Make sure the power is turned off completely.
2. Place a towel on this part of the machine. This is where we will place the RF Tube during the unloading process. Not only facilitates disassembly, but also helps protect the case and RF tube.
3. Remove the four screws from the beam expander, take them off and set the beam expander aside.
4. Remove the eight screws from the RF Tube bracket.
5. Place the RF Tube on the towel on top of the machine.

Process to Install:
1. Place the old tube aside and then place the new tube on the towel.
2. Re-install the 48V neutral and live（red and black）wires, fan wire connection and the Ethernet Cable.
3. Bolt on the beam expander. Unscrew the lens piece (Counter-clockwise).

4. Attach the tube to the bracket and lock it in place with the 8 screws.
