5. Mounting the Indoor Unit
• Hoist the indoor unit but do not apply any force against the condensate pan (the air outlet portions
and the condensate pan portion). If there is insufficient access for a hoist, the work must be
performed manually by two skilled installers.
• Suspend the unit by handling the suspension
brackets at all four corners of the unit. Do
not apply any pressure onto the polystyrene
condensate pan or pan outlets during the
installation process.
• Insert the suspension bolts into the notches of
the suspension brackets to capture the unit.
Secure the unit using nuts and washers. Then
check that the washers serve as stoppers at the
rising parts of the suspension brackets.
NOTE:
After securing the unit, piping and electric power
needs to be installed inside the ceiling area
adjacent to the unit. If a false ceiling is already in
place, determine the proper pathway for piping
and electrical lines before the unit is installed.
6. Spatial adjustments to accommodate the unit into a false ceiling:
• Adjust the position of the unit, as shown at right
and maintain the mounting position of the unit
in accordance with Items 2. and 3. on the previous pages

• The pattern board (template) for the installation and
the checking scale are printed on the packing.
Cut off the checking scale for dimension of opening from
packing to adjust the position of the indoor unit.
a. False-ceiling applications: Detach the
printed scale from the pattern board
(template). Raise the unit into position
and use this scale for clearance
adjustments between the unit and the
edge of the opening.
b. False-ceiling applications (without
opening): Use the outer edge of the
pattern board (template) to cut an
opening in the false ceiling. Raise the
unit into position and use this scale to
make minute clearance adjustments
as described in Item a.
c. Incomplete false-ceiling applications
(panels not in place): Secure the
pattern board (template) to the unit
with the four M6 screws provided and
raise as shown into position. Make
minute clearance adjustments as
ceiling panels are installed.
