INSTALLATION
Proper insulation around the fan to minimize building
heat loss and gain.
6’’ circular duct is recommended for
installation. 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.

Preparation:
For making sure the damper would be closed by gravity
when fan is power off. If choosing suspended ceiling,
flush to ceiling and under ceiling installation, need to
rotate outlet duct connector 90
°
counterclockwise.
1.
Remove the screw on outlet duct connector
which has damper, and rotate the duct connector
90
°
counterclockwise. (Fig .F)

2.
Make sure the duct connector tab inserted to the
flange and secure the duct connector by screw.

1.
Using 4 screws (Ø 4x10), install the brackets on
the unit, and using 4 screws (Ø 4x25) secure the
unit to the joists or cross framing. (Fig. J)

Install the housing (IV) ---
Under ceiling
1.
Using 4 screws (Ø 4x10), install the brackets on
the unit, and using 4 screws (Ø 4x25) secure the
unit to the ceiling, into the studs, joists or other
solid materials. (Fig. M)

Install the housing (V) ---
Wall mounted
1.
Outlet must be positioned upward, so the
damper will be closed by gravity. Using 4 screws
(Ø 4x10), install the brackets on the unit, and
using 4 screws (Ø 4x25) secure the unit to the
wall, into the studs, joists or other solid materials.
