2.3. Choosing the outdoor unit installation location
• Avoid locations exposed to direct sunlight or other sources of heat.
• S elect a location from which noise emitted by the unit will not inconvenience
neighbors.
• S elect a location permitting easy wiring and pipe access to the power source and
indoor unit.
• Avoid locations where combustible gases may leak, be produced, flow, or accumu-
late.
• Note that water may drain from the unit during operation.
• Select a level location that can bear the weight and vibration of the unit.
• A void locations where the unit can be covered by snow. In areas where heavy
snow fall is anticipated, special precautions such as raising the installation location
or installing a hood on the air intake must be taken to prevent the snow from
blocking the air intake or blowing directly against it. This can reduce the airflow and
a malfunction may result.
• Avoid locations exposed to oil, steam, or sulfuric gas.

carried from the bottom, hands or fingers may be pinched.
