Page 33: Maintenance Of The Condair Rh-Vs Steam Humidification System
Maintenance of the Condair RH-VS steam humidification system The Condair RH-VS steam humidification system should be serviced once a year (e.g., prior to the humidification season). For this purpose the components of the Condair VS steam distribution unit must be disassembled and cleaned: Disassembling 1. Shut the Condair RH steam humidifier down (see Condair RH installation and operation manual) and, if necessary, wait until the components have cooled down sufficiently, so that there is no longer a risk of burns. -
Page 34: Maintenance Of The Condair Rh Steam Humidifier
After cleaning the components, reassemble the Condair VS steam distribution unit in reverse order of steps 3 to 13 and then put the ventilation system and the Condair RH back into operation. Important: When reassembling, make sure that the silencer components are correctly placed in the housing again and that the steam and condensate hose are correctly attached to the connections. -
