Location - Installation Notes
Install the unit in a heated space that provides clearance for service access. A typical location is in
either a mechanical room or an area close to the outside wall within close proximity to where the
weatherhoods are mounted. If a basement area is inconvenient or non-existent, install the unit in a
utility room or laundry room.
Attic installations are not recommended due to
 The complexity of work to install
 Freezing conditions in the attic
 Difficulty of access for servicing and cleaning
If attic installation is necessary the unit must be situated in a conditioned space.
Leave sufficient clearance at the front of the access door for servicing the air filters and core. The
recommended clearance is a minimum of 25 in (635 mm) for opening and closing the door. Airia
provides four straps for hanging the unit from the basement floor joists.
