DC FAST CHARGER MAINTENANCE
SERVICE INFORMATION
The DC Fast Charger requires periodic air filter maintenance.
If the air filters are not serviced and become restricted, the DC Fast Charger will set DTC
0x051E Thermostat Error (Charger malfunction) and suspend operation until the restriction
is cleared and the power to the DC Fast Charger is cycled.
The DC Fast Charger has five air filters that need to be serviced based on the surrounding
environmental conditions where the charger has been installed. The necessary service
intervals can be determined initially with frequent periodic monitoring, since every
installation site will be different and may result in different servicing needs. Seasonal issues
such as pollen, leaves, or random debris may also affect air filter performance. Of the five
filters, three can be serviced by a qualified LEAF® technician. Those air filters are the FAN
2 air filters (rear base external air filter and fine particulate air filter), and the FANS 7, 8, 9
air filter (bottom of the heat sink inlet filter). The remaining two air filters must be
serviced by a licensed electrician.
The air filters should all be inspected 30 days after the unit is first put into service, to
determine the levels of individual restriction.
•
Any air filters found to be heavily restricted during the initial 30 day inspection should
be serviced at a monthly or bi-monthly interval.
•
If none of the air filters are heavily restricted, they should be serviced and then
rechecked at 90 day intervals (some air filters may require less maintenance than
others).
The Internal air filter may only need annual replacement unless the site is extremely dusty.
It is the only air filter that requires the removal of the external charger casing. This should
only be performed by a licensed electrician. For warranty and maintenance service
contact AeroVironment, Inc. 1610 S Magnolia Ave, Monrovia, CA 91016. 1-888-833-2148.
The fine particulate air filter will require the most frequent service. Depending upon
environmental conditions, it may become restricted in anywhere from a few weeks to a
year.

properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job

does. See your Nissan dealer to determine if this applies.

5. To Clean the FAN 2 fine particulate air filter:
a. Lay the FAN 2 fine particulate air filter flat in a sink and gently wet with a mixture of
warm water and mild dishwashing soap.
b. While the air filter remains flat, gently work soapy water mixture into the air filter to
loosen dirt/debris.
c. Turn the FAN 2 fine particulate air filter over and continue to gently work in the
soapy water mixture to further loosen any remaining dirt/debris.
d. Rinse the soap from the FAN 2 fine particulate air filter.
e. Lay flat the freshly cleaned FAN 2 fine particulate air filter on a paper towel, place a
second paper towel on top of the air filter, and then press dry.
FAN 2 fine particulate
air filter must be
completely tucked into
the frame around the
edges
Use a finesse tool
to work the FAN 2
fine particulate air
filter back into the
frame
