Wiring
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT SERVICE PANEL BEFORE
STARTING INSTALLATION.
WARNING:
THIS UNIT MUST BE WIRED ON A SEPARATE 20 AMP CIRCUIT.
WARNING:
USE APPROPRIATELY SIZED COPPER CONDUCTORS ONLY RATED
FOR AT LEAST 75°C.
CAUTION:
ALL ELECTRICAL CONNECTIONS MUST BE MADE IN ACCORDANCE
WITH LOCAL CODES, ORDINANCES, OR NATIONAL ELECTRICAL CODE. IF YOU ARE
UNFAMILIAR WITH METHODS OF INSTALLING ELECTRICAL WIRING, SECURE THE
SERVICES OF A QUALIFIED ELECTRICIAN.
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 yellow 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.
3. Reinstall the wire compartment cover by sliding the tabs at the bottom of the cover into
the slots in the housing. Make sure all wires are tucked inside of the compartment and
are not being pinched or showing through. Reinstall the two screws removed in
