OIL DRAIN & RAPID AIR PURGE SYSTEM PROCEDURE
Oil and Non-condensable Gas (Air) are separated from the recovered refrigerant and MUST be
removed following EACH recycling procedure as follows:
1. After completing the Recycle Mode, reconnect TX600 as shown in Figure II.
2. Open VAPOR Valve on Refrigerant Cylinder.
3. SLIGHTLY open Valve on Yellow Service Hose connected to INLET of TX600 until
reading of Pressure Gauge on Refrigerant Cylinder drops approximately 2 PSIG and then
immediately close the Valve.
4. SLOWLY open Oil Drain on the front of TX600 to vent Non-condensable Gas and drain
any oil which may have been removed from the A/C System. A plastic cup is provided with
the TX600 to collect and measure the oil.
Unless the A/C System had previously been overfilled, the TX600 will not remove enough
oil to make replenishment necessary.
Leave Oil Drain Valve open.
