Purcase Notes :

• 1.Quite often certain vehicles may have two different parts for the same application to ensure you are receiving the correct part for your vehicle you will need to send us the part numbers from the original part fitted to your vehicle. If you need assistance to make sure that this part will fit your vehicle, please send us the photo of your old compressor , the VIN and/or the year, make, model and engine size of your vehicle so that we may confirm it for you. We also recommend using the compatibility chart in order to make sure that this compressor will fit your vehicle.

• 2.When you want to enjoy the coolest interiors in your vehicle, then you need to check the working condition of the air conditioning system. The main component in the AC system which is compared to the heart of the human body is the A/C compressor. The main function of the A/C compressor is to control and regulate the flow of refrigerant throughout the system. Located in front of the system, the AC compressor is one of the two junctions which separate the high pressure and the low pressure sides of the air conditioning system. Working in a closed loop system, the AC compressor draws the refrigerant from the evaporator in the low pressure side, compresses and pushes it to the condenser in the high pressure side of the system.

• 3. The item pictured might be slightly different from the actual product sent. It may require the use of the OE manifold as it is a majority of the time not included. You may also need to splice the connector. If you have any questions regarding the product, please do not hesitate to contact us directly.

• 4. For safty reason by air express,the compressor comes with no oil, You must add specified oil to the compressor. Please look into your vehicles specifications.

Expansion Valve System

1)High pressure side

Low pressure R134a vapor entering the compressor is compressed to become high pressure/temperature R134a vapor. This is then circulated along with lubricant oil to the condenser. As the high pressure/temperature vapor travels through the condenser, heat is released to the cooler ambient air passing over the condenser tubes condensing the vapor into a liquid. This high pressure/temperature liquid then travels through the filter drier onto the expansion valve where a small variable orifice provides a restriction against which compressor pushes.

2) pressure side

Suction from the compressor pulls the high pressure/temperature liquid R134a through small variable orifice of the TX valve and into the low-pressure side of the A/C system.

The R134a is now under low pressure/temperature vapor where heat from the cabin being blown over the evaporator coil surface is absorbed into the colder low pressure refrigerant The R134a is then pulled through the evaporator and into the

compressor.

The A/C cycle begins again as the R134a vapor is compressed and discharged under pressure.

3)Heat transfer

R134a in the LOW-PRESSURE side is COLD and can absorb large quantities of heat from the air moving over the evaporator.

R134a in HIGH-PRESSURE side is HOT and the cooler ambient air moving over the condenser can absorb the heat from it.

Summary

- When the R134a pressure is low, the R134a temperature is low.

- When the R134a pressure is high, the R134a temperature is high.

Tips:

- CONTACT US. We are dedicated professionals that only deal and specialize in automotive air conditioning. We can assist with any installation questions,

system capacity requirements and have all additional parts for your a/c system.

- After checking or filling the oil, turn the clutch on the compressor 10 times to distribute the oil inside.

- Check how much oil the compressor contains even if it’s brand new.

You do not want to end up doing the job twice simply because there was an insufficient amount of oil added to the compressor.

- Replace the schrader valves anytime you service your a/c system.

- Check relays and pressure switches.

- After flushing, make sure that there is no flush liquid in the system by using compressed air or nitrogen.

- Make sure the condition of the condenser is so that the performance is sufficient to maintain proper temperature in the system. A non-conforming condenser may cause overheating of the compressor.
