WARNING
It is important that you use extreme care in supporting
the indoor unit from the ceiling. Ensure that the ceiling is
strong enough to support the weight of the unit. Before
hanging the ceiling unit, test the strength of each attached
suspension bolt.
(5) Screw in the suspension bolts, allowing them to protrude
from the ceiling (Figs. 4-11 and 4-12).
The distance of each exposed bolt must be of equal length
within 50 mm. (Fig. 4-13)

The suspension method varies depending on whether
there is a suspended ceiling or not. (Figs. 4-14 and 4-15)
(7) Suspend the indoor unit as follows:
a) Install the bracket to the suspension bolt.
Stick it onto the ceiling surface. (Fig. 4-14~4-16)

N OT E
The ceiling surface is not always level. Confirm that the indoor
unit is evenly suspended. For the installation to be correct,
leave a clearance of about 10 mm between the ceiling panel
and the ceiling surface and fill the gap with an appropriate
insulation or filler material.
(8) If the tubing and wiring are to go towards the rear of the
unit, make holes in the wall. (Fig. 4-18)
(9) Measure the thickness of the wall from the inside to the
outside and cut PVC pipe at a slight angle to fit. Insert the
PVC pipe in the wall. (Fig. 4-19)
N OT E
The hole should be made at a slight downward slant to the
outside.

4-4. Duct for Fresh Air
There is a outside air intake duct connection port (cut-out hole)
at the left-rear of the indoor unit for drawing in fresh air. If it is
necessary to draw in fresh air, remove the cover by opening
the hole and connecting the duct to the indoor unit through the
connection port.
