(2) When installing the outdoor unit's in a place exposed to strong wind, pay special attention to the following.
5 m/sec or more strong wind blown against the outdoor unit's outlet side causes the oudoor unit to
deteriorate in air volume and suck in the air blown out of its outlet side (short circuit), and the following effects
may result.
- Performance is degraded.
- Operation stop due to increase in pressure.
If a very high fan strength is used continuously from the front of the oudoor unit outlet side, the fan might turn in
reverse at high speed, and become damaged.
(3) Following the installation place, it is expected that the influence of the strong wind is great.
• The flat area which receives the adverse wind such as typhoon directly since
there is no obstacles such as buildings and mountains. (Including coast line, shoreline of lake and mountain region.)
• The installation place that no obstacles around the outdoor unit to prevent the adverse wind,
for example, walls and buildings that are higher than the applicable outdoor unit, etc.
Please take measures when installing especially on a rooftop.
• Since the outdoor unit may fall down, attach the fixture for preventing overturning(option).

• The installation servicing spaces shown in these drawings are based on the outdoor unit inlet area temperature of 35
for COOLING operation.
If the planned inlet area temperature exceeds 35
and exceeds the maximum operating capacity, secure a larger space than that indicated by the inlet dimensions
in these drawings.
• For installation, consider both pedestrian and air flow paths and choose a suitable pattern from these drawings to match
the space available field. (If the number of units to be installed exceeds the patterns in these drawings,
consider there are no short-circuits.)
• Regarding the front space, position the units with consideration to the space required for the refrigerant piping work.
(Consult your dealer if the work conditions do not match those in the drawings.)
• Secure appropriate space when using a side piping outlet.
