XII. Routine Maintenance
The ceiling assembly and the outside shroud can be cleaned with a damp cloth. When required a mild
detergent can be used.
There are two washable filters in the ceiling assembly, one behind each return air louvers. To access the
filters, pull on the tabs on the return air grilles. The filters should be washed in warm water or vacuumed
clean and replaced. The filters should be inspected once a month and cleaned as required. Note: If the unit
is operated in a dusty environment, the filters should be inspected and cleaned more frequently.
