System operation for CP4445-RGB and CP4455-
RGB projectors
Understand the correct sequence for powering up and operating CP4445-RGB and CP4455-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.
