If the RHS980 has the optional refrigerant identifier
installed, the screen to the left and next 6 subsequent
screens will appear.
Inspect the identifier hose for traces of oil
contamination. If oil is present in the hose, remove the

Inspect the id filter, sample hose and coupler filter prior

free of oil contamination. See REFRIGERANT
IDENTIFIER MAINTENANCE section for more
information.

how much oil has been removed from the system
during the service.
