Operating Instructions
The Merrimack II fan is operated via pull chains for fan speed and light control. It also features a reversible airflow switch for seasonal use.

Reversible Airflow Switch
The fan features a slide switch on the motor housing to change the direction of blade rotation, optimizing airflow for different seasons.
- Summer Mode: Set the switch to allow blades to rotate counter-clockwise, pushing air downwards to create a cooling effect. (Typically indicated by a "sun" icon).
- Winter Mode: Set the switch to allow blades to rotate clockwise, drawing air upwards to circulate warm air. (Typically indicated by a "snowflake" icon).
- Note: Ensure the fan is completely stopped before changing the direction switch.

- Cleaning: Use a soft brush or lint-free cloth to clean the fan blades and light kit. Do not use abrasive cleaners as they may scratch the finish or glass.
- Blade Balance: If the fan wobbles, check that all blade screws are tight. Minor wobbling is normal.
- Light Bulb Replacement: Replace LED bulbs as needed. Ensure power is off before replacing.
- Outdoor Use: For outdoor installations, periodically check for any signs of wear or corrosion due to weather exposure. The fan is water resistant, but not waterproof.
