At the halfway point of the filtration process, stop the procedure and change the filters on the machine.Note: Refer to "Oil Compartment Filtration Times for 204-7392 Filter Cart" and "Oil Compartment Filtration Times for 188-3242 Filter Cart", at the end of this document when a portable particle analyzer is not available.Note: Changing the filters halfway through the filtration process avoids opening the filter housing after the system has been cleaned. The housing becomes an inlet for contamination if the filter housing is opened after the filtration process is complete. The new filters can remain in place until the next scheduled filter replacement.
Operate the filter cart until the portable particle analyzer indicates that the oil has reached an ISO level of at least 18/15. The final ISO should be recorded before the machine is returned to the field.
When the target ISO level has been met, close the air supply valve (8) and disconnect the air supply hose (9). Refer to Illustration 8.
