HV Series Whole House Cooling Fans Product Manual PLEASE LEAVE WITH HOMEOWNER! Coolers push hot air out of the attic while drawing cooler, fresh air into your home through open windows and doors. When the system is not operating, the motorized, insulated doors automatically close and seal, preventing drafts and heat or air conditioning loss. What’s the difference between the different HV models? Physically all Remember that a fan cools by using the temperature difference. It can never get cooler than the outside air. HV products are the same size and look just about the same. The HV 1000 series has silver faced insulation and the HV 1600 Gold R has gold faced insulation. Operationally, the HV 1000 moves 1000 cfm (cubic feet of air per minute) and the HV 1600 Gold R is a two speed version that moves 1600 cfm on high speed, just under 1000 cfm on low speed. Where should you locate your HV series fan? Air will always take the path of least resistance. The HV should be located so that it is as central as possible to the area that you want to cool. The cooler outside air should be able to move through the window, the space that needs to be cooled, and exhausted out through the fan into the attic. The attic must have the equivalent of 2 square feet of opening for the HV 1000 and 3.5 square feet for the HV 1600 Gold R to the outside. This can be a combination of ridge vents, gable, end vents or other attic exhaust points. The fan can even be mounted vertically, exhausting through a “knee wall” into an under-the-eaves attic space. What’s in the box? If you have unpacked your HV carefully and found these instructions, you should have noticed the grille wrapped in plastic including (6) white screws, the foam tape, the metal electrical box cover, a package of (7) screws and these instructions. The HV1600 Gold R also has a remote control unit as does the remote versions of the HV1000. If you have ordered a special control - timer, thermostat, or humidistat-that will also be in the box. DON’T PULL ON THE DOORS! You will strip the gears. Tamarack Technologies, Inc. What the HV Series of whole house cooling fans does: The HV Whole House Do Not Pull On, Carry By, or Stress the Doors! Keep this area clear a minimum of 11.25 inches. Installation: Before you start: Before you start installing the fan, you should be sure that there is enough room for the doors to open and there aren’t any pipes, wires, or air conditioning or heating ducts running through the space where the HV will be installed. Oh, and also - READ THESE INSTRUCTIONS. FIGURE 1 FIGURE 2 FIGURE 3 FIGURE 4 FIGURE 5 Tools needed: A saw to cut the hole in the ceiling. A saw to cut two pieces of 2x stock blocking. A hammer or screw gun to attach the blocking to the existing rafters. A screw driver to attach the grille and for the electrical work. Sometimes owners find the installation looks more finished if the inside of the blocking has been painted before the grille is put in place. 1. There are several methods for making the proper sized hole in the ceiling. The dimensions of the hole should be no greater than 23 1/2" x 14". • One way is to cut a pilot hole approximately in the center of where the fan will be installed. Then cut toward the edge to find the rafter pattern. Then lay out the fan opening on the ceiling. (Figure 1) • Another way is to mark the four corners of the opening from the attic side. Draw a line between each of the four corners to mark the fan rectangle. • A third way is to use a Stud Finder to locate the rafters, cut a template from the fan packaging material, and use the template to mark the opening on the ceiling. 2. With the hole cut out, add two pieces of framing to form a “box” between the rafters. These will probably be cut from “2x” stock (2 x 6 or 2 x 8 or 2 x 10, etc.) of the same dimension as the existing rafters. (Figure 2) 3. Install the foam gasket (supplied) on the top of the rafters and added framing. Check the joint between the ceiling and the 2x stock. Some types of ceilings are spaced away from the rafters. Any gap between the 2x’s and the ceiling should be sealed prior to final installation. (Figure 3) (Note: foam sealant not supplied.) 4. Set the HV whole house fan onto the top of the gasket. The lower housing will fit into the “box” with the mounting flanges overlapping the framing. NOTE: The HV should not be forced into this opening. It should slip easily down onto the top of the rafters. Forcing it into place may cause the doors not to function properly. (Figure 4) 5. If desired, secure the HV to the top of the rafters using the screws provided. (Note that there is virtually no vibration and no way for the HV to move out of the opening so there is little need to screw it into place unless your code requires it.) 6. Wire the unit as shown in the wiring diagram. We encourage the use of a licensed electrician. 