5 All wiring must conform to the National Electrical Code and all local "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 circuitis run through one conduit, the conductors must be derated. Pay special attention to note 8 of table 310 regardingAmpacity Adjustment Factors when more than three conductors are in a 1 ELECTRICAL SPECIFICATIONS ledoMdetaR& ,00A-103AW50A01A51A1-802/0321112ro142137 5385353060988640101018---------55------- --62---------06---------03---------4---- -----01---------8---------01Z0B,00B-103A W90B51B3-802/032111712305025305218821010 1--------------------------------------- ---------------------------------Z0C,00C -103AW90C51C3-06411101716251020341210141 2101------------------------------------ ------------------------------------Z0A, 00A-163AW50A01A51A1-802/0321112ro1721375 385353060988640101018---------55-------- -62---------06---------03---------4----- ----01---------8---------01Z0B,00B-163AW 90B51B3-802/0321110223055253050188010101 ---------------------------------------- --------------------------------Z0C.

Ifdamage is found, the receiving party must contact thelast carrier immediately, preferably in writing,requesting inspection by the carrier s equipment covered in this manual is to be installedby trained, experienced service and refrigerant system is completely assembled andcharged. All internal wiring is unit is designed for use with or without duct are provided for attaching the supply and instructions explain the recommended method toinstall the air cooled self-contained unit and theelectrical wiring connections to the instructions and any instructions PACKAGED withany separate equipment required to make up the entireair conditioning system should be carefully read beforebeginning the INSTALLATION .

7 Note particularly StartingProcedure and any tags and/or labels attached to 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 1 for information on codes 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 , and Residence Type Warm Air Heating and AirConditioning Systems, NFPA No. 90B. Where localregulations are at a variance with instructions, installershould adhere to local WORKAll duct work, supply and return, must be properly sizedfor the design air flow requirement of the Conditioning Contractors of America (ACCA) is anexcellent guide to proper sizing.

8 All duct work orportions thereof not in the conditioned space should beproperly insulated in order to both conserve energy andprevent condensation or moisture grille that meets the 5/8 inch louver criteria may beused. It is recommended that Bard Return Air Grille KitRG-2 through RG-5 or RFG-2 through RFG-5 beinstalled when no return duct is used. Contactdistributor or factory for ordering information. If usinga return air filter grille, filters must be of sufficient sizeto allow a maximum velocity of 400 1 inch throw away filter is suppled with each filter slides into position making it easy to filter can be serviced from the outside by removingthe service door. A 1 inch washable filter and a 2 inchpleated filter are also available as optional internal filter brackets are adjustable toaccommodate the 2 inch filter by loosening 2 screws ineach bracket assembly and sliding the brackets apart tothe required width and retightening the 4 to Table 10 for maximum static pressure availablefor duct the duct work according to methods given by theAir Conditioning Contractors of America (ACCA).

9 When duct runs through unheated spaces, it should beinsulated with a minimum of 1 inch of insulation. Useinsulation with a vapor barrier on the outside of theinsulation. Flexible joints should be used to connect theduct work to the equipment in order to keep the noisetransmission to a 1/4 inch clearance to combustible material for thefirst 3 feet of duct attached to the outlet air frame isrequired. See Wall Mounting Instructions and Figures 3and 4 for further through the walls must be insulated and all jointstaped or sealed to prevent air or moisture entering thewall cavity. CAUTIONSome installations may not require any returnair duct. A metallic return air grille is requiredwith installations not requiring a return airduct. The spacing between louvers on thegrille shall not be larger than 5/8 2100-192 Page 6 The blank-off plate is available upon request from thefactory and is installed in place of the fresh air dampershipped with each DRAINA plastic drain hose extends from the drain pan at thetop of the unit down to the unit base.
