SECTION 5
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. Using wiring carrying the appropriate rating, run a dedicated line on a 20 amp service
from the main service panel to an approved wall junction box (not included). Once inside
the junction box, split the hot (black) wire from the home and connect one end to each
of the switches into the terminal marked “COMMON TERMINAL”. Connect the ground
(green or bare copper) wire from the home to the junction box. The neutral (white) wire
from the home is not connected to the switch or junction box, but will be run to the
unit’s wire compartment. Use approved methods for all connections.
2. Run wiring from wall switches carrying the appropriate rating. One neutral (white), one
ground (green or bare copper), and four hot (black, red, blue, yellow 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.
3. Connect the white wire from the house to the four 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 main light control). Connect the fourth hot (yellow)
wire from the wall switch to the yellow wire from the fan (this is the night light control).
Connect the ground wire from the house to the green wire from the fan
(Figure 9)
. Use
approved methods for all connections.
