SAFETY INSTRUCTIONS
INSTALLATION - CONTINUED
Don’t install the unit where it’s directly exposed to ocean
winds.
Ocean winds may cause corrosion, particularly on the condenser and
evaporator ns, which, in turn could cause product malfunction or inef-
cient performance.
When installing the unit in a low-lying area, or a location that
is not level, use a raised concrete pad or concrete blocks to
provide a solid, level foundation.
This may prevent water damage and reduce abnormal vibration.
Properly insulate all cold surfaces to prevent “sweating.”
Cold surfaces such as uninsulated piping can generate condensate that
may drip and cause a slippery surface condition and/or water damage to
walls.
When installing the unit in a hospital, mechanical room, or
similar electromagnetic eld (EMF) sensitive environment,
provide sufcient protection against electrical noise.

cause a re, electric shock, physical injury or death. Follow the placement guidelines set forth in “Clearance Requirements”.
Install a fence to prevent vermin from crawling into the unit or unauthorized individuals from accessing it. Vermin and unauthorized individuals may
damage the unit. Follow the placement guidelines set forth in “Clearance Requirements”.
Select a location for installing the outdoor unit that will meet the following conditions:
• Where there is enough structural strength to bear the weight of the unit.
• A location that allows for optimum air flow and is easily accessible for inspection, maintenance, and service.
• Where piping between the outdoor unit and indoor unit is within allowable limits.
• Include space for drainage to ensure condensate flows properly out of the unit when it is in heating mode. Avoid placing the outdoor unit in
a low-lying area where water could accumulate.
• If the outdoor unit is installed in a highly humid environment (near an ocean, lake, etc.), ensure that the site is well-ventilated and has a lot
of natural light (Example: Install on a rooftop).
Dont’s
• Where it will be subjected to direct thermal radiation from other heat sources, or an area that would expose the outdoor unit to heat or steam
like discharge from boiler stacks, chimneys, steam relief ports, other air conditioning units, kitchen vents, plumbing vents, and other sources
of extreme temperatures.
• Where high-frequency electrical noise / electromagnetic waves will affect operation.
• Where operating sound from the unit will disturb inhabitants of surrounding buildings.
• Where the unit will be exposed to direct, strong winds.
• Where the discharge of one outdoor unit will blow into the inlet side of an adjacent unit (when installing multiple outdoor units).
Planning for Snow and Ice
To ensure the outdoor unit operates properly, certain measures are required in locations where there is a possibility of heavy snowfall or
severe windchill or cold:
1. Prepare for severe winter wind chills and heavy snowfall, even in areas of the country where these are unusual phenomena.
2. Position the outdoor unit so that its airflow fans are not buried by direct, heavy snowfall. If snow piles up and blocks the airflow, the sys-
tem may malfunction.
3. Remove any snow that has accumulated four (4) inches or more on the top of the outdoor unit.
4. In climates that may experience significant snow buildup, mount the outdoor unit on a raised, field-provided platform or stand. The raised
support platform must be high enough to allow the unit to remain above possible snow drifts, and must be higher than the maximum antici-
pated snowfall for the location.
5. Design the mounting base to prevent snow accumulation on the platform in front or back of the unit frame.
6. Provide a field fabricated snow protection hood to keep snow and ice and/or drifting snow from accumulating on the coil surfaces.
7. To prevent snow and heavy rain from entering the outdoor unit, install the condenser air inlets and outlets facing away from direct
winds.
8. Consider tie-down requirements in case of high winds or where required by local codes.

Planning for Snow and Ice, continued.
The indoor unit may take longer to provide heat, or heating performance will be reduced in winter if the unit is installed in the following locations:
Choose an area where run-off water from defrost cycle will not accumulate and freeze on sidewalks or driveways. Properly install and insulate any
drain hoses to prevent the hose from freezing, cracking, leaking, and damaging the outdoor unit.
• In a narrow, shady location.
• Near a location that has a lot of ground moisture.
• In a highly humid environment.
• In an area in which condensate does not drain properly.
Outdoor Unit Location Selection
When deciding on a location to place the outdoor unit, be sure to choose an area where run-off water from defrost cycle will not accumulate and
freeze on sidewalks or driveways, which may create unsafe conditions. Properly install and insulate any drain hoses to prevent the hose from freez-
ing, cracking, leaking, and causing unsafe conditions from frozen condensate.
Tie-Downs and Lightning Protection
Tie-Downs
• The strength of the roof must be checked before installing the
outdoor units.
• If the installation site is prone to high winds or earthquakes, when
installing on the wall or roof, securely anchor the mounting base
using a field-provided tie-down configuration approved by a local
professional engineer.
• The overall tie-down configuration must be approved by a local
professional engineer.
Always refer to local code when using a wind restraint system.
Lightning Protection
• To protect the outdoor unit from lightning, it must be placed within
the specified lightning safety zone.
• Power cable and communication cable must be installed five (5) feet away from lightning rod.
• A high-resistance ground system must be included to protect against induced lightning or indirect strike.

