3.1. U
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)
•
•
•
•
• 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.
NPACKING 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.
framing lamp (installed)
soundhead flywheel (not installed)
soundhead assembly (factory-aligned)
dual-lens turret
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. I
To install the projector, refer to Figure 3-1. The required materials and tools for installing
and assembling the P35GPS projector are outlined in the Table in Figure 3-2.
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 next to lock washer, followed by nut.
P35GPS Projector 3-1
P35GPS Dual Lens Turret Projector
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.

LECTRICAL CONNECTIONS
Before wiring the projector, refer to Figure 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. S
OLAR 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.

3. Secure lens system with two locking screws.
Over-tightening can cause focus mechanism to bind.

ILM THREADING AND OPERATING PROCEDURE
Refer to Figure 4-1 for film threading and positioning.
1. Set Ultramittent to its rest position. There should be no sprocket movement when manual
turn-down knob (N) is turned.
2. Center framing knob (P) by aligning mark on knob with line on projector housing marked
CENTER FRAME
.
3. Swing out pad rollers (B, F, and L) on upper constant-speed sprocket assembly (A),
center constant-speed sprocket assembly (G), and lower constant-speed sprocket
assembly (M).
4. Swing out film shoe on Ultramittent assembly (E).
5. Pull out catch knob (D) and swing out trap and gate assembly (C).
6. Using slightly more film length than is required to reach film transport system, begin to
thread film into projector.
7. Align film on Ultramittent sprocket and close Ultramittent film shoe.
8. To form proper loop between Ultramittent and center constant-speed sprocket assembly:
a) Pull film loosely over pad roller while pad roller is in open position (R) and then onto
center constant-speed sprocket.
b) Mate film sprocket holes with sprocket roller pins.
c) Hold film in position and close pad roller.
The required film loop has now been formed.
9. Thread film on soundhead assembly as shown in Figure 4-1:
a) Holding two lateral guide rollers (H and K) towards each other, pull film tight and
align film on lower constant-speed sprocket assembly (M).
b) Tighten film on one sprocket hole so lateral guides barely float off sound drum.

10. Place film at upper part of Ultramittent in film guide (R).
11. Align film on steel bands of trap and gate assembly (T).
12. Close gate (C) and lock catch knob (D) in place.
13. Form 1.5-inch loop between upper constant-speed sprocket and gate (C), as shown in
Figure 4-1.
14. Align the film on upper constant-speed sprocket (A) and close film shoe (B).
15. To verify that film is correctly aligned on all sprocket rollers, move turn-down knob (N)
clockwise.
•••• Framing lamp can be turned “on” or “off” with black rocker switch
located on top of projector.
•••• Framing lamp is functional with picture changeover in either
position.
•••• If film reel is used, be sure take-up tension is in accordance with reel
manufacturer’s instructions.

5. MAINTENANCE
This projector has been designed to provide years of optimum performance while requiring
only routine maintenance and cleaning. However,
periodic maintenance program of scheduled operational checks and preventive maintenance.
CHRISTIE
strongly recommends a
5
5.1. G
Use the program outlined in the schedule in Figure 5-1 to maximize projector life and
operating efficiency. Procedures for these operations are described in the referenced sections
of this manual.
5.2. V
1. Visually inspect projector for signs of excessive dust, dirt, physical damage, frayed or
damaged cables, and loose hardware.
2. Remove, replace, and repair as necessary.
3. Visually inspect inner, outer, and shutter timing belts. Replace belts that are frayed or show
signs of wear.
4. Check belt deflection (Sections 6.4.1, 6.4.2, and 6.4.3) and re-adjust if necessary.

ISUAL INSPECTION
Ultramittent should be visually checked every 30 days. If leak is
detected, contact

LEANING
Projector should be kept clean at all times
.
1. Remove dust and foreign matter from projector and assemblies. Use soft, lint-free cloth, or
spray with compressed air at force no greater than 20 psi.
2. Using camel-hair brush or toothbrush, remove dust and foreign matter from pad rollers,
sprockets, Ultramittent shoe closure, and sound idler rollers, and from pads and shoes in trap
and gate assembly.
3. Using cotton-tip swabs, remove dirt and dust from soundhead optics.
4. Lightly oil lateral guide rollers and springs with very fine machine oil. Inner flange of lateral
guide should move easily and should spring back to rest position without sticking.
Do not adjust lateral guides without proper alignment tool (SK1994-3).

EMOVAL OF ASSEMBLIES
The following sections contain instructions and procedures necessary to remove assemblies
and components from the projector. Use only the specified tools to perform these
procedures. The use of any other tools will cause damage to the assemblies and components.
Appendix A contains a list of replaceable assemblies and components and their part numbers.
Removal and replacement of the assemblies discussed in Sections 5.4.1 through 5.4.13 may
be performed by the customer. The customer may also repair broken leads, solder
connections, and repair timing belts. All other repairs and replacements are to be performed
only by an authorized service representative. In general, any problem that does not appear to
be treatable by a minor procedure should be treated by removing the defective assembly and
returning it to
