MAINTENANCE

Filters must be cleaned or replaced as often as necessary to assure good airflow and filtering action.

To remove filters through the sides of the unit, remove either the solid side panel on the piping end, or the larger side panel on the end opposite the piping.

To remove the filters from the front of the unit, loosen 2 screws and raise the top filter retainer. The upper filters can

be lifted over the center filter lip. Three wing nuts are pro- vided under the center filter retainer. Remove these and a part of the center filter support, giving access to the bottom fil- ters.

Drain pan(s) should be inspected regularly to assure proper drainage.

The evaporator blower bearings and blower motor bearings are permanently lubricated.
