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 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. See this bulletin for further detail.