7. Install the grille (screws included) on the ceiling below the fan. (Figure 5) 8. After wiring, check the HV for proper operation. Turn the unit on and wait 30 seconds for the doors to fully open and the fans to start. Wiring IMPORTANT - Because of the motorized damper doors, wiring the HV is different than a normal ON/OFF fan. Please follow the instructions carefully. Please use the correct wiring diagram for the HV product purchased. BE SURE TO TURN OFF POWER BEFORE WIRING THE HV WHOLE HOUSE FANS If you are not familiar or comfortable working with wiring, refer the installation to a licensed electrician. Some State and Local electrical codes require fan products be installed by a licensed electrician. Check with your local code officials before installation. Please use the supplementary instructions for wiring the HV 1600 Gold R. Call 1-800-222-5932 if these directions are missing. HV 1000 The HV 1000 requires a constant source of power. Because the doors are motorized, they need power to open and power to close. (Fan operation is controlled internally.) There are three wires in the electrical box: WHITE, BLACK, and RED. • The WHITE should be connected Line Neutral, 115 VAC 60 Hz • The RED should be connected to Line Hot, 115 VAC 60Hz. (This is constantly HOT.) • The BLACK is the switched lead. When 115 VAC Hot is applied to it, the dampers will open. When 115 VAC Hot is removed from, the dampers will close. • Connect ground wire to screw in electrical box HV 1000 HV 1000 HV 1000R The HV 1000R requires a constant source of power. Because the doors are motorized, they need power to open and power to close. (Fan operation is controlled internally.) There are four wires in the electrical box: WHITE, BLACK, and two YELLOWS that are capped off. • The WHITE should be connected Line Neutral, 115 VAC 60 Hz • The BLACK should be connected to Line Hot, 115 VAC 60 Hz. • Connect ground wire to screw in electrical box. The two yellow leads may be used to connect to a wall mounted, mechanical switch, timer, or thermostat. Call 800-222-5932 if you have wiring questions. The HV 1000R includes a wireless, wall mounted remote switch with a “Decora” style cover plate. This switch will act like a permanently mounted remote control and does not need to be wired and should be mounted no more than 20 feet from the fan. This switch should only be wall mounted. Please refer to the additional remote control instruction sheet for switch installation and battery replacement instructions. These batteries may need to be replaced on an annual basis.

When the outside IMPORTANT: temperature drops below the inside temperature, that cooler air can be used to cool the Be sure to open at least house. The HV should not be used to “cool” the house when it is hotter outside than it is inside. The HV is a fan product and can never cool the house below the outside or source one window when the air temperature. HV whole house fan is Open the windows and/or doors as you would normally. Turn the HV on until the operating. temperature in the house drops to the desired level. Natural cooling is a slow process. It may take a few hours or all night to thoroughly cool the house down. The HV can be used any time you want to change the air in the house, but be careful not to steal the air from combustion appliances that may back draft. Maintenance: Very little maintenance is required. All the motors are permanently sealed and don’t require oiling. Keep the dirt off the doors and the fans with occasional cleaning, and clear the dust off the intake grille. Troubleshooting The most common problem with the HV1000 is caused by mis-wiring so before you check anything else make sure: WHITE wire in HV 1000 is connected to 115 VAC Line Neutral (white); RED wire in HV 1000 is connected to 115 VAC Line Hot (Constant Hot Feed); BLACK wire in HV 1000 is connected to a switch that will make it hot when the switch is closed. Switch Doors Fans Possible Cause Try On Don’t Open Don’t Run No power Check connections or circuit breakers On (Audible “click”) Don’t Open Don’t Run No constant power on RED Check wiring connections.

Remove the face from the backing plate and locate the holders for the 3V button cell batteries. Observing the polarity (plus side should face the room), replace the batteries and the cover. Refer to additional sheet for complete details. If a secondary wall mounted, mechanical switch, timer or thermostat has been connected, this mechanical control will override the remote controls. If the mechanical control has turned on the fan, the remote control switches will not turn it off until the mechanical control has turned off.
