Notes:
1. Nominal cooling capacities are based on the following conditions:
Indoor temp: 80°FDB, 66°FWB; Outdoor temp: 95°FDB; Equivalent ref. piping: 5m (horizontal)
2. Nominal heating capacities are based on the following conditions:
Indoor temp: 68°FDB; Outdoor temp: 44°FDB, 43°FWB; Equivalent ref. piping: 5m (horizontal)
3. Actual noise level may differ, depending on the room structure, etc., since these noise values are from an
anechoic room.

8. Field Wiring
1. To avoid the electrical shock, please connect the air conditioner with the ground lug.
The main power plug in the air conditioner has been joined with the ground wiring,
please do not change it freely.
2. The power socket is used as the air conditioner specially.
3. Do not pull the power wiring hard.
4. When connecting the air conditioner with the ground, observe the local codes.
5. If necessary, use the power fuse or the circuit, breaker or the corresponding scale
ampere.
