▪ In places with weak reception, keep distances of 3 m or more to avoid
electromagnetic disturbance of other equipment and use conduit tubes for
power and transmission lines.
CAUTION
Appliance not accessible to the general public, install it in a secured area, protected
from easy access.
This unit, both indoor and outdoor, is suitable for installation in a commercial and
light industrial environment.
▪ When installing, take strong winds, typhoons or earthquakes into account,
improper installation may result in the unit turning over.
▪ Take care that in the event of a water leak, water cannot cause any damage to
the installation space and surroundings.
▪ When installing the unit in a small room, take measures in order to keep the
refrigerant concentration from exceeding allowable safety limits in the event of a
refrigerant leak, refer to "About safety against refrigerant leaks"[462].
CAUTION
Excessive refrigerant concentrations in a closed room can lead to oxygen deficiency.
▪ Be sure that the air inlet of the unit is not positioned towards the main wind
direction. Frontal wind will disturb the operation of the unit. If necessary, use a
screen to block the wind.
▪ Ensure that water cannot cause any damage to the location by adding water
drains to the foundation and prevent water traps in the construction.
Seaside installation. Make sure the outdoor unit is NOT directly exposed to sea
winds. This is to prevent corrosion caused by high levels of salt in the air, which
might shorten the life of the unit.
Install the outdoor unit away from direct sea winds.
Example: Behind the building.
If the outdoor unit is exposed to direct sea winds, install a windbreaker.
