Installing and setting up
Learn how to position and install the projector.
Site requirements
To safely install and operate CP4445-RGB and CP4455-RGB projectors, the installation location must
meet these minimum requirements.
Physical operating environment
•
Ambient temperature (operating) 10 to 35°C (50 to 95°F )
•
Humidity (non-condensing) 10% to 80%
•
Operating altitude 0 to 3000 meters (0 to 9843 feet)
•
Site cleanliness: ISO Class 9 or cleaner
Projector exhaust ducting
Sufficient ventilation is required around the projector to regulate the temperature of the projector
electronics and optical components.
The projector has an 2.5 cm (8 inches) built-in exhaust duct. Exhaust HVAC ducts can be connected to
the projector to achieve optimal performance.
The installation site must provide an airflow 450 cubic feet per minute (CFM) at 1 to 1000 meters (3.3
to 3280.8 feet) elevation, and must accommodate a heat load of 4 kW.
For each additional 1000 meters (3280.8 feet) above sea level, increase the airflow (CFM) value by 15%.
If an extraction duct is not used, the operating temperature range is restricted to 10 to 25°C (50 to
77°F ) at a maximum altitude of 2000 meters (6561.7 feet).
Projector power connections
The projector requires two, 30A maximum rated, certified wall circuit breakers (one for each Main
Input). The wall circuit breakers must be part of the building and easily accessible.
The projector must be connected to power using hard-wired connections. The projector light source
requires the permanent AC connections to operate. A qualified electrician is required to connect the
projector to AC power.
There is also an available connector for an uninterruptible power supply (UPS) to provide backup
power for the projector electronics only. The UPS connection requires a 20A maximum rated circuit
breaker.
Chiller power connection
The chiller is connected to AC power through a power supply terminal located at the front of the chiller
unit.
