• 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.

beam frame or concrete) and make sure the base under the unit is
larger than the gray marked area.

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.
