Description
Overview
This LG Multi F MAX heat pump system pairs the KUMXB601A outdoor unit with 4 LG 2x2 4-way ceiling cassette indoor units for quad-zone heating and cooling. Every indoor unit in this system is the same style, so each room gets matching appearance, airflow and controls. The system runs on 208/230V, 1-phase, 60 Hz power and uses R-32 refrigerant.
What Is Included
- 1 x KUMXB601A multi-zone outdoor unit (up to 8 indoor units through branch distribution units, LG R1 twin rotary inverter compressor)
- 2 x KNUDB091A (9,000 BTU LG 2x2 4-way ceiling cassette indoor unit)
- 2 x KNUDB121A (12,000 BTU LG 2x2 4-way ceiling cassette indoor unit)
- 4 x PT-QAGW0 cassette grille panel (one per cassette)
- 1 x PMBD3641ZR 4-port branch distribution unit
Performance
LG rates Multi F MAX systems by total connected indoor capacity. At 42,000 BTU/h connected (non-ducted), this system is rated at 21.5 SEER2, 13.8 EER2 and 10.5 HSPF2, with a rated cooling capacity of 42,000 BTU/h and a rated heating capacity of 48,000 BTU/h. Heating operation is rated down to -4 F outdoor temperature (wet bulb) and cooling operation from 14 F to 118 F.
Comfort and Noise
Each zone has its own indoor unit and set point, so occupied rooms can be conditioned independently while unused rooms stay idle. The inverter compressor adjusts its speed to match the load, which holds temperatures steadily and reduces on/off cycling.
Smart Features
Wi-Fi control through the LG ThinQ app is available with the optional PWFMDD200 Wi-Fi module. Each indoor unit includes a wireless remote controller.
Use Case Fit
2x2 ceiling cassettes fit standard drop-ceiling grids and spread air in four directions, which suits kitchens, open living areas and offices. A condensate pump is built in. Confirm room loads, line set lengths and electrical requirements before ordering. Professional installation is recommended.
Value and Reliability
Bundling the outdoor unit with matched indoor units and branch distribution units in one product simplifies ordering. Warranty: 7 Years Compressor & 5 Years Parts | Registration Required within 60 Days of Purchase.
