How LG Multi F systems work
LG heat pump systems consist of three basic components: An inverter (variable speed) outdoor heat pump,
stylish and quiet indoor units, and a conduit with piping and wiring to connect the outdoor unit to each indoor
unit. Multiple indoor units allow precise indoor temperature control throughout your home and provide the ability
to adjust the temperature in each area to meet your needs.

Note:
1. Rated capacity at 0 ft. above sea level with 25 ft. of refrigerant line and a 0 ft. level difference between outdoor and indoor unit.
2. Rated cooling capacity obtained with air entering the indoor unit at 80˚F dry bulb (DB) and 67˚F wet bulb (WB) and outdoor ambient conditions of 95˚F dry bulb (DB)
and 75˚F wet bulb (WB).
Rated heating capacity obtained with air entering the indoor unit at 70˚F dry bulb (DB) and 60˚F wet bulb (WB) and outdoor ambient conditions of 47˚F dry bulb (DB)
and 43˚F wet bulb (WB).
For capacity information, see engineering manual capacity tables. Capacities are based on connection of Non-Ducted indoor units.
3. All power/communication wiring minimum 4-conductor, stranded, shielded, and must comply with applicable local and national codes.
4. Due to our policy of innovation, some specications may be changed without notication.

Year-round comfort in
all areas of your home
Benets of LG Multi F systems:
LG Multi F whole-home comfort systems provide powerful, efcient heating and cooling with up to eight
indoor units operating off a single outdoor unit. In fact, most combinations are ENERGY STAR® Certied.
Individual room temperature control with low operating cost are at your ngertips with LG Multi F.
Installation is easy and does not require major renovations – the pipes connecting your outdoor unit to the
indoor units are small and easy to run throughout your house. Your contractor can usually install a whole-
home system in just a few days start-to-nish and adding an additional indoor unit down the road is simple
and cost-effective. Using three or more indoor units is more cost-effective and uses less space than installing
three individual single-zone systems.

With a larger outdoor unit, the cooling and heating capacity is increased with the 3-4
zone option. This may include additional indoor units in bedrooms, the den, sunroom,
or any other area not covered by a 2-3 zone option. Additionally, the LMU30CHV and
LMU36CHV are compatible with our 24,000 Btu/h vertical air handler and high static
ducted indoor units.
