• Electro-static, washable, pleated filters as standard (included with fascia panel) Built in condensate pump with maximum 29" lift from the bottom of the unit, check valve, and float switch that disables indoor unit during overflow detection Fascia panel shall have LED indicator lights and a motorized louver High-voltage terminal block temperature sensor to disable unit in the event of power connection overheating WindFree™ function will close the supply air outlet louver while in cooling mode to gently disperse cool air into the space without blowing directly onto occupants. The WindFree™ feature is optional and can be enabled using central or local control options (MWRSH11UN, MWR-WE13UN, MWR-WG00*N, and AR-EH03U only) The WindFree™ 1-way cassette can be configured for 2-stage operation, cooling the space with the louver open (fixed or swing) until the room temperature nears set temperature. Once room temperature is near set temperature, WindFree™ operation will start automatically, closing the louver and using the face of the fascia panel to gently cool the space with still air The WindFree™ panel (PC1MWFMUN) has an integral humidity sensor that will open the louvers for standard cool mode when space conditions could potentially cause condensation formation on the panel surface

Samsung's WindFree™ 1-Way Cassette uses thousands of micro holes to distribute air throughout the space without blowing directly on the occupants. You can activate WindFree™ cooling by pressing the WindFree™ button on the controller. 5K and 7K Btu/h models fit in between conventional 16" on center framing providing more application and installation flexibility. The WindFree™ unit delivers an air current that is under 0.15 m/s while in WindFree™ mode. Air velocity that is below 0.15 m/s is considered "still air" as defined by ASHRAE 55-2013 (American Society of Heating, Refrigerating, and Air-Conditioning Engineers).
