Cleaning

NOTE: If the extracted refrigerant is heavily contaminated, It must be pumped through the filter systems several times. The state of cleaning can be seen at the moisture indicator (14).

1. Open the shut-off valve for the filling cylinder (22).
2. Switch on the service unit. The green pilot lamp lights up.
3. After cleaning the refrigerant (state visible at the moisture indicator), close the shut-off valve.

NOTE: The unit switches off automatically when all refrigerant has been pumped into the filling cylinder (red pilot lamp lights up). The pressure then increases in the filling cylinder.
