Features
- Smart Set
- Mitsubishi's Smart Set function allows you to save a cooling profile and a heating profile, each consisting of a temperature, a fan speed, and an airflow direction. These profiles can be activated easily with a press of the Smart Set button on the remote.
- Econo Cool Mode
- By slowly adjusting the cooling set point and swinging the horizontal vanes, the MFZ-KJ can improve the efficiency of cooling operations without compromising the comfort provided.
- Powerful Mode
- The powerful setting on the MFZ-KJ makes it easy to get your zone to the perfect temperature quickly. When it is activated, the unit temporarily increases refrigerant flow and fan speed to provide quick comfort through rapid heating or cooling.
- Multiple Vane Control Options
- Auto mode selects the best vane position based on operating mode, and the swing modes cycle through all positions for maximum coverage.
- Multiple Airflow Options
- When 2 FLOW is selected the unit will blow air from the top and front of the unit. When 1 FLOW is selected, air only blows from the top of the unit.
- Dehumidification
- When the indoor unit is run in dry mode, it will remove unwanted moisture. This improves your comfort and reduces the chance of mold growth and other property damage in the room.
- Blue Fin Condenser
- Condensers are constantly exposed to wind, dust and salty air that take their toll on your unit. Mitsubishi coats their condensers with an anti-rust coating to extend its lifespan.
- Hot-Start
- Mitsubishi's hot-start technology prevents cold drafts by delaying fan operation until the heat exchanger has warmed up.
- Recommended line set sizes for indoor unit connectivity:
- MFZ-KJ09NA-U1: 1/4" x 3/8" Line Set
- MFZ-KJ12NA-U1: 1/4" x 3/8" Line Set (Qty 2)
- (1) Mitsubishi - 36k BTU - M-Series Outdoor Condenser - For 2-4 Zones (MXZ-4C36NA3)
- (2) Mitsubishi M-Series 12k BTU Floor Mounted Unit - For Multi or Single-Zone (MFZ-KJ12NA-U1)
- (1) Mitsubishi M-Series 9k BTU Floor Mounted Unit - For Multi or Single-Zone (MFZ-KJ09NA-U1)
- Line Set - This double insulated tubing transfers refrigerant efficiently between your outdoor condenser and 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.
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. Mitsubishi's floor mounted indoor units are a great alternative for rooms where you don't have the ceiling height or wall space to allow for a wall mounted unit. With three included wireless remote controllers, this system is the perfect combination of convenience and comfort for any heating or cooling application.

SEER2
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.

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. EER2 (Energy Efficiency Ratio) is a measurement of cooling efficiency under fixed conditions. It is useful for comparing units that will operate consistently under one set of conditions (e.g. server room). The higher the EER2, the more efficient the system.
