4. Installation Instructions

This fan is designed for easy fit installation, often replacing common bath fan housing sizes without extensive drywall modification. However, careful attention to detail is required for proper mounting and wiring.

4.1 Tools Required

• Screwdriver (Phillips and Flathead)
• Drill
• Wire Strippers
• Pliers
• Measuring Tape
• Utility Knife
• Safety Glasses and Gloves

4.2 Mounting the Fan Housing

1. Turn off Power: Before starting, ensure power is OFF at the circuit breaker or fuse box to avoid electrical shock.
2. Prepare Opening: If replacing an existing fan, remove the old unit. The new housing may be smaller, requiring additional wood blocking between joists for secure mounting.
3. Position Housing: Place the fan housing between ceiling joists. The housing should be positioned so that its bottom edge is flush with the finished drywall surface, not the bottom of the joist. This is crucial for the LED light/cover to sit properly.
4. Secure Housing: The fan housing has pre-drilled mounting holes. Secure the housing to the joists using appropriate screws. It is recommended to add additional mounting screws on all sides for stability. Before drilling new holes, temporarily install the fan motor housing to identify locations where screws will not interfere with its installation.
5. Connect Duct Work: Attach the appropriate size duct (typically 4-inch round) to the fan's duct connector. Secure with duct tape or clamps to ensure an airtight seal. Ensure the duct work vents directly to the outdoors.

4.3 Electrical Wiring

CAUTION: All wiring must comply with local electrical codes. If you are unsure, consult a qualified electrician.

1. Access Wiring Compartment: Open the wiring compartment cover on the fan housing. Note that the wiring compartment is compact.
2. Route Wires: Route the electrical supply wires (typically black, white, and ground) into the wiring compartment through an appropriate knockout hole. Use a strain relief clamp to prevent wire chaffing.
3. Make Connections:
   • Connect the black (hot) wire from the power supply to the black fan wire.
   • Connect the white (neutral) wire from the power supply to the white fan wire.
   • Connect the bare copper (ground) wire from the power supply to the green or bare copper fan ground wire.
   • If connecting to separate switches for fan and light, ensure correct connections for each circuit. The fan may come with quick-connect fittings; if your wiring requires multiple incoming wires per connection, use appropriate wire nuts.
4. Secure Wiring: Carefully tuck all wires into the wiring compartment and secure the cover. Ensure no wires are pinched.

4.4 Installing Motor and Grille

1. Install Motor Assembly: Slide the motor and blower wheel assembly into the fan housing. Ensure it clicks securely into place or is fastened with provided screws.
2. Connect LED Light: Plug the LED light connector from the grille assembly into the receptacle on the fan motor assembly.
3. Attach Grille: Squeeze the mounting springs on the grille assembly and insert them into the slots in the fan housing. Push the grille firmly against the ceiling until it is flush.

5. Operating Instructions

Your Utilitech ventilation fan is designed for quiet and efficient operation, providing both air circulation and illumination.

• Fan Operation: Turn on the wall switch connected to the fan. The DC brushless motor may start slightly slower than traditional AC motors, but it will quickly reach its full 100 CFM capacity.
• LED Light Operation: Turn on the wall switch connected to the LED light. The integrated 13-watt LED light provides bright illumination. This light is dimmable; if you wish to adjust its brightness, ensure it is connected to a compatible dimmer switch (sold separately).
• Optimal Performance: For best ventilation, operate the fan during and after showering or bathing to effectively remove moisture and odors from the bathroom.

Regular maintenance ensures optimal performance and extends the life of your ventilation fan.

1. Power Disconnection: Always disconnect power at the service panel before performing any maintenance.
2. Grille Cleaning: Remove the LED light grille by gently pulling down on the sides to release the mounting springs. Wipe the grille with a soft, damp cloth. Do not use abrasive cleaners.
3. Fan Housing and Blower Cleaning: With the grille removed, carefully vacuum or wipe away any dust or debris from the fan housing interior and the blower wheel. Avoid bending or damaging the blower blades.
4. LED Light Module: The integrated LED light module is designed for long life (up to 30,000 hours) and is not user-replaceable. If the LED light fails or malfunctions, the entire unit may need to be replaced. Contact customer support for assistance.
5. Reassembly: Once clean, reattach the grille by squeezing the mounting springs and inserting them back into the housing slots. Restore power.
