(3) Open the installation hole. (Pre-set ceilings)
• Once the installation hole is opened in the ceiling where
the unit is to be installed, pass refrigerant piping, drain
piping, transmission wiring, and remote controller wiring
(It is not necessary if using a wireless remote controller)
to the unit’s piping and wiring holes.
See “
6. REFRIGERANT PIPING WORK ”, “ 7. DRAIN
PIPING WORK ”, and “ 10. WIRING EXAMPLE ”.
• After opening the ceiling hole, make sure ceiling is level if
needed. It might be necessary to reinforce the ceiling
frame to prevent shaking.
Consult an architect or carpenter for details.
(4) Install the suspension bolts.
(Use W3/8 to M10 suspension bolts.)
Use a hole-in-anchor for existing ceilings, and a sunken
insert, sunken anchor or other part to be procured in the
field to reinforce the ceiling to bearing the weight of the unit
for new ceiling.
(Refer to Fig. 3)
(5) For bottom intake, replace the chamber lid in the pro-
cedure listed in Fig. 4.
(1) Remove the protection net and the chamber lid.
(2) Refer to Fig. 4 for direction of the protection net and the
chamber lid.

the diagram.
The four holes which cannot be covered by the air filter
should be covered with commercially available tape.
5. INDOOR UNIT INSTALLATION
〈〈
As for the parts to be used for installation work, be sure to
use the provided accessories and specified parts desig-
nated by our company.
〉〉
(1) Install the indoor unit temporarily.
• Attach the hanger bracket to the suspension bolt. Be sure
to fix it securely by using a nut and washer from the upper
and lower sides of the hanger bracket.
(Refer to Fig. 5)
[ PRECAUTION ]
Since the unit uses a plastic drain pan, prevent welding
spatter and other foreign substances from the air outlet
during installation.
(2) Adjust the height of the unit.
(3) Check if the unit is horizontally level.
CAUTION
• Make sure the unit is installed level using a level or a plas-
tic tube filled with water.
In using a plastic tube instead of
a level, adjust the top surface of the unit to the surface of
the water at both ends of the plastic tube and adjust the
unit horizontally.
(One thing to watch out for in particular
is if the unit is installed so that the slope is not in the
direction of the drain piping, this might cause leaking.)
Note: All the above parts are field supplied.
