Conceal the Central Filtration Unit
1. Slide the central filtration unit—attached to the acoustic tube,
foot switch, and power supply—underneath your bed.
2. Adjust the flexible acoustic tube as necessary until all cords and
components, except the tower assembly, are beneath your bed.
! Note
To prevent restricted air flow, leave at least 6 inches of space
around the air-inlet grill on the central filtration unit.
The central filtration unit is designed to fit underneath a
standard-sized bed frame. If the unit does not fit beneath your
bed, we recommend you insert risers under each bed post. If
you are still unable to slide the unit under your bed, you may
position the unit on its side, on a level surface next to the bed.
