Notes:

1. Nominal cooling capacities are based on the following conditions:

Indoor temp: 26.7°CDB, 19.4°CWB; Outdoor temp: 35°CDB，23.9°CWB;

2. Nominal heating capacities are based on the following conditions:

Indoor temp: 21.1°CDB，15.6°CWB; Outdoor temp: 8.3°CDB, 6.1°CWB;

3. Actual noise level may differ, depending on the room structure, etc., since these noise values are from an

anechoic room.
