Air Conditioning Maintenance Process:

1. Comprehensive Inspection. When any air conditioning units encounter malfunctions, a thorough check is required. First, inspect the machine's pressure and the operating temperatures at various system points. For split systems, this must be done with both indoor and outdoor units connected. To measure the compressor exhaust pressure, connect the pressure gauge when the machine is stationary to avoid causing burns due to high temperatures during operation. Use your fingers to feel the temperature of the compressor exhaust to the condenser section pipeline, first quickly试探 a few temperatures to prevent injury.

2. Welding Operations. Prior to welding, release the Freon from the system. Always wear protective goggles to prevent eye injury. During the Freon release, operators must not face the process opening or discharge towards others to avoid frostbite from the Freon. 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 separately, power operation is prohibited with the high-pressure or low-pressure valves closed to avoid system burst accidents due to excessive pressure or explosion accidents caused by the compressor running at vacuum; when inspecting the outdoor fan system, power operation is required, and it must be ensured that the air conditioning panel and fan cover are properly installed.
