Ceiling Unit; Screw; Truss Tapping Screw; Rotation Stop Screw - Panasonic TY-CE42PS20 Installation Instructions Manual

Fitting procedure
1. Checking the strength of the
installation location
 The ceiling-hanging bracket weighs approximately 16 kg
(35.3 lbs).
Refer to the instruction manual of the plasma display,
and check the weight of the plasma display unit which
will be fitted into the ceiling-hanging bracket.
 Refer to the outline drawing of the ceiling-hanging
bracket shown on the right, and check the ceiling
strength at the eight installation positions shown. If the
strength at any of these positions is lacking, provide
sufficient reinforcement.
2. Prepare the ceiling unit
 Remove the protective sheets (8 sheets) for the bracket
of the ceiling unit at four locations.
 Set a spring washer  on the rotation stop screw  ,
and fix at the position show on the right.
(Tightening torque: 1.5 to 1.8 N•m)
 Remove the two M8 assembly bolts from the ceiling unit
and separate the upper and lower sections of the unit.
• Use the removed M8 assembly bolts when attaching the
ceiling unit (lower section).
Note
• If using a 58-inch plasma display, adjust the attachment
brackets as shown in the figure.
 Remove the positioning screws (top and bottom), and
slide the positioning brackets and attachment brackets
as indicated by the arrows.
 Align the screw holes, and secure with the removed
screws.
(Adjust the opposite side in the same way.)
(Tightening torque: 1.5 to 2.0 N•m)
3. Install the ceiling unit (upper section)
 Before installing the upper section on the ceiling, pass
the wiring through the pipe as shown in the figure on the
right. Use an earthed extension cord for the power cord
(not supplied).
Pass the other device connection cables through the
same way.
 Make holes for inserting M12 bolts on the ceiling using
a method appropriate for the ceiling structure. Install
the upper section using a hex socket bolt (M12) (not
