Installation Guide

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 Models
2. Continuous Ventilation: For two speed fans wired for continuous ventilation, connect
the White wire of the fan to the White (Neutral) wire from the power source. Connect the
ground wire from the house to the green wire from the fan housing. Connect the Black
wire of the fan to the Black wire (Hot) from the power source. Using a properly grounded
standard duplex toggle switch (such as Leviton 5224-2W, not included) connect the Black
wire from the supply to one side of the top and bottom switch. Using a second properly
grounded standard duplex toggle switch, connect the Hot Yellow wire from the fan to the
input of the switch. Connect the second Yellow wire from the fan to the output side of the
switch. Closing the switch will change from normal to high speed (Figure 8).
NOTE: The yellow wire may contain a wire crimp nut which will have to be cut off and
the wire stripped.

3. For two speed fans wired for continuous ventilation, connect the White wire of the fan to
the White (Neutral) wire from the power source. Connect the ground wire from the house
to the green wire from the fan housing. Connect the Black wire of the fan to the Black
wire (Hot) from the power source. The fan will operate on low speed continuously and
boost to high speed when motion is detected. Using a properly grounded standard duplex
toggle switch (such as Leviton 5224-2W, not included) connect the black wire from the
supply to one side of the top and bottom switch. A manual override switch (not included)
can be used to provide a manual fan Off function (Figure 9).
NOTE: The yellow wire may contain a wire crimp nut which will have to be cut off and
the wire stripped.

4. For two speed fans wired for continuous ventilation, connect the White wire of the fan
to the White (Neutral) wire from the power source. Connect the ground wire from the
house to the Green wire from the fan housing. Connect the Black wire of the fan to the
Black wire (Hot) from the power source. The fan will operate on low speed continuously
and boost to high upon a rise in humidity. Using a properly grounded switch, connect 1
yellow wire to each side of the switch. Closing the switch will change from normal to
high speed. Using a properly grounded standard duplex toggle switch (such as Leviton
5224-2W, not included) connect the Black wire from the supply to one side of the top
and bottom switch. A manual override switch (not included) can be used to provide a
manual fan Off function (Figure 10).
NOTE: The yellow wire may contain a wire crimp nut which will have to be cut off and
the wire stripped.
5. Carefully tuck wire back inside wire compartment and replace wire compartment cover
securing with the screw that was removed earlier.
NOTE: The fan’s receptacle wires might need to be pulled outside compartment for connection.
Only pull the five loose wires outside of compartment. Additional wires will be present.
NOTE: Unit must be grounded according to all local and national codes.
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 AND HUMIDITY SENSING MODELS: Plug the fan’s 2 pin and 3 pin
quick connect motor cords into the corresponding receptacle located on the wire
compartment cover. These cords will only fit one way into the receptacles (Figure 11).
