1) Refrigerant currently recovered from the vehicle
2) Refrigerant pressure in the vehicle
In order to assure a perfect recovery and oil separation, the unit modulates the gas flow in relation to its
pressure. The ecovery cycles may therefore be alternated by intervals. The operation is followed by a
waiting period to check for any gas residuals in the system. The length of this test tim can be set in the
OPTIONS
menu. The unit then drains any oil recovered during the recovery phase.
