(d) Installation procedure
Use the bolts (M8 × 2) to secure the
1)
suspension hardware so that it is 90 mm
below 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
escaping 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
outlet 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.
