Durable & Reliable Construction * Stainless steel endplates reduce outdoor coil corrosion. * Galvanized zinc coated steel wall sleeve and steel base pan undergo an 11-step preparation process, are powder coated with a polyester finish and cured in an oven for exceptional durability. * Additional heating element bottom plate above an improved heat shield provides extra thermal protection. * Additional thermistor on the blower scroll outlet regulates internal temperature. * Factory run-tested units reduce problems in the field. * Internal diagnostic program can alert maintenance to component * failures or operating problems. Fourteen numeric service error codes stored in memory facilitate rapid unit diagnostics. * Easy access filters simplify maintenance and extend the life of the product. * Room freeze protection initiates heat if temperature falls to 40°F in an unoccupied room. * Random compressor restart protects electrical systems from overload when power is restored. * Tamper-resistant, anodized stamped aluminum grille withstands chalking and oxidation. * Break-proof control door design maintains the integrity of the unit. * Indoor coil frost sensor protects the compressor to lengthen the life of the unit. * Diamonblue Advanced Corrosion Protection® protects the outdoor coil from harsh environments. Warranty and Support * Industry leading warranty features 2-year full warranty on parts and labor and 5-year limited warranty. * Nationwide service network and U.S. based Friedrich expert technical team ensures you get fast, knowledgeable service. Energy Efficient & Energy Smart * Super-efficient refrigeration design with EERs up to 13.0 and COP up to 3.6. * Exceptional FriedrichLink® energy management thermostats available (wired & wireless) with integrated occupancy sensor, five distinct energy presets and comprehensive remote management capability.* * Advanced coil design adds more surface area leading to higher efficiencies. * Thicker steel inner-wall and foam construction decreases thermal transfer and energy loss. * Energy efficient heat pump models available in our complete line. * Electronic defrost control ensures more run time in efficient heat pump mode. * Electronic temperature limiting to adjust low/high temperature range limits for reduced energy usage. * Slinger ring technology in condensate removal system cools the coil and increases efficiency. * Desk control ready to allow hotel owners to control units from a central location. Sound Reduction Technology * Two permanently lubricated fan motors for added durability and reduced sound levels indoors. * Quiet, efficient rotary compressor mounted with vibration isolators to keep the compressor running smoothly and quietly. * High-density insulation and steel inner wall block outdoor noise. * Tangential blower wheel creates a wide path air flow that reaches the furthest corner of the guest room more quietly than conventional fans. FreshAire® IAQ Ready * A full complement of Indoor Air Quality Products has been certified through installation and testing to ensure exceptional air quality is achieved when FreshAir IAQ accessories are added * Dehumidification removes up to 3.1 pints/hour of moisture in cool mode to improve comfort and reduce the chance of mold and mildew growth. * Constant Fan mode provides continuous fan operation in cooling or heating modes to create a steady stream of white noise that masks sound level changes when the compressor cycles on/off. * Fresh air damper brings in fresh outside air when desired. * Intuitive unit controls are user friendly with easy-to-read LED display that can show either set-point or actual room temperature as selected by owner. * Air filters are easy to access and washable. * Instant Heat on heat pump models quickly heats a room to the desired temperature for increased comfort. * Even-heat monitoring checks room temperature and automatically adds heat boost if necessary. * Automatic periodic sampling of room temperature to ensure desired conditions are maintained. * Reversible indoor air louvers to easily change airflow direction. Ease of Maintenance & Installation * Modular product design ensures easy access to key components for cleaning and repairs; including washable, lift-out air filters. * Remote thermostat pop-out wiring module allows easier wiring and unit change out without rewiring thermostat. * Standard power cord installed on each unit (7-12k-3.5KW), (15K-5.0 KW) * Compact front is designed to preserve indoor floor space with a depth of 7¾ inches. * Surehold Front Cover System® securely attaches the front each time. * Inner wall service plate provides service access to tangential blower bearing without having to open up the entire inner wall. * Unit may be installed flush with the floor.
