Follow these instructions to prevent distortion when the compressor starts:
• The unit must be connected to its individual sub-circuit. Ensure sub-circuit mains are of adequate size to ensure
minimal voltage drop at supply terminals.
• No other equipment should be connected to the same sub-circuit as the air conditioning unit.
• The unit’s power information can be found on the rating sticker on the product.
NOTE
The air conditioners circuit board (PCB) is designed with a fuse to provide overcurrent protection. The specifications of the
fuse are printed on the circuit board, such as: T5A/250VAC, T10A/250VAC, etc.
