MAINTENANCE
Preventative maintenance procedures are necessary to maintain optimum
performance.
CHECKING THE AIR FILTER
The air filter is used to minimize the accumulation of dirt inside the unit for
maximum operating efficiency. An excessively dirty filter could reduce
machine air pressure and allow dust to accumulate in the unit. Check the air
filter as needed based on surrounding environmental conditions.
To Check the Air Filter:
1. Remove the filter cover located on the back of the unit to gain access
to the filter. Filter cover can be removed by grabbing two sides and
pulling.
NOTE: Unit does not have to be
powered off to check the air
filter.

Checking Air Filter
2. A mesh screen and filter cover are contained within the filter cover.
Separate the mesh screen from the filter. Check filter for dirt
consistency.
3. Minor dirt accumulation can be removed by cleaning the filter with mild
soap and water.
IMPORTANT: Filter should be completely dry before installing.
– If the filter is significantly soiled that it appears to inhibit air flow, it
must be replaced.
