Condensate piping can be directed through the insidewall to an approved drain or straight outside.NOTE: The piping hole for condensate line must slope at aminimum pitch of 1/4 in. per foot to ensure proper drainage. Ifproper pitch cannot be achieved, install accessory condensatepump at this time.Step 3 — Mount Unit — Refer to Fig. 4 for clearancesand dimensions. Use mounting template included inside box tolocate mounting bolt holes, piping holes, electrical connec-tions, and accessory outdoor-air intake, if used.Select proper type of hardware from the guidelines below.See Fig. 5.WOODEN STRUCTURE — Install hanging bolts on asquare wooden piece placed over beams.NEWLY BUILT CONCRETE SLAB — Install hanging boltswith inserts, embedded bolts, etc.METAL STRUCTURE — Install hanging bolts utilizing anexisting angle or by installing a new support angle.PREVIOUSLY BUILT CONCRETE SLAB — Install hang-ing bolts with expansion anchor.TO MOUNT UNIT:1. Remove mounting bracket and reinstall the 2 hex-headbolts (factory-supplied) into each side of indoor unit asshown in Fig. 6. Allow approximately 3/8-in. spacebetween bolt head and unit.2. Determine installation position, paying particularattention to piping lengths, wiring connections, clear-ances, etc. See Fig. 3 for connection locations, Fig. 4for clearances, and Fig. 7 and 8 for bolt locations.3.
