Waterproofing the aeroponic system “motor.” a The humidifier rounded plate is anchored to the base by two screws, one of which is visible (red arrow). Unscrewing these opens the humidifier. b Once the rounded plate is removed, the six holes that must be sealed (red arrowheads; two are behind the capacitor), the electric cord entry and another hole (red arrows) into the electric parts that must be sealed are visible. c The interior of the base is filled with silicone sealant. d After the metal plate is reattached to the base with its screws, the seam is sealed. e The entry point for electric power to enter the base is sealed. f The electric cord is sealed. g The opposite side of the base from the power entry site, where there is an opening is sealed. h The underside of the base. The hole in the black disk motor mount is visible (red arrow). i The underside of the base after sealing. The hole in the black disk motor mount is sealed (red arrow). A thin bead of sealant is applied between the black disk motor mount and the other parts of the base (red arrowheads). j Parts are reassembled onto the motor shaft in order: whirl disk (single arrowhead), guiding disk (double arrowheads) with the suction piece (double arrows) screwed onto the motor shaft firmly to hold the pieces in place. The three-piece atomizer ring parts (single arrow) should then be slotted into place on the bottom of the support disk
