Maintenance
8 cm cooling fan with filter
Periodic fan and filter cleaning is required to insure long life and reliability.
- The time period between cleanings depends on the quality of the environment.
- Under normal duty use, Delta recommends smart fans and filters be cleaned
every 6 months
- For very dusty locations, it may be necessary to clean the fans and filters
quarterly or monthly.
The cooling fans feature modular designs that make their removal for cleaning
or replacement a simple task. As a result, the replacement of fans is also smart.
