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.
