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 or a third-party 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 to the outlet box.
Concrete Ceiling: You will need to supply four M6 anchor bolts* for attaching the
fan mounting bracket to the ceiling. If required by your local building and safety
codes, you will also need to supply an M6 anchor hook* for the safety cable. See
page 4 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 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.
Exposed Outdoor Locations**: Wet-rated fans installed in exposed outdoor
locations must have fixed/permanent coverage above the fan wiring cover, must
be installed in a GFCI protected branch circuit, and can be mounted to flat ceilings
only.
☑Gather Tools
*If anchor bolts and anchor hook are included with your fan, use them for concrete mounting.
**When installing the fan in an exposed outdoor location, use only light kits marked “Suitable for Use in
Wet Locations.”

BEFORE YOU START
☑Check Ceiling Slope
Consult the table below to make sure you have the appropriate downrod length
for your ceiling slope. The fan can be installed on a flat or sloped ceiling 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.

BEFORE YOU START
☑Prepare Concrete Ceiling (if applicable)
Use mounting bracket as drilling template and drill four Ø 8 mm holes in concrete
ceiling (Fig. 1). The hole depth should not exceed 40 mm (Fig. 2).
Remove dust from holes. Insert four M6 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 (Fig. 3). Ensure all anchor bolts
are fully tightened to expand and lock the anchors.
If required by local building and safety codes, install an M6 anchor hook* for the
safety cable. Drill an Ø 8 mm hole for the anchor hook. The hole depth should not
exceed 50 mm (Fig. 2). Remove dust from hole, and then insert the anchor hook
and fully tighten.
*If anchor bolts and anchor hook are included with your fan, use them for concrete mounting.

FAN INSTALLATION
1. Install mounting bracket
WARNING
Disconnect power to fan location before installing mounting bracket.
Mount only to an outlet box marked acceptable for fan support.
Secure mounting bracket to mounting structure with suitable hardware (not supplied)
(Fig. 1). Outlet box shown. Your mounting structure may dier. Mounting bracket

2. 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 qualified electrician if uncertain of the
electrical installation of this fan.
Do not use the fan with a dimmer switch or a third-party switch.
Connect wires from mounting bracket to supply power wires (Fig. 2). Carefully tuck
wiring into outlet box or building structure so that only the wiring harness is hanging
out. 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.

3. Install airfoils
Make sure sticker color on each airfoil matches corresponding sticker
color on fan hub.
Tighten airfoil screws to 22.1in·lb (2.5 N·m). Do not use power tools.
Over-tightening screws may cause airfoils to warp and void your
warranty.
Align each airfoil on fan hub, making sure sticker color on airfoil matches
corresponding sticker color on fan hub. Secure airfoils to hub with M5 x 12 mm screws
and tighten screws to 22.1in·lb (2.5 N·m) in sequence shown (Fig. 3).

11. Secure safety cable
Some local safety codes require the safety cable to be secured directly
to an existing part of the building structure (Canada, Singapore). It
may be necessary to install additional structural material to provide
attachment points. Check your local safety code if you are unsure.
