Foundation
Set the out margin of the anchor bolt to 0.6" (15 mm) or less .
• When the unit is to be installed in a location where it is likely to be exposed to strong winds or where the foundation
is unstable, additional measures must be taken to prevent tip-over as shown in the figure below.

CAUTION
• Carry out the installation work by following the prescribed procedure to help prevent the unit from shaking in the
event of strong winds, earthquakes, etc.
• Failure to carry out the installation work as prescribed may lead to the unit tipping over, in turn causing an accident.
For reference
If a heating operation is to be continuously performed for a long time under the condition that the outdoor temperature
is 32 °F (0 °C) or lower, draining defrosted water may be difficult due to the bottom plate freezing, resulting in trouble
with the cabinet or fan.
Attach a snow stand, snow hood, etc. to the outdoor unit for use in snowfall areas.
It is recommended to procure an anti-freeze heater locally to safely install the air conditioner.
For details, contact the dealer.

Refrigerant Piping
Leading out the pipes
• The indoor/outdoor unit connecting pipes can be connected in any of 3 directions. Use a screwdriver to punch out
the knockout part of the piping/wiring panel or base. Wear heavy work gloves to protect yourself from injury while
doing this work. After punching out the knockout hole in a manner which ensures that the pipes and wires will not be
damaged in any way, remove the burrs from around the hole. Use the protective edge guard around the opening.
