Dimensional Drawings

The second page of the document contains detailed dimensional drawings of the LMU243HV unit. These include various views such as top, front, side, and rear perspectives, along with a 3D representation. All dimensions are provided in inches, illustrating the physical size and layout of the outdoor unit, including connection ports and fan placement.

Notes

Acceptable operating voltage: 187V - 253V.
Piping lengths are equivalent.
Sound pressure levels are tested in an anechoic chamber under ISO Standard 3745.
All power / communication cable must be minimum 14 AWG, 4-conductor, stranded, shielded or unshielded wire, and must comply with applicable local and national codes. If shielded, the wire must be grounded to the chassis at the outdoor unit only.
Power wiring size must comply with the applicable local and national codes.
Capacity ratings are net at 0 ft. above sea level, with 0 ft. level difference between outdoor and indoor units, and specific refrigerant pipe lengths. All capacities are net with a combination ratio between 95 - 105%.
Installation must follow instructions in the applicable LG installation manual.
Refer to the Combination Data Manual for combination capacity tables.
See the Performance Data Manual for sensible and latent capacities.
