* Cooling/heating/humidification capacity is the value when blown out from the main body when the ambient temperature is 25°C/40%RH.
* The temperature and humidity control accuracy is based on the method prescribed in JTMK01 Constant Temperature Humidistat Bath - Performance Testing Method and Performance Display Method (Japan Testing Machine Association). Only the value indicated by the temperature controller built into the air conditioner at the main unit blow off port is guaranteed to be accurate and thermal interference due to the duct etc. is not covered by the precision guarantee. In addition, the purpose of this product is to suppress temperature fluctuations in the air and so the absolute value of the temperature is not guaranteed. (A bias function for compensation is built into the system.)
*The temperature and humidity may not be controllable even if they are within the set range depending on the ambient temperature and humidity.
*Processing air flow value is taken at the main unit blowout port.
*The above-mentioned dimensions are the dimensions of the main unit. The mounting flange and protrusions are excluded.
*Current consumption and power consumption vary depending on ambient temperature and humidity and operating conditions.
*Waste heat is discharged from the device because it is air-cooled. (with optional exhaust chamber)
*When the ambient temperature drops below the operating ambient temperature, a protection device is activated to automatically stop only the compressor. Since the above-mentioned accuracy cannot be guaranteed in this case, use the equipment within the range of operating ambient temperatures.
・ Do not supply pure water or ultrapure water (conductivity: 1 μS/cm or less, specific resistance: 10 MΩ/cm or more) to the main unit.
・When the humidifier auto blow function is in operation, the temperature and humidity control accuracy may deviate from the specified range.
・Be sure to install a strainer on the water supply side of the humidifier.
・ Be sure to use heat resistant piping (heat resistant to 100 ℃ of higher) for the drainage piping.
・For the actual installation, check the specifications and precautions stated in the instruction manual.
・Contact our nearest sales office if you need an instruction manual in advance for design purposes.
