7.3 Humidity
• The device must not be operated in a condensing atmosphere. The humidity has to be considered in
order to prevent condensates within and outside the device.
• The temperature of the cooling water must not be lower than the dew point (see Tab. 7.1 on page14).
NOTICE
Damage/Destruction of the device due to condensing water
