Preface and Warnings and CautionsHazard Identification Warnings and Cautions appear atappropriate sections throughout thismanual. Read these carefully. WARNINGIndicates a potentially hazardoussituation which, if not avoided, couldresult in death or serious injury. CAUTIONIndicates a potentially hazardoussituation which, if not avoided, mayresult in minor or moderate injury. Itmay also be used to alert againstunsafe practices.CAUTIONIndicates a situation that may resultin equipment or property-damageonly accidents. Take precautions to preventcondensate from forming inside theunit’s electrical compartments andmotors if:1.the unit is stored before it isinstalled; or,2.the unit is set on the roof curb,and temporary heat is providedin the building. Isolate all sidepanel service entrances and basepan openings (e.g., conduitholes, S/A and R/A openings, andflue openings) from the ambientair until the unit is ready for startup.As soon as the unit arrives at the jobsiteVerify that the nameplate datamatches the data on the salesorder and bill of lading (includingelectrical data). Verify that the power supplycomplies with the unitnameplate specifications. Visually inspect the exterior ofthe unit, including the roof, forsigns of shipping damage.If the job site inspection of the unitreveals damage or materialshortages, file a claim with the carrierimmediately. Specify the type andextent of the damage on the “bill oflading” before signing. Visually inspect the internalcomponents for shippingdamage as soon as possible afterdelivery and before it is stored.Do not walk on the sheet metalbase pans. If concealed damage isdiscovered, notify the carrier’sterminal of damage immediatelyby phone and by mail. Concealeddamage must be reported within15 days.Notify the appropriate salesrepresentative before installingor repairing a damaged unit.StorageUnit Inspection Request an immediate jointinspection of the damage by thecarrier and the consignee. Do notremove damaged material fromthe receiving location. Takephotos of the damage, ifpossible. The owner mustprovide reasonable evidence thatthe damage did not occur afterdelivery.Note:Do not use the unit’s heaterfor temporary heat withoutfirst completing the start-upprocedure detailed under“Starting the Unit”.The manufacturer will not assumeany responsibility for equipmentdamage resulting from condensateaccumulation on the unit’s electricaland/or mechanical components.Model Number DescriptionOverview of ManualNote:One copy of this documentships inside the control panelof each unit and is customerproperty. It must be retainedby the unit’s maintenancepersonnel.This booklet describes properinstallation, operation, andmaintenance procedures for aircooled systems. By carefullyreviewing the information within thismanual and following theinstructions, the risk of improperoperation and/or component damagewill be minimized.It is important that periodicmaintenance be performed to helpassure trouble free operation. Amaintenance schedule is provided atthe end of this manual. Shouldequipment failure occur, contact aqualified service organization withqualified, experienced HVACtechnicians to properly diagnose andrepair this equipment. WARNINGContains Refrigerant!System contains oil and refrigerantunder high pressure. Recoverrefrigerant to relieve pressure beforeopening the system. See unitnameplate for refrigerant type. Donot use non-approved refrigerants,refrigerant substitutes, or refrigerantadditives.Failure to follow proper proceduresor the use of non-approvedrefrigerants, refrigerant substitutes,or refrigerant additives could resultin death or serious injury orequipment damage.All products are identified by amultiple-character model numberthat precisely identifies a particulartype of unit. Its use will enable theowner/operator, installingcontractors, and service engineers todefine the operation, specificcomponents, and other options forany specific unit.When ordering replacement parts orrequesting service, be sure to refer tothe specific model number and serialnumber printed on the unitnameplate. 2007 American Standard Inc.

Preface and Warnings and Cautions WARNINGHazardous Voltage w/Capacitors!Disconnect all electric power,including remote disconnects anddischarge all motor start/runcapacitors before servicing. Followproper lockout/tagout procedures toensure the power cannot beinadvertently energized. Verify withan appropriate voltmeter that allcapacitors have discharged. Failureto disconnect power and dischargecapacitors before servicing couldresult in death or serious injury.CAUTIONRoof Damage!System contains oil and refrigerantunder high pressure. Roofs should beprotected from exposure to oils andrefrigerant in the system. If rooftop isnot protected damage to the roofmay occur. CAUTIONR410a Refrigerant!R-410A refrigerant systems operateat higher pressures than standard R22 systems. Do not use R-22 serviceequipment or components on R410A refrigerant equipment. Ifservice equipment is not rated for R410A refrigerant, equipment damageor personal injury may result. CAUTIONEquipment Damage FromUltraviolet (UV) Lights!The manufacturer does notrecommend field installation ofultraviolet lights in its equipment forthe intended purpose of improvingindoor air quality. High intensity Cband ultraviolet light is known toseverely damage polymer (plastic)materials and poses a personalsafety risk to anyone exposed to thelight without proper personalprotective equipment. Polymermaterials commonly found in HVACequipment that may be susceptibleinclude insulation on electricalwiring, fan belts, thermal insulation,various fasteners and bushings.Degradation of these materials canresult in serious damage to theequipment.The manufacturer accepts noresponsibility for the performance oroperation of our equipment in whichultraviolet devices were installedoutside of the manufacturer’s factoryor its approved suppliers.RT-SVX22E-EN3

General InformationUnit NameplateA Mylar unit nameplate is located onthe unit’s corner support next to thefilter access panel. It includes theunit model number, serial number,electrical characteristics, refrigerantcharge, as well as other pertinentunit data.Compressor NameplateThe nameplate for the compressorsare located on the side of thecompressor.Unit DescriptionBefore shipment, each unit is leaktested, dehydrated, charged withrefrigerant and compressor oil, andrun tested for proper controloperation.The condenser coils are aluminumfin, mechanically bonded to coppertubing.Direct-drive, vertical dischargecondenser fans are provided withbuilt-in thermal overload protection.There are two control systemsoffered for these units. The electromechanical control option uses athermostat to perform unit functions.The ReliaTel Control Module is amicroelectronic control system thatis referred to as “RefrigerationModule” (RTRM). The acronymRTRM is used extensivelythroughout this document whenreferring to the control systemnetwork.These modules throughProportional/Integral controlalgorithms perform specific unitfunctions that governs unit operationin response to; zone temperature,supply air temperature, and/orhumidity conditions depending onthe application. The stages ofcapacity control for these units areachieved by starting and stoppingthe compressors.The RTRM is mounted in the controlpanel and is factory wired to therespective internal components. TheRTRM receives and interpretsinformation from other unitmodules, sensors, remote panels,8and customer binary contacts tosatisfy the applicable request forcooling.RLCI - ReliaTel LonTalkCommunication Interface(Optional)Economizer Control Actuator(Optional)This module is u
