2. INDOOR UNIT INSTALLATION

2-1. CEILING OPENINGS AND SUSPENSION
BOLT INSTALLATION LOCATIONS
• Make an opening in the ceiling 384 mm × 1160 mm in size. This func-
tions as a check window and will be needed later during servicing.
• If the dimensions are not accurate, when the grille is installed there
may be gaps between it and the indoor unit. This may result in drip-
ping water or other problems.
• When deciding on placement, consider carefully the space around
the ceiling and make your measurements generous.
• Ceiling types and building construction differ. Therefore you should
consult with the builder and decorator.
• Using the installation template (4) (top of the package) and the gauge
(supplied as an accessory with the grille), make an opening in the
ceiling so that the main unit can be installed as shown in the diagram.
(The method for using the template and the gauge are shown.)
• Use M10 suspension bolts (E).
• After suspending the indoor unit, you will have to connect the pipes
the direction of the pipes has been determined, place the refriger-
ant and drainage pipes, and the wiring that connects the indoor and
outdoor units in their desired locations before suspending the indoor
unit. This is especially important in cases where the ceiling is already
in existence.
1) Wooden structures
story houses) as reinforcing members.
• Wooden beams for suspending air conditioners must be sturdy
and their sides must be at least 60 mm long if the beams are sepa-
rated by not more than 900 mm and their sides must be at least 90
mm long if the beams are separated by as much as 1800 mm.
• Use channel, duct and other parts procured locally to suspend the
indoor unit.
2) Ferro-concrete structures
• Secure the suspension bolts using the method shown, or use steel
or wooden hangers, etc. to install the suspension bolts (4).
• When the unit is put down with its lower surface facing down, place
packing material (cushion) underneath to prevent horizontal vane
damage.
• The packing material (cushion) is taped to the unit. When using the
packing material, do not remove it from the unit to prevent horizon-
tal vane damage.
