IImmppoorrttaanntt:: Installation of this unit shall be made inaccordance with the National Electric Code,NFPA No. 90A and 90B, and any other localcodes or utilities requirements.

IImmppoorrttaanntt:: Air handlers do not require repositioning ofthe coil or drain pan for upflow orhorizontal left applications. See thedownflow and horizontal right installationsections for application instructions.

NNoottee:: Air handlers have been evaluated in accordancewith the Code of Federal Regulations, ChapterXX, Part 3280 or the equivalent. “SUITABLE FORMOBILE HOME USE.”

NNoottee:: Condensation may occur on the surface of the airhandler when installed in an unconditionedspace. When units are installed in unconditionedspaces, verify that all electrical and refrigerantline penetrations on the air handler are sealedcompletely.

NNoottee:: The manufacturer recommends installing ONLYA.H.R.I approved, matched indoor and outdoorsystems. Some of the benefits of installingapproved matched indoor and outdoor splitsystems are maximum efficiency, optimumperformance, and the best overall systemreliability.
