To avoid property damage, personal injury or death due to electrical shock, this unit MUST have an uninterrupted, unbroken electrical ground. The electrical ground circuit may consist of an appropriately sized electrical wire connecting the ground lug in the unit control box to the building electrical service panel. Other methods of grounding are permitted if performed in accordance with the National Electric Code (NEC)/American National Standards Institute (ANSI)/National Fire Protection Association (NFPA) 70 and local/state codes. In Canada, electrical grounding is to be in accordance with the Canadian Electric Code (CSA) C22.1. 56 48 42 37 34 Table 4 208/1/60 Supply Voltage - Temperature Rise Table °F NOTE: For installations not indicated above the following formula is to be used: TR = (kW x 3412) x (Voltage Correction) x 1.08 / CFM Where: TR = Temperature Rise kW = Heater Kit Actual kW 3412 = Btu per kW Voltage Correction =.96 (230 Supply Volts) =.92 (220 Supply Volts) =.87 (208 Supply Volts) 1.08 = Constant CFM = Measured Airflow Building Electrical Service Inspection This unit is designed for single-phase electrical supply. DO NOT OPERATE ON A THREE-PHASE POWER SUPPLY. Measure the power supply to the unit. The supply voltage must be in agreement with the unit nameplate power requirements and within the range shown in Table 5. Nominal Input 208/240 NOTE: The Temperature Rise Tables can also be used to determine the air handler airflow delivery. When using these tables for this purpose set the room thermostat to maximum heat and allow the system to reach steady state conditions. Insert two thermometers, one in the return air and one in the supply air. The temperature rise is the supply air temperature minus the room air temperature. Use HKR specification sheets to determine the HKR available for a given air handler. Minimum Voltage 187 Maximum Voltage 253 Table 5 Wire Sizing Wire size is important to the operation of your equipment. Use the following check list when selecting the appropriate wire size for your unit. HKR Installation • Wire size must carry the Minimum Circuit Ampacity (MCA). • Refer to the NEC (USA) or CSA (Canada) for wire sizing. The unit MCA for the air handler and the optional electric heat kit can be found on the unit Series and Rating Plate. • Wire size allows for no more than a 2% voltage drop from the building breaker/fuse panel to the unit. Follow instructions listed in Installation and Operating Instructions shipped with the heat kit. Electrical Supply Wire and MOP FIRE HAZARD! To avoid the risk of property damage, personal injury or fire, use only copper conductors. Refer to the latest edition of the National Electric Code or in Canada the Canadian Electric Code when determining the correct wire size. The following table shows the current carrying capabilities for copper conductors rated at 75oC with a 2% voltage drop. Use Table 6 to determine the voltage drop per foot of various conductors. HIGH VOLTAGE! Disconnect ALL power before servicing. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death.

Also, check with local or state codes for any special regional requirements. Protection can be in the form of fusing or HACR style circuit breakers. The Series and Rating Plate can be used as a guide for selecting the MAXIMUM overcurrent device. Refrigerant Lines This product is factory-shipped under pressure. Follow these instructions to prevent injury. A quenching cloth is strongly recommended to prevent scorching or marring of the equipment finish when welding close to the painted surfaces. Use brazing alloy of 5% minimum silver content. NOTE: Fuses or circuit breakers are to be sized larger than the equipment MCA but not to exceed the MOP. Electrical Connections – Supply Voltage USE COPPER CONDUCTORS ONLY. A knockout is provided on the air handler top panel or side to allow for the entry of the supply voltage conductors. If the knockouts on the cabinet sides are used for electrical conduit, an adapter ring must be used in order to meet UL1995 safety requirements. An NEC or CEC approved strain relief is to be used at this entry point. The wire is to be sized in accordance with the “Electrical Wire and MOP” section of this manual. Some areas require the supply wire to be enclosed in