Notes:
a. The rated cooling capacity data is measured under the following work condition: Indoor Temperature is 27ºCDB, 19ºCWB. Outdoor
Temperature is 35ºCDB. The rated heating capacity data is measured under the following work condition: Indoor Temperature is 20ºCDB.
Outdoor Temperature is 7ºCDB, 6ºCWB.
b. The data will change with the change of products. Refer to those parameters listed on nameplate.
c . Noise was tested in semi-silenced room, so the actual noise value will be a little higher for change of ambient.
