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 the 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.
