MAINTENANCE

IMPORTANT: MAKE SURE THE POWER IS OFF AT THE

ELECTRICAL PANEL BOX BEFORE YOU ATTEMPT ANY REPAIRS.

REFER TO THE SECTION “CONNECT WIRING”.

Because of the fan’s natural movement, some connections may become

loose. Check the support connections, brackets, and blade attachments

twice a year. Make sure they are secure. (It is not necessary to remove

fan from ceiling.)

Clean your fan periodically to help maintain its new appearance over

the years. Use only a soft brush or lint-free cloth to avoid scratching

the finish. The plating is sealed with a lacquer to minimize discoloration

or tarnishing. Do not use water when cleaning. This could damage the

motor, or the wood, or possibly cause an electrical shock.

You can apply a light coat of furniture polish to the wood blades for

additional protection and enhanced beauty. Cover small scratches with

a light application of shoe polish.

There is no need to oil your fan. The motor has permanently lubricated

bearings.

TROUBLESHOOTING

Fan will not start.

1. Check circuit fuses or breakers.

2. Check line wire connections to the fan and switch wire connections

in the switch housing. CAUTION: Make sure main power is off.

Fan sounds noisy.

1. Make sure all motor housing screws are snug.

2. Make sure the screws that attach the fan blade bracket to the motor

hub is tight.

3. Make sure wire nut connections are not rubbing against each other

or the interior wall of the switch housing. CAUTION: Make sure main

power is off.

4. Allow a 24-hour “breaking-in” period. Most noise associated with

a new fan disappear during this time.

5. If using an optional light kit, make sure the screws securing the

glassware are tight. Check that the light bulb is also secure.

6. Some fan motors are sensitive to signals from solid-state variable

speed controls. If you have installed this type of control, choose

and install another type of control.

7. Make sure the upper canopy is a short distance from the ceiling. It

should not touch the ceiling.

Fan wobbles.

1. Check that all blade and blade arm screws are secure.

2. Most fan wobbling problems are caused when blade levels are

unequal. Check this level by selecting a point on the ceiling above

the tip of one of the blades. Measure this distance.

Rotate t

he fan

until the next blade is positioned for measurement. Repeat for each

blade. The distance deviation should be equal within 1/8”.

3. Use the enclosed Blade Balancing Kit if the blade wobble is still

noticeable.

4. If the blade wobble is still noticeable, interchanging two adjacent

(side by side) blades can redistribute the weight and possibly result

in smoother operation.

WARNING: TO REDUCE THE RISK OF PERSONAL INJURY, DO

NOT BEND THE BLADE ARM WHILE INSTALLING, BALANCING

THE BLADES, OR CLEANING THE FAN. DO NOT INSERT FOREIGN

OBJECTS BETWEEN ROTATING FAN BLADES.
