Fig. 26 to Fig. 27 show the installation of the side panels (affectionately called “wings”). These panels serve the purpose of hiding the ceiling mount structure and the lugs of the hoisting system (See Fig. 1).

Fig. 28 shows the 4 fans being wired to be connected to the LV system of the projector which is supplying energy to the original 80 mm fans. On the ECP there is a small RC circuit before each fan that should serve the purpose of reducing electrical noise. These circuits have been maintained by soldering the wires of the new fans directly onto the board of the RC circuit of each fan. These circuits have a socket which enables connections to the 4 plugs coming from the LV power supply system of the projector.

Fig. 29 shows 2 of the 4 fans seen from outside (notice the polyurethane insulating foam).
