Preparation
Precautions for
Installation and Use
Unsuitable Environments
Do not install the unit in the following types of
environments. Doing so may result in malfunctions or
damage to the unit.
Poorly ventilated locations
The intake and exhaust vents prevent the unit’s interior
from overheating. Avoid installation in locations with poor
ventilation, and make sure the intake and exhaust vents are
free from obstructions.
Locations that obstruct the intake and
exhaust vents
If objects are placed near the exhaust vents located on the
top of the unit and on its sides, exhaust will flow into the
intake vents. This may cause the unit’s interior to overheat
and the protection circuit to activate. Be sure to leave
sufficient space for the exhaust to escape when installing
the unit. Maintain a clearance of about 1 m (39
3
/
8
in.)
between the unit and objects.
Locations subject to high temperature and
humidity
Locations subject to sudden temperature
changes
Sudden temperature changes in an enclosed space where
the unit is installed will result in condensation, which may
in turn result in malfunctions. Be careful when using air
conditioners.
