How to fill the refrigerant after vacuum (Arabic version)

Step 1 - It is necessary to first evacuate the system of all refrigerant, by creating a vacuum with a vacuum pump. This process gives you a “clean slate” and also pulls out all extraneous air and moisture before the recharge.
Step 2 - After vacuum finished close the manifold gauge low side & high side, switch off vacuum and remove it
Step 3 - plug the middle gauge hose to cylinder, open gauge hose from top side to release the moisture & air from the line then close it.
Step 4 - Then put cylinder down side up and open high side manifold gauge, after coming high side approx 150 psig close the gauge
Step 5 - Run the unit & check the refrigerant status after running compressor in morning time low side make it 60 psig or at evening time make it 55 psig
