Discharging the System

Print


NOTE
Use only a refrigerant tank that is designed for the charging station in use. The unit's overfill limitation mechanism is calibrated specifically for use with this tank. The tank's valves are also specifically for this unit.

  1. Attach the high-side hose with the quick disconnect coupler to the high-side fitting of the vehicle's A/C system.
  2.  
  3. Open the coupler valve after attachment.
  4.  
  5. Attach the low-side hose with the quick disconnect coupler to the low-side fitting of the vehicle's A/C system.
  6.  
  7. Open the coupler valve after attachment.
  8.  
  9. Check the high-side and the low-side gages on the unit's control panel in order to ensure that the A/C system has pressure. If there is no pressure, there is no refrigerant in the system to recover.
    WARNING
    If there is no refrigerant in the system, do not continue with the recovery operation. This will draw air into the recovery tank.

  10.  
  11. Open both the high-side and the low-side valves.
  12.  
  13. Open the gas and the liquid valves on the tank.
  14.  
  15. Drain any oil that may be in the oil separator.
  16.  
  17. Close the oil drain valve.
  18.  
  19. Plug the unit into the proper voltage outlet.
  20.  
  21. Turn ON the main power switch.
    NOTE
    Never reuse refrigerant oil. Damage to the A/C system may result. Dispose of the refrigerant oil properly.

  22.  
  23. Begin the recovery process. Refer to the manufacturer's instructions for the charging station in use. Important: Some A/C system PAG lubricating oil may be removed with the refrigerant during recovery. The amount of oil removed varies. A charging station separates the oil from the refrigerant and allows a means of determining how much oil was removed. Replace the same amount of oil when you recharge the system. Refer to the manufacturer's instructions for the charging station in use.
  24.  

Wait 5 minutes. Check the control panel low-side gage. If the A/C has maintained vacuum, the recovery is complete.

  1. Important: If the control indicator shows that the refrigerant tank is full during the recovery process and the unit shuts OFF, install an empty unit tank to store the refrigerant needed for steps later in the procedure. Do not use any other type of tank.
  2.  
  3. There is more refrigerant in the system if the low side gage pressure rises above zero. Recover the additional refrigerant. Repeat this step until the system maintains vacuum for 2 minutes.
