INSTALLING THE LFA 3.1 OR 4.1 ARM ON A WALL MOUNTING BRACKET

(continued)

MOUNTING THE LFA 3.1 OR 4.1 ARM TO THE WALL-MOUNTING BRACKET

(continued)

Position one 8” rubber band (Fig. 7, Item B) and the flexible hose supplied with the arm (Fig. 7, Item C) on the hood end of the arm (Fig. 7, Item A). Put the last rubber band on the hood connection. Mount the hood as shown in Figure 7.
