EQUIPMENT DAMAGE
With a completely stopped fan and open control valve of the heater assembly
(pumped water, steam or refrigerant), temperatures inside the unit are roughly
equivalent to the supply temperature of the heating medium (normally around 90
°C). This can result in deformation damage to plastic parts (especially to plastic
droplet separators, surfaces of humidifier honeycombs etc.).
Besides, fans and motors with sealed bearings (re-lubrication is not required)
may sustain damage at temperatures above 80 °C. Consider a maximum oper-
ating temperature of 40° C for a number of electrical built-in components (fre-
quency inverters etc.) – see and observe relevant manufacturer's instructions!
