ASSEMBLY INSTRUCTIONS
4. Install DUCT AND BLOWER ASSEMBLY
a.Install duct from the inside of the housing;Fix the duct by the tab.
b.Fix the BLOWER ASSEMBLY to the housing by 3 screws.
5. INSTALL ROUND DUCTWORK
a. Connect the round ductwork (not included) to the damper/duct connector, and run the
ductwork to a roof or wall cap (not included).
b. Using tape (not included), secure all the ductwork connections so that they are air tight.
c. Insulated flexible duct is recommended for the quietest possible installation. If rigid
duct is used, a short (1-3 feet) section of insulated flexible duct will ensure quiet
operation.
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.
RETROFIT INSTALLATION

2. Fold mounting ears flat against housing.
3. Enlarge ceiling opening to 9-1/2" by 9-1/2", leave ductwork and wiring in place.
