The magnitude of potential damages or injuries is classified as either a WARNING or a CAUTION.  \nWARNING  \n Do not power the system using an extension cable or with wiring smaller than the specified gauge. Do not share the electrical circuit with other appliances. Improper or insufficient power supply can cause undesirable operation, fire, or electrical shock.  \n When connecting refrigerant piping, do not let any substances or gases other than the specified refrigerant enter the unit. The presence of other gases or substances will lower the unit’s capacity, and can cause abnormally high pressure in the refrigeration cycle. This can also cause explosion and injury, as well as permament equipment failure. Remember: No dust, humidity or airis allowed to enter.  \n Do not allow children to play with or around the air conditioner. Children near the unit must be supervised at all times.  \n1. Installation must be performed by a licensed and trained technician. Defective installation can cause water leakage, electrical shock, or fire. The usage of proper tools is a requirement.  \n2. Installation must be performed according to the installation instructions. Improper installation can cause water leakage, undesired performance, electrical shock, or fire.  \n(In North America, installation must be performed in accordance with ","cbCaimDUKsmeO7wL","https://ap.wps.com/l/cbCaimDUKsmeO7wL","pdf",9813510,46,"English","# Installation Manual\n## Safety Precautions\n## Components and Accessories\n## Indoor Unit Installation\n## Outdoor Unit Installation\n## Operating Instructions\n## Troubleshooting\n## Appendix","[{\"question\":\"Who is allowed to perform the installation and repairs?\",\"answer\":\"Installation must be performed by a licensed and trained technician.
