Removing The Coolant Reservoir; Removing The Pump Module - Christie Cinema 4K-RGB CP4315-RGB Service Manual

Removing the coolant reservoir

Before replacing or refilling the coolant, the coolant reservoir must be removed from the projector
chassis.
1. Remove the electronics-side cover (on page 41).
2. Locate the coolant reservoir below the communications panel and loosen the two captive
screws (3 mm) at the base of the reservoir.
3. Tilt the reservoir slightly to unhook the rear tabs out of the plate and pull the unit partially out
of the projector.
4. Disconnect the two quick disconnect hoses.
5. Once disconnected, remove the reservoir unit from the projector chassis and set it aside on a
separate surface.
6. To replace the coolant reservoir, follow these steps in reverse order.
Ensure screws are torqued to 15 in-lb.

2. Remove the rear cover (on page 40).
3. Remove the radiator.
4. Remove the radiator intake fan pack (on page 59).
5. Disconnect the pump module coolant lines from both the LOS and light engine manifold plate.
6. If necessary, remove the one or two of metal retaining clips and release the coolant lines for
the pump module, which run along the bottom, intake-side of the projector.
7. From the front of the projector, unclip the coolant lines along the bottom under the lens
mount.
8. Pull the coolant lines through the baseplate opening and leave them hanging out the front of
the projector.