conduit. Consult your local codes. Tubing Preparation All cut ends are to be round, burr free, and clean. Failure to follow this practice increases the chances for refrigerant leaks. The suction line is spun closed and requires pipe cutters to remove the closed end. Post Brazing Quench all welded joints with water or a wet rag. Piping Size For the correct tubing size, follow the specification for the condenser/heat pump. Air Handler Only (Non-Heat Kit Models) The building supply connects to the stripped black and red wires contained in the air handler electrical compartment cavity. A ground screw is also contained in this area. Attach the supply wires to the air handler conductors as shown in the unit wiring diagram using appropriately sized solderless connectors or other NEC or CEC approved means. CAUTION Applying too much heat to any tube can melt the tube. Torch heat required to braze tubes of various sizes must be proportional to the size of the tube. Service personnel must use the appropriate heat level for the size of the tube being brazed. Air Handler With Non-Circuit Breaker Heat Kits A terminal block is provided with the HKR kit to attach the power supply and air handler connections. Follow the HKR Installation Manual and wiring diagram for complete wiring details. Special Instructions This coil comes equipped with a check style flowrator for refrigerant management. For most installations with matching applications, no change to the flowrator piston is required. However, in mix-matched applications, a flowrator piston change may be required. See the Goodman® piston kit chart or consult your local distributor for details regarding mixmatched piston sizing. If the mix-match application requires a different piston size, change the piston in the flowrator on the indoor coil before installing the coil and follow the procedure shown below. Air Handler With Heat Kits Containing a Circuit Breaker HKR models with a “C” suffix contain a circuit breaker(s). The air handler has a plastic cover on the access panel that will require either one or both sections to be removed to allow the heat kit circuit breaker(s) to be installed. See the HKR Installation Instructions for further details. The air handler wires and supply wires are installed directly onto the HKR circuit breaker(s) as shown in the HKR Installation Manual and wiring diagram. IMPORTANT NOTE: Torch heat required to braze tubes of various sizes is proportional to the size of the tube. Tubes of smaller size require less heat to bring the tube to brazing temperature before adding brazing alloy. Applying too much heat to any tube can melt the tube. Service personnel must use the appropriate heat level for the size of the tube being brazed. NOTE: The use of a heat shield when brazing is recommended to avoid burning the serial plate or the finish on the unit. Heat trap or wet rags should be used to protect heat sensitive components such as service valves and TXV valves. Low Voltage Connections Several combinations of low voltage schemes are available, depending on the presence of a heat kit and whether the heat kit is single-stage or multi-staging. The low voltage connections are determined by whether the outdoor unit is a condenser or heat pump. The 24V-control voltage connects the air handler to the room thermostat and condenser. Low voltage wiring is to be copper conductors. A minimum of 18AWG must be used for installations up to 50’ and 16AWG for installations over 50’. Low voltage wiring can be connected through the top of the cabinet or either side. See the “Thermostat Wiring” section of this manual for typical low voltage wiring connections. 1.

NOTE: ATUF models should not be converted to Downflow applications. “D” nomenclature models are factory equipped for “Dedicated Downflow” operation and no field conversion is required. Conversion to downflow MUST be performed in an area that allows access to all sides prior to placing the air handler in its final location. To prevent the evaporator coil pan from “sweating” the DPI accessory insulation kit is to be used when performing this conversion. NOTE: The DPI kit is not supplied with this product and is to be purchased separately. See Table 7 for the correct DPI kit. 9. Install the rear channel bracket. 10.

