It is designed to becustom-matched with one of UPG’s complete line of evapora-tor sections, with each serving a specific function. MatchingAir Handlers are available for upflow, downflow, or horizontalapplications to provide a complete system. Electric Heatersare available, if required. Add-on coils are available for usewith upflow, downflow, or horizontal furnaces and air han-dlers.WARRANTYSingle Phase Units:5-year limited parts warranty.10-year limited compressor warranty.FEATURES• QUALITY CONDENSER COILS - The coil is constructedof copper tubing and enhanced aluminum fins forincreased efficiency and corrosion protection.• PROTECTED COMPRESSOR - The compressor is inter-nally protected against high pressure, temperature, andexternally by a factory installed high pressure switch. Thisis accomplished by the simultaneous operation of highpressure relief valve and a temperature sensor which pro-tects the compressor if undesirable operating conditionsoccur. A liquid line filter-drier further protects the compres-sor.• DURABLE FINISH - The cabinet is made of pre-paintedsteel. The pre-treated galvanized steel provides a betterpaint to steel bond, which resists corrosion and rust creep.Special primer formulas and matted-textured finish insureless fading when exposed to sunlight.• LOWER INSTALLED COST - Installation time and costsare reduced by easy power and control wiring connec-tions. Available in sweat connect models only. The unitcontains enough refrigerant for matching indoor coils and15 feet of interconnecting piping. The small base dimen-sion means less space is required on the ground or roof.• TOP DISCHARGE - The warm air from the top mountedfan is blown up away from the structure and any landscap-ing. This allows compact location on multi-unit applica-tions.• LOW OPERATING SOUND LEVEL - The upward air flowcarries the normal operating noise away from the livingarea. The rigid top panel effectively isolates any motorsound. Isolator mounted compressor and the rippled finsof the condenser coil muffle the normal fan motor andcompressor operating sounds.• LOW MAINTENANCE - Long life permanently lubricatedmotor-bearings need no annual servicing.• EASY SERVICE ACCESS - Fully exposed refrigerant con-nections, and a single panel covering the electrical con-trols make for easy servicing of the unit.• SECURED SERVICE VALVES - Secured re-usable ser-vice valves are provided on both the liquid and vaporsweat connections for ease of evacuating and charging.• U.L. and C.U.L. listed - approved for outdoor application.Certified in accordance with the Unitary Small Equipment cer-tification program, which is based on ARI Standard 210/240.
