3. PROJECTOR INSTALLATION AND
ASSEMBLY
3.1. UNPACKING THE PROJECTOR
Before opening box(es), carefully inspect outside of carton(s). If carton
has been damaged, notify shipper immediately; do not open carton
unless instructed to do so.
The CHRISTIE P35GPS projector may be shipped in more than one container. Each
P35GPS projector normally comes complete with the following items:
•dual aperture plate (shipped in place)
•framing lamp (installed)
•soundhead flywheel (not installed)
•soundhead assembly (factory-aligned)
•dual-lens turret
•drive motor assembly
•instruction manual.
The console and projector are shipped in a single carton, with special pockets containing
smaller items. The lens turret and soundhead flywheel are shipped separately.
To unpack:
1. Open carton(s).
2. Remove all protective material from framing lamp, soundhead assembly, and lens holder.
3. Remove protective material around side panel.
3.2. INSTALLATION
To install the projector, referto Figure3-1. The required materials and tools for installing
and assembling the P35GPS projector areoutlined in the Table in Figure3-2.
1. Loosen but do not remove nut on projector mounting stud (item 4 in Figure 3-1). Verify
that lock washer (item 5 in Figure 3-1) and flat washer (item 6 in Figure 3-1) are correctly
positioned on mounting stud. Flat washer should be nextto lock washer, followed by nut.

2. Insert lock washer (item 2 in Figure 3-1) and flat washer (item 3 in Figure 3-1) onto
second hex bolt (item 1 in Figure 3-1). Insert hex head bolt, with lock washer and flat
washer, into upper left opening of projector mount. Rotate hex head bolt four full turns.
3. Lift and mount projector to console or pedestal. Thread two remaining hex head bolts
with lock washer and flat washer. Insert into two bottom mounting holes on projector.
4. Level projector on lamphouse or pedestal.
5. Tighten nut on mounting stud using 9/16" wrench.
6. Tighten three hex head screws using same wrench.

3.3. ELECTRICAL CONNECTIONS
Before wiring the projector, refer toFigure 3-3 for the wiring interface diagram.Use
stranded wire. Strip and tin the wire prior to connection. Use crimp connectors on all sound
connections. For projectors equipped with an automatic turret, refer to Section 6.6.3.
3.3.1. SOLAR CELL WIRING
Solar cell wiring requires a shielded, four-conductor audio cable. (red – left (+), black – left
(-), green – right (+), white – right (-)). The best signal-to-noise ratio is achieved by
maintaining the same ground potential between the soundhead and the cinema processor.
Refer to the directions in the sound system instruction manual for proper connection of the
sound system.

Figure 3-3: Projector Wiring Diagram (50- and 60-Hz models)
3.3.2. A-C PROJECTOR WIRING
A-C wiring to the projector requires stranded, 14-gauge wire. Be sure to follow all local and
national electrical codes for A-C wiring. The terminal connection numbers in the table in
Figure 3-4 refer toterminals TB-1 inFigure 3-3.
