Remove any shipping clips securing coil. 3, Remove complete coil/drain pan assembly. 4. Remove and discard horizontal drain pan from coil assembly. 5. Drill four 1/4-in. holes (2 on each side) in fan coil casing at dimples provided. (See Fig. 1.) 6. Secure coil brackets (provided in kit) to casing sides. (See Fig. l.) 7. Install support strap (provided in kit) across front of unit as follows: a. Position flange on each end of strap between coil bracket and casing insulation. (See Fig. 1.) b. Secure support strap ends m coil brackets. (See Fig. 1.) 8. Remove and discard 4 clips (on comers of coil) securing coil assembly to rails for upflow applications. 9. Remove and discard factory-shipped air seal and drain tube assembly. Install l-piece sheet metal air seal assembly provided with kit. 10. Tilt coil assembly back and slide angles (provided in kit) over each inside wall of condensate pan. Pop-riveted flange of angles should extend toward coil. (See Fig. 2.) 11. With fan coil in downflow position, slide coil assembly into unit. (See Fig. 3.) 12. Reinstall all panels. Align holes in panels with tubing and condensate connections. Casing was designed to allow 180 ° rotation of coil access panel and fitting panel. 13. Install 2 plugs that have been provided onto doors to seal unit.
