MAINTENANCE
3.Pull out the sub-efficient filter, clean it with
vacuum cleaner once in 3 months when filter
indicator lights on with buzzer sound “Pi-Pi-Pi-...”.
Replace it once in 6 months when filter indicator
lights on with buzzer sound “Pi-Pi-Pi-...”. (Fig.15)
4.Install back the filters and close the maintenance
board by twist hand screw. Please make sure that
the arrow direction on sub–efficient filter is same
as the “Air flow” mark on name plate. (Fig.15)
5.Turn on main switch, press filter reset button with
sound of “Pi-”, then filter indicator and buzzer
sound will be off. Close the control box cover by
twist hand screw.(Fig.16)
Please fill in beginning time on
new filter before replacing.
Please replace sub-efficient filter by Panasonic
Model
FV-FL0815NL1
or
FV-FL1315NL1
. If you do
not use the Panasonic filter will result in poor
performance.
Note
PRACTICAL GUIDE TO INSTALLATION
Properly insulate the area around the fan to
minimize building heat loss and gain. (Fig.17)
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.

Insulation
Foil tape tightly
covers all metal
duct joints.
(Glue PVC joints)
A short piece of flexible
duct helps alignment
and absorbs sound.
Use clamps plus mastic
or approved foil faced
tape at all flex joints.
6 inch roof jack,
wall cap, or soffit vent
with backdraft damper
Mechanically connect duct to
termination and seal with mastic
or approved foil faced tape
2-3 ft straight run before elbow
In attic installation,
caulk box to drywall
