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.
