*1 Cooling capacity is based on use with an ambient temperature/humidity of 25°C/50% RH at the end of a 2-meter duct.
The cooling capacity in parentheses ( ) is based on use with an ambient temperature/humidity of 30°C/70% RH at the
end of a 2-meter duct.
*2 Heating capacity is based on use with an ambient temperature/humidity of 25°C/50% RH at the end of a 2-meter duct.
*3 Dehumidification capacity is based on use with an ambient temperature/humidity of 30°C/70% RH at the end of a 2-meter duct in dry mode.
*4 Temperature control precision is based on the method prescribed in JTM K01 Constant Temperature and Humidity
Chambers - Performance Testing Method and Performance Indication Method (Japan Testing Machine Association).
Only the value indicated by the temperature controller built into the air conditioner at the main unit air outlet is
guaranteed to be precise, and thermal interference due to the duct, etc. is not covered by the precision guarantee.
In addition, this product is designed to reduce temperature fluctuations in the air, so the absolute temperature value is not guaranteed.
(A bias function for compensation is built into the system.)
*5 Temperature control may not be possible even within the set temperature control range depending on the ambient temperature/humidity.
*6 Control at the set value may not be possible depending on the operating environment.
*7 Use of an auxiliary fan is recommended to secure the blowoff air volume at the duct in situations with significant
pressure loss due to a long duct, etc.
*8 Dimensions do not include control panel protrusions, blowout flanges, and casters and their mounting areas.
*9 Use a power supply voltage within ±10% of the rated voltage.
*10 The current consumption and power consumption fluctuate depending on the ambient temperature/humidity and
the operating conditions.
*11 Waste heat is discharged from air-cooled systems. (An optional exhaust chamber is available.)
*12 Values measured at a distance of 1 meter from the front of the device.
