1. Start by connecting the vacuum pump to your system. Ensure that all of the valves are closed, and then connect the red hose from the pump to a container large enough to hold any recovered liquid refrigerant.
2. Next, open up both high and low-side service ports on your system with an appropriate wrench or valve core tool, then attach adapters for each port.
Connect one end of the yellow hose from your recovery machine to the low side service port and connect the other end of this hose into a canister containing R134a refrigerant gas and solvent mixture.
3. With everything connected properly, turn on your vacuum pump and allow it run until it reaches its ultimate pressure (usually around 500 microns). After reaching this pressure you should see some movement in either direction between both cans as they pass back & forth gases/liquid respectively.
If not, check that all valves are closed properly or try adjusting their settings accordingly until you do see some activity happening between them while running at full power levels (recommended no more than 7 CFM).
4 . Once there is steady flow of liquid/gas exchange occurring within your setup, shut off power going into vacuum pump (while keeping hoses connected) – allowing time for any remaining air pockets inside system being evacuated out before opening up main valve slowly so as not to cause sudden bursts which could potentially damage components within device itself!
Finally close off valve when desired amount has been achieved successfully recovering R134A refrigerant with use of vacuum pump!
- Begin by turning off the vacuum pump and then disconnecting the hoses from your system
- Make sure all components are turned off so that no pressure will be built up in any of them
- Connect a high-pressure hose to the low side and low-pressure hose to the high side of your system, making sure they are tight and secure with no air leaks present
- Turn on the vacuum pump and allow it to run for about 10 minutes until it reaches a good level of vacuum (around 25 Hg)
- This will help remove any moisture or contaminants from inside your system that may have caused problems with performance earlier on
- After 10 minutes, turn off the pump again and close both valves on either end of your hoses, ensuring there is still good suction throughout both lines before moving onto step 5 below: 5
- Slowly open up one valve at a time while keeping an eye out for any increase in pressure or temperature within each line as this would indicate an issue with one of them being blocked or clogged somewhere along its length — if you observe this happening then shut down everything immediately and investigate further before continuing! 6 Once both valves have been opened fully, slowly start adding R134A refrigerant into each line until you reach approximately 80% capacity according to manufacturer’s specifications; keep checking pressure levels every few seconds during this process as well just in case something unexpected happens such as overfilling one side but not enough refrigerant going into another part due to some other type of blockage or restriction occurring elsewhere within its respective line(s)

How to Recover Refrigerant Without a Machine
Recovering refrigerant without a machine is possible but should be done with extreme caution. To do this, you will need to use a process called “open-loop recovery” which involves connecting the high and low side manifold valves directly to each other. This allows for the refrigerant gas to flow between both sides of the system without being compressed by a compressor.
It is important that all safety precautions are taken during this process as it can be very dangerous if not done properly and may cause serious injury or death.
