PREPARATION BEFORE INSTALLATION
• Relation of ceiling opening to unit and suspension
bolt position.
MAKE THE CEILING OPENING NEEDED FOR
INSTALLATION WHERE APPLICABLE.
(FOR EXISTING CEILINGS).
• Create the ceiling opening required for installation.
From the side of the opening to the casing outlet,
install the refrigerant and drain piping and
wiring for remote control. Refer to each piping or
wiring section.
• After making an opening in the ceiling, it may
be necessary to reinforce ceiling beams to keep
the ceiling level and to prevent it from vibrating.
Consult the builder for details.
INSTALL THE INSTALLATION HOOKS.
(USE EITHER A M8 OR M10 SIZE BOLTS).
Use expansible hooks, sunken anchors or other field
supplied parts to reinforce the ceiling in order to
bear the weight of the unit. Adjust clearance from
the ceiling before proceeding further (See figure
below).
1 Installation hook pitch dimensions.
2 Indoor unit dimensions.
3 Decoration panel dimensions.
4 Refrigerant piping.
5 (4) Installation hook.
6 Ceiling opening dimensions.
7 Hanger bracket.
8 False ceiling.
ADJUST THE POSITION TO ENSURE THE
GAPS BETWEEN THE INDOOR UNIT AND
THE FOUR SIDES OF FALSE CEILING ARE
EVEN. THE INDOOR UNIT'S LOWER PART
SHOULD SINK INTO THE FALSE CEILING
FOR 24MM/0.9".

NOTE:
Installation is possible with a ceiling dimension
of 600mm/23.6" (marked with*). However, to
achieve a ceiling-panel overlapping dimension
of 15 mm/0.6", the spacing between the ceiling
and the unit should be 20 mm/0.8" or less. If the
spacing between ceiling and the unit is over 20
mm/0.8", attach sealing material in the part or
recover the ceiling.
NOTE:
For other installation than
standard installation contact
your dealer for details.
