(FIG 2) 4.3 Separate the fan body (B) from the inner clamp plate (C). (FIG 3) 4.4 Separate the inner clamp plate (C) from the outer clamp plate (D). Note that the outer clamp plate is shown in the pictures without rear protective grille. It is NOT necessary to divide them. (FIG 4) 4.5 Place the outer clamp plate (D) and the rear grille in the hole made in the glass or partition from the rear and fix it in place using the tabs (E) to hold in place.
