4. Instrukcja instalacji

Proper installation is critical for the longevity and performance of your new A/C compressor. It is strongly recommended that this procedure be performed by a qualified automotive service technician.

Kontrole przed instalacją

• Płukanie systemu: Thoroughly flush the entire A/C system to remove old oil, debris, and contaminants. Failure to do so can lead to premature compressor failure and void the warranty.
• Orifice Tube/Expansion Valve: Replace the orifice tube or expansion valve. These components can harbor debris and restrict refrigerant flow.
• Accumulator/Receiver Drier: Always replace the accumulator or receiver drier. This component absorbs moisture and filters debris, and its capacity is limited.
• Refrigerant Oil: Ensure the correct type and amount of refrigerant oil (PAG or POE, as specified by the vehicle manufacturer or compressor instructions) is used. Distribute the oil properly throughout the system.
• Sprawdzenie szczelności: Inspect all hoses, lines, and connections for signs of wear or damage. Replace as necessary.

5. Działanie

Once installed and properly charged, the A/C compressor functions as the heart of your vehicle's air conditioning system, circulating refrigerant to provide cooling. To ensure optimal performance and longevity:

• Operate your A/C system periodically, even during colder months, for at least 10-15 minutes. This helps to circulate refrigerant oil, lubricate seals, and prevent component degradation.
• Avoid running the A/C system with low refrigerant levels, as this can cause the compressor to overheat and fail.

6. Konserwacja

Regular maintenance helps extend the life of your A/C system and compressor:

• Kontrola poziomu czynnika chłodniczego: Have your A/C system's refrigerant level checked annually by a professional. Low levels can indicate a leak and lead to compressor damage.
• Kontrola paska: Regularly inspect the serpentine belt that drives the compressor for cracks, fraying, or excessive wear. Replace if necessary.
• Czyszczenie skraplacza: Keep the condenser (located in front of the radiator) free of leaves, dirt, and debris to ensure proper heat dissipation.
• Filtr powietrza kabinowego: Replace your cabin air filter regularly to maintain good airflow and prevent strain on the blower motor.
