2.12 Operation Range
This unit has been designed for cooling operations under low ambient temperatures down to
23°F (-5°C) DB
*3)
.
This wide operation range enables cooling even in winter in buildings with high internal heat gains resulting
from lighting, people and machines, particularly in areas such as shops, lecture rooms, and data processing
areas. Heating operations under low ambient temperature down to -4°F (-20°C) WB
*5)
can also be
accomplished.

*1) When the outdoor air temperature is 100
o
F DB (38
o
C DB) or more and the outdoor unit operation capacity
ratio is 100% or more, the outdoor unit will be Thermo-OFF to protect the compressor from failure.
*2) When the outdoor air temperature is 109
o
F (43
o
C) or more during the outdoor unit cooling operation, the
maximum connectable indoor unit capacity ratio is 100%.
*3) When operating the outdoor unit under the low cooling load conditions and in the low outdoor air
temperature, (approx. 50
o
F DB (10
o
C DB) or less), the indoor unit will be Thermo-OFF* to prevent the heat
exchanger of the indoor unit from being frosted.
*4) When operating the outdoor unit under low heating load conditions and the outdoor temperature is
59
o
F DB (15
o
C DB) or more, the outdoor unit will be Thermo-OFF* to protect the compressor from failure.
*5) Operation in the outdoor temperature of 5~-4
o
F WB (-15~-20
o
C WB) is assumed to limited conditions such
as start-up in early morning.
Long time operation in this condition may shorten the life of the compressor.
* Thermo-ON: The outdoor unit and some indoor units are running.
Thermo-OFF: The outdoor unit and some indoor units stay on, but don’t run.
