Disassembly Notes

The housing disassembly requires a Torx T10 security bit. The housing is comprised of two metal pieces. The fan and a PCB containing two filter AC capacitors and a transformer are mounted to the L-shaped housing piece. A much larger PCB is mounted to the opposite housing piece. Wiring between the two pieces makes disassembly difficult. The fan must be removed from the housing and a several zip ties must be cut to fully separate the two pieces and gain full access to the PCBs.
