Notes:
a. The rated cooling capacity data is measured under the following work condition: Indoor Temperature is 27℃
DB, 19℃WB. Outdoor Temperature is 35℃DB. The rated heating capacity data is measured under the following
work condition: Indoor Temperature is 20℃DB. Outdoor Temperature is 7℃DB, 6℃WB.
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.

Notes:
a. The rated cooling capacity data is measured under the following work condition: Indoor Temperature is 27℃
DB, 19℃WB. Outdoor Temperature is 35℃DB. The rated heating capacity data is measured under the following
work condition: Indoor Temperature is 20℃DB. Outdoor Temperature is 7℃DB, 6℃WB.
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.
