It is designed to be custom matched with one of our com-plete line of evaporator sections, each designed to serve a specificfunction. Matching air handlers are available for upflow, downflow,and horizontal left or right application to provide a complete system.Electric heaters are available if required. Add-on coils are availablefor use with upflow, downflow, or horizontal furnaces. Field installedaccessories are available as needed.WARRANTY5-year limited parts warranty.10-year limited compressor warranty.FEATURES• Superior Coil Protection – A stamped decorative metal coilguard completely protects coil from debris and other large dam-aging material while a polymer mesh further protects the coilagainst smaller particles.• Isolated Compressor Compartment – A molded compositebulkhead isolates the compressor from the rest of the unit reduc-ing sound and vibration.• Protected Compressors – Each compressor is protectedagainst high and low pressure as well as excessive temperature.This is accomplished by by the simultaneous operation of a highpressure relief valve and temperature sensors which protect thecompressor if undesirable conditions occur.• Environmentally Friendly Refrigerant – Next generationrefrigerant R-410A delivers environmentally friendly perfor-mance, with zero ozone depletion.• Durable Finish – Automotive quality finish provides the ultimateprotection from harmful U.V. rays as well as rust creep ensuringlong-lasting high quality appearance. A powder-paint topcoat isapplied over a baked-on primer, using a galvanized, zinc coatedsteel base material. The result is a finish that has been proven intesting to provide 33% greater durability than conventional pow-der-coat finishes.• Lower Installed Cost – Designed to provide enhanced install-ability by featuring a slide-down control compartment allowingeasy access to control components along with angled servicevalves to reduce overall installation time and cost.• Low Operating Sound Levels – A fan design boasting technol-ogy adapted from aeronautic and defense engineering providesfor whisper quiet operation by allowing airflow to flow smoothlyand efficiently across the fan tips.• Filter-Drier – A factory installed, solid core liquid line filter-drierfilters harmful debris and moisture from the system.• Easy Service Access – A full end, full service, access panelwith handle makes for easy entry to internal components.• Long Lasting Operation – Strong and durable composite basepan provides added strength while resisting rust and corrosionas well as reducing sound and vibration.• Complete System Control – These heat pumps utilize theunique microprocessor defrost control system to provide optimalcomfort as well as monitor the overall system for reliable opera-tion. The defrost control system continuously monitors the spaceenvironment to maintain optimum efficiency. It initiates defrostonly when necessary to further reduced heating costs andimprove reliability. Supplemental heat can only operate belowthe balance point and then only upon need. In the eventimproper operating conditions occur (high temperature and/orhigh pressure), the will automatically shut the system down toextend the life of the heat pump. Rapid cycling is prevented byuse of an internal anti-recycle timer. The defrost control featuresan internal memory to aid the technician in troubleshooting,reducing service time and cost.• Agency Listed - U.L. and C.U.L. listed - approved for outdoorapplication. The unit is certified in accordance with the UnitarySmall Equipment cerification program, which is based on ARIStandard 210/240.
