2.2. Choosing the outdoor unit installation location
•
Avoid locations exposed to direct sunlight or other sources of heat.
•
Select a location from which noise emitted by the unit will not inconvenience
neighbors.
•
Select 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 ac
-
cumulate.
•
Note that water may drain from the unit during operation.
•
Select a level location that can bear the weight and vibration of the unit.
•
Avoid locations where the unit can be covered by snow. In areas where heavy
snow fall is anticipated, special precautions such as raising the installation loca-
tion 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.
•
Use the transportation handles of the outdoor unit to transport the unit. If the unit
is carried from the bottom, hands or fingers may be pinched.
