Overview for Mitsubishi MXZ-5C42NA4 2-MLZ-KY06 MLZ-KP12 MLZ-KP18

For over 50 years, Mitsubishi has remained at the forefront of the mini split industry thanks to their dedication to providing efficient, user-friendly comfort solutions. This is a four-zone mini split system designed to give you individual control over the temperature in multiple rooms. An efficient MXZ-5C42NA4 outdoor condenser, built with advanced technology, is combined with quiet ceiling cassette MLZ indoor units and four wireless remote controllers for the perfect marriage of convenience and comfort. 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.
  • 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 thanks to the vane control option. This function provides access to an auto mode and a swing mode.
  • Condensate Removal System
  • The MLZ 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 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:
  • MLZ-KY06NA: 1/4" x 3/8" Line Set (Qty 2)
  • MLZ-KP12NA2: 1/4" x 3/8" Line Set
  • MLZ-KP18NA2: 1/4" x 1/2" Line Set
  • Product Note
    This product requires the following accessories for installation: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.Base Pan Heater - The base pan heater prevents ice from building up on the outdoor unit. Excessive ice build will lead to performance issues and could damage your unit.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.
