WARNING:
To reduce the risk of electric shock, fire, or injury to persons, observe the following:
1. Use the device as per the manufacturer's guidelines. If you have any questions, get in touch with the manufacturer for help.
2. Before you clean or service the unit, ensure the power from the socket is switched off and lock the service panel disconnecting means.
3. A qualified technician should do all electrical wiring and installation work as per the stated standards and applicable codes, such as fire-rated construction codes.
4. Ensure enough air for proper combustion and exhausting of gas through the chimney to avoid back-drafting. Take note of the manufacturer's heating equipment safety standards and rules, National Fire Protection Association, and the American Society for Heating, Refrigeration and Air Conditioning Engineers, and local code authorities.
5. As you drill or cut into the ceiling or wall, avoid interfering with electrical wiring and other hidden components.
6. Ducted fans should be vented to the outside.
7. If you install this unit over a tub or shower, it must be marked as suitable and connected to a Ground Fault Circuit Interrupter (GFCI) protected branch circuit.
8. Do not place the switch at a point where it can be assessed from a shower or tub.
9. Do not use a dimmer switch to regulate the light of this device if you are using a fluorescent model.
10. This unit should be well-grounded.
CAUTION:
1. For general ventilation, avoid using the unit in exhausting explosive or hazardous materials and vapors.
2. This unit should only be used for ceiling installation up to a 12/12 pitch. Ductwork should point up. DO NOT FIX THIS UNIT IN A WALL.
3. Keep drywall spray, construction dust etc., off the power unit to avoid motor bearing damage and unbalanced and/or noisy impellers.
4. Read the description label on the unit for more information and requirements.
Install the Housing
For Existing Construction:
1. Select the installation for your fan in the ceiling. Use a minimum number of elbows and the shortest possible duct run for optimum performance.
2. In the attic, align the housing in the preferred location. Follow the outline of the housing on the ceiling.
3. Place the housing aside and drill the ceiling opening a bit larger than marked. Align the lower edge of the brackets a little higher than the bottom edge of the joists.
4. Position the housing in the opening. Align the mounting brackets with the joist and nail them through the keyhole on both ends. Tuck the bracket channels firmly around the mounting brackets to have a noise-free mount.
5. To rotate vertical housing position:
- Loosen adjustment screws on the housing.
- Move housing down or up until adjustment screws align with the mark showing you have finished the ceiling thickness. Tighten the screws firmly.
For New Construction:
1. Slip the adjustable fixing brackets into holes on the sides of the housing.
2. Select the installation for your fan in the ceiling. Use a minimum number of elbows and the shortest possible duct run for optimum performance.
3. Align mounting brackets with the joist. Put a mark on the keyhole slot on the mounting brackets.
4. Keep the housing aside and partially drive the nails into the joist.
5. Suspend housing from nails and fix the nails tight. Tuck the bracket channels firmly on the mounting brackets to realize a noise-free mount.
6. To rotate vertical housing position:
- Loosen adjustment screws on the housing.
- Move housing down or up until adjustment screws align with the mark showing you have finished the ceiling thickness. Tighten the screws firmly.
Installing the Ductwork
NOTE: The duct connector comes with a counterbalanced damper flap. The flap opens approximately 1" when the duct connector is connected to the housing. This design allows the insulation to have direct contact with fan/light housing per Underwriters Laboratories (UL) standards. The slightest backdraft can close the damper flat, blocking the air from entering the device or finished space.
1. Snap the duct/damper connector onto the housing. Ensure that tabs on the connector lock into slots in the housing. Fix a flush with the top of the housing at the top of the duct/damper connector.
NOTE: Ensure that the damper is well placed inside the duct connector. If not, squeeze the bottom and top of the connector to snap-flap back into its position.
2. Connect a 4" round duct to the duct/damper connector and extend it to the outside through a wall cap or roof. Confirm that the damper opens freely. Secure all duct connections using tape to make them safe and air tight.
Connecting the Wiring
Wire the device as per the diagram provided in the user manual. Connect the electrical as direct as possible to the device. Do not leave cables touching the sides or top of the device after the installation.
Connecting the Grille
1. Fix the light reflector into the front of the grille opening. Place the reflector/grille combination over the protruding screw and tighten using the provided acom nut. You can hand-tighten the acom nut to 1/4 turn.
2. Fix the light bulb. Insert one tab on the light lens into the grille/reflector combination slot. Insert the other tab carefully into the remaining slot.
Use and Care
Warning: Turn off the electrical power supply to the unit before servicing or cleaning the unit.
To Clean Grille and Lens:
Disconnect the light lens and the bulb. Remover the center nut of the reflector and lower the unit.
CAUTION: The reflector and grille are separate units. Detach the light from the WHITE receptacle. You can clean the plastic parts with mild, soapy water (using dishwashing liquid) and dry them with a soft cloth. Do not use steel wool pads, scouring powders, or abrasive cloth.
To Clean Fan Assembly:
Disconnect the fan assembly (BLACK receptacle). To disconnect the motor plate:
- Identify the single tab on the motor plate next to the receptacles.
- Push out on the side of the housing as you push up near the motor plate tab. Alternatively, you may insert a straight-blade screwdriver into the slot next to the tab and rotate the screwdriver.
- Carefully vacuum the fan, interior of the housing and the motor. DO NOT IMMERSE ELECTRICAL AND METAL PARTS IN WATER.
