NOTE:
If the fan motor plug is
connected to the fan housing
receptacle, unplug so the blower
assembly can be completely removed.
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. Run 2 wires from a
properly grounded wall switch (not included) to the fan. Connect the Black wire of the fan
to the Black wire (Hot) from the power source. 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 9)
.
2b.
Intermittent Ventilation:
For two speed fans wired for intermittent ventilation with a
standard duplex toggle switch (such as Leviton 5224-2W not included). Connect the
White wire of the fan to the White (Neutral) wire from the power source. Connect the
ground wire from the fan to the ground wire from the power source. Properly ground the
switches. Connect the black wire from the supply to one side of the top switch. Connect
the black wire from the fan to the other side of the top switch, Connect 1 yellow wire
from the fan to each side of the bottom switch. The top switch turns the fan On & Off, the
bottom switch changes speed between high and low
(Figure 10)
.
NOTE:
Unit must be grounded according to all local and national codes.
4. Reinstall both the wire compartment cover and the fan’s venturi by reversing the
instructions in Step 1b of Section 5 Wiring. Make sure all wires are contained within the
wire compartment.

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. Plug the fan’s quick connect motor cord into the receptacle located on the wire
compartment cover. The cord will only fit one way into the receptacle
(Figure 11).
3. Install the grill by squeezing the two ends of the springs together and installing them up
into the slots on the fan’s housing. Push the grill up into position
(Figure 12).
4. Restore power and test your installation.
SECTION 7
Setting the Humidistat
(Model AK100DH Only)
This fan may be equipped with a humidity sensor that automatically turns the fan on (or to
high speed on dual speed models) when humidity is above set point and off (or back to low
speed on dual speed models) when humidity is at or below set point. If the fan is operating
too long or not enough, first check to see the humidity sensor set point. In cases where the
ambient humidity level of the room rises higher than the preset level, the fan will turn on even
if the room is not occupied. This helps prevent conditions that lead to mold growth.
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE SERVICING THE UNIT.
1.
To set the desired humidity level of the room, remove the grill and locate the
dehumidistat dial located on the wire compartment cover.
2.
Set the dial to the relative humidity you want the fan to maintain usually between 50 &
80%. Moist climates will require higher settings than dry climates. When the humidity
level of the room is below this setting the fan will remain off (or low speed on dual speed
models). When the humidity level rises above this setting the fan will turn on (or to high
speed on dual speed models) and run until the humidity level falls below this setting.
3. Reinstall the grill and restore power.
SECTION 8
Use and Care
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE STARTING INSTALLATION.
1.
Cleaning the Grill:
Remove grill and use a mild detergent, such as dishwashing liquid,
and dry with a soft cloth. NEVER USE ANY ABRASIVE PADS OR SCOURING POWDERS.
Completely dry grill before reinstalling. Refer to instructions in
Section 6
Finishing the
Installation
, to reinstall grill.
2.
Cleaning the Fan Assembly:
Wipe all parts with a dry cloth or gently vacuum the fan.
NEVER IMMERSE ELECTRICAL PARTS IN WATER.
