Procedure for Clearing TX200 between Refrigerants
The TX200 can be used to recover many different refrigerants. If the recovered refrigerants
are to be recycled and/or reused, it is necessary to avoid mixing the different refrigerants.
The TX200 will always contain a small amount of refrigerant within the internal components
after each recovery procedure. This refrigerant must be cleared before recovering a
different refrigerant. The following simple procedure can be performed to clear the
refrigerant from all internal components of the TX200.
1) Connect the TX200 as shown above.
2) Open valve on ERC cylinder and valve on connecting hose. Close valve on inlet hose.
3) Turn power on. Press and hold DEEP VACUUM switch for one minute. This will
remove any refrigerant from the inlet hose and EDF filter.
4) Turn power off, close all valves and disconnect hose and OFP cord from the ERC
cylinder. This cylinder should be marked with the refrigerant type and stored for later
use.
5) Connect an empty DOT cylinder to the TX200 and a vacuum pump as shown below.
6) Open both valves on the DOT cylinder. Do not open the valve on the hose connected
between the DOT cylinder and the TX200.
7) Turn the vacuum pump on and let it run for ten minutes to place the DOT cylinder in
a vacuum.
8) Close the valve of the DOT cylinder connected to the vacuum pump. Disconnect the
vacuum pump from the DOT cylinder.
9) Open the valve on the hose connected between the DOT cylinder and the TX200. Any
refrigerant in the TX200 will be pulled into the DOT cylinder.
10) Close all valves and disconnect the DOT cylinder from the TX200.
11) All refrigerant has been removed from the TX200 which can now be used to recover
another type of refrigerant.
