6.8 Connecting the exhaust air system
NOTE – exhaust air lamp cooling
It is highly recommended that the lamp cooling air be con
-
nected to an exhaust air system. The instrument exhaust
air system can overheat if the maximum length of the ex-
haust air channel and the maximum permissible number
of two 90° bends is not observed. This may result in the
instrument exhaust system overheating. In turn, this will
cause the instrument safety equipment to continuously
interrupt the power supply to the instrument. Please ob
-
serve the specifications for the instrument exhaust air
system in sect. 3.3.
CAUTION – harmful UV radiation!
If the instrument is not connected to an on-site ex-
haust 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
functional exhaust air system installed.
Connecting exhaust air system Xenotest 220/220+
(fig. 32)
1. Place the adapter
1
of the customer’s exhaust air sys-
tem on the connection nozzle
2
on Xenotest 220/220+.
The connection nozzle has a diameter of 100 mm.
2. Check whether the exhaust air system has an open
output outdoors or the on-site technical ventilation
system is ready for operation.
