The pressure of R404A for recharging a refrigerator can vary depending on the specific refrigerator model and the manufacturer's recommendations. However, typical recommended operating pressures for R404A refrigerant in a refrigerator range from about 160 psi to 250 psi on the low side and from 250 psi to 350 psi on the high side. It's crucial to consult the refrigerator's instruction manual or a qualified technician to ensure the correct pressure levels are maintained during recharging.
Charging an R404A unit involves connecting a charging hose from a refrigerant cylinder to the low-pressure side of the system. The refrigerant is then added slowly, while monitoring the system's pressure and temperature to ensure proper charging levels are reached. It is recommended to consult a professional technician to ensure correct charging procedures are followed.
To charge a walk-in cooler with R404a refrigerant, you will need to connect a refrigerant cylinder to the system using a manifold gauge set. Open the cylinder valve and slowly add the necessary amount of refrigerant into the system according to the manufacturer's specifications. Be sure to monitor the system pressures and temperatures as you charge it to ensure that it is properly charged.

No
No, you should not use R134a refrigerant to top off an R404A system. R134a and R404A have different chemical compositions and performance characteristics, which can lead to inefficiencies, potential damage to the system, and violation of environmental regulations. It's important to use the specified refrigerant for your system to ensure proper operation and compliance.

R404A is a refrigerant commonly used in medium and high-temperature refrigeration applications, such as in commercial refrigeration and air conditioning systems. It is compatible with various oils, including polyolester (POE) oils, which are commonly used with HFC refrigerants. Equipment designed for R404A should be constructed from materials resistant to chemical breakdown and should ensure proper seals to prevent leaks. Additionally, R404A can typically be used with systems designed for R22, but retrofitting may be required.
No
No r404a is not compatible with r409a, r134a and 404a use the same lubricates and are compatible but r409a use a different lub making them incompatible
No, you cannot directly replace R404A with R134A, as they have different properties and applications. R404A is a blend designed for low-temperature refrigeration, while R134A is typically used in medium-temperature applications, such as automotive air conditioning. Using R134A in a system designed for R404A could lead to inefficiency, inadequate cooling, and potential damage to the system. Always consult with a professional technician before making refrigerant changes.
No. There'll still be residual traces of R22, even if the cylinder is empty, and it won't blend with the R404A. Furthermore, the R22 cylinder will be labeled as such, and it's actually a crime to have such cylinders improperly labeled.

Depends who you purchase it from and in what quantity.
Someone please correct me if I am wrong, but ZP is in relation to the thermal expansion valve. This valve limits pressure and flow through the evaporator. Sporlan uses SZ and SZP to designate the thermostatic charge and is related to refrigerant r404a. Can anyone explain what the S is in relation to?
