Classification | Internal

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: 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.

Fig- 2 Fig- 4

Push the free end of cable (2) thro' the hole in

the down rod (thro' which supply

wires are not run) till it comes out of the

shackle end.

Fold the free and of the Cable (2). Raise the

canopy to appropriate position. Likewise place

the condensor cover in it's desire position.
