Flushing of the hoses is required if the next vehicle to be serviced contains a di󰀨erent type of A/C system oil than the
previous vehicle serviced. During the Hose Flush Process, the compressor and tank liquid solenoid are 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 ush hoses or residual oils.
