Ecotechnics SUN ECK TWIN 12 User Manual page 32

The machine checks whether or not there is air in the tank and, if necessary, purges the non-
condensable gas; The machine will automatically discharge any non-condensable gas.
Allowing the machine to fully complete the procedure will reduce the risk of return flows, which
may cause excessive non-condensable gas to be recharged into the air conditioning system. If
any residual refrigerant in the A/C system should increase in pressure during this phase, the
machine will automatically begin recovering the refrigerant.
Completed the recovery phase, the machine automatically goes on to running the vacuum
phase for the preset time:
At the end of this phase, the machine will test for leaks in the A/C system:
(WARNING! If vacuum time < 15 minutes this test is not reliable). If leaks are found, the
machine will stop automatically and display the A/C SYSTEM LEAKS alarm.
Detection of micro-leaks is not guaranteed.
Upon completion of the vacuum phase, new oil will be automatically reintegrated: the volume
will be equal to that of the used oil discharged or to the volume set by the operator.
