Read all instructions carefully before installing your HV
Serial Number _________ Date of Purchase __________Point of Purchase _________________
The serial number is located on the shipping carton and on a label affixed to the upper housing.
Unpacking your HV: When you have unpacked your HV carefully you will find the following:
The Best Location for your HV: The HV should be installed in your attic in a central location within your
home. Above a central hallway or at the top of a stairwell will provide the best airflow. The fan can be mounted vertically.
► 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 open into an unoccupied area.
► Make sure that you have adequate exhaust area out of your attic. This can be accomplished with a combination of roof,
ridge, soffit or gable end vents or other attic exhaust points. The HV1000 requires a minimum of 2 square feet and the
HV1600 requires 3.5 square feet of clear exhaust area. Allow 50% loss of clear area for louvers and screens
► Make sure that there is enough clearance above the fan for the doors to open. The minimum requirement for the HV
with R22 insulating doors is 11” and 12” is required for models with R38 insulating doors.

Installation
Tools and supplies needed
You will need two pieces of 2x stock to match your existing framing, a saw to cut the hole in the
ceiling, a hammer or screw gun to attach the blocking to the existing joists and a Phillips head
screw driver to attach the grille.

1. The fan housing will fit either 16” or 24” on center framing. Cut two pieces of 2x stock
(2 x 6 or 2 x 8 etc.) of the same dimension as the existing joists. Add these pieces of
framing to form a box between the joists. (Figure 1).
2. Cut a hole in the ceiling under where the HV will be installed. The hole should be no
larger than 14 1/2" x 22 1/2". This will allow for the grille to cover the exposed edges.
The suggested method for making the proper sized hole in the ceiling is; cut a pilot hole
under where the fan will be installed. (Figure 2) From above, using a saw, cut along the
inside edge of the framework removing the ceiling panel and any strapping within the
frame. Do not damage electrical wiring or other hidden utilities.
3. Install the foam gasket (supplied) on the top of the joists and added framing. Check
the joint between the ceiling and the 2x stock. Some types of ceilings are spaced away
from the joists. Any gap between the 2x’s and the ceiling should be sealed prior to final
installation. (Figure 3) Use a low expansion spray foam sealant (not supplied).
4. Set the HV on the gasket with the doors facing to open into the attic. The lower
housing will fit into the box with the mounting flanges overlapping the joists. (Figure 4)
The HV should not be forced into this opening. Forcing it into place may cause the
doors to bind and not function properly.
5. If desired, secure the HV to the top of the joists using the #8x3/4 screws provided.
When fastening the mounting flange to the joists care should be taken that all screws
are tightened evenly to avoid the door hinges binding.
6. Wire the HV as shown in the Wiring section of this manual. It is recommended that
the wiring of the HV be done by a licensed electrician.
7. Check the HV for proper operation. Turn the unit on and allow 30 seconds for the
doors to fully cycle open and the fans to start. DO NOT FORCE THE DOORS OPEN.
8. Install the grille (6 screws included) on the ceiling below the fan. (Figure 5)

Operating your HV
HV1000 - The HV1000 is operated by the wall switch installed per the wiring
instructions. An optional remote control kit is available (Part# TTi-HVRC).
HV1600 - The HV1600 is controlled by the hand held remote transmitter.
Additional controls, when used, may override the remote control. See the Wiring
section of this manual for further details.
IMPORTANT
Be sure at least one window is open when the fan is operating
Some owners find the installation has a more finished look when the inside of the blocking has been painted before
the unit is installed and the grille is put in place.
