The focusing optics must not be operated in an explosion
endangered environment.
If hot and humid air contacts the cold surfaces, condensate is
formed at certain temperatures.
To avoid the formation of water of condensation on the focusing
optics, the cooling water temperature must not be set to too
cold a value.
The required cooling water temperature is determined by meas-
uring the ambient temperature and humidity in the surroundings
of the focusing optics (see "Determining the necessary cooling
water temperature", pg. 2‐41). These measured values can be
used to read the temperature in the dew point diagram starting
from which the surrounding air will condense.
Note
The cooling water temperature must be at least 2 °C above the
indicated dew point temperature.