NOTE: When converted to downflow position, the coil may protrude above the cabinet on some models. 8. Reinstall the evaporator coil with the horizontal panel on the left side. Note: Push the assembly completely to the rear to ensure the engagement of the upflow pan with the rear channel bracket. Horizontal Conversion Dedicated Downflow models are not suitable for horizontal application and must not be used for this type of installation. The only field modification required for conversion to “Horizontal Right-Hand” is the removal of the plastic knockouts in the horizontal panel drain connections. To prevent the horizontal drain pan from sweating in high humidity applications, it is recommended that a DPIH insulation accessory kit be used. NOTE: The DPIH insulation kit is not supplied with this product and should be purchased separately. See Table 8 for the correct DPIH kit. ARUF, ATUF or ARPF Model Insulation Kit 1729 / 1824 DPIH18-32 3030 / 1931 / 3636 DPIH36-42 3642 / 3743 / 4860 / 4961 DPH48-61 9. Install the “J” bracket (removed in step 2) to support the upflow pan to the tie channel. 10. Attach all panels and the metering device. Condensate Removal The coil drain pan has a primary and an optional secondary drain with 3/4" NPT female connections. The connectors required can be 3/4" NPT male either PVC, CPVC or metal pipe and should be hand tightened to a torque of approximately 37 in-lbs. to prevent damage to the drain pan connection. An insertion depth between .355 to .485 inches (3-5 turns) should be expected at this torque. Use the female (3/4 fpt) threaded fitting that protrudes outside of the enclosure for external connections. Table 8 1. Ensure drain pan hole is NOT obstructed. The following describes converting to “Horizontal Left-Hand”. Conversion to downflow MUST be performed in an area that allows access to all sides prior to placing the air handler in its 2. To prevent potential sweating and dripping on to finished space, it may be necessary to insulate the condensate 8 drain line located inside the building. Use Armaflex® or similar material. A Secondary Condensate Drain Connection has been provided for areas where the building codes require it. Pitch the drain line 1/4" per foot to provide free drainage. Insulate drain lines located inside the building to prevent sweating. Install a condensate trap to ensure proper drainage. If the secondary drain line is required, run the line separately from the primary drain and end it where it can be easily seen. NOTE: Water coming from this line means the coil primary drain is plugged and needs clearing. Therefore, a removal pump or float switch must not contain any of these materials. Tip: Priming the “P” trap may avoid improper draining at the initial installation and at the beginning of the cooling season. When coils are installed above ceilings, or in other locations where damage from condensate overflow may occur, it is MANDATORY to install a field fabricated auxiliary drain pan under the coil cabinet enclosure. Drain lines from the auxiliary pan must be installed and terminated so that the homeowner can see water discharges. ACHIEVING 2% LOW LEAKAGE RATE CAUTION Ensure that the Neoprene gasket with PSA remains intact on all surfaces that the access panels are secured to. These surfaces are the entire length of the wrapper and areas between the upper tie plate, upper and lower access panels. Be sure that upper access panel breaker insert gasket is intact and also flowrator gasket is installed on the lower access panel. An additional drain hole cover is required. If secondary drain is not installed, the secondary access must be plugged. The installation must include a “P” style trap that is located as close as is practical to the evaporator coil. See Figure 7 for details of a typical condensate line “P” trap. NOTE: Trapped lines are required by many local codes. In the absence of any prevailing local codes, please refer to the requirements listed in the Uniform Mechanical Building Code. A drain trap in a draw-through application prevents air from being drawn back through the drain line during fan operation thus preventing condensate from draining, and if connected to a sewer line to prevent sewer gases from being drawn into the airstream during blower operation. Field experience has shown condensate drain traps with an open vertical Tee between the air handler and the condensate drain trap can improve condensate drainage in some applications, but may cause excessive air discharge out of the open Tee. Goodman® does not prohibit this type