HOSE FLUSH PROCESS
Flushing of the hoses is required if the next vehicle to be serviced contains a different type of A/C system oil than the
previous vehicle serviced. During the Hose Flush Process, the compressor is activated. The high side and low side
charge, high side and low side inlet and recover solenoids are intermittently activated in a charge/recover process
to flush hoses or residual oils.
