Maintenance
For quiet and efficient operation, long life, and attractive appearance - lower or remove grille and vacuum interior of unit with the dust
brush attachment.
The motor is permanently lubricated and never needs oiling. If the motor bearings are making excessive or unusual noises, replace
the motor with the exact service motor. The impeller should also be replaced.
Keep all electrical components away from water. Do not use corrosive chemicals or water in excess of 60C (140°F) to clean plastic
parts.
4. Install Junction Box And Ductwork
Remove junction box cover and connect electrical wiring (refer to wiring diagram),
replace the junction box cover.
Connect the round ductwork (not included) to the damper/duct connector, and run the
ductwork to a roof or wall cap (not included). Using tape (not included), secure all the
ductwork connections so that they are air tight.
The ducting from this fan to the outside of 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.
Install the Grille
Install ceiling material to complete the ceiling construction.
Then, cut around the fan housing.
To attach the grille assembly to the fan housing. Pinch the grille springs on the sides of
the grille assembly, and position the grille into the housing with the grille springs in the
appropriate slots. Push the grille assembly towards the ceiling to secure.
