By following these easy steps, you possibly can simply add oil to your A/C compressor and hold your system working easily.
Earlier than including oil, it’s important to find out the sort and quantity of oil required on your particular compressor. Seek the advice of the producer’s specs or consult with the compressor’s oil fill port for steerage. Usually, compressors use polyalkylene glycol (PAG) oil, which is available in varied viscosities. The proper viscosity of oil will guarantee correct lubrication and stop the compressor from overheating or seizing. Moreover, be sure that the oil you utilize is clear and free from contaminants to keep up the integrity of the system.
After you have the mandatory oil and instruments, find the compressor’s oil fill port. This port is often a small screw-on cap or plug on the facet or backside of the compressor. Rigorously take away the cap and insert the oil injector or syringe into the fill port. Slowly inject the oil into the compressor whereas monitoring the oil stage by the sight glass or dipstick (if out there). Fill the compressor to the really useful stage, as specified by the producer’s directions. Keep away from overfilling, as extra oil can result in foaming and diminished system effectivity.
Figuring out the Compressor
The A/C compressor is the guts of the air-con system. It’s answerable for compressing the refrigerant gasoline and circulating it by the system.
