Your questions need more information as to what you are working on but in general for a vehicle its is as follows..
Using a set of a/c gauges put the blue hose on the low side (suction side) and the red hose on the high side (discharge side) and make sure that there is no freon in the system and if you have freon in the system then you will have to go to an automotive a/c shop and have them reclaim it for you..
Put the yellow hose on your vacuum pump and let it run for about 1 hour and then let it sit for 1 hour so that you can see if it will at least hold the vacuum pulled.
If so then let it run for an additional hour and then start the recharging process remembering to keep the low side readings between 30 to 40psi and the high side between 200 to 250psi depending on the outside temperature…………….

What is meant by restricting liquid refrigerant into a refrigeration system when charging?
Vaporizing the refrigerant
What is meant by restricting liquid refrigeration system when charging?
Vaporizing the Refrigerant
Why does refrigerant pressure decrease in a refrigerant cylinder while charging with vapor?
When vapor refrigerant is pulled out of a cylinder the vapor is reduced and the liquid boils to replace the vapor that has left the cylinder.
What is charging of a compressor?
It means charging the A/C system with the proper kind and amount of refrigerant + oil. Overcharging the system will damage the compressor.
When charging a system with vapor refrigerant from a refrigerant cylinder the cylinder will become?
Lighter, as the refrigerant is boiled off, and colder, as it has absorbed heat, and has a lesser pressure to reflect the current temperature / pressure relationship for the type of refrigerant
What is the disadvantage of a dial scale?
They are more difficult to use when charging refrigerant into a system and more calculations are necessary to determine the amount of refrigerant charged.
How is liquid refrigerant added to the refrigeration system when the system is out of refrigeration?
Liquid refrigerant charging of a system is normally accomplished in the liquid line. For example, when a system is out of refrigerant, liquid refrigerant can be charged into the king valve on the liquid line or receiver.
When filling a charging cylinder the refrigerant that is vented off the top of the cylinder?
Must be recovered
When filling a charging cylinder the refrigerant that is vented off the top of the cylinder .?
Must be recovered
What feature of a digital electronic scale makes them useful for refrigerant charging?
they will suck your dick
When filling a charging cylinder refrigerant that is vented off the top of the cylinder?
Must be recovered
When charging a refrigeration system you add refrigerant on the low side or the high side?
Low
