Safety Information

READ AND SAVE THESE INSTRUCTIONS

  1. WARNING — TO REDUCE THE RISK OF FIRE ELECTRIC SHOCK OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
    • Use this unit only in the manner intended by the manufacturer. If you have questions, contact the manufacturer.
    • Before servicing or cleaning unit, switch power off at service panel and lock the service disconnecting means to prevent power from being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag, to the service panel.
  2. This ventilation fan is approved for use over a bathtub or shower when installed in a GFCI protected circuit. Do not use unapproved fans over a bathtub or shower that is not approved for that application.
  3. 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.
  4. Always vent fans to the exterior and in compliance with local codes.
  5. Install ductwork in a straight line with minimal bends.
  6. Use 120 V, 60 Hz for the electrical supply and properly ground the unit. Follow all local safety and electrical codes.
  7. 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 motor humming noise.
  8. When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
  9. To reduce the risk of fire or electric shock, do not block air entry grill.
  10. Sufficient air is needed for proper combustion and exhausting of gases through the flute (chimney) of fuel burning equipment to prevent back drafting.
  11. Ducted fans must always be vented to the outdoors.
  12. Mount with the lowest moving parts at least 2.5 meters above floor or grade level.
  13. To reduce the risk of fire or electric shock, do not use this fan with any solid-state speed control device.

Follow the heating equipment manufacturer’s guideline and safety standards such as those published by the National Fire Protection Association (NFPA), and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.

  • WARNING Not suitable for use as a range hood.
  • CAUTION For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.
  • CAUTION Do not install in locations where the air temperature will exceed 104°F (40°C).
  • IMPORTANT Exercise care to not damage existing wiring when cutting or drilling into walls or ceilings.
  • NOTE Make sure duct work size is a minimum of the discharge. Do not reduce. Reducing the duct size can increase fan noise.
  • IMPORTANT You may want to consult with a professional electrician regarding the wiring of your ventilation fan.
  • WARNING To reduce the risk of electric shock, please disconnect the electrical supply circuit to the fan before installing light kit.
  • CAUTION This product must be properly grounded.

Pre-Installation

PLANNING FOR SUCCESSFUL INSTALLATION
When installing the ventilation fan in a new construction site, install the main body of the fan and duct work during the rough-in construction of the building. The grille should be installed after the finished ceiling is in place.
When installing in existing construction, use the dimensions on page 7 to determine the required hole size for the ceiling. Grille edges should overlap finished ceiling.

IMPORTANT The ducting from this fan to the outside of the building has a strong effect one the airflow, noise and energy use of the fan. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated airflow.

INSTALLATION OPTIONS
We recommend installing the ventilation fan by securing the main body of the fan against one ceiling joist and using the hanger bars as necessary for support of the adjoining joist. There are multiple installation configurations possible for this ventilation fan. Not all configurations are shown. If your installation requires a variation other than those shown, consult with a licensed contractor to determine the best installation for your project. If you are replacing an existing fan, ensure that the new grille will adequately cover the existing opening.

Installation – New Construction

CAUTION:

  1. Make sure power is switched off at service panel before installation.
  2. Do not install in cooking area.
  3. Choose the location of your fan to ensure the best air and sound performance. It is recommended that the length of ducting and the number of elbows be kept to a minimum, and that insulated hard ducting be used. Larger duct sizes will reduce noise and airflow restrictions.
  4. Fan must not be installed in a ceiling thermally insulated to a value greater than R40.
  • STEP 1
    Remove the junction box

    • Unplug the motor.
    • Remove the screw on top.
    • Take out the wiring panel.
  • STEP 2
    Mount housing to ceiling joist with brackets

  • STEP 3
    Attach the duct and conduit to the fan
    4 inch round exible duct is recommended. This type of duct can provide the best performance.

CAUTION: All ducting must comply with local and national building codes. Connect the duct to the fan’s duct collar. Secure in place with tape or screw clamp. Always duct the fan to the outside through a wall or roof cap.

  • STEP 4 Connect wiring
    • Make sure power is switched off at service panel before installation. All electrical connections must be made in accordance with local code, ordinances or national electric code.
    • If the electrical wires do not match the colors shown, you must determine what each house wire represents before connecting. You may need to consult an electrical contractor to determine safety.
    • Connect wires as shown on wiring diagrams on page 6.
    • Use wire nuts (not provided) to connect house cable to ventilating fan.
    • Reinstall wiring panel and secure with screw

Humidity Sensor Operation (Humidity Sensing Models Only)

The humidity sensing fan is equipped with a humidity sensor that can turn on the fan automatically when the humidity level in your bathroom rises above your setting point (40 ~ 80 RH % continuously adjustable).

CAUTION: Humidity tolerance is about ±10%. Long-time operation will influence the detecting precision as dust accumulates. The humidity switch may need to be adjusted.

Humidity sensing mode

  1. Pre-set a trigger point from 40 ~ 80 RH %.
  2. When you finish the wiring, the fan will be on the humidity sensing mode. The fan will automatically run when the humidity level in the room is above your setting point. If the humidity level drops below your setting point, the fan will stop automatically.

Full speed mode

  1. Flip the ON/OFF switch to the “ON” position.
  2. The fan will be set to the full speed mode. The fan will run continuously regardless of the humidity level.
  3. Flip the ON/OFF switch to the “OFF” position, the fan will be set back to the humidity sensing mode.

Use and Care

CAUTION: Make sure power is switched off at service panel before servicing the unit.

Cleaning the grille
Remove grille and use a mild detergent, such as dishwashing liquid, and dry with a soft cloth. Never use any abrasive pads or scouring powder. Completely dry grille before reinstalling. Refer to instructions on page 6 to reinstall grille.

Cleaning the fan assembly
Unplug the motor cord. Wipe all parts with a dry cloth or gently vacuum the fan. Never immerse electrical parts in water. Plug the motor cord back in and restore power.
