I am about to start a retrofit of a 23xl with 2-120ton turbocors. This will be a r-22 conversion to 134a. My question is, is there a problem with leaving the float in as a metering device instead of introducing a exv. After looking over manufactures specs I cannot determine the issue with usinig the high side float regaurdless of the refrigerant it is 134a or 22. If there are any other tips they would be apprieciated. Thanks
