CARBON MONOXIDE POISONING HAZARD

Special Warning for Installation of Furnace or Air Handling Units in

Enclosed Areas such as Garages, Utility Rooms or Parking Areas

Carbon monoxide producing devices (such as an automobile, space

heater, gas water heater, etc.) should not be operated in enclosed areas

such as unventilated garages, utility rooms or parking areas because of

the danger of carbon monoxide (CO) poisoning resulting from the exhaust

emissions. If a furnace or air handler is installed in an enclosed area such

as a garage, utility room or parking area and a carbon monoxide producing

device is operated therein, there must be adequate, direct outside

ventilation.

This ventilation is necessary to avoid the danger of CO poisoning which

can occur if a carbon monoxide producing device continues to operate in

the enclosed area. Carbon monoxide emissions can be (re)circulated

throughout the structure if the furnace or air handler is operating in any

mode.

CO can cause serious illness including permanent brain damage or death.

If replacing an air handler, the system must be manufacturer

approved and Air-Conditioning, Heating, and Refrigeration

Institute (AHRI) matched. NOTE: Installation of unmatched

systems is strongly discouraged.

Pre-Installation Instructions

Carefully read all instructions for the installation prior to in-

stalling product. Make sure each step or procedure is under-

stood and any special considerations are taken into account

before starting installation. Assemble all tools, hardware

and supplies needed to complete the installation. Some items

may need to be purchased locally. Make sure everything

needed to install the product is on hand before starting.

Location

NOTE: Air handlers are designed for indoor installation

only.

Give special consideration to minimizing the length of refrig-

erant tubing when installing air handlers. Refer to Remote

Cooling/Heat Pump Service Manual, TP-106 Long Line Set

Application R-22 or TP-107 Long Line Set Application R-410A

for guidelines. The unit clearance from a combustible sur-

face may be 0". However, service clearance is to take prece-

dence. In addition allow a minimum of 24" in front of the unit

for service clearance.

Do not install the air handler in a location that violates the

instructions provided with the condenser.

If the unit is located in an area with high ambient temperature

and/or high humidity the air handler maybe subject to nui-

sance sweating of the casing. On these installations a wrap

of 2” fiberglass insulation with a vapor barrier is recom-

mended.

Consult all appropriate regulatory codes prior to determining

final clearances. When installing this unit in an area that may

become wet, elevate the unit with a sturdy, non-porous ma-

terial. In installations that may lead to physical damage (i.e. a

garage) it is advised to install a protective barrier to prevent

such damage.

Ductwork

This air handler is designed for a complete supply and return

ductwork system.

Do not operate this product without all the ductwork

attached.

To ensure correct system performance, the ductwork is to be

sized to accommodate 375-425 CFM per ton of cooling with

the static pressure not to exceed .5" WC. Inadequate duct

work that restricts airflow can result in improper performance

and compressor or heater failure. Ductwork is to be con-

structed in a manner that limits restrictions and maintains

suitable air velocity. Ductwork is to be sealed to the unit in a

manner that will prevent leakage.

Return Ductwork

DO NOT TERMINATE THE RETURN DUCTWORK IN AN

AREA THAT CAN INTRODUCE TOXIC, OR OBJECTION-

ABLE FUMES/ODORS INTO THE DUCTWORK. The return

ductwork is to be introduced into the air handler bottom (upflow

configuration).

Return Air Filters

Each installation must include a return air filter. This filtering

may be performed at the air handler or externally such as a

return air filter grille. Air handlers mounted in the downflow

orientation, including “B” series, require external filtering. A

washable filter is available as an accessory. To ensure opti-

mum performance frequent filter cleaning is advised. Refer

to Table 1 for the appropriate filter.

Electric Heat

Refer to this manual in combination with the instructions pro-

vided with the heat kit for the correct installation procedure.

The air handlers listed in this manual do not have factory

installed electric heat. Electric heat is available as an acces-

sory. If installing this option, the ONLY heat kits that can be

used are the HKR series.

NOTE: The Amana® brand EHK, ECB, EDB, and EDK kits

are NOT approved for use with these air handlers.

The heating mode temperature rise is dependent upon the

system airflow, the supply voltage, and the heat kit size (kW)

selected. Use Tables 2, 3, and 4 to determine the tempera-

ture rise (ºF).

Wire size is important to the operation of your equipment.

Use the following check list when selecting the appropriate

wire size for your unit.

•Wire size must carry the Minimum Circuit Ampac-

ity (MCA).

• Refer to the NEC (USA) or CSA (Canada) for wire siz-

ing. 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.

