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
contamination hose section or replace the entire hose
assembly. See REFRIGERANT IDENTIFIER
MAINTENANCE section of manual.

If the results from the refrigerant identification show an
air percentage above 5%, this screen will appear.
Inspect the id filter, sample hose and coupler filter prior
to the next identification to ensure these devices are
free of oil contamination. See REFRIGERANT
IDENTIFIER MAINTENANCE section for more
information.
Adjust the O-Ring on the oil drain bottle to determine
how much oil has been removed from the system
during the service.
