In addition to the service information presented in the Cyclone DuraDrain

™

 trailer water separator Service Data

Sheet SD-08-2402 dated 8/2004, it is recommended that the following service intervals be followed to ensure
proper maintenance.  Also included are additional guidelines for troubleshooting air leakage in the Cyclone
DuraDrain

™

 trailer water separator.

Service intervals are dependent on specific environmental and operational factors that control the amount of
contamination removed by the Cyclone DuraDrain

™

 unit.  Experience should be used to determine how frequently

the unit must be serviced.  As a recommended minimum, every 12 months, 100,000 miles or 3,600 operating
hours, perform the Operational and Leakage Tests.  As indicated in the Service Data Sheet, inspect the
Cyclone DuraDrain

™

 unit for unrestricted airflow and blockage from debris collection.  Remove the purge nut

and service according to the “Disassembly and Cleaning” instructions.

This is the recommended troubleshooting procedure should an audible air leak be detected from the Cyclone
DuraDrain

™

 trailer water separator.  Be sure to review and follow all safety guidelines in the Service Data Sheet

before servicing the DuraDrain

™

 trailer water separator.

All servicing can be done without disconnecting the air lines and without removing the Cyclone DuraDrain

™

trailer water separator body.  All servicing is done to the removable hex purge nut located on the bottom.  See
the illustration below.
