prevent vibration and noise.

use stands to only support the corners.

• The height of the foundation must be at least 5-7/8 in. (150 mm )
from the floor.
In heavy snowfall areas, this height should be increased, depending
on the installation place and condition.
• The unit must be installed on a solid longitudinal foundation (steel
beam frame or concrete) and make sure the base under the unit is
larger than the gray marked area.

*1 In areas where compliance with the FL Building Code is required,
fix at 9 and 10 with foundation bolts.
• Fasten the unit in place using 4 foundation bolts
1/2 in. (M12). It is best to screw in the foundation
bolts until their length remains 13/16 in. (20 mm)
above the foundation surface.

NOTE
• There are restrictions on the refrigerant pipe connecting order
between outdoor units in the case of the multi system.
See 1.2.2. Outdoor units combinations on page 2 for detail.
•
When installing on a roof, make sure the roof floor is strong enough
and be sure to waterproof all work.
• Make sure the area around the machine drains properly by setting
up drainage grooves around the foundation.
• Drain water is sometimes discharged from the outdoor unit when it
is running.
• For anti-corrosion type, use nuts with resin washers. If the paint on
nut connections comes off, the anti-corrosion effect may decrease.
