Disassembly

Full disassembly procedure is unknown, but the device is flash-able with partial disassembly, albeit a bit finicky.

• Remove top grille according to manual;
• Unscrew the 4 philips screws at the bottom;
• Remove the PM sensor;
• Put the device on its side and carefully pull the fan as much as possible, until the wires put pressure.

Through the PM sensor door you should have access (using tweezers) to plug in DuPont wires.
