CONDENSATE DRAINPlumbing must conform to local codes. Use a sealingcompound on male pipe threads. Install a condensate drain linefrom the 19mm (3⁄4“) PVC female connection on the unit to spillinto an open drain.NOTE: The condensate drain line MUST be trapped to pro-vide proper drainage. See Figure 2.SERVICE ACCESSAccess to all serviceable components is provided by thefollowing removable panels:• Compressor compartment• Heater compartment• Blower compartment• Main control box• Filter compartment• Motor Access (on units w/belt-drive option)Refer to Figure 5 for location of these access panels.CAUTION: Make sure that all screws are replaced on theunit to maintain an air-tight seal.THERMOSTATThe room thermostat should be located on an inside wallapproximately 1422mm (56 in.) above the floor where it will notbe subject to drafts, sun exposure, or heat from electricalfixtures or appliances. Follow manufacturer’s instructionsenclosed with thermostat for general installation procedure.Color coded insulated wires (#18 AWG) should be used toconnect thermostat to unit. See Figure 4 for wiring details.NOTE: If the unit has an economizer, remove jumper J1from terminals 8 and 10 on the relay board to pre-vent simultaneous operation of the compressor andthe economizer. If you want to control the econo-mizer on a second stage of cooling, use a thermo-stat with two stages of cooling.POWER AND CONTROL WIRINGField wiring to the unit must conform to the applicable national andlocal or municipal codes.Voltage tolerances which must be maintained at thecompressor terminals during starting and running conditionsare indicated on the unit Rating Plate and Table 1.The internal wiring harness furnished with this unit is an integralpart of the unit. Field alteration to comply with electrical codesshould not be required.A fused disconnect switch should be field provided for the unit.The switch must be separate from all other circuits. Refer to Figure5 for installation location. If any of the wire supplied with theunit must be replaced, replacement wire must be of the typeshown on the wiring diagram.Electrical lines must be sized properly to carry the load. USECOPPER CONDUCTORS ONLY. Each unit must be wired witha separate branch circuit fed directly from the meter panel andproperly protected.CAUTION: When connecting electrical power and controlwiring to the unit, waterproof type connectorsMUST BE USED so that water or moisture can-not be drawn into the unit during normal opera-tion. The above waterproofing conditions willalso apply when installing a field-supplied discon-nect switch.Refer to Figure 4 for typical field wiring and to the appropriateunit wiring diagram for control circuit and power wiringinformation.BLOWER SPEED SELECTIONThree blower motor speeds are available on the direct-driveunits. The speed selection for the direct-drive units isdetermined by the CFM and ESP requirements of theapplications. All units with belt-drive option have an adjustablemotor pulley to achieve the above conditions.COMPRESSORSThe compressor in the 036, 048 and 060 units is mounted onsprings which have been tightened down for shipment only.After the unit is installed, back out the compressor bolts untilthe sleeve clears the top grommet.The 076 units are shipped with compressor mountingsfactory-adjusted and ready for operation.CAUTION: Do not loosen compressor mounting bolts.76mm (3")51mm (2")FIG. 2 - RECOMMENDED DRAIN PIPINGWEIGHTS (kg/lbs)Basic Unit036 249 / 550048 268 / 590060 286 / 630076 313 / 690ACCESSORIES / OPTIONSElectric Heat(Nominal KW)5 - 7 KW 8 / 1810 - 15 KW 10 / 2320 - 30 KW 13 / 28Economizer 23 / 50Motorized OutdoorAir Damper 22 / 48Relief/FixedAir Damper 5 / 10Roof Mounting Curb 42 / 92MODELS DCE036 048 060 076EvaporatorBlowerCentrifugal Blower (Dia. x Wd.mm (in.))Fan Motor HP (direct-drive)Fan Motor HP (Belt-Drive)305 x 254(12 x 10)1⁄2N/A305 x 254(12 x 10)3⁄4N/A305 x 254(12 x 10)N/A1.5305 x 279(12 x 11)N/A1.5EvaporatorCoilRows DeepFins Per 25mm (1 in.)Face Area (m2/ft2)3130.33 / 3.63130.40 / 4.33130.48 / 5.13130.48 / 5.1CondensorFanPropeller Dia.
