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

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.
