Selectable external static pressure of the outdoor unit
Y-Series EP Y-Series P R2-Series
The static pressure specification for the outdoor unit can be selected (0, 30, 60, or 80 Pa).
This facilitates installation of the unit on each floor of a high-rise building or on balconies.
* The static pressure that can be set varies depending on the model.
* Noise level and power consumption vary depending on the static pressure setting.
* For details of the installation restrictions, refer to the DATABOOK.
Operation at high outside temperatures
Y-Series EP Y-Series P R2-Series
In built-up areas where the passage of air is blocked, the warm air that is discharged from the outdoor units
may cause high temperatures around the units. YNW has an expanded guaranteed operation range of up to 52°C
[125°F], so it can be used reliably even if the outdoor air temperature rises abnormally during the hot summer daytime.
Example of flow analysis
Built-up area with buildings and outdoor units
If the passage of air is blocked in a built-up area, the
high temperature air discharged from the outdoor
units may linger around the units.
• Models for use in outside temperatures of up to 52°C
* These images show the High efficiency R2 type.

OUTDOOR UNIT FUNCTIONS
Long exhaust hoods can be connected.
This facilitates installation of the unit on each
floor of a high-rise building or on balconies.
Maximum external static pressure

Installation on each floor of a high-rise building
When the outdoor units are installed on the
balconies, the high temperature air discharged
from the units may be trapped in the balcony.
