Purge Chart
5. Determine the room temperature. A Pocket
Thermometer is convenient for this
measurement.
6. Locate the pressure (PSIG) corresponding to this
room temperature (
0 F) in Table at right.
If Pressure Gauge indicates higher than that
determined from the table...
SLIGHTLY & SLOWLY open Valve on
Yellow Service Hose connected to INLET of
TX600 until the Pressure Gauge pressure equals
that shown in the table. Any Non-condensable
Gas will be vented through the Oil Drain Valve.
NOTE...
A copy of the Temperature/Pressure Table is
located on the rear of the TX600 for easy
reference.
7. Close the Oil Drain Valve.
8. Open Valve on Yellow Service Hose connected to
the INLET of TX600 for approximately 5 seconds;
then close. This permits any residual Non-
condensable Gas to be recirculated for reprocessing
during the next recycle procedure.
9. Close VAPOR Valve on Refrigerant Cylinder.
Non-condensable Gas has now been removed and the
refrigerant is ready for charging back into an A/C
System.
CAUTION...
The preceding Recycling and Purge Procedures allow
the Yellow Service Hoses to remain permanently
connected to the TX600. Disconnecting either hose
from the TX600 may vent refrigerant unnecessarily or
introduce air into the system and should be avoided.
The Yellow Service Hoses should remain connected to
the TX600 unless repair or transport is required.
