4. Fixing hanging bolts
4.1. Fixing hanging bolts
(Use M10 hanging bolts. The bolts should be procured locally.)
(Give site of suspension strong structure.)
Hanging structure
•
Ceiling: The ceiling structure varies from building to one another. For detailed
information, consult your construction company.
1 Reinforcing the ceiling with additional members (edge beam, etc.) must be
required to keep the ceiling at level and to prevent the ceiling from vibrations.
2 Cut and remove the ceiling members.
3 Reinforce the ceiling members, and add other members for fixing the ceiling
boards.
For wooden construction
•
Use the tie beam (for one story building) or second-floor beam (for two story
building) as strength members.
•
To hang the air-conditioner, use a hard square timber of more than
6 cm if the distance between beams is less than 90 cm and a hard square
timber of more than 9 cm if the distance between beams is less than 180 cm.

As shown in the figure below, fix the hanging bolts, or use square timbers to fix
the hanging bolts.
5. Installing the unit
5.1. Hanging the unit body
s Bring the indoor unit to an installation site as it is packed.
