RECOVER - RECYCLE
To Recover - Recycle, refer to the above illustration and follow these steps:
1. Attach the Red and Blue Hoses to the A/C system per the manufacturer's instructions.
2. Open the High and Low Gauge Valves.
3. Open the Red and Blue Hose Valves.
4. Press the top (ON) of the rocker switch marked POWER.
5. Press the top (ON) of the rocker switch marked RECOVER-RECYCLE.
The TC670RR will automatically recover and recycle refrigerant from the A/C System until
a vacuum is sensed. This vacuum level can be seen on the Low Side Gauge.
Note: A small quantity of Liquid refrigerant will probably still remain in the A/C System. This
can be detected by observing an increasing pressure reading on the Low Pressure
Gauge. As pressure increases to a preset level, the TC670RR will automatically cycle
on and off to continue recovering refrigerant. Allow this automatic sequence to repeat
until the vacuum level remains constant for at least 2 minutes.
6. Close the Red and Blue Hose Valves.
7. Close the High and Low Gauge Valves.
8. Press the bottom (OFF) of the rocker switch marked RECOVER-RECYCLE.
9. Press the bottom (OFF) of the rocker switch marked POWER.
Note: The PURGE REQUIRED OR CYLINDER FULL light will illuminate if either the
Recovery Cylinder has filled to capacity or the pressure on the Purge Gauge
approaches 450 psig.
