• Always unplug the fan before cleaning. Use the Allen key to loosen the safety screw on the front grille, rotate the grille to unlock it, and lift it off. Loosen the blade nut, lift the blade off the motor shaft, and rinse the blade, blade nut, and front grille by hand with mild detergent. Let all parts dry completely before reassembling. Wipe the exterior and rear grille with a soft, slightly damp cloth — do not immerse any other parts in water.

• Slide the blade back onto the motor shaft and tighten the blade nut. Align the front grille and rotate it until it locks, then tighten the safety screw with the Allen key. If the fan vibrates after reassembly, the blade nut maybe loose — tighten it and retest

The Allen key is also used to open the remote battery compartment, so keeping both together is a good idea. We recommend storing it in a consistent spot near the fan — a small drawer or in the remote box packaging. There is no built-in storage location for the Allen key on the device.

Check that you don't have an active schedule or timer set in the app — these can trigger the fan unexpectedly.

Firmware updates install automatically in the background when the fan is connected to Wi-Fi. You don't need to take any action — leave the fan powered on and connected to Wifi and it will update on its own. You can check the current firmware version in the app under device settings.

Try restarting your router and moving the fan closer to it temporarily. If it still won't connect, remove the fan from the app and re-add it. Make sure you're connecting to a 2.4 GHz network.
