Air Conditioning Maintenance Process:

1. Comprehensive Inspection. When air conditioning units fail, a thorough check is required, including testing parameters such as machine pressure and system operating temperatures at various points. For split systems, this must be done with both indoor and outdoor units connected. To measure the compressor exhaust pressure, please connect the pressure gauge when the machine is stationary to avoid high temperatures and burns during operation. Use your fingers to feel the temperature from the compressor exhaust to the condenser section, first quickly testing some areas to prevent injury.

2. Welding Operations. Prior to welding, release the refrigerant from the system. Always wear protective eyewear to prevent eye injury during welding. During the refrigerant release, operators should not face the process opening or discharge towards others to avoid frostbite from the refrigerant. Adhere to welding operation requirements to prevent poor installation or injury to others.

3. Power Operation. When repairing the outdoor unit of a split system independently, power operation is prohibited when the high-pressure or low-pressure valves are closed to avoid accidents such as system bursting due to excessive pressure or explosions caused by the compressor running in a vacuum. When inspecting the outdoor fan system, power operation is required, and it must be ensured that the air conditioner panel and fan grill are properly installed.
