Routine maintenance must be done every year. Please wear gloves during the cleaning work. Never use gasoline, benzene, thinner or any other such chemicals for cleaning the ventilating fan. Do not immerse motor in water when cleaning. Do not soak resin parts in water over 140 °F (60 °C).instruction 11

  1. Clean grille. (Don’t put into hot water. Use non-abrasive kitchen detergent, wipe dry with clean cloth.) (Fig.15)
  2. Remove one mounting spring. (Fig.16)
  3. Remove the sensor unit.
  4. Remove the other mounting spring to remove the grille.(Fig.17 )  Remove dust and dirt from fan body using a vacuum cleaner. (Fig.17)instruction 12
  5. Using a cloth dampened with kitchen detergent remove any dirt from fan body. Wipe dry with clean cloth. (Fig.17)
  6. Reinstall grille.


Properly insulate the area around the fan to minimize building heat loss and gain. (Fig.19) Loose fill or batt insulation can be placed directly over the fan housing in the attic. Our fans and fan/light combination units do not create excessive heat that is a common problem with recessed light fixtures or some competitor’s fan/light combination. Our efficient, cool running motors and our fluorescent lamps do not create enough ambient heat to be subjected to these limitations. The ducting from this fan to the outside of the building has a strong effect on the air flow, noise and energy use of the fan. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated air flow.
