NOTE) For patterns 1 and 2
• Wall height for front side no higher than 1500 mm.
• Wall height on the suction side no higher than 500 mm.
• Wall height for sides – no limit
• If the height is exceeded the above, calculate h1 and h2 shown
in the figure below, and add h1/2 to the service space of front
side and h2/2 to the service space of suction side.
CAUTION
1.
An inverter condensing unit may cause electronic noise generated
from AM broadcasting. Examine where to install the main
condensing unit and electric wires, keeping proper distances away
from stereo equipment, personal computers, etc.
Particularly for locations with weak reception, ensure there is a
distance of at least 3 meters for indoor remote controllers, place
power wiring and transmission wiring in conduits, and ground the
conduits.
2.
When installing in a locations where there is heavy snowfall,
implement the following snow measures.
• Ensure the base is high enough that intakes are not clogged by
snow.
• Mount a snow protection hood (optional accessory)
• Remove the rear intake grille to prevent snow from
accumulating on the fins.
3.
If condensate may drip on downstairs (or walkway) depending on
the floor condition, take a measure such as the installation of
central drain pan kit (sold separately).
4.
The refrigerant R410A itself is nontoxic, nonflammable and is safe.
If the refrigerant should leak however, its concentration may
exceed the allowable limit depending on room size. Due to this it
could be necessary to take measures against leakage.
See “Engineering Data” for details.

• Use 2 belts of at least 8m long.
• Place extra cloth in the locations where the casing comes in
contact with the sling to prevent damage.
• Hoist the unit making sure it is being lifted at its center of gravity.
1 Belt sling
