What are the installation clearances
The clearance zones for the installation and maintenance of the appliance are shown in the figure on page 16 of the manual. Established spaces are necessary to avoid barriers to airflow and allow for normal cleaning and maintenance. Make sure that there is sufficient space to allow the panels to be removed for routine and supplementary maintenance operations. Page 16 of the manual also specifies that safety distances between the units and other appliances or structures are scrupulously respected so that the air entering and leaving the fans is free to circulate.
