(2) Part name to be removed or installed.
(3) Fig. No. showing procedure or part location.
(4) Identification of part to be removed, unhooked, unlocked,
released, unplugged, unclamped or unsoldered.
P= Spring, W= Washer, S= Screw, L= Locking tab, SD=
Solder, CN**(WR**)= Remove the wire (WR**) from the

• When connecting the flat wire to the connector, be careful with
the flat wire direction.
<Note 2b>
• When reattaching the Front panel assembly, make sure that
the door opener of the Side frame (R) is lowered in position pri-
or to the reinstallation.
• When reattaching the Front panel assembly, pay careful attention
