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 monox i de produc ing 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 structur e if the furnace or air handle r is operating in any mode.

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

WARNING

Do not connect to or use any device that is not design certified by Goodman for use with this unit. Serious property damage, personal injury, reduced unit perform ance and/O R haza rdou s cond itio ns m ay resu lt from the use of such non-approved devices.

CAUTION

Have your contractor identify all the various cutoff switches and devices that service this unit. Know where the switch is that will cut off energy to the heating system in the event of overheating.

Special Notes for European Consumers:

Do not dispose of this product as unsorted municipal waste. Collection of such waste for special treatment is necessary. It is strictly prohibited to dispose of this unit in domestic household waste. Disposal options:

1. Some municipalities have established collection systems to collect electronic waste for disposal.

2. Your purchase point retailer (or manufacturer) may take back the unit for disposal.

3. Used products contain valuable resources and can be sold to scrap metal dealers.

Illegal disposal in forests and landscapes endanger your health and the environment. Hazardous materials leak into ground water.

SHIPPING INSPECTION

Upon receiving the product, inspect it for damage from shipment. Shipping damage, and subsequent investigation is the responsibility of the carrier. Verify the model number, specifications, electrical characteristics, and accessories are correct prior to installation. The distributor or manufacturer will not accept claims from dealers for transportation damage or installation of incorrectly shipped units.

APPLICATION INFORMATION

This ceiling mount air handler is available in cooling capacities of 1.0, 1.5, 2, 2.5, 3.0, 3.5, 4.0 and 6.0 nominal tons of cooling. Electric heat models are available in capacities of 0, 5, 6, 8 and 10 kW.

The unit is designed to be installed in a horizontal position

above a dropped ceiling. Do NOT install this unit outside

the structure. These models are designed for INDOOR USE ONLY.

PRE-INSTALLATION CONSIDERATIONS

Carefully read all instructions for the installation prior to installing product. Make sure each step or procedure is understood 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.

Before attempting any installation, the following points should be considered:

• Structural strength of supporting members

• Clearances and provision for servicing

• Power supply and wiring - Routing of wires must be arranged so the control board cover is fixed properly. If not, a possibility of overheating, fire or electrical shock may occur at the connection point of the terminal.

• Air duct connections - Ductwork should be fabricated in accordance with local codes and sized to accommodate 375-425 CFM per ton of cooling with the static pressure not to exceed 0.5” W.C. Inadequate ductwork that restricts airflow can result in improper performance and compressor or heater failure.

• Drain facilities and connections

• Installation of unit must be, at a minimum, of 91” (2.3m) above the floor.

• Electrical installations must be in accordance with local national wiring standards, regulations and this installation instruction. An independent circuit and single

outlet must be used. If installed without the proper electrical circuit capacity, or installed defectively, possibility of electrical shock or fire may occur.

• To ensure proper performance of unit, use the specified cable, and clamp the cable securely to prevent disconnection as this will cause overheating or fire at the connection.

• An all-pole disconnect switch, having a contact sepa-

ration of at least 3mm in all poles, should be connected in the fixed wiring.

3. The installation to ceilings varies with construction. Con-

sult construction personnel for the specific procedures.

4. Install pipes and lines in the ceiling after completion of

the installation of the ACNF air handler. The first consideration of installation is to determine the direction of the pipes. When installing in a ceiling, position the refrigerant pipes, drain pipes, indoor and outdoor lines to the connections before hanging the unit.

5. Install the hanging screw bolts.

6. After the selection of installation location, position the

refrigerant pipes, drain pipes, indoor and outdoor lines to the connections before hanging the unit.

7. Attach the hanging screw bolts.

NOTE: To prevent interference, keep indoor unit, outdoor

unit, power supply wiring and transmission wiring at least 39” (1 meter) from televisions and radios.

INSTALLATION ORDER

Install your unit in the following order:

1. Select the mounting locations.

2. Install the indoor unit.

3. Instal the outdoor unit.

4. Install the connecting pipe

5. Connect the drain pipe.

6. Wiring.

7. Test operation.

LAYOUT FOR CEILING MOUNT AIR HANDLERS

NOTE: The location of the unit is based on thorough consid-

eration of the PRE-INSTALLATION CHECK POINTS below:

NOTE: The minimum drain tilt is at least 1/100.

Installing the dust proof net and canvas air passage

1. Install the dust proof net according to the installation manual.

2. Install the canvas air passage underneath the dust proof net.

Duct Design

1. Air inlet/outlet ducts must be spaced to prevent air from the outlet from entering the air inlet.

3. When connecting the ductwork, install in a location where maintenance can be done easily.

4. The fan motor static pressure should correspond to the external static pressure.

5. When installed in a noise-sensitive setting, install an isolation booth and internal duct underlayer to help muffle the duct noise. (Figure 7.)

OUTDOOR UNIT INSTALLATION

The following are considerations before installing the outdoor unit.

• Install the outdoor unit on a rigid base to prevent noise

and vibration.

• Place the outdoor unit in such a manner to minimize restriction of discharge air.

• Protect the unit from prevailing winds. To ensure the

unit operates correctly, place the unit lengthwise along a wall or use a dust or shield plate.

• Install in a place where the unit is easily accessible

for installation and maintenance.

Moving and Installation Notes:

• The inlet of the unit should not be used as a “handle”

when moving the unit.

• Use caution when moving the unit with a sling, since the center of gravity is not in the unit’s physical cen-

ter.

• The fan should not be touched with hands or any foreign objects.

Figure 14A Figure 14B

• Do not lean the unit more than 45° or lay it on its side.
