Maintenance

Provided it is correctly installed in an appropriate location and is not abused, the 

charger will require little maintenance. The only requirement is to monitor the air inlet 

filter at the front of the charger for dirt accumulation. The charger modules internal to 

the charger housing require a good supply of cooling air during the charge cycle and 

a blocked filter will affect the cooling. A blocked filter could lead to the charger turning 

down its maximum output to prevent overheating of the charger modules. An extremely 

blocked filter could cause longer charge times, inability to charge the battery correctly 

or premature wear of the charger modules.

Service Interval

The recommended service interval is 6 months but this will vary depending on the 

location of the charger and the number of charge cycles performed. The fans in the 

charger modules only run during charging and are speed controlled. If the charger 

output is small the fans will only be turning slowly. At full power there is a considerable 

requirement for cooling air and the fans will be working hard with considerable hot 

air being exhausted from the rear of the charger. The exhaust air from the rear of the 

charger should never be restricted. The intermittent nature of the fans results in a long 

fan service with no scheduled replacement of fans being required.

Intake Filter

The filter material is an electrostatic polypropylene type that is easy to clean with 

compressed air to blow out any accumulated dirt and dust. Before attempting to clean 

the filter it is necessary to remove it from the housing by unscrewing the two captive 

screws and unhinging the filter from the housing. The electrostatic filters provide a 

good compromise between filtering and clogging, but a small quantity of dust will enter 

the charger modules during normal operation. A small quantity of dust in the charger 

modules will generally not cause problems, however excessive accumulation or where 

the material ingested is corrosive, conductive or wet will cause issues, resulting in 

premature wear of the charger modules.

Removing 

the filter 

from the 

housing.

1. Unscrew the 2x

captive screws and 

unhinge the filter 

from the housing.

2. Blow out any dirt

& dust buildup with 

compressed air to 

clean the filter.
