Recovery is the removal of refrigerant from a system to either store and send in for recycling or to reintroduce back into the same system.

Here are some top tips –

  • Make sure your tank is empty and evacuated to 300 microns if you plan to return the refrigerant back into the system.
  • Never mix refrigerants.
  • Purge hoses before recovery.
  • Use a flare line drier on the inlet of the machine to increase the life of the machine and to filter and dry the refrigerant. These must be replaced regularly.
  • When recovering into a tank using the standard method invert the tank and pump into the vapor port on the tank.
  • Remove Schrader cores before recovery for faster recovery and a cooler tank.
  • Use larger gauge hoses with no core depressors for faster recovery.
  • Check Recovery machine inlet screens regularly and clean or replace as needed.
  • Some machines require oil to be run through the machine from time to time. Read manufacturer specifications.
  • If your tank becomes hot you can either place it in a bucket of water or run water over the tank.
  • Do not leave refrigerant in your machine during storage. If your machine has a purge mode make sure to purge the refrigerant out of the condenser (see manufacturers specs on your machine).
  • Most HVAC systems holding under 200 lbs of refrigerant are not required to be pulled into a vacuum during recovery. See this chart from the EPA.
  • Weigh the refrigerant out and do not fill the tank to more than 80% of the REFRIGERANT capacity, not just the water capacity.
