Cassette indoor unit 4-flow Mitsubishi Electric SLZ-M35FA SLP-2FAL

The Mitsubishi Electric SLZ-M FA series cassette inverter air conditioners with 4 airflow ducts are highly efficient models with low noise levels and low energy consumption. The compact internal units, with a height of 24.5 cm, are designed for installation in ceiling tiles of 60 cm × 60 cm. These air conditioners can automatically switch between cooling or heating modes to maintain the desired room temperature.

The SLZ-M FA series cassette split systems by Mitsubishi Electric offer the option to connect a fresh air intake duct. The horizontal louver drive ensures that the airflow is evenly distributed throughout the room, even in spaces with low ceilings. The external unit control system adjusts the fan speed to stabilize the refrigerant condensation pressure, allowing the room to be cooled even at low outdoor temperatures, down to -15ºC (50/60VA).

Features of Mitsubishi Electric SLZ-M FA series cassette air conditioners:

⏵Fresh air intake.

⏵To reduce energy consumption, both the internal and external units are equipped with high-efficiency DC brushless electric motors for the fan drives, which reduces fan speed and noise.

⏵The use of amplitude pulse modulation has allowed the current in the inverter system’s power supply to approximate a sinusoidal waveform, eliminating higher harmonics. The minimal phase shift between voltage and current ensures an active load character and a power factor close to ideal (98%).

⏵Heat exchangers are made using tubes with internal fins to enhance heat transfer and increase energy efficiency.

⏵The compressor’s electric motor rotor is made from rare-earth metals, enhancing power and reducing energy consumption.

⏵The electric motor stator features a concentrated winding and a special “Poki Poki Core” structure that significantly increases efficiency.

⏵Extended life filter: the polypropylene fiber surface of the filter is specially “activated” for efficient filtration and extended service intervals.

⏵“Check Filter” reminder function to indicate when the filter needs cleaning after the selected interval.

⏵The built-in daily timer allows for setting the system’s on and off times. The configured cycle can be repeated daily if needed, with a 5-minute time step.

⏵Auto-restart to return the air conditioner to its previous operating mode after power restoration.

⏵Internal units can operate within multi-split inverter systems based on MXZ outdoor units.

⏵Fault codes recorded during system operation are stored in non-volatile memory and can be checked during diagnostics.

⏵Optional: “3D I-See” sensor, providing comfortable air distribution and energy savings. This sensor detects infrared radiation, measures temperature at different points in the room, and determines the location of people. Based on this data, it manages automatic airflow deflection/aiming modes, energy-saving modes, adjusts airflow direction to balance temperature, switches to standby mode, or completely shuts down the system (if no people are present in the room for over 1 hour).

⏵The built-in drainage pump, equipped with a DC motor, operates quietly and with low energy consumption, allowing for the lift of the drainage pipe.
