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 snowbreak 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.
5.
If the outdoor units are installed in areas with heavy snowfall, the
installation of a snowbreak hood is required. This is available as an
optional accessory. If the units are installed in a location where the
ambient temperature can drop below –10°C, install a windbreak
board or a snowbreak hood.