Refer to the latest edition of the National Electric Code

or in Canada the Canadian Electric Code when deter-

mining 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

Maximum Overcurrent Protection (MOP)

Every installation must include an NEC (USA) or CEC

(Canada) approved overcurrent protection device. Also,

check with local or state codes for any special regional re-

quirements.

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.

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 con-

duit, 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 en-

closed in conduit. Consult your local codes.

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 cav-

ity. 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 con-

nectors or other NEC or CEC approved means.

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.

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 al-

low the heat kit circuit breaker(s) to be installed. See the

HKR Installation Instructions for further details. The air han-

dler wires and supply wires are installed directly onto the HKR

circuit breaker(s) as shown in the HKR Installation Manual

and wiring diagram.

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 con-

nections are determined by whether the outdoor unit is a con-

denser or heat pump. The 24V-control voltage connects the

air handler to the room thermostat and condenser. Low volt-

age wiring is to be copper conductors. A minimum of 18AWG

must be used for installations up to 50’ and 16AWG for in-

stallations over 50’. Low voltage wiring can be connected

through the top of the cabinet or either side. See the “Ther-

mostat Wiring” section of this manual for typical low voltage

wiring connections.

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.

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.

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.

CAUTION

Special Instructions

This coil comes equipped with a check style flowrator for re-

frigerant 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 mix-

matched 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 proce-

dure shown below.

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.

1. Loosen the 13/16 nut 1 TURN ONLY to allow high pres-

sure tracer gas to escape. No gas indicates a possible

leak.

2. After the gas has escaped, remove the nut and discard

the black or brass cap.

3. Remove the check piston to verify it is correct and then

replace the piston. See piston kit chart in instructions.

4. Use a tube cutter to remove the spin closure on the

suction line.

3. Remove the flowrator from the lower left side access

panel and slide out the evaporator coil and horizontal

drain pan.

4. Remove the gasket from the horizontal pan drain con-

nections.

5. Remove the oval shaped plastic plug from the left side

access panel. Remove the oval shaped rubber gasket

seal from the lower right side access panel.

6. The drain connections for the horizontal pan are sealed

with a thin coating of plastic. Carefully knock out this

plastic seal with a screwdriver and hammer. Note: The

upper drain will become the secondary drain which

is mandatory in many municipalities .

7. Install the plastic plug removed in step 5 to the right

side lower access panel and the oval shaped rubber

gasket to the lower left access panel.

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.

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 re-

quired can be 3/4" NPT male either PVC, CPVC or metal

pipe and should be hand tightened to a torque of approxi-

mately 37 in-lbs. to prevent damage to the drain pan connec-

tion. 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.

1. Ensure drain pan hole is NOT obstructed.

2. To prevent potential sweating and dripping on to finished

space, it may be necessary to insulate the condensate

drain line located inside the building. Use Armaflex® or

similar material.

A Secondary Condensate Drain Connection has been pro-

vided 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.

CAUTION

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 conden-

sate 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 leak-

age. 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.

Figure 7

Use of a condensate removal pump is permitted when nec-

essary. 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 conden-

sate pump.

IMPORTANT NOTE: The evaporator coil is coated with oils

that may dissolve styrofoam and certain types of plastics.

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

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 be-

tween the upper tie plate, upper and lower access panels.

Be sure that upper access panel breaker insert gasket is in-

tact and also flowrator gasket is installed on the lower ac-

cess panel. An additional drain hole cover is required.

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 repre-

sents 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.

ASPF Motor

The ASPF air handler features an energy efficient blower

motor. The motor is a constant torque motor with very low

power consumption. The motor is energized by 24 VAC. Ad-

just the CFM by changing the 24 VAC leads to the desired

speed on the terminal block.

The ASPF motor blower speed is programmed to deliver ad-

equate airflow at rated external static pressure and with 60

second off time delay. For details, refer to the specification

sheet applicable to your model.

CFM Delivery

Table 13 shows the CFM speed tap settings for the ASPF.

Thermostats

NOTE: Second Stage heat can be accomplished by multi-

stage heating thermostat or the addition of an outdoor

thermostat as shown in Figures 10 and 11.

Goodman® part number CHT18-60 is a single-stage cool and

single-stage heat thermostat.

Goodman® part number HPT18-60 is a single-stage cool,

two-stage heat pump thermostat. The first stage is heat pump

heating and the second stage is optional electric heat.

If additional features are desired, such as digital or program-

mable capabilities, these thermostats are commercially avail-

able. Follow the thermostat manufacturer’s instruction for in-

stallation.

ASPF THERMOSTAT CONNECTIONS

The following composite wiring diagrams detail various configurations in which the ASPF air handlers can be used. Ex-

amples 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 COOL-

ING 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.
