Precautions on Installation
• Check the strength and level of the installation surface so that the unit does not cause
any operating vibrations or noise after installation.
• Fix the unit in place securely using foundation bolts, as in the figure. (Prepare 4
sets of 5/16 inch (M8) or 3/8 inch (M10) foundation bolts, nuts and washers; all sold
separately.)
• It is best to screw in the foundation bolts until their ends are 3/4 inch (20mm) from the
foundation surface.

*Be sure to add the proper amount of additional refrigerant.
Failure to do so may result in reduced performance.
**The suggested shortest pipe length is 10ft (3m), in order to avoid
noise from the outdoor unit and vibration.
(Mechanical noise and vibration may occur depending on how
the unit is installed and the environment in which it is used.)
If strong wind blows into the air discharge side
from the front and there is a danger that the fan
may be damaged, change the orientation of the
air discharge side of the outdoor unit or use an
air direction adjustment grille (sold separately).

In sites with poor drainage,
use block bases for the
outdoor unit.
Adjust foot height until the unit
is level. Otherwise, water
leakage or pooling of water
may occur.
Appearance of outdoor units may differ from some models.
