INSTALLATION INSTRUCTIONS
CAUTION: MAKE SURE POWER IS SWITCHED OFF
AT SERVICE PANEL BEFORE STARTING INSTALLATION.
SECTION 1
WARNING: DO NOT INSTALL OVER A TUB OR
MOUNT IN A SHOWER STALL ENCLOSURE.
4. Choose the location for your unit. To ensure the best
air and sound performance, it is recommended that
the length of ducting and the number of elbows be
kept to a minimum, and that insulated hard ducting
be used. Larger duct sizes will reduce noise and
airflow restrictions. This fan will require at least 7"
of clearance in the ceiling, and will mount through
drywall up to 3/4" thick. The fan can be mounted
directly to the joist using the mounting tabs on the
side of the housing or between
16" on center joists using the
4 provided mounting rails.
5. Remove the electrical
knockouts using a straightblade screw driver (Figure 3).
SECTION 2
Preparing the Unit
1. Unpack fan from the carton and confirm that all pieces
are present. In addition to the unit you should have:

1. Run wiring from approved wall switches carrying
the appropriate rating. One neutral (white), one
ground (green or bare copper), and three hot (black,
red, blue leads connected to the switch, one for
each function). Secure the electrical wires to the
housing with an approved electrical connector. Make
sure you leave enough wiring in the box to make the
connection to the fan’s receptacles.
2. Connect the white wire from the house to the three
white wires from the fan. Connect one hot (black)
wire from the wall switch to the black wire from the
fan (this is the fan control). Connect second hot (red)
wire from the wall switch to the red wire from the
fan (this is the heat control). Connect the third hot
(blue) wire from the wall switch to the blue wire from
the fan (this is the light control). Connect the ground
wire from the house to the green wire from the fan
(Figure 9). Use approved methods for all connections.
SECTION 6
Completing the Installation
1. Insert the plug from the heating unit into the
receptacle marked “HEAT”, and the plug from the
fan into the receptacle marked “VENT”(Figure 11).
