IMPORTANT SAFETY INFORMATIONWARNINGS:CAUTIONS: R -410A systems operate at approximately 60%higher pressures (1.6 times) than R-22 systems. Donot use R-22 service equipment or components onR-410A equipment. Use appropriate care when usingthis refrigerant. Failure to exercise care may result inequipment damage or personal injury. O nly match this outdoor unit with a matched indoorcoil or air handler approved for use with this outdoorunit per the unit manufacturer’s specification sheet.The use of unmatched coils or air handler will likelyresult in a charge imbalance between the coolingand heating modes which can cause unsatisfactoryoperation including a high-pressure switch lockoutcondition. O nly use indoor coils approved for use on R-410Asystems. An R-22 coil will have a TXV or fixedrestrictor device that is not designed to operateproperly in an R-410A system and will result inserious operational issues. The R-22 coil could alsocontain mineral oil which is incompatible with thePOE oil used in R-410A systems and could result inreliability issues with the compressor and TXVs. W hen coil is installed over a finished ceiling and/orliving area, it is required that a secondary sheet metalcondensate pan be constructed and installed underthe entire unit. Failure to do so can result in propertydamage. T he compressor has an internal overload protector.Under some conditions, it can take up to 2 hours forthis overload to reset. Make sure overload has hadtime to reset before condemning the compressor.Safety T hese instructions are intended as an aid toqualified, licensed service personnel for properinstallation, adjustment, and operation of thisunit. Read these instructions thoroughly beforeattempting installation or operation. Failure tofollow these instructions may result in improperinstallation, adjustment, service, or maintenancepossibly resulting in fire, electrical shock,property damage, personal injury, or death. The unit must be permanently grounded. Failureto do so can cause electrical shock resulting insevere personal injury or death. Turn off electric power at the fuse box or servicepanel before making any electrical connections. Complete the ground connection before makingline voltage connections. Failure to do so canresult in electrical shock, severe personal injury,or death. Disconnect all power to unit before startingmaintenance. Failure to do so can causeelectrical shock resulting in severe personalinjury or death. Never assume the unit is properly wired and/orgrounded. Always test the unit cabinet with anoncontact voltage detector available at mostelectrical supply houses or home centers beforeremoving access panels or coming into contactwith the unit cabinet. Do not use oxygen to purge lines or pressurizesystem for leak test. Oxygen reacts violently withoil, which can cause an explosion resulting insevere personal injury or death. T he top of the scroll compressor shell is hot.Touching the compressor top may result in seriouspersonal injury. T he manufacturer’s warranty does not coverany damage or defect to the unit caused by theattachment or use of any components, accessories,or devices (other than those authorized by themanufacturer) into, onto, or in conjunction withthe heat pump.

INSTALLATIONChoosing a LocationIMPORTANT: Consult local andnational building codes and ordinances for specialinstallation requirements. Following locationinformation will provide longer life and simplifiedservicing of the outdoor unit.NOTICE: These units must be installedoutdoors. No ductwork can be attached, orother modifications made, to the discharge grille.Modifications will affect performance or operation.Operational Issuesin a manner that will not prevent, impair, orcompromise the performance of other equipmentinstalled in proximity to the unit. Maintain allrequired minimum distances to gas and electricmeters, dryer vents, and exhaust and inletopenings. In the absence of national codes ormanufacturers’ recommendations, local coderecommendations and requirements will takeprecedence. Refrigerant piping and wiring should be properlysized and kept as short as possible to avoidcapacity losses and increased operating costs. Locate the unit where water runoff will not createa problem with the equipment. Position the unitaway from the drip edge of the roof wheneverpossible. Units are weatherized, but can beaffected by the following: Water pouring into the unit from the junctionof rooflines, without protective guttering.Large volumes of water entering the unit whilein operation can impact fan blade or motorlife, and coil damage may occur if moisturecannot drain from the unit under freezingconditions. Closely follow the clearance recommendationson page 8. 24" [61.0 cm] to the service panel access 60" [152.4 cm] above fan discharge (unit top)to prevent recirculation 6" [15.2 cm] to coil grille air inletswith 12" [30.5 cm] minimum recommendedThe metal parts of this unit may be subject torust or deterioration if exposed to a corrosiveenvironment. This oxidation could shorten theequipment’s useful life.Corrosive elements include, but are not limited to,salt spray, fog or mist in seacoast areas, sulphur orchlorine from lawn watering systems, and variouschemical contaminants from industries such aspaper mills and petroleum refineries.If the unit is to be installed in an area wherecontaminants are likely to be a problem, specialattention should be given to the equipmentlocation and exposure. Avoid having lawn sprinkler heads spray directlyon the unit cabinet. In coastal areas, locate the unit on the side ofthe building away from the waterfront. Shielding provided by a fence or shrubs maygive some protection, but cannot violateminimum airflow and service access clearances. Elevating the unit off its slab or base enough toallow air circulation will help avoid holding wateragainst the base pan.LocationIMPORTANT: Locate the unitCorrosive EnvironmentWARNING:Disconnect all powerto unit before starting maintenance. Failure to doso can cause electrical shock resulting in severepersonal injury or death.Regular maintenance will reduce the buildup ofcontaminants and help to protect the unit’s finish. Frequent washing of the cabinet, fan blade, andcoil with fresh water will remove most of the saltor other contaminants that build up on the unit. Regular cleaning and waxing of the cabinet witha good automobile polish will provide someprotection. A good liquid cleaner may be used several timesa year to remove matter that will not wash offwith water.7
INSTALLATIONChoosing a Location (cont.)For Units With SpaceLimitationsLocationIn the event that a space limitation exists, we willpermit the following clearances:Single-Unit Applications: Side clearances below 6"[15.2 cm] will reduce unit capacity and efficiency.Do not reduce the 60" [152.4 cm] discharge or the24" [61.0 cm] service clearances.Multiple-Unit Applications: When multiplecondenser grille sides are aligned, a 6" [15.2cm] per unit side clearance is recommended fora total of 12" [30.5 cm] between two units. Twocombined clearances below 12" [30.5 cm] willreduce capacity and efficiency. Do not reduce the60" [152.4 cm] discharge or 24" [61.0 cm] serviceclearances.ALLOW 60” [1524 mm]OF CLEARANCE12” Min.
