To Recover/Recycle, refer to Figure 2 and follow these steps:
1. Attach Red and Blue Hoses to the A/C system per the vehicle manufacturer's instructions.
Note For R134a Machines
Field Service Couplings on the ends of Service Hoses are of a special design.
The valves have LEFT HAND threads which makes operation opposite to that of others.
To Close... Turn Counter-clockwise
To Open... Turn Clockwise
The valves MUST BE CLOSED before connecting or disconnecting Field Service Couplings.
2. Open High and Low Gauge Valves.
3. Open Red and Blue Hose Valves.

The TC670E 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.
