Notes:
1.
Indoor temperature 27°C DB, 19°C WB; outdoor temperature 35°C DB; equivalent refrigerant piping length 7.5m with zero level difference.
2.
Indoor temperature 20°C DB; outdoor temperature 7°C DB, 6°C WB; equivalent refrigerant piping length 7.5m with zero level difference.
3.
Fan motor speed and air flow rate are from the highest speed to the lowest speed, total 7 rates for each model.
4.
Stable operation external static pressure range. (Note: setting external static pressure outside the unit’s optimal static pressure range may lead to higher
noise levels and lower airflow rate. For the optimal external static pressure range refer to the unit’s installation manual.)
5.
Sound pressure level is from highest level to lowest level, total 7 levels for each model. Sound pressure level is measured 1.4m below the unit in a semi-
anechoic chamber.
6.
Unit body dimensions given are the largest external dimensions of the unit, including hanger attachments.
