To Charge Refrigerant, refer to Figure 5 and follow these steps:
1. Perform Hose Evacuation described previously.
2. Connect Red Hose to the A/C System high side per the vehicle manufacturer's instructions. Do

3. Press top (ON) of rocker switch marked CHARGE/HIGH SIDE. The Charge Cylinder will now
be heating to develop pressure for charging.
4. Open High Gauge Valve. The Low Gauge Valve and both Hose Valves should be closed.

tenths of a pound for setting the TC670 charge indicator.
The following will determine where to set the indicator prior to starting the charge mode:
