The “Warning” items are especially important since they can lead to death or serious injury if they are not followed closely. The “Caution” items can also lead to serious accidents under some conditions if they are not followed. Therefore, be sure to observe all the safety caution items described below.  \nAbout the pictograms  \n△ This symbol indicates an item for which caution must be exercised.  \nThe pictogram shows the item to which attention must be paid.  \n○ This symbol indicates a prohibited action.  \nThe prohibited item or action is shown inside or near the symbol.  \n● This symbol indicates an action that must be taken, or an instruction.  \nThe instruction is shown inside or near the symbol.  \nAfter the repair work is complete, be sure to conduct a test operation to ensure that the equipment operates Normally, and explain the cautions for operating the product to the customer.  \n1.2.1 Embedded wire checking before installation Check the embedded wire diameter suitable to request:  \n(Power supply from indoor: 2.5kw ≥1 .0mm2 3.5kw,5kw ≥1 .5mm2 7kw ≥2.5mm2 ; Power supply from outdoor ≥1 .0mm2 )  \nCheck the embedded wire are four roots, L/N/COM/GND; GND is needed, if not, thunder or high voltage wave from power grid will impact to the performance  \nUsing a multi-meter to test short circuit of the four roots wires, make sure no short circuit happen.  \n1.2.2 Caution in Repair  \n| Warning |  |\n| --- | --- |\n| Be sure to disconnect the power cable plug from the plug socket before disassembli","cbCaioUJWFnoWXxe","https://ap.wps.com/l/cbCaioUJWFnoWXxe","pdf",14643466,56,"English","# Introduction\n## Model name explanation\n## Safety Cautions\n## Pictograms and repair precautions","[{\"question\":\"Who is this service information intended for?\",\"answer\":\"The manual is designed for experienced repair technicians only and is not intended for use by the general public.
