5.2 Installation of the exhaust system
About Exhaust
The exhaust stack at the top side of the projector is designed to fi t a 201mm (7.91inch) diameter duct. This size must be used
throughout the entire system and installed to eliminate any possibility of downdraft or rain dripping into the lamp house.
C
AUTION
:
The exhaust system must be capable of removing minimum 4m
3
/min (140 CFM), measured at the
projector’s exhaust opening. Although not obligatory, Barco also advises to limit the amount of extraction to
a maximum of 5m
3 /min (180 CFM). Excessive air extraction can dramatically speed-up contamination of the
projector air inlet fi lters, hence requiring more regular fi lter cleaning interventions.
C
AUTION
:
The connection between the projector duct and the exhaust system should be done with a fl exible
connection piece. This to prevent that vibrations of the external exhaust system disturbs the projected image.
W
ARNING
:
The exhaust system must match the duct of the projector seamless. No gap may exist between
the connection of the duct and the exhaust system. This to prevent personal injury due to the UV light that
comes out of the duct of the projector.
Never look into the exhaust output on the top of the projector. High luminance and UV radiation could result in
damage to the eye. The installation of an exhaust system on top of the projector is mandatory before operating
the projector.
C
AUTION
:
If more than one projector is installed in a common projection booth, the above exhaust air fl ow
requirements are valid for EACH individual projector head exhaust stack. Note that inadequate air extraction
will result in decreased life expectancy of the projector as a whole as well as causing premature xenon lamp
failure.
W
ARNING
:
Temperature of exhaust air can approach 100°C.

To ensure maximum lamp life, operate the lamp house blower and the exhaust system for at least ten minutes
after extinguishing the lamp.
