Features

    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-5C42NAHZ outdoor condenser to provide efficient cooling and subzero heating through three advanced MLZ-KP ceiling cassette indoor units. Three wireless remote controllers guarantee convenient comfort by allowing you to control the temperature in individual rooms. With multiple operating modes and multiple fan speeds, this is a system that fits the needs of nearly any home.
  • Precision Temperature Control Technology
  • The MXZ-5C42NAHZ outdoor condenser is equipped with inverter technology and an electronic linear expansion valve. These components improve temperature accuracy and 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 comfort and reduces the chance of mold growth and other property damage in the conditioned space.
  • Recommended line set sizes for indoor unit connectivity:
  • MLZ-KP09NA: 1/4" x 3/8" Line Set (Qty 1)
  • MLZ-KP12NA: 1/4" x 3/8" Line Set (Qty 1)
  • MLZ-KP18NA: 1/4" x 1/2" Line Set (Qty 1)
  • A branch box with a 3/8" x 5/8" line set connection is also required. Additional branch boxes and line sets may be required based on your configuration.
  • Product Includes
    • (1) Mitsubishi - 42k BTU - M-Series H2i Outdoor Condenser - For 2-5 Zones (MXZ-5C42NAHZ2)
    • (1) Mitsubishi - 18k BTU - M-Series One-Way Ceiling Cassette without Grille - For Multi or Single-Zone (MLZ-KP18NA)
    • (1) Mitsubishi - 12k BTU - M-Series One-Way Ceiling Cassette without Grille - For Multi or Single-Zone (MLZ-KP12NA)
    • (1) Mitsubishi - 9k BTU - M-Series One-Way Ceiling Cassette without Grille - For Multi or Single-Zone (MLZ-KP09NA)
    • (3) Mitsubishi MLP-444W Ceiling Cassette Grille For Mitsubishi MLZ-KP Mini Split Units (MLP-444W)
    Product Note
    Each indoor unit will include any port adapters necessary for multi-zone installation. This product requires the following accessories for installation:
    • Line Set - This double insulated tubing transfers refrigerant efficiently between your outdoor condenser and indoor units.
    • Branch Box - A Mitsubishi branch box is required to connect this condenser to Mitsubishi mini split indoor units.
    • Drain Tubing - Drain tubing facilitates the reliable and effective removal of condensate from your system. It connects your indoor units to drain locations of your choosing.
    • 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 may also require one or more Secondary Installation Kits if you have a Multi-Zone system. You will need a Secondary Installation Kit for each additional indoor unit.
