Notes:

1. Acceptable operating voltage: 187V ‐ 253V.
2. Piping lengths are equivalent.
3. 180.4 ft. of Main Piping + 49.2 ft. of Branch Piping.
4. 49.2 ft. of Main Piping + 131.2 of Branch Piping.
5. At least one branch distribution (BD) unit is required for system operation; a maximum of two can be installed per ODU with the use of a Y‐branch accessory  (PMBL5620).
6. Sound pressure levels are tested in an anechoic chamber under ISO Standard 3745.
7. All power/communication cables to be a minimum of 14 AWG from the ODU to the BD unit, and 14 AWG from the BD unit to the IDU.
8. All power/communication cables to be 4‐conductor, stranded, shielded, or un-shielded, and must comply with applicable local and national codes. If shielded, the wire must be grounded to the chassis at the ODU only.
9. Power wiring size must comply with the applicable local and national codes.
10. See the Engineering Manual Capacity Tables for ODU sensible and latent capacities.
11. See the Engineering Manual Combination Tables for allocation of ODU-rated capacity to each connected IDU when all are calling for full capacity. Allocation percentages should be applied to ODU capacity at design conditions.
12. This data is rated 0 ft. above sea level, with 115 ft. of refrigerant line, and a 0 ft. level difference between ODU and IDUs. All capacities are net with a combined ratio between 95 ‐ 105%.
13. Must follow installation instructions in the applicable LG installation manual.
14. See the Engineering Manual Capacity Tables for ODU capacity at design conditions.
15. Installation of an optional Low Ambient Wind Baffle Kit will allow operation down to ‐4°F in cooling mode.

Notes:

1. The unit must be installed in compliance with the installation manual.
2. The unit must be grounded in accordance with local or state regulations and applicable national codes.
3. All field-supplied electrical components and materials must comply with local, state, and national codes.
4. Electrical characteristics must be considered for electrical work and design. The capacity of the power cable and circuit breaker for the outdoor unit must follow local, state, national, and manufacturer requirements.

Example: an outdoor unit with eight (8) indoor units and two (2) branch distribution units connected.
ODU: Outdoor Unit.
IDU: Indoor Unit.
BDU: Branch Distribution Unit(s).
A: Main Pipe.
B: Branch Pipe (Branch Distribution Unit[s] to Indoor Unit[s]).
