5. Installation

This section provides general guidelines for installing the Air King AK100D exhaust fan. Professional installation is recommended for electrical wiring and ductwork.

5.1 Pre-Installation Checks

• Ensure power is OFF at the circuit breaker before starting any electrical work.
• Verify the ceiling or wall opening size is appropriate (recommended 11 inches x 9.5 inches with at least 8 inches of clearance).
• Confirm all necessary tools and materials are available (e.g., screwdriver, wire nuts, duct tape, mounting hardware).

5.2 Mounting the Fan Housing

1. Position the fan housing into the prepared ceiling opening.
2. Extend the included mounting hanger bars to span between ceiling joists.
3. Securely fasten the hanger bars to the joists using appropriate fasteners. Ensure the fan housing is level and firmly supported.

5.3 Ducting Connection

1. Connect a 4-inch round duct to the fan's duct collar.
2. Secure the duct to the collar using duct tape or a clamp to ensure an airtight seal.
3. Route the ductwork to the exterior of the building, ensuring it is as straight and short as possible to maximize airflow.
4. Ensure the back damper is free to open and close, preventing backdrafts.

5.4 Electrical Wiring

1. Connect the fan's electrical wiring to the household wiring according to local electrical codes.
2. Ensure all connections are secure and properly insulated.
3. This fan is designed for 120-volt AC operation.
4. If installing over a tub or shower, the circuit must be GFCI protected.

5.5 Grill Installation

1. Once the fan housing is mounted and wired, attach the contoured grill to the fan housing.
2. Ensure the grill is flush with the ceiling for a clean, integrated appearance.

6. Operation

The Air King AK100D features dual-speed operation, allowing for flexible ventilation control.

6.1 Dual Speed Functionality

• Low Speed (50 CFM, 0.5 Sones): This setting is ideal for continuous whole-house ventilation, quietly maintaining air quality by removing stale air and moisture.
• High Speed (100 CFM, 1.5 Sones): Activate this setting for local exhaust when higher ventilation is needed, such as during or after showering, to quickly remove humidity and odors.

The fan's speed can be controlled via a compatible wall switch (not included) that supports dual-speed fan operation.

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your exhaust fan.

7.1 Cleaning the Grill

1. Turn off power to the fan at the circuit breaker.
2. Carefully remove the fan grill from the housing.
3. Wash the grill with mild soap and water. Rinse thoroughly and allow it to dry completely before reattaching.
4. Wipe down the visible parts of the fan housing with a damp cloth.

7.2 Cleaning the Fan Interior (Annual)

1. Turn off power to the fan at the circuit breaker.
2. Remove the grill.
3. Carefully detach the motor and blower assembly (refer to installation diagrams if needed).
4. Use a soft brush or vacuum cleaner with a brush attachment to remove dust and debris from the fan blades and motor housing. Do not use water directly on electrical components.
5. Reassemble the motor and blower, then reattach the grill.
6. Restore power to the fan.

Do not lubricate the motor; it is permanently lubricated.
