OPERATING INSTRUCTIONS: Marley Engineered Products Air Circulators can be used alone,
or in conjunction with air conditioning unit to circulate cool air or to force it into other areas. This
Marley Engineered Products Air Circulator can also be used in the winter to force the warm air
trapped near the ceiling, down toward the floor level for warming comfort.
NOTE: If your fan is experiencing vibration problems, please refer to the re-tracking instructions
shown below.
CLEANING: Disconnect power to the unit. Use a screw driver to remove the front guard from
the rear guard by prying apart the hooks holding the two together. Use a damp cloth and mild
detergent to clean the guards and the blade. Take care not to bend the blades. Use the same
prying method to hook the guards back together.
RE-TRACKING OF FAN BLADE: Due to possible rough treatment to the blade during shipping,
the blade should be re-tracked to assure proper balance and to eliminate vibration.
CAUTION: ALWAYS UNPLUG THE FAN BEFORE RE-TRACKING. NEVER OPERATE THE
FAN WITHOUT ALL GUARDS PROPERLY ASSEMBLED.
To re-track the blade, use a tape measure, or similar device, to measure the distance between
the back guard and the leading tip of each fan blade. Insert the tape measure from the back of
the fan through the guard and rest it against a guard rib. Measurements should be taken by
leaving the tape measure at the same location while rotating the fan blades to measure their
distances, one at a time.
If the distances vary between blades, use a screwdriver to remove the front guard from the rear
guard by unhooking the hooks from the rear guard. The distances should then be equaled by
carefully bending the blade angles AT THE BLADE HUB near the motor shaft. DO NOT
ATTEMPT TO BEND BLADE TIPS, since this will contribute to vibration problems you may have.
After re-tracking the blade, assemble front guard and check for balance of blade by operating
the fan.
