1. Rated voltage: 220V, rated frequency: 50HZ, and operating voltage range: 187-242V. If the voltage is higher than 242V or lower than 187V, please install a power regulator with a capacity of more than 500- 1000W before using it to avoid damage.

2. The rated conductor is easily 6A, 10A, and the cross-sectional area of the conductor is 7.5mm2 The conductor can be single strand or multi-strand, and a fuse with rated current of 15A is required.

3. Single-phase three-level power socket must be used. And have a good grounding wire.

Note: the ground wire connection is absolutely not allowed to be connected to the water pipe or gas pipe.

4. When it is necessary to clear the dust on the cabinet and condenser, it must not be washed with water to avoid damage to electrical components.

5. Flammable, volatile, explosive, corrosive and toxic substances cannot be put in the box.
