... NOTE ...
As refrigerant is processed by the RRC770, temperature variations
can cause vapor to change to liquid which may temporarily settle
in various internal components.
If a known amount of refrigerant has been introduced into the
RRC770 it may not all be seen in the Internal Charging Cylinder
Sight Glass.
This is normal and nothing to be concerned about. Refrigerant has
not been lost.
The sight glass does not indicate the amount of refrigerant
recovered. It is only accurate for determining the amount of
refrigerant charged out to the vehicle A/C System while in the
Charge Mode of operation.
3.
Set Mode Selector to RECYCLE.
4. Turn Main Power Switch to RECYCLE.
The Compressor-On Light will illuminate and the RRC770 will recover and recycle
refrigerant into the Internal
Cylinder. Observe the liquid refrigerant level rise in the
Internal Cylinder Sight Glass and when
at
approximately 3 lbs. close the Vapor
Valve on the refrigerant cylinder.
HINT:
Heating of the cylinder of refrigerant with an RTI Heat Belt (P/N 026-
80092-00) will speed the recovery process.
Allow the RRC770 to continue running until the Compressor-On Light goes off. This
will
evacuate the Yellow Hose.
