    Why.

    different hoses? Why flush the manifold? With some of the R22 replacements (HI,Med and/or LO temp) it is RECOMMENDED to add some mineral oil to the system to aid in oil return. Some say NEVER EVER cross contaminate the oils/freons.In the beginning of this oil/Freon thing when converting over to a "new" Freon/oil we were allowed to have 90-95% of POE and 5-10% mineral oil. Everything was good at those ratios.  Gotta go back to work. I carry 8 kinds of Freon on board , so I guess I need lots more manifolds and evacuation manifolds also. Damn you!!!!!!!!!!!!!!!!!!!
