HV1600 Tamarack Whole House Fan 2 Speeds R38
Features Insulated Damper Doors
The HV1600 whole house fan made by Tamarack Technologies is a study in efficiency and a marvel in design. The HV1600 comes with insulated damper doors and is able to easily operate in two speeds---1150 and 1600 CFM. More powerful than the standard hv1000 whole house fan, the Tamarack 1600 keeps cold air out, which makes it ideal for use in cooler climates. And it is wired to continually deliver the proper amount of airflow needed to make living quarters more pleasant.

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, air conditioning or heating ducts running through the space where the fan 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 or gable end vents. The HV1000 requires a minimum of 3 square feet and the HV1600 requires a minimum of 5 square feet of attic exhaust area.
Make sure that there is a minimum of 1 foot of clearance above the whole house fan for the automatic doors to open (NEVER MANUALLY FORCE THE HV1600 DOORS OPEN). Another foot above the open doors will be needed to prevent a back pressure on the fans.
If your home has an engineered roofing system, care should be taken that the HV will fit within the truss layout.
HV1600 Operation: The fan is controlled by the hand held remote transmitter. Additional controls, when used, may override the remote control. See the Wiring section of the manual for further details.
The remote transmitter has 2 buttons. Button 1 is for ON/OFF. One press of button 1 and the HV-1600 will start.
A 2nd press of button 1 will stop the fan. Button 2 is for LO/HI speed. A press of button 2 will change the speed.
HV1600 Installation Instructions
Tools and supplies needed (Not Included): You will need the following items: 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, a Phillips head screw driver to attach the grille, weather strip material and low expansion spray foam sealant.
Important - Wiring the HV is different than a normal ON/OFF fan. The doors are motorized and need power to open and power to close. The HV requires a constant source of power. The fan operation is controlled internally. Please follow the instructions carefully. It is recommended that the wiring of the HV be done by a licensed electrician.
Be sure to turn off power before wiring the HV Whole House Fan
For the HV1000, a single pole, single throw (SPST)wall switch will be needed.
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.
TIP: When the HV is to be installed in a hallway or other location with low ceilings, some homeowners find that building a box out of 2 x 10s or similar material will raise the HV to a position where the sound level will be reduced but the efficiency of the fans will not be diminished. This box should not exceed 12 inches in height.
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 a foam weather stripping or other flexible material (not supplied) on the top of the joists and added framing. This gasket will serve to seal between the housing and the framing as well as dampen vibrations. 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. 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. 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. DO NOT OVER TIGHTEN.
6. Wire the HV as shown in the Wiring section of this manual. I t 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 INSULATED DOORS OPEN.
8. Install the grille (6 screws included) on the ceiling below the fan.
TIP: Some owners find the installation of the HV1600 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.

Question: I live in Phx, Arizona. I have electrican that is proposing to install on my roof, exposed to the outside, is that advisable? Wood truss roof with flaqt concrete tiles, 4:1 pitch. I read where these might be installed in attic, do you think this is ok exposed to outside. This is in an office, we are looking for roof vent fan. If not this spec, can you advise on other?
Answer: The HV fans are designed to be installed in the attic and vent thru existing attic vents. The do not install in the roof. There are whole house fan models that vent through the roof in cases where there is no attic space etc. Please call us to speak to an expert.
