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.

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.
WARNING
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.
CAUTION
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 ship-
ment. Shipping damage, and subsequent investigation is the
responsibility of the carrier. Verify the model number, speci-
fications, electrical characteristics, and accessories are cor-
rect 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 capaci-
ties 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 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.
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 termi-
nal.
• Air duct connections - Ductwork should be fabricated
in accordance with local codes and sized to accom-
modate 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 lo-
cal national wiring standards, regulations and this in-
stallation instruction. An independent circuit and single
outlet must be used. If installed without the proper
electrical circuit capacity, or installed defectively, pos-
sibility of electrical shock or fire may occur.
• To ensure proper performance of unit, use the speci-
fied 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 con-
nected in the fixed wiring.

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:
• Structural strength of supporting members
• Clearances and provision for servicing
• Power supply and wiring
• Air duct connections
• Drain facilities and connections
1. Before locating the unit on the dropped ceiling, ensure
the strength of the ceiling and beams is adequate to
support the weight involved. This is an important step
and the installers responsibility.
Installing the four (4) 3/8” (Ø 10) Hanging Screw Bolts
2. Mount the unit in a horizontal position above a dropped
ceiling of adequate strength with four 3/8” (Ø 10) hang-
ing screw bolts. Refer to the following figures for dis-
tance between the screw bolts.
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 con-
sideration of installation is to determine the direction of
the pipes. When installing in a ceiling, position the re-
frigerant 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: 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.
2. A dust filter is located on the indoor unit.

NOTES:
1. The indoor unit should not bear the connecting duct’s
weight.
2. Use the fire retardant canvas tie-in to prevent vibrating.
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 out-
door 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.

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