WARNING
Make sure to provide for adequate measures in order
to prevent that the outdoor unit be used as a shelter
by small animals.
Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the unit clean.
The equipment is not intended for use in a potentially explosive
atmosphere.
Choose a place solid enough to bear the weight and vibration of
the unit, where the operation noise will not be amplified.
Choose a location where the hot air discharged from the unit or
the operation noise will not cause a nuisance to the neighbours
of the user.
Avoid places near a bedroom and the like, so that the operation
noise will cause no trouble.
There must be sufficient space for carrying the unit into and out
of the site.
There must be sufficient space for air passage and no
obstructions around the air inlet and the air outlet.
The site must be free from the possibility of flammable gas
leakage in a nearby place.
Locate the unit so that the noise and the discharged hot air will
not annoy the neighbours.
Install units, power cords and inter-unit cables at least 3 m away
from television and radio sets. This is to prevent interference to
images and sounds.
