Features
- Precision Temperature Control Technology
- The outdoor condenser is equipped with inverter technology and an electronic linear expansion valve. These components improve temperature accuracy and system efficiency through precise adjustments of both compressor speed and refrigerant flow.
- Hot-Start
- Mitsubishi's Hot-Start technology prevents cold drafts by delaying fan operation until the heat exchanger has warmed up.
- Vane Control
- Optimal air flow can be achieved with the MLZ-KP thanks to the vane control option. This function provides access to an Auto mode and a Swing mode.
- Condensate Removal System
- The MLZ-KP contains an internal drain mechanism capable of lifting condensate 19-11/16". This simplifies installation and prevents condensate overflow, which can damage or destroy your property.
- Serviceability
- The MLZ-KP is designed to fit between standard 16" joists and be serviced from below, making installation and maintenance easier than ever.
- Dehumidification
- When the indoor unit runs in Dry mode, the coil's temperature stays just below the dew point of the return air, removing unwanted moisture. This improves your comfort and reduces the chance of mold growth and other property damage in the room.
- H2i Technology
- H2i Hyper Heat performance offers 100% heating capacity at 5 degrees and 75% heating capacity at -13 degrees Fahrenheit.
- Integrated Base Pan Heater
- Factory-installed base pan heater in the drain pan. This prevents condensate from freezing and damaging the unit in frigid climates.
- Recommended line set sizes for indoor unit connectivity:
- MLZ-KP09NA2: 1/4" x 3/8" Line Set
- MLZ-KP12NA2: 1/4" x 3/8" Line Set (Qty 2)
- MLZ-KP18NA2: 1/4" x 1/2" Line Set
- Recommended line set sizes for branch box connectivity:
- MXZ-SM48NAMHZ2: 3/8" x 5/8" Line Set
- (1) Mitsubishi - 48k BTU - M-Series Smart Multi H2i Outdoor Condenser - For 2-8 Zones (MXZ-SM48NAMHZ2)
- (1) Mitsubishi - 18k BTU - M-Series One-Way Ceiling Cassette without Grille - For Multi or Single-Zone (MLZ-KP18NA2)
- (2) Mitsubishi - 12k BTU - M-Series One-Way Ceiling Cassette without Grille - For Multi or Single-Zone (MLZ-KP12NA2)
- (1) Mitsubishi - 9k BTU - M-Series One-Way Ceiling Cassette without Grille - For Multi or Single-Zone (MLZ-KP09NA2)
- (1) Mitsubishi M-Series - 5 Ports - Branch Box (PAC-MKA53BC)
- (4) Mitsubishi MLP-444W Ceiling Cassette Grille For Mitsubishi MLZ-KP Mini Split Units (MLP-444W)
- Line Set - This double insulated tubing transfers refrigerant efficiently between your outdoor condenser and indoor units.
- Disconnect Box & Electrical Whip Kit - The Disconnect Box & Whip Kit provides a safe and simple way to connect your outdoor condenser to your fuse box.
- Connecting Wire - This durable, insulated wire provides power to your indoor units from your outdoor condenser.
- Outdoor Condenser Plastic Pad or Wall Bracket - We recommend outdoor condensers should not be placed directly on the ground. An outdoor condenser pad or wall bracket will provide a stable way to mount your condenser free from obstructions and debris. Adding these accessories to your order will provide a complete, ready-to-install mini split system. All Mini Split Systems require one Primary Mini Split Installation Kit. You will need a Secondary Installation Kit for each additional indoor unit.
Mitsubishi's dedication to new technology means that multi-zone mini split systems are now a year-round comfort solution for homes in freezing climates. This low ambient system uses a Hyper-Heating H2i MXZ-SM48NAMHZ2 outdoor condenser to provide efficient cooling and subzero heating through four advanced MLZ-KP ceiling cassette indoor units. Four wireless remote controllers guarantee convenient comfort by allowing you to control the temperature in individual rooms. An MXZ multi-room system is an excellent choice for supplementing capacity to a current system, conditioning newly furnished spaces, or new additions and replacing a system within a home. With multiple operating modes and multiple fan speeds, this is a system that fits the needs of nearly any home.

The U.S Department of Energy has raised the minimum rating requirements starting in 2023 that include updated testing conditions and metrics to better reflect real-world conditions. SEER2 (Seasonal Energy Efficiency Ratio) is a measurement of cooling efficiency over a typical cooling season. It is useful for comparing energy efficiency of cooling systems. The higher the SEER2, the more energy efficient the system.
