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
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.
