(d) Installation procedure
Use the bolts (M8 × 2) to secure the sus-
1)
pension hardware so that it is 90 mm be-
low the ceiling surface.
2) Use the band to tightly secure the flexible
duct (ø 150) to the air outlet chamber and
duct joint on the indoor unit itself so that
it will not come off and there will be es-
caping of air. Be sure to insulate this area
from the top with heat insulation in order
to prevent condensation.
3) Use pan-head screws to secure the air out-
let panel to the air outlet chamber. At this
time, make sure there are no gaps between
the air outlet chamber and the air outlet
panel.
Note (1) If the outer covering of the flexible duct breaks, it
can be repaired with tape or other such material.
Escaping air could cause condensation.
