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.
