Setup and Installation

The EWF-180 is designed for through-the-wall installation, suitable for walls 4 to 9 inches thick. It vents directly to the outside, eliminating the need for extensive ductwork.

Tools and Materials Required:

• Drill
• Screwdriver (Phillips and Flathead)
• Measuring Tape
• Level
• Saw (for wall opening)
• Wire Strippers
• Electrical Tape
• Caulk or Sealant (weather-resistant)
• Appropriate electrical wiring (e.g., 14-gauge)

Installation Steps:

1. Choose Location: Select a wall location that allows for direct venting to the outside. Ensure there are no obstructions (e.g., studs, pipes, wiring) within the wall.
2. Prepare Wall Opening: Measure and mark an opening on the interior and exterior walls according to the fan housing dimensions (approximately 11-11/16 inches by 14-1/4 inches). Carefully cut the opening using an appropriate saw.
3. Install Housing: Insert the fan housing into the prepared wall opening. Ensure it is level and secure. Fasten the housing to the wall studs or framing using appropriate screws.
4. Electrical Wiring: Route electrical wiring from a GFCI-protected circuit to the fan's wiring compartment. Follow the wiring diagram provided on the fan's label and in the included safety sheet. Connect the power supply wires to the fan's wires (typically black to black, white to white, and green/bare to ground). Secure all connections with wire nuts and electrical tape.
5. Attach Motor Assembly: Secure the motor assembly within the housing according to the instructions.
6. Install Grill: Attach the white polymeric grill to the interior side of the fan housing. The grill measures 11-1/2 inches by 11-1/2 inches.
7. Seal Exterior: Apply weather-resistant caulk or sealant around the exterior edges of the fan housing where it meets the wall to prevent moisture intrusion.
8. Test Operation: Restore power at the service panel and test the fan's operation.

Operating Instructions

The Air King EWF-180 fan operates with a simple on/off mechanism, typically controlled by a wall switch (not included). When activated, the fan will draw air from the room and exhaust it directly to the outside.

• Activation: Turn on the wall switch connected to the fan to begin operation.
• Deactivation: Turn off the wall switch to stop the fan.
• Optimal Use: For best results in bathrooms, operate the fan during and after showering or bathing to effectively remove moisture and odors. For other rooms, use as needed to improve air circulation and remove stale air.

Maintenance

Regular maintenance ensures optimal performance and longevity of your exhaust fan. Always disconnect power before performing any maintenance.

• Grill Cleaning: Periodically remove the grill and wash it with mild soap and water. Rinse thoroughly and allow to dry completely before reattaching.
• Fan Blade Cleaning: With the power disconnected, carefully wipe the fan blades with a damp cloth to remove dust and debris. Do not bend the blades.
• Motor Lubrication: The motor is permanently lubricated and does not require additional oiling.
• Exterior Vent Cap: Periodically check the exterior vent cap for any obstructions (e.g., leaves, bird nests) and clear them to ensure unrestricted airflow. The spring-loaded aluminum back draft damper should move freely.
