SAFETY INFORMATION

Please read and understand this entire manual before attempting to assemble, operate, or install the product.

• Follow all local safety and electrical codes as well as NEC (National Electrical Code) and OSHA (Occupational Safety and Health Administration).
• This unit must be properly grounded.
• Always disconnect the power supply prior to servicing the fan, motor, or junction box.
• Do not bend or kink the power wires. Protect from sharp edges, oil, grease, hot surfaces, chemicals, or other objects.
• Do not install where the room air temperature will exceed 40ºC (104ºF).
• Do not install over a tub or mount in a shower stall enclosure.
• Do not use it to exhaust hazardous or explosive vapors.
• Do not install in a cooking area.
• Do not install this fan vertically on a wall.
• Use this unit in the manner intended by the manufacturer. If you have any questions, please call the manufacturer (customer service number located on the last page).
• Installation work must be carried out by a qualified person(s) in accordance with all local and safety codes, including the rules for fire-rated construction. For use in non-fire rated installations only.
• Sufficient air supply is required for proper combustion and the exhaustion of gases through the chimney (flue) of fuel-burning equipment to prevent back-drafting. See the standards of NFPA (National Fire Protection Association) and ASHRAE (American Society for Heating, Refrigerating, and Air Conditioning Engineers) and the local building code authorities.
• Exercise care not to damage existing wiring when cutting or drilling into walls or ceilings.
• Fans should always be vented to the exterior and in compliance with local codes.
• Do not use this fan with any solid-state control device such as a dimmer switch. Solid-state controls may cause harmonic distortion, which can cause a humming noise.
• Prior to servicing or cleaning this unit, shut off the power supply at the panel and lock it to prevent the power from being turned on. If the panel cannot be locked, clearly mark the panel with a warning tag to prevent the power from being turned on.
• Do not install in a ceiling with insulation greater than R40. (This is required for installations in Canada only.)
• Ductwork should be installed in a straight line with minimal bends.
• Duct work size must be a minimum of the discharge and should not be reduced. Reducing the duct size can increase fan noise.
• This ventilating bath fan is intended for residential use only in 1-2 2-family dwellings.
• Never place a switch where it can be reached from a tub or shower.
• Make sure that the electric service supply voltage is AC 120 V, 60 Hz.
• Always disconnect the power source before working on or near the unit.
• This unit is designed and tested to be a supplemental heater for use with a timer or a switch. It is not intended to be used as the primary source of heat and is controlled by a thermostat.
• To avoid motor bearing damage and noisy and/or unbalanced impellers, keep drywall spray, construction dust, etc., off the power unit.
• Provide a separate 20-AMP circuit.
• This product is designed for ceiling installation only. Do not mount this product on a wall.
• Install in the ceiling only, at least 6 in. from any wall.
• For greatest efficiency, install heater so heat is directed toward tub or shower area. Avoid directing toward walls or windows.
• Do not install less than 8 ft. (2.4 m) from the floor.

PREPARATION

1. Inspect ductwork and wiring before proceeding with installation.
2. Before installation, provide inspection and future maintenance access at a location that will not interfere with installation work.
3. Remove the ceiling section using the dimensions provided below. Be careful to cut the hole exactly. If the hole is too big, the fan grille will not hide it.
4. Determine the distance between your joists.

Dimensions

WARNING:

Be careful to cut the hole exactly. If the hole is too big, the fan grille will not hide it.

ASSEMBLY INSTRUCTIONS

Unpacking

Carefully remove the unit from the carton. Remove the foam from the housing. Refer to the Package Contents list on page 3 to verify that all parts are present.

Installing the unit

Installing the fan body in an existing building requires an accessible area (attic or crawl space) above the planned installation location and existing duct and wiring.

CAUTION: Check the area above the installation location to ensure that:

• Duct work can be run, and the area is sufficient for proper ventilation.
• Wiring can be run to the planned location.
• No wiring or other obstructions can interfere with installation.

WARNING:

To reduce the risk of fire, do not store or use gasoline or other flammable vapors and liquids in the vicinity of the heater.

Mounting the fan between the joists

• Insert either the 12 in. suspension brackets (D) or the 14 in. suspension brackets (E) to the duct side and back of the fan body (C), depending on the distance between the joists.
• Insert the fan body (C) between joists. Make sure the fan body is level and perpendicular with the joist, and flush with ceiling surface.
• Allow for the thickness of the ceiling board used in your application. Do not flush mount to joist. Fan body (C) should be flush with the ceiling board.
• Secure the suspension brackets to joists with the long wood screws (CC).
• Secure the suspension brackets to fan body (C) with the short machine screws (AA).

Hardware Used

(AA) Short Machine Screws

(CC) Long Wood Screws

Connecting the duct

CAUTION: All ducting must comply with local and national building codes.

• Snap the damper/duct connector (not included) onto the fan body. Make sure that tabs on the connector lock into housing slots.
• Insert the duct into the duct connector and tape all duct work connections to make them secure and air-tight.
• Do not install the unit where ducts are configured as shown in Figure 2.
• Install the duct with a gradient of 1°~2° to the outside.

Completing the installation

• Insert the plug from the heating unit into the receptacle marked “Heat”, the plug from the fan into the receptacle marked “Vent”, and the plug from the light into the receptacle marked “Light”.
• Install the grille into the fan body using the medium machine screw.

WIRING INSTRUCTIONS

CAUTION

• Make sure the power is switched off at the service panel before starting the installation.
• All electrical connections must be made in accordance with local codes, ordinances, or the National Electrical Code. If you are unfamiliar with methods of installing electrical wiring, secure the services of a qualified electrician.

WARNING:

• This unit must be wired on a separate 20-amp circuit.
• If your house wires do not match these colors, you must determine what each house wire represents before connecting, and you may need to consult an electrical contractor to determine this safely.

1. Follow all local electrical and safety codes.
2. Never place a switch where it can be reached from a tub or shower.
3. Using wire nuts (not included), connect house power wires to fan wires.
4. 14 AWG (2.1 mm2) is the smallest conductor that shall be used for branch-circuit wiring. Each power wire (light, fan, heater) must have its own switch to operate independently.
5. For supply connections, use wire rated for at least 90ºC.

OPERATING INSTRUCTIONS

CAUTION: Failure to secure the reflector screws may result in a rattling or humming noise.

WARNING: This unit must be properly installed before it is used. Follow instructions for cleaning, user-maintenance, and operations recommended by the manufacturer, such as lubrication or non-lubrication. Any other servicing should be performed by an authorized service representative.

1. Turn on the light switch to turn on the light bulb.
2. Turn on the vent switch to operate the fan mode.
3. Turn on the heat switch to operate the heater mode.

CARE AND MAINTENANCE
