Notes:
#. Connection piping diameter of indoor unit is the inlet and outlet pipe of the indoor unit. When the length
of the refrigerant pipe between indoor and outdoor is not more than 30m, please connect the straight
pipe as the accessory in indoor unit with inlet refrigerant pipe to change the diameter of liquid pipe to
Ф9.52. When the length of the refrigerant pipe is more than 30m and less than 50m, please connect
the straight pipe (prepared in site) with outlet refrigerant to change the diameter of gas pipe to Ф28.1.
1. T1 nominal cooling capacities are based on the following conditions,
Indoor temperature is 27°C DB/19°C WB; Outdoor temperature is 35°C DB; Equivalent refrigerant
piping: 7.5m (horizontal).
2. T3 nominal cooling capacities are based on the following conditions:
Indoor temperature is 27°C DB/19°C WB; Outdoor temperature is 46°C DB; Equivalent refrigerant
piping: 7.5m (horizontal).
3. The noise is measured in the semi noise suppression lab.
