MOUNTING THE LFA 3.1 OR 4.1 ARM TO THE
WALL-MOUNTING BRACKET
Leave the tape and plastic packaging on the extrac-
tion arm sections until the arm is completely installed
(including mounting the hood). The arm is spring-bal-
anced to compensate for the weight of the hood and
will spring out quickly if it is not mounted securely,
with the hood in place.
The rotating hinge of the arm comes in three pieces:
Metal rotating hinge, red plastic ring, and clamping
pin. Refer to Figure 3. Mount the red plastic ring to the
metal rotating hinge by fitting the clamping pin through
the hole in the rotating rod, and snapping it into place
on the U-shaped indents on the red plastic ring. The
lip of the ring should fit securely against the top edge
of the rotating flange, yet rotate with the rod. The
assembly should look like Part C in Figure 4.
Position the rotating hinge on the wall mounting brack-
et (See Fig. 4) so that the cable hole (Fig. 4A) is on
the wall side and the long side of the pin (Fig. 4B) is in
the front. Use the four 3” bolts with washers and nuts
to secure the rotating hinge.
