Refrigerant should be removed from the condenser outlet when:
300psi
Liquid receivers are used to store the liquid refrigerant after it leaves the condenser. It should be located below the condenser to enable natural flow. The receiver may be constructed either vertically or horizontally and should have sufficient capacity to hold the entire system's refrigerant charge. The design should be such that only liquid refrigerant leaves the receiver and enters the liquid line. by vishal mahnn
When the condensor was removed a generous amoint of oil (PAG) was removed with the old one. I should say, Was not recovered. It is possible that this oil was not replaced when the new one waas installed, This imbalance of oil to refrigerant will cause this effect. There is a formula.3.3-8% oil to refrigerant ratio. oil= refrigerant chargex0.06+2.2divided by0.09.. add xtra 10% for long hoses..
When recovering refrigerant from an air-cooled system with its condenser positioned several feet above the evaporator, you should access the service valve on the evaporator. This allows for effective recovery of refrigerant, as it minimizes the risk of trapping refrigerant in the condenser. Additionally, ensure that the recovery unit is positioned at a lower elevation than the evaporator to facilitate gravity-assisted refrigerant flow. Always follow safety and local regulations during the recovery process.
R134a refrigerant pressure should be around 28-32 psig with good airflow across condenser(radiator)coil and engine rpm at or around 1500
When testing the efficiency of a water-cooled condenser, the refrigerant condensing temperature should indeed be higher than the leaving water temperature to ensure effective heat transfer. This temperature difference allows the refrigerant to release heat to the water, facilitating condensation. If the condensing temperature is not sufficiently above the leaving water temperature, the condenser may not operate efficiently, leading to reduced system performance and potential overheating. Properly managing this temperature difference is crucial for optimal condenser operation.
To check if the condenser is working, you can start by inspecting the air conditioning unit or refrigeration system for any signs of frost or ice buildup on the coils, which can indicate poor airflow or a refrigerant issue. Next, feel the air coming out of the condenser; it should be warm, as it releases heat from the refrigerant. Additionally, you can monitor the pressure readings on the condenser's service ports with a gauge; proper pressure levels indicate that the condenser is functioning correctly. If these checks suggest a malfunction, it may require further investigation or professional service.
Should be located in the line that goes between the condenser outlet and evaporator inlet. Look for the dimples in the line.
Yes, it is not recommended to cover a microwave outlet as it needs proper ventilation for safety reasons. Blocking the outlet can lead to overheating and potential fire hazards.

It is located in the liquid side. Most of the time it is in the evaporator inlet. The other place they are located is at the outlet of the condenser. Follow the line that runs from the condenser ( a/c radiator) to the cab, there should be a nut holding two pieces together. It'll be in there, I think it slides in toward the condenser.
