How to Recover R-134a Refrigerant from an Automobile using Mastercool 69000 + 69500 Equipment

Описание: In this forth and final video of the air conditioning series we combine all the previous components introduced for our new R134a refrigerant recovery machine system into an actual recovery operation. The particular brand and model equipment shown is the prosumer / entry level shop gear Mastercool 69000 recovery machine paired with the Mastercool 69500 RecoveryMate accessory which provides Polyalkylene Glycol (PAG) oil separation, R134a refrigerant filtering and drying, and R-134a refrigerant embedded moisture detection. However, the basic procedures and AC information shown would be applicable to most other R-134a refrigerant recovery machines from other brands.

We cover in this video:
Hookup of R134a service port couplers and vacuum pump ball valve
Recovery of the R134a refrigerant charge in the vehicle
Purging the recovery machine or residual R134a refrigerant
Performing a post-repair vacuum draw down on the vehicle AC system

If you are looking for a nitrogen cylinder regulator, I have had good luck with the imported model BETOOLL one you saw in the video: https://amzn.to/3tFCieG You have to add a 1/2" ACME hose adapter to it and I used a Mastercool 82634 (with integral Schrader valve) that you can find at https://amzn.to/2PhuLUh or https://ebay.us/mV5fnE
