20 minutes continuous operation by maximum airow and maximum compressor speed is
possible. Rapid cooling and heating makes the room comfortable quickly.

z *Only available with Wireless RC.
The room temperature can be set to go no lower than 50°F (10°C),
thus ensuring that the room does not get too cold when not occupied
Caution)
When the room temperature is higher than 50°F (10°C), “•MIN. HEAT” operation will not start. Operation starts and maintains the room
temperature at 50°F (10°C) when the temperature drops below 50°F (10°C).
When “•MIN. HEAT” operation stops, the room set temperature quickly returns to the preset temperature.
Outdoor unit low noise
z *Only available with Wireless RC.
When air-conditioner operates in large capacity, operation noise of outdoor unit will be suppressed. In case
of room temperature being close to setting temperature, operation noise might not decrease.

NOTE :
• Specications are based on the following conditions.
Cooling : Indoor temperature of 80°F (26.67°C) DB / 67°F (19.44°C) WB, and outdoor temperature of 95°F (35°C) DB / 75°F (23.9°C) WB.
Heating : Indoor temperature of 70°F (21.11°C) DB / 59°F (15°C) WB, and outdoor temperature of 47°F (8.33°C) DB / 43°F (6.11°C) WB.
Pipe length : 24ft.7in (7.5m), Height difference:0 m. (Outdoor unit-Indoor unit)
• The protective function might work when using it outside the operation range.
*1: The maximum current is the maximum value when operated within the operation range.
*2: These are the measured values in the manufacturer’s anechoic chamber.
Because of the surrounding sound environment, the sound levels measured in actual installation conditions might be higher than the specied values here.
