Outdoor Unit Installation DrawingsInstallation Guidelines• Where a wall or other obstacle is in the path of outdoor unit’s intake or exhaust airflow, follow theinstallation guidelines below.• For any of the below installation patterns, the wall height on the exhaust side should be 47-1/4 inch(1200mm) or less.* Be sure to add the proper amount of additional refrigerant.Failure to do so may result in reduced performance.Max. allowable heightMax. allowable length 98.4ft (30m)65.6ft (20m)Model 30/36 classLiquid pipeGas pipeO.D. 3/8 inch (9.5mm)O.D. 5/8 inch (15.9mm)0.55oz/ft(50g/m)Additional refrigerantrequired for refrigerantpipe exceeding 32ft(10m) in length.Min. allowable length 6.6ft (2m)More than 1-15/16”(50mm)Morethan3-15/16”(100mm)More than 13-3/4” (350mm)47-1/4”(1200mm)or lessMore than 1-15/16”(50mm)More than13-3/4”(350mm)Wrap the insulationpipe with the finishingtape from bottom to top.Allow 11-13/16 inch (300mm)of work space below theceiling surface.9-7/8” (250mm) from wall Allow space for pipingand electrical servicing.Right side plate13-5/8”(345mm)Clamping materialInsulation tubeBottom frameTapeAlso insulate the connection on the outdoor unit.Use tape or insulating material on all connectionsto prevent air from getting in between the copperpiping and the insulation tube.Be sure to do this if the outdoor unit is installedabove.(Foot bolt-holecentres)(Foot bolt-hole centres)24-7/16”(620mm)Level mounting base(available separately)If there is the danger of the unit fallingor overturning, fix the unit withfoundation bolts, or with wire or othermeans.If the location does not have gooddrainage, place the unit on a levelmounting base (or a plastic pedestal).Install the outdoor unit in a levelposition. Failure to do so may result inwater leakage or accumulation.More than 3-15/16”(100mm)Side viewWall facing one sideTop viewWalls facing two sidesTop viewMore than 3-15/16”(100mm)More than 13-3/4”(350mm)More than 1-15/16”(50mm)Walls facing three sidesCAUTIONSet the piping lengthfrom 6.6ft (2m) to 98.4ft (30m).
