2. SELECTING THE INSTALLATION LOCATION
2-1 INDOOR UNIT
•
Where airfl ow is not blocked.
•
Where cool air spreads over the entire room.
•
Maximum refrigerant piping length between indoor unit and outdoor unit is 30 m
and the difference of height of both units is 15 m.
•
Rigid wall without vibration.
•
Where it is not exposed to direct sunshine.
•
Where easily drained.
•
At a distance 1 m or more away from your TV and radio. Operation of the air
conditioner interferes with radio or TV reception in areas where reception is weak.
An amplifi er may be required for the affected device.
•
In a place as far away as possible from fl uorescent and incandescent lights (so
the infrared remote control can operate the air conditioner normally).
•
Where the air fi lter can be removed and replaced easily.
2-2 OUTDOOR UNIT
•
Where it is not exposed to strong wind.
•
Where airfl ow is good and dustless.
•
Where it is not exposed to rain and direct sunshine.
•
Where neighbours are not annoyed by operation sound or hot air.
•
Where rigid wall or support is available to prevent the increase of operation sound
or vibration.
•
Where there is no risk of combustible gas leakage.
•
When installing the unit at a high level, be sure to fi x the unit legs.
•
Where it is at least 3 m away from the antenna of TV set or radio. Operation of the
air conditioner interferes with radio or TV reception in areas where reception is
weak. An amplifi er may be required for the affected device.
•
Install the unit horizontally.
•
Please install it in an area not affected by snowfall or blowing snow. In areas with
heavy snow, please install a canopy, a pedestal and/or some baffl e boards.
Note:
