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.

No


Is R404A freon compatible with R409a?

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


Do you add liquid or vaor to the low side?

it depends on the gas you are using. for ex\mple r134a and r22 you charge vapour through the low side and some gases are liquis charge only r404a r409 r407c and others these you charge carefully and slowly as liquid through the low side.


Can i replace r404a with r134a?

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.
