EXHAUST SYSTEM INSTALLATION
THE EXHAUST STACK of the X-90 console lamphouse is designed to fit a six inch (15.25cm)
diameter duct. This size ducting (rigid or flexible) must be used throughout the entire system and installed to
eliminate any possibility of downdraft or rain dripping into the lamphouse. The exhaust blower must be capable
of removing 300 cubic feet of air per minute (cfm) from the lamphouse.
A CIRCUIT (TB1-6 & 11) is wired to the X-90 distribution panel to allow interconnecting a
115 V.AC ceiling exhaust blower. This circuit is protected by the 10 ampere circuit breaker marked
LAMP
. An
advantage to wiring the external exhaust blower to the X-90 is that it can be energized simultaneously with the
other booth circuits through the
MASTER
contactor.
EXHAUST AIR FLOW is to be measured at the exhaust stack and not determined by the
rating of the blower. Static pressure caused by bends and long duct runs reduces actual air flow at the end of the
run. If more than one console is installed in a common projection booth, the exhaust air flow must be measured
at
each individual console.
EXCESSIVE EXHAUST DRAFT, such as 600 cfm or more, should be avoided. Excessive air
flow alters the overall cooling pattern of the xenon bulb. Should it be necessary to limit the air flow through the
exhaust system, install bypasses rather than dampers. See the illustration below.
IF THE CONSOLE is replacing a carbon arc lamphouse, make certain that the exhaust system
is thoroughly cleaned of all carbon ash or residue. Carbon ash, falling on a xenon bulb, will rapidly burn into
the quartz bulb envelope and possibly shorten bulb life.
