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 that the chiller
communication cables are connected correctly between each projector-chiller pair. This ensures
that there is no cross-connection relative to the coolant lines.

Turning the projector on or off
Turn on the projector to display content, or turn off the projector to conserve energy or service the
projector.
To operate the projector, the circuit breakers must be in the ON position. If you are servicing the
projector or removing the protective covers, ensure that the MAIN and UPS circuit breakers are in the off
position.
In the right toolbar, select and hold Power.
If the light source is on when turning off the projector, the light source enters a ten-minute
cool-down period automatically.
