1b. Internal Wire Compartment: If the motor is already installed in the housing, remove the
two screws holding the blower assembly in place. Lift up on the assembly and slide it
out of the tabs on the housing
(Figure 6)
. Remove the wire compartment cover screw
and place the cover in a secure place
(Figure 7).
NOTE:
If the fan motor plug is connected to the fan housing receptacle, unplug so the blower
assembly can be completely removed.
Standard and Motion Sensing Models
2a. Run wiring from an approved wall switch (not included) carrying the appropriate
rating. One neutral (white), one ground (green or bare copper), and one hot (black lead
connected to the switch). 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 receptacle.
2b. From where you have chosen to access the fan’s junction box, connect the white wire
from the house to the white wire from the fan’s receptacle. Connect the black wire
from the wall switch to the black wire from the fan’s receptacle. Connect the ground
wire from the house to the green wire from the fan housing
(Figure 8).
Use approved
methods for all connections.
NOTE:
The fan’s receptacle wires might need to be pulled outside compartment for connection.
Only pull the four loose wires outside of compartment. Additional wires will be present.
NOTE:
Unit must be grounded according to all local and national codes.

Humidity Sensing Models
3a. For proper operation the humidity sensing fan will require a 3 way switch (not included).
Run wiring between the fan and the switch location. Make sure you leave enough wiring
in each box to make the connections. At the switch box connect the black wire from the
house to the common terminal of the switch. Connect the black wire from the fan to one
of the switched terminals on the switch. This position will energize the automatic mode
and the fan will energize upon a rise in humidity. Connect the yellow wire from the fan
to the other switched terminal on the switch. This position will activate the Manual On
feature and energize the fan. Properly connect the ground and neutral (if applicable)
mount the switch and the cover.
3b. From where you have chosen to access the fan’s junction box, connect the white wire
from the house to the white wire from the fan. Connect the wire from the automatic
position on the wall switch to the black wire from the fan, connect the wire from the
manual On position on the switch to the yellow wire from the fan. Connect the ground
wire from the house to the green wire from the fan housing
(Figure 9).
Use approved
methods for all connections.
NOTE:
The yellow wire may contain a wire crimp nut which will have to be cut off and
the wire stripped.
4.
Carefully tuck wire back inside wire compartment and replace wire compartment cover
securing with the screw that was removed earlier.
SECTION 6
Completing the Installation
1.
Use a sealant appropriate for contact with the building materials present and for the
temperature requirements of the installation to prevent air leakage from unconditioned
spaces is recommended. If gaps between unit housing and ceiling are great, additional
material (backing rod, ceiling material) may be required.
NOTE:
This fan is rated for direct insulation contact (Type IC) and it is recommended that this fan
be completely covered by insulation in order to reduce heat loss or gain to unconditioned space.
2.
If the fan’s blower assembly was removed during the wiring process, reinstall the
blower by reversing the directions in
Section 5
(Wiring),
Step 1b.
3a.
STANDARD MODELS:
Plug the fan’s
quick connect motor cord into the
corresponding receptacle located on
the wire compartment cover. This cord
will only fit one way into the receptacle
(Figure 10).
3b.
HUMIDITY SENSING MODELS:
Plug the
fan’s quick connect motor cord into the
corresponding receptacle located on the
wire compartment cover. Connect the
two pin connector from the humidistat
compartment to the two pin connector
from the side of the wire compartment
cover. These cords will only fit one way
into the receptacles
(Figure 10).
3c.
MOTION SENSING MODELS:
Plug the fan’s quick connect motor cord into the
receptacle located on the side of the wire compartment cover. Plug the 4 pin quick
connect cord from the grill into the 4 pin receptacle located on the top of the wire
compartment cover. These cords will only fit one way into the receptacles
(Figure 10).
4.
Install the ceiling mounting flange to cover any gaps which exist between the housing
and the finished ceiling. Put sealant (not provided) on inside edge of the ceiling
mounting flange to ensure that the flange is sealed to the ceiling. Line up the screw
holes in the ceiling mounting flange with the screw holes on the inside of the housing
and press flange in place so it is tight against the ceiling. Reinstall ceiling flange
mounting screws inside the housing
