state (liquid or vapour) of the system's refrigerant and
the presence of contamination in it
1. Disconnect the power supply to the A/Correfrigera-
tion system.
2. Connect the RG8.0 / RG4.0 to a mains power supply
that matches the voltage and frequency rating on the
RG8.0 / RG4.0.
3. Before making any hose connections, ensure that
A/C or refrigeration system service valves, manifold
gauge set valves, recovery unit control valves and
recovery tank valves are all in the closed position.
Also, make sure that the recovery / purge valve is in
the RECOVER position (pointed upwards). Refer to
