5.2.3 Water Cooling Installation
The maximum operating temperature of a scintillation counter is 50°C. A cooling
system (which is available as extra) must be used if the temperature at the detector is
likely to be higher, due to heat emission of the pipeline and/or higher ambient tempera-
tures.
The cooling jacket can be installed later on the detectors. First, remove the lead shielding
at the front as well as the distance ring. After sliding over the cooling jacket, screw the
lead shielding on again without distance ring.
Water must enter from below and exit at the top. Thus, the cooling jacket is always
filled with water, ensuring good thermal insulation.

If higher ambient temperatures occur, the connection cables used have to be able to
withstand these temperatures!
