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 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.
• 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 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 mal-
function 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.

Verification
The rated capacity should be determined by observing the table below. The unit's
quantities are limited as shown in the following table 2. For the next step, make sure
that the total rated capacity selected will stay in a range of 50% - 130% of the outdoor
unit capacity.
• PUMY-P100 5.6 - 14.6 kW
• PUMY-P125 7.1 - 18.2 kW
• PUMY-P140 8.0 - 20.2 kW

Combinations in which the total capacity of indoor units exceeds the capacity of the
outdoor unit will reduce the cooling capacity of each indoor unit below their rated
cooling capacity. Thus, combine indoor units with an outdoor unit within the outdoor
unit's capacity, if possible.
* Only when all the indoor units are 1.5 kW model, 12 indoor units can be connected
to 1 outdoor unit.
