1. To optimize the air delivery and avoid turbulence ceiling fan should be approx. 7 ~ 8 feet from the
ground level and 1 feet below the ceiling/false ceiling (if Applicable).
2. Minimum distance between blade tip and wall & between 2 Fans blade tip should be almost equal
or more than the fan sweep size.
3. Don’t mix the blade of one set with another set as these blades are balanced and packed as a set for
efficient performance and safety.
4. In case of false ceiling, the hole in false ceiling must be in line with ceiling hook and minimum 1
inch gap should be available all around the down rod.
5. Ensure that the down rod &fan blade are placed away from any ceiling beam for proper assembly,
follow the down rod instruction given in the diagram
IMPORTANT
The diagram of fan are just the general representation of ceiling fan and not the actual fan. Read the
instructions carefully. Open the packing and arrange the fan parts as per the numers marked on
diagram. Assemble & install fan as per the assembly, wiring diagram and written instruction. Check the
assembled fan, ensure proper installation before switching ON the fan.

Note: If pairing fails, repeat the steps after switching OFF and powering ON the fan from the mains supply
Note: Multiple fans can be paired with single remote
REMOTE UN-PAIRING INSTRUCTIONS (FAN OPERATES WITH TWO REMOTES)
INSTRUCTION 1: PCB Controller have 2 memories for remote.
INSTRUCTION 2: Remote 1 & Remote 2 both can be paired with the ceiling fan
INSTRUCTION 3: Firstly Remote 1 gets paired with PCB. Then Remote 2 gets paired. Pairing should happen within 10 secs.
Both memories of the controller are filled with Remote 1 & Remote 2. Now the fan will operate as per Remote
1 & Remote 2 command.
INSTRUCTION 4: You can remove Remote 1 from pairing list and pair the PCB with Remote 3
INSTRUCTION 5: Once you remove Remote 1 from pairing list, memory of the controller is filled with Remote 2 & Remote 3.
Now you can operate the fan with Remote 2 & Remote 3. After that, PCB won't respond to the commands of Remote 1.
SINGLE REMOTE PAIRING INSTRUCTIONS (FAN OPERATES ONLY WITH SINGLE REMOTE)
INSTRUCTION 1: If you want to operate with single remote means you want to pair the PCB with single remote you can pair, it
for 2 times within 10 seconds.
That means both the memories are filled with single remote. Now you can operate the fan with single remote
only (Remote 1).

INSTALLATION OF SUPPORT
CABLE WITH FAN
Fig- 1
CAUTION
Installation of Secondary Support Cable
The purpose of Secondary support Cable is to temporarily hold the fan with ceiling hook, in case
of failuse of primary suspension system, which may happen due to faulty installation, inadequate
tightening of fasteners like nut & bolts etc. The fan should be switched off immediately & faulty
system should be corrected before using again.
Fig- 3
Un wind the support cable (2) and remove the
metal clamp (3).
Pass the cable through the shaft hole/ support
clip 1 (Hole below Down rod assembly hole)
so that it stops at the beaded end.
Thread the Cable (2) thro' the two holes on
cable clamp (3) & then thro" the ceiling hook
(4). Loop it & thread the free and thro another
set of hole in the clamp. Ensure that the Cable
is slack & approximately about an inch losse
and in no case supporting the fan directly as
shown in Fig - 3 & Fig - 4. Then fully tighten
the clamp by tightening nut & screw to ensure
that the secondary support is rigidly held.
