Manual 2100-347HPage 6 of 23SHIPPING DAMAGEUpon receipt of equipment, the carton should bechecked for external signs of shipping damage. Ifdamage is found, the receiving party must contact thelast carrier immediately, preferably in writing,requesting inspection by the carrier’s agent.GENERALThe equipment covered in this manual is to be installedby trained, experienced service and installationtechnicians.The refrigerant system is completely assembled andcharged. All internal wiring is complete.The unit is designed for use with or without duct work.Flanges are provided for attaching the supply and returnducts.These instructions explain the recommended method toinstall the air cooled self-contained unit and theelectrical wiring connections to the unit.These instructions and any instructions packaged withany separate equipment, required to make up the entireair conditioning system should be carefully read beforebeginning the installation. Note particularly “StartingProcedure” and any tags and/or labels attached to theequipment.1 Maximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors.2 Based on 75°C copper wire. All wiring must conform to NEC and all local codes.3 These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National ElectricCode (latest revision), article 310 for power conductor sizing.CAUTION: When more than one field power conductor circuit is run through one conduit, the conductors must be derated.Pay special attention to note 8 of table 310 regarding Ampacity Adjustment Factors when more than 3 conductorsare in a raceway.While these instructions are intended as a generalrecommended guide, they do not supersede any nationaland/or local codes in any way. Authorities havingjurisdiction should be consulted before the installation ismade. See Page 3 for information on codes andstandards.Size of unit for a proposed installation should be basedon heat loss calculation made according to methods ofAir Conditioning Contractors of America (ACCA). Theair duct should be installed in accordance with theStandards of the National Fire Protection Associationfor the Installation of Air Conditioning and VentilatingSystems of Other Than Residence Type, NFPA No.90A, and Residence Type Warm Air Heating and AirConditioning Systems, NFPA No. 90B. Where localregulations are at a variance with instructions, installershould adhere to local codes.DUCT WORKAny heat pump is more critical of proper operatingcharge and an adequate duct system than a straight airconditioning unit. All duct work, supply and return,must be properly sized for the design airflowrequirement of the equipment. Air ConditioningContractors of America (ACCA) is an excellent guide toproper sizing. All duct work or portions thereof not inthe conditioned space should be properly insulated inorder to both conserve energy and prevent condensationor moisture damage.TABLE 2ELECTRICAL SPECIFICATIONSTIUCRICELGNIS TIUCRICLAUDledoMdetaR&stloVesahP.oNdleiFrewoPstiuriC3muminiMtiucriCyticapmA1mumixaMlanretxEroesuFtiucriCrekaerB2dleiFrewoPeriWeziS2dnuorGeriWeziS3muminiMtiucriCyticapmA1 mumixaMlanretxEroesuFtiucriCrekaerB2dleiFrewoPeziSeriW2dnuorGeziSeriW.tkCA.tkCB.tkCA.tkCB.tkCA.tkCB.tkCA.tkCBZ0A,00A-116HW50A80A01A1-802/0321-802/0321-802/0321-802/03212ro12ro12ro12547888906001011021643301866---252525---622425---060606---030506---666---0186---010101---010101Z0B,00B-116HW90B1-802/0321-802/0321163060507860101------------------------------------------------Z0C,00C-116HW90C3-0643-06411812352530180101-----------------------------------------------
