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
1. Remove wire panel and blower assembly before 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.
4. Connect wiring according to the wiring diagram.Re-install wire
panel.
5. Mounting fan

Remove the blower assembly as directed in the service parts
section of this manual to gain access to the additional mount-
ing holes.
b. Mount with hole of the flange
