By following these easy steps, you may simply add oil to your A/C compressor and maintain your system operating easily.
Earlier than including oil, it’s important to find out the sort and quantity of oil required to your particular compressor. Seek the advice of the producer’s specs or discuss 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 forestall the compressor from overheating or seizing. Moreover, be certain that the oil you utilize is clear and free from contaminants to take care of the integrity of the system.
After getting the required 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 degree by way of the sight glass or dipstick (if out there). Fill the compressor to the really useful degree, as specified by the producer’s directions. Keep away from overfilling, as extra oil can result in foaming and decreased 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 fuel and circulating it by way of the system.