of drain but we also do not recommend it due to the resulting air leakage. Regardless of the condensate drain design used, it is the installer’s responsibility to ensure the condensate drain system is of sufficient design to ensure proper condensate removal from the coil drain pan. ATUF/ARUF/ARPF/ADPF MOTOR (Motor Speed Adjustment) The motors in all ATUF, ARUF, ARPF and ADPF motors are multi-speed PSC motors. The color of the wire coming from the motor to the “COM” terminal on the control board defines in which speed the motor will operate. The black wire represents high speed, the red wire represents low speed, and the blue wire (select models only) represents medium speed. To change speeds, remove the wire attached to the “COM” terminal on the control board, and swap it with the wire (on terminal “M1” or “M2”) with the color that will give the desired speed. NOTE: In some models, not all speed taps are allowable for certain electric heat applications. Refer to air handler Series and Ratings plate for minimum speed. Drain Connection Air Handler 2" MIN. POSITIVE LIQUID SEAL REQUIRED AT TRAP 3" MIN. Figure 7 Use of a condensate removal pump is permitted when necessary. This condensate pump should have provisions for shutting off the control voltage should a blocked drain occur. A trap must be installed between the unit and the condensate pump. IMPORTANT NOTE: The evaporator coil is coated with oils that may dissolve styrofoam and certain types of plastics. 9 CFM deliverd against External Static Pressure Model ARUF172916 ARUF182416 ARUF193116 ARUF303016 ARUF363616 Speed 0.2" 0.3" 0.4" 0.5" 1155 1090 1025 950 895 Med. 940 890 860 815 755 Low 695 665 650 610 550 High 1155 1090 1025 950 895 Low 695 665 650 610 550 Med. 940 890 860 815 755 High 1,700 1,660 1,625 1,545 1,505 1,345 ARUF486016 ARUF496116 Speed ADPF18241/16 ARPF36421* ARPF37431* ARPF48601* ARPF49611* 0.5" 895 Med. 940 890 860 815 755 650 610 550 Med. 1,500 1,440 1,400 1,350 1025 965 915 Low 1,370 1,300 1,250 1,230 1,220 Med. 860 825 780 750 680 High 2,150 2,120 2,070 2,000 1,940 Med. 1,940 1,930 1,905 1,860 1,790 Low 1,610 1,600 1,590 1,575 1,550 Low 600 570 545 500 465 High 1385 1315 1240 1155 1065 Med. 1340 1290 1230 1140 1050 Low 1075 1030 980 910 840 High 1310 1240 1155 1090 1020 Med. 1270 1210 1140 1075 980 Low 1045 1005 955 885 805 Med. 1700 1500 1330 1660 1440 1300 1625 1400 1250 1545 1350 1230 ADPF30421/16 ADPF48601/16 NOTE: Assumes dry coil with filter in place; SCFM correction for wet coil = 4% (208V/240V) Model Speed CFM deliverd against External Static Pressure 0.1" 0.2" 0.3" 0.4" 0.5" High 1155 1090 1025 950 895 Med. 875 830 790 750 715 1220 Low 640 610 570 535 490 High 1135 1085 1025 965 915 Med. 860 825 780 750 680 600 570 545 500 465 1505 ATUF182416 1345 High 2065 2000 1925 1860 1780 Med. 1685 1635 1550 1470 1410 ATUF193116 Low 1490 1425 1345 1280 1205 Low High 2150 2120 2070 2000 1940 High 1455 1385 1330 1205 1090 1050 Med. 1940 1930 1905 1860 1790 Med. 1340 1290 1230 1140 Low 1610 1600 1590 1575 1550 Low 1075 1030 980 910 840 High 2150 2105 2040 1970 1880 High 1345 1290 1230 1150 1070 Med. 1270 1210 1140 1075 980 Low 1045 1005 955 885 805 High 1700 1680 1645 1610 1535 Med. 1500 1480 1440 1380 1325 Low 135 1320 1275 1230 1195 High 2065 2000 1925 1860 1780 Med. 1960 1935 1895 1825 1750 Low 1670 1625 1585 1525 1455 ATUF303016 ATUF363616 Speed 0.2" 0.3" 0.4" High 1155 1090 1025 950 895 940 890 860 815 755 695 665 650 610 ARUF374316 0.5" Med.

Examples include single-stage cooling and heat pump with single or two-stage electric heating. All these configurations can be applied with convenient connections to outdoor thermostat applications. The following sections will be detailed: • Single-Stage Cooling (GMC Thermostat Part #CHT18-60 or equivalent.) • Heat Pump (GMC Thermostat Part #18-60 or equivalent) Each diagram details the connections between room thermostat and ASPF air handlers, and the connections between the ASPF air handlers and the Condensing Unit (or Heat Pump) with optional connections to Outdoor Thermostats. For each configuration, refer to the explanation of the proper jumper(s) to remove for the corresponding blower speed that will result in the programmed ECM™ motor. IMPORTANT: WHEN MATCHING THE ASPF AIR HANDLERS TO A SINGLE SPEED COOLING OR HEAT PUMP UNIT, REMEMBER TO CONNECT “Y” FROM THE THERMOSTAT TO THE “Y2” ON THE LOW VOLTAGE TERMINAL BOARD. An equivalent thermostat can be used in place of the Goodman thermostat part number. The GMC thermostats that listed are mercury type thermostats. WARNING HIGH VOLTAGE!
