What the HV whole house cooling fans do
The HV is used to assist the natural cooling process in the house. When the
outside temperature drops below the inside temperature, the cooler outside air
can be used to cool the house. The HV will pull the cooler air from the outside,
through the house, up into the attic and push the hot air outside. The HV is a fan
product and will not cool the house below the outside air temperature or create
a noticeable breeze. The HV can be used any time, for as long as needed, to
cool or change the air in the house.
The best location for your HV
The HV should be located as central as possible to the area that you want to
cool. Above a central hallway or at the top of a stairwell provide the best airflow.
The fan can also be mounted vertically, exhausting through a knee wall into an
HV1000
under-the-eaves attic space. Cooler outside air should be able to move through the window, the space that needs to be
cooled, and exhaust out through the fan into the attic.
Warning: Not to be used over cooking appliances.
Before installing your HV: Read all instructions carefully
► Some state and local electrical codes require fan products be installed by a licensed electrician. Check with your local
code officials before installation.
► Make sure that you have adequate net free exhaust area out of your attic. A minimum of 2 square feet is required for
the HV1000 and 3-1/2 square feet for the HV1600. This can be accomplished with a combination of roof, ridge, soffit or
gable end vents or other attic exhaust points.
► Make sure that there is enough clearance for the doors to open. Minimum requirement for the HV with R22 insulating
doors (HV1000 and HV1600-GR) is 11” and 12” for models with R38 insulating doors (HV1000-DB and HV1600-GDR).
► Make sure that there aren’t any pipes, wires, rafters, or air conditioning or heating ducts running through the space
where the HV will be installed and that the doors will face an unoccupied area.

Wiring
Important - Because of the motorized doors, wiring the HV is different than a normal ON/OFF fan. Please follow the
instructions carefully. Be sure to turn off power before wiring the HV Whole House Fan It is recommended that the
wiring of the HV be done by a licensed electrician.
The HV requires a constant source of power. Because the doors are motorized, they need power to open and power to
close. The fan operation is controlled internally.
HV1000
HV1600
There are three wires in the electrical box:
WHITE, RED, and BLACK.
The HV1600 is connected to power through the line cord
and must be plugged into a constant, grounded power
source. When connected to power, it will be fully functional
with the hand held remote control unit. When any of the
buttons on the remote control are pushed, the red indicator
light should momentarily flash.
• Connect the WHITE wire to Line Neutral
• Connect the RED wire to Line Hot
• Connect the BLACK wire to a Switched Hot Feed
When 115 VAC Hot is applied to it, the doors will
open. When 115 VAC Hot is removed, the doors will
close.
Optional Controls:
• Connect the ground wire to the screw in the electrical
box
Hardwiring the unit to wall switches using the BLUE and
YELLOW wires will provide additional, manual control. The
BLUE wire will provide on/off control and the YELLOW wire
will provide high or low speed control. Using a switch in the
ON position will override the remote control function.
Use only SPST (single pole, single throw) switches.

Care
All the motors in the HV are permanently sealed and do not require oiling. To keep dirt, dust and debris from the fans we
recommend that you periodically remove the grille from within the living space and dust the fan blades. Please remember
to make sure that the fan is OFF before dusting the fan blades.

Troubleshooting
HV1000: The most common problem with the HV1000 is caused by incorrect wiring. Before you check anything else make sure:
WHITE wire in HV1000 is connected to 115 VAC Line Neutral; RED wire in HV1000 is connected to 115 VAC Line Hot (Constant Hot
Feed); BLACK wire in HV1000 is connected to a switch that will make it hot when the switch is closed.
HV1600: If the wireless remote fails to activate the fan, the batteries may need replacing. The transmitter uses two type CR2016 3V
coin cell batteries. Remove the back plate from the transmitter and remove the batteries. Following the markings above the battery
holders, replace the batteries. Secure the back plate to the transmitter.
