... NOTE ...
As refrigerant is processed by the TC670, 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 TC670 it may
not all be seen in the 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.
2. Press top (ON) of rocker switch marked RECOVER/RECYCLE.
The TC670 will recover and recycle refrigerant into the Charging Cylinder. Observe the liquid
refrigerant level rise in the Charging Cylinder Sight Glass and when at approximately 3 lbs.
close the 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 TC670 to continue running until the Low Side Gauge shows a vacuum. This will
evacuate the Blue Hose.
3. Press bottom (OFF) of rocker switch marked RECOVER/RECYCLE.
