Maintenance
At least every 3 months:
The filters should be cleaned and renewed when needed. Usually the filters need to be renewed
once every 3 month. The filter guard in the CTS 602 control can be used in order to make sure that
the filters are checked. The filters can be cleaned by vacuuming or shaking them.
Changing filters:
1. Loosen screws
2. Remove the filter hatch
3. Pull out the two filter frames for change/vacuuming
