Page 23: Duct Installation
3.8 Duct installation 3.8.1 General recommendations The connections for process and reactivation air are designed in accordance with the recommendations in ISO 13351. The rectangular duct connections contain tapped inserts for M8 screws. NOTE! The dehumidifier has been designed to operate at specific process airflows (corresponding to the fan sizes installed) and must not be directly connected to air-conditioning systems. -
Page 24: Duct For Outdoor Air Inlet
3.8.2 Duct for outdoor air inlet When bringing ambient air from outdoors into the dehumidifier, the inlet duct opening must be located sufficiently high above ground level to prevent dust and debris from entering. The ducting must be designed to prevent rain and snow from being drawn into the dehumidifier. The air inlet must be located away from possible contaminants such as engine exhaust gases, steam and harmful vapours. -

Page 50: Scrapping
Scrapping The unit must be scrapped in accordance with applicable legal requirements and regulations. Contact your local authorities. The rotor material is not combustible, and should be deposited like glass fibre materials. If the rotor has been exposed to chemicals that are dangerous to the environment the risk must be assessed. The chemicals can accumulate in the rotor material. -
