Please read and save these instructions. Read carefully before attempting to assemble, install, operate or maintain the equipment described within this manual. Carefully follow all safety information.
Getting Started
Tools/Materials Needed:
- Drill/drill bits
- Saw
- Level
- Screwdriver(s)
- 5/16” nut driver
- Construction screws
- Caulk or sealant
Inspection:
After unpacking your fan, carefully inspect for any damage that may have occurred during transit. Inspect for loose, missing or damaged parts. If there is physical damage to any parts of the fan, a freight claim must be filed with the carrier. Check to assure that all bolts, screws and set screws are securely tightened and have not become loose during transit. Retighten as required. Rotate propeller by hand to assure it turns freely.
General Safety Instructions
Warning: Before installing or servicing, always lock out and tag power source. Do not rely on a switch as the only means of disconnecting power. Failure to disconnect power can result in fire, electrical shock or serious injury. Motor will restart without warning after thermal protector trips. Do not touch an operating motor as it may be hot enough to cause injury. Do not place any body parts or objects in fan or drive components while fan is connected to a power source.
Caution:
- Read and follow all instructions, cautions, dangers and warnings. Failure to do so could result in personal injury, death or property damage.
- Make sure the electrical power source conforms to the requirement of the fan(s) as well as local codes.
- Electrical connections, installation and maintenance must be done by qualified electrical personnel in accordance with all applicable codes and ordinances.
- Unit must be adequately grounded.
- To reduce the risk of fire or electrical shock, do not expose this fan to water.
- Do not touch electrically live components.
- Free rotation of the propeller is critical. It must not touch any part of the venturi or framework.
- Assure that all power cords do not come in contact with any sharp edges, hot surfaces or chemicals. Immediately replace any damaged cords.
- Before operating your new fan, ensure propeller is torqued properly and all fasteners, screens and shutters are securely in place.
OSHA-compliant guards must be in place when fan is installed within 7ft of the floor or working level.

Fan Installation
- For framing dimensions, refer to rough-in opening height and width shown in the specifications above.
- Fan is designed to mount in wall with air discharging towards the outside. Center fan weight in opening.
- Position the fan in the wall with the discharge shutter facing to the outside of the building. Louvers hang down, closed completely.
- Ensure the fan is fastened securely in the opening to avoid excess “rattling” or vibration using proper fasteners. Fasteners not included.
- An aluminum or iron angle is recommended on sides/top/bottom of fan to attach fan to wall and help close rough-in gap around fan. Angle
- should attach to fan housing and wall opening frame to securely hold fan in place.
- Fan support bracing(wall brackets) should be used to properly support the portion of fan that hangs out of opening.
- Seal around fan to prevent air leakage.
- Refer to motor nameplate for wiring diagram.
