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.
- Advanced Filtration System
- The MSZ-FS Series uses Triple-action Filtration: Nano Platinum Filter, Deodorizing Filter and Electrostatic Anti-Allergy Enzyme Filter.
- 3D i-see Sensor
- The MSZ-FS Series 3D i-see Sensor monitors its zone for fluctuations in temperature. If it detects an underserved area, it will temporarily direct airflow to that zone. It also enters energy saving mode if no human heat signatures are detected.
- Dual Barrier Coating
- A special coating is applied to the heat exchanger, vanes and fan to prevent hydrophilic and hydrophobic dirt build-up.
- Multiple Fan Speeds
- With multiple fans speeds like Quiet, Low, Medium, High, Super-High, Mitsubishi delivers the options that keep you comfortable.
- Hot-Start
- Mitsubishi's hot-start technology prevents cold drafts by delaying fan operation until the heat exchanger has warmed up.
- Vane Control
- Thanks to its double vane features it separates airflow to deliver air across a large area and can simultaneously deliver to air separate sections of a room to generate a more comfortable natural airflow pattern.
- Precision Temperature Control Technology
- The outdoor condenser is equipped with a variable speed inverter-driven compressor.
- M-NET connection through outdoor unit.
- Enables centralized and individual control of M series models using M-NET Interface.

- (3) Mitsubishi FS-Series 9k BTU Wall Mounted Unit - For Multi or Single-Zone (MSZ-FS09NA)
- 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.

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.
