Connecting the exhaust air system
NOTE – exhaust air lamp cooling
It is highly recommended that the lamp cooling air be
connected to an exhaust air system. The instrument ex-
haust air system can overheat if the maximum length of
the exhaust air channel and the maximum permissible
number of two 90° bends is not observed. This may re
-
sult in the instrument exhaust system overheating. In
turn, this will cause the instrument safety equipment to
continuously interrupt the power supply to the instru-
ment. Please observe the specifications for the instru
-
ment exhaust air system in sect. 3.3.
CAUTION – harmful UV radiation!
If the instrument is not connected to an on-
site exhaust system, hazardous levels of
UV radiation may be emitted. UV radiation
can cause irritation to the retina and skin.
Only operate the instrument with a func-
tional exhaust air system installed.
