LG 42,000 BTU 21.1 SEER2 Tri Zone Wall Mounted Ductless Mini Split Heat Pump System 9+9+24 R32 Refrigerant | KUMXB481A-KNUAB091A-KNUAB091A-KNMAB241A-PMBD3630ZR

Description

Overview

This LG Multi F MAX heat pump system pairs the KUMXB481A outdoor unit with 3 LG Multi F standard wall-mounted indoor units for tri-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 KUMXB481A multi-zone outdoor unit (up to 8 indoor units through branch distribution units, LG R1 twin rotary inverter compressor)
2 x KNUAB091A (9,000 BTU LG Multi F standard wall-mounted indoor unit)
1 x KNMAB241A (24,000 BTU LG Multi F standard wall-mounted indoor unit)
1 x PMBD3630ZR 3-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 21.1 SEER2, 13.3 EER2 and 9.6 HSPF2, with a rated cooling capacity of 42,000 BTU/h and a rated heating capacity of 47,340 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

These indoor units have built-in Wi-Fi for control through the LG ThinQ app. Each indoor unit includes a wireless remote controller.

Use Case Fit

Wall-mounted indoor units suit bedrooms, offices, living rooms and additions where a high wall location is available. 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.
