Maintaining the chiller

For detailed information on maintaining the chiller equipment, refer to the product documentation
provided by the chiller manufacturer.
To identify any leaks or problems, perform regular visual inspections of the chiller equipment and
connections to the projector.
Follow the recommended coolant replacement and preventative maintenance schedules. For more
information, contact Christie technical support.
Dispose of coolant in accordance with local regulations.
System operation for CP4440-RGB and CP4450-
RGB projectors
Understand the correct sequence for powering up and operating CP4440-RGB and CP4450-RGB
systems.
The connected chiller must always be turned on first and turned off only after the projector is turned
off.
The system is ready to operate when the following steps are completed:
1. The connected chiller unit is powered on.
2. The projector's main power switches are on.
3. Communication between the projector and the connected chiller is confirmed and coolant
temperatures are correctly maintained.
If a thermal shutdown occurs in a dual projector installation, verify the chiller communication
cables are connected correctly between each projector-chiller pair. This makes sure no cross-
connection exists relative to the coolant lines.

If servicing the projector or removing the protective covers, make sure the MAIN and UPS
circuit breakers are in the OFF position.

If the light source is on when turning off the projector, the light source automatically enters a
ten-minute cool-down period.
