*1 Length that meets the piping work conditions stated in the Installation Manual, guarantees the proper oil return to
the unit, and prevents refrigerant overcharge.
*2 Indicates an equivalent length.

2-2. Usage conditions/environment
Follow the condition/environment specified below for installation.
Do not install the unit on moving vehicles such as cars
or ships.
Do not install the unit in a place where acidic solutions
or sprays containing sulfur are used frequently.
Avoid unsuitable places (hot springs, places where
chemicals are frequently used) for installation.
Install the unit in an area where the noise from the unit
will not disturb the neighbors.
Do not install the unit in a place where it is subjected to
radiant heat from other heat sources.
Properly install the unit on a stable, load-bearing sur-
face.
Do not install the unit in any environment where it can
be exposed to airborne iron or copper powder, acidic or
alkaline atmosphere, or an accumulation of a large
amount of sand containing sea salt particles. Such en-
vironments can cause corrosion of the aluminum pipes.
