MAINTENANCE
The DPF system requires very little maintenance: cleaning or replacing the filter
element every 1000 hours of APU operation (or when notified by the system)
is all that is needed. All other maintenance items are related to the APU:
Fuel
Use low (or ultra low) sulfur diesel. ULSD is the default diesel formulation
available for commercial sale in the United States and Canada. It is also
permissible to use biodiesel up to B20 as long as it is low or ultra-low sulfur.
The presence of sulfur in the fuel does not damage the filter but leads to
ash buildup and may cause a need to clean the filter earlier than normally
expected.
Engine Oil
Oil changes and other APU maintenance should be performed on a schedule
according to the APU manual. The additional requirements are to use oil that
meets the API CJ-4 specification for low ash production and to be certain that
the engine is not over filled with oil. If the engine consumes more than 1
quart of oil in 200 hours of operation, then the engine needs to be serviced.
Continuing to operate the engine in this condition will cause the DPF to
plug prematurely.
