Notes:
1. If the system is running in cooling mode, when the ambient temperature is lower than -5℃ or higher than 48℃, the
units will stop running for protection control.
2. These figures base on the operation conditions between indoor units and outdoor units:
Equivalent pipe length is 5m, and height difference is 0m.
Precaution:
The indoor relative humidity should be lower than 80%. If the air conditioner works in an environment with a relative
humidity higher than mentioned above, the surface of the air conditioner may condensate. In this case, it is recommended
to set the air speed of the indoor unit to high.
