10. When mounting the service access panel, louvered or non-louvered, the installing contractor
must provide a frame in order to connect the enclosure assembly to the service access panel. This is
required to obtain an airtight seal for the return air. Ensure that the material used for the frame
adheres to national codes and / or local codes and regulations. Care must be taken when installing
the service access panel to ensure the opening of the hinged service panel.

11. Filters are not supplied with the fan coil unit or the service access panel. The filter(s) must be
supplied by the installing contractor. If a louvered service access panel is used the filter will mount
on the under side of the hinged access panel. If the optional return air cutout is used it is
recommended that a return air filter grille be used that has the same surface area as the
recommended filter sizes.
