Engineering FeaturesUBHK- SeriesQuiet, efficient ECM motor technology providing nominal airflowto 1.0 inch [25 kPa] of external static pressure. Interface board with dip switches conveniently located in theblower compartment allows for precise, field selectable airflowto meet the requirements of particular applications. Selectable continuous fan “on” options. The most compact unit design available. Attractive pre-painted cabinet exterior. Rugged double wall steel cabinet construction, designed foradded strength and versatility. .5" foil faced insulation mechanically retained in blowercompartment. Four leg rubber insulated wire motor mount. Circuit breakers standard on 1-phase models above 11 kW andoptional on models with 11 kW or less. Models supplied with circuit breakers meet UL and cUL requirements as a service disconnect switch. Provisions for field electrical connections from either side of airhandler cabinet. Tab lock blower housing with integrated electric heaters, controls, motor and blower. Slide out design for service and maintenance convenience. Exclusive dependable Incoloy sheath type electric heatingelements located in the blower housing provide mixed warm air. Field convertible for vertical upflow, vertical downflow, horizontal left hand or right hand air supply. Common combustible floor base accessory fits all model sizeswhen required for downflow installations on combustible floors. Durable framed cleanable air filter provided as standard in unitfilter rack. MultiFlex indoor coil design provides low air side pressuredrop, high performance and extremely compact size. All coilscome with PVC condensate elbow standard. All indoor coils have copper tubing and aluminum fins. Molded polymer corrosion resistant condensate drain pan isprovided on all indoor coils. Both supply and return duct flanges provided as standard on airhandler cabinet. Connection points for both high voltage and low voltage controlwiring inside air handler cabinet. Concentric knockouts are provided for power connection tocabinet. Installer may pull desired hole size up to 2 inches[51 mm] for 11/2 inch [38 mm] conduit. Patented watt restrictor on heat pump models to control electricheat during heating operation. Internal checked TX valves are used on the RCHJ Heat Pumpindoor coil for more quiet refrigerant metering. Front refrigerant and drain connections. Watt-restrictorSupplemental heat, provided by electric heating elements may be necessary in some areaswhen heating requirements for indoor comfort exceed the capacity of the heat pump system.When supplemental heat is required, units with the Watt Restrictor will restrict the amount ofsupplemental electric heat that can be energized dependent on the heat ouput of the heatpump (temperature of the air leaving the indoor heat pump coil).The Watt-restrictor utilizes sensing devices in the unit to sense the air temperature leavingthe indoor coil and disengage unnecessary heating elements when that temperature is atleast 85 F [29 C]. (In this mode your system is controlled by the first stage of the wall thermostat.) This occurs only when the second stage of the wall thermostat calls for heat.Since the heat ouput of the heat pump is dependent upon the outdoor air temperature, thiscontrol performs the same function as a field installed outdoor thermostat.An additional benefit of the Watt Restrictor is that it can sense a degradation in heat pumpperformance due to causes other than outdoor temperature and react accordingly to bringon more supplemental electric heat.[] Designates Metric ConversionsECMMOTORGENERAL TERMS OFLIMITED WARRANTYRuud will furnish a replacement for any part of this productwhich fails in normal use and service within the applicableperiods stated, in accordance with the terms of the limitedwarranty.MultiFlex Coil leaks caused byfactory defects .Five (5) YearsElectric Heating Element .Five (5) YearsAny Other Part .Five (5) YearsBLOWERSECTION2Ruud Air Conditioning DivisionFor Complete Details of the Limited Warranty, IncludingApplicable Terms and Conditions, See Your Local Installer orContact the Manufacturer for a Copy.
