoor location, use only light kits marked “Suitable for Use in Damp Locations.”
Gather Tools

BEFORE YOU START
Check Ceiling Slope (Universal Mount)
Consult the table below to make sure you have the appropriate downrod length
for your ceiling slope. Universal Mount fans can be installed on flat or sloped
ceilings with an angle no greater than 33° (approximately 8:12 roof pitch). For
minimum clearance guidelines, consult the Important Safety Instructions booklet
included with this installation guide.

Drill three Ø 8 mm holes in the pattern shown (Fig. 1). The hole depth should not
exceed 46 mm (Fig. 2).
Remove dust from holes. Insert anchor bolts* into holes. Strike the heads of the
anchor bolts with a hammer, ensuring bolt sleeves are flush with ceiling surface.
Position mounting bracket on anchor bolts. Ensure all anchor bolts are fully
tightened to expand and lock the anchors.
If required by local building and safety codes, install an anchor hook* for the
safety cable. Drill an Ø 8 mm hole for the anchor hook. The hole depth should not
exceed 46 mm (Fig. 2). Remove dust from hole, and then insert the anchor hook
and fully tighten.

1. Install airfoils
Make sure the sticker color on each airfoil matches the corresponding
sticker color on the motor unit.
Moving clockwise, slide each airfoil edge under the lower cover, align the mounting
holes with the holes on the motor unit, and secure with the airfoil hardware. Make sure
the grommets are positioned correctly in the holes (Fig. 1).

2. Install downrod
No Uplight
If not installing an uplight, align holes on downrod with holes on motor bracket. Position
downrod wiring harness so that it is on the same side of the motor shaft as the motor
unit wiring harness. Position ground wire and safety cable so that they are on the
opposite side of the motor shaft as the motor unit wiring harness. Secure downrod with
the lower mounting hardware (Fig. 2a).
Uplight
Align holes on downrod with holes on motor bracket. Position downrod wiring harness,
ground wire, and safety cable so that they are on the opposite side of the motor shaft
as the motor unit wiring harness. Secure downrod with the lower mounting hardware
(Fig.2b).

3. Install lower safety cable and ground wire
Install safety cable and ground wire lugs with unpainted screws and lock washers (Fig. 3).
4. Install uplight (optional)
Skip this step if you are not installing an uplight.
Make sure wiring harnesses are as close to downrod as possible so that they do not
interfere with uplight installation (Fig 4.1).

UNIVERSAL MOUNT INSTALLATION
Skip this step if you are not installing an uplight.
If you purchased the UV-C option, install the UV-C LED boards on the
uplight before installing the uplight on the fan. Refer to the instructions
packaged with the UV-C LED boards.
Align rectangular cutouts in center of uplight with bolts on downrod. Make sure uplight
wiring harness and motor unit wiring harness are on opposite sides of downrod. Slide
uplight down the downrod until it stops (Fig 4.2). There will be some space between
the uplight and the top of the motor unit.
Uplight not compatible with damp-rated fans. Light kit weight: 1.5 lb (680 g).

Do not over-tighten the mounting ball screw.
Slide mounting ball over downrod (Fig. 8.1).
Insert 6 mm steel pin into hole at top of downrod, and then slide the mounting ball
upward, seating the steel pin in the inner slots (Fig. 8.2).
Insert wedge into mounting ball and secure with screw (Fig. 8.3). Tighten screw enough
to prevent movement between the mounting ball and downrod, but do not over-
tighten. Make sure rubber plug at top of downrod is still in place.

11. Wire fan
WARNING
Disconnect power to fan location before wiring fan.
Do not connect fan to a damaged power source. Do not attempt to resolve
electrical failures on your own. Consult a qualifi ed electrician if uncertain of the
electrical installation of this fan.
Wire fan as shown on the following pages using the wire connectors. If your fan
packaging did not include an EMI fi lter*, refer to Fig. 11a. If your fan packaging included
an EMI fi lter, refer to Fig. 11b. The EMI fi lter is included only for certain regions and fan
diameters.
Attach green and yellow ground wire to mounting bracket with the unpainted screw.
Connect wiring harness from power supply to wiring harness from downrod, making
sure that the wiring and safety cable are routed in the same direction.
Carefully tuck wiring into outlet box or building structure. Ensure wire connectors are
turned upward and that wires are spread apart with grounded conductors on one side
of the outlet box/mounting structure and ungrounded conductors on the other side.
