• The installation service spaces shown in the illustrations are based on an air intake temperature of 95°F(35°C)(DB) for
COOL operation. In regions where the air intake temperature regularly exceeds 95°F(35°C)(DB), or if the heat load of
outdoor units is expected to regularly exceed the maximum operating capacity, reserve a larger space than that
indicated at the air intake side of the units.
• Regarding the required air outlet space, position the units with consideration to the space required for the onsite
refrigerant piping work as well. Consult your dealer if the work conditions do not match those in the illustrations.
(4) Precautions on installation
NOTE
If drain holes of the outdoor unit are covered by a mounting base or by floor surface, raise the unit in order to provide a
free space of more than 5 in. (130 mm) under the outdoor unit.
Foundation work
• Check the strength and level of the installation ground so that the unit does not produce vibration or noise post
installation.
• In accordance with the foundation drawing in the figure, fix the unit securely using the foundation bolts.
• It is best to screw in the foundation bolts until their lengths are 0.8 in. (20 mm) from the foundation surface.
• Fix the outdoor unit to the foundation bolts using nuts with resin washers (1) as shown in the figure.
• Avoid strong wind blowing directly to the outdoor fan and heat exchanger. If there is no need to install the outdoor
machine in the open space of the building or the enclosure, the following two ways can be used to avoid fan reversal or
damage caused by strong wind.
(1) Using the windshield
The top and two side surfaces must be exposed to open space,
and barriers on at least one side of the front and back shall be
lower than the outdoor unit.
