a hand brush/brush. Follow the local regulations when cleaning. Do not clean the liquefier fins
in a clean room with items like a brush and do not use a vacuum cleaner without an extra-fine

Clean the liquefier fins using suitable cleaning appliances.
Make sure there is adequate ventilation (removal of waste heat, fresh air supply) for the tempera-
ture control unit, in case of air cooling, maintain wall clearance . → Page 20, section »Exemplary
illustrations of the cooling variants« and → Page 24, section »Ambient conditions« .
The liquefier fins must be cleaned (dust) from time to time as only then will the temperature con-
trol unit perform at its maximum cooling capacity.
