Notes:
a. The rated cooling capacity data is measured under the following work condition: Indoor Temperature is 27ćDB,
1 9 ćWB. Outdoor Temperature is 35 ćDB.The rated heating capacity data is measured under the following work
condition: Indoor Temperature is 20ćDB. Outdoor Temperature is 7ćDB, 6ćWB.
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.