GENERAL INSTALLATION GUIDELINES
• Avoid installing the outdoor unit where it would be directly
exposed to ocean winds.
• Install the outdoor unit on the side of the building opposite from
direct ocean winds.
• Select a location with good drainage.
• Periodically clean dust or salt particles off of the heat exchanger
with water.
• If the outdoor unit must be placed in a location where it would
be subjected to direct ocean winds, install a concrete windbreak
strong enough to block any winds.
• Windbreak must be more than 150% of the outdoor unit’s height.
There must be 2 to 3-1/2 inches of clearance between the outdoor
unit and the windbreaker for purposes of air flow.
Additional anti-corrosion treatment may need to be applied to the out-
door unit at oceanside locations.
Ocean winds may cause corrosion, particularly on the condenser and
evaporator ns, which, in turn could cause product malfunction or inef-
cient performance.
Oceanside Applications
Use of a Windbreak to Shield from Sea Wind
Use of a Building to Shield from Sea Wind
If a windbreak is not possible, a building or larger structure must be
used to shield the outdoor unit from direct exposure to the sea wind.
The unit must be placed on the side of the building directly opposite
to the direction of the wind as shown at right.

Do not place the unit where animals
and/or plants will be in the path of the warm
air, or where the warm air and/or noise will
disturb neighbors.
If the outdoor unit is installed between standard and minimum clearances, capacity decreases approximately 10%.
Minimum Clearance Requirements for Single Fan Outdoor Units
Proper clearance for the outdoor unit coil is critical for proper operation. When installing the outdoor unit, consider service, inlet and outlet,
and minimum allowable space requirements as illustrated in the diagrams below.
Specific clearance requirements in the diagram below are for single fan outdoor units. Figure below shows the overall minimum clearances
that must be observed for safe operation and adequate airflow around the outdoor unit.
When placing the outdoor unit under an overhang, awning, sunroof or other “roof-like structure”, observe the clearance requirements (as
shown in Cases 1 and 2) for height in relation to the unit. This clearance ensures that heat radiation from the condenser is not restricted
around the unit.
Adhere to all clearance requirements if installing the unit on a roof. Be sure to level the unit and ensure that the unit is adequately anchored.
Consult local codes for rooftop mounting requirements. To have successful service access to the outdoor unit, see figure below for minimum
spacing. When installing multiple outdoor units, see Cases 4 and 5 in the figure below for correct spacing requirements. Outdoor unit fans
draw air from the back of the unit and discharge out the front. Place units back to back and front to front.

GENERAL INSTALLATION GUIDELINES
Required Indoor Unit Clearances
Follow recommended best practices when choosing an indoor location
for the single zone indoor unit.
Dos
• Follow the table at right for minimum clearance of indoor unit from
the top of the unit to the ceiling.
• Clearance gap between any wall or enclosure and the left or right
side of the unit must be greater than 4 inches. Ensure there is
sufficient maintenance space.
• Unit must be at least 6.5 feet from the floor for adequate clearance.
• Place the unit where drainage can be obtained easily. Condensa-
tion drain must be conveniently routed away from the unit.
• Locate the indoor unit in a location where it can be easily connect-
ed to the outdoor unit within allowable limits.
• Use a metal detector to locate studs in the walls. Anchor unit
following stud location to prevent damage to the wall.
Dont’s
• Do not install the unit near a heat or steam source, or where consid-
erable amounts of oil, iron powder, or flour are used. (These materi-
als may generate condensate, cause a reduction in heat exchanger
efficiency, or the drain to malfunction. If this is a potential problem,
install a ventilation fan large enough to vent out these materials.)
• Do not install near doorway.
• Avoid installing the unit near high-frequency generators.
The unit must not be installed where sulfuric acid and ammable or
corrosive gases are generated, vented into, or stored. There is risk of
re, explosion, and physical injury or death.
The unit may be damaged, may malfunction, and / or will
not operate as designed if installed in any of the conditions
listed.
Installing in an Area Exposed to Unconditioned Air
In some installation applications, areas (floors, walls) in some rooms may be exposed to unconditioned air (room may be above or next to an
unheated garage or storeroom). To countermeasure:
• Verify that carpet is or will be installed (carpet may increase the temperature by three [3] degrees).
• Add insulation between the floor joists.
• Install radiant heat or another type of heating system to the floor.
Install a ventilation fan

Dont’s
• Ensure there are no obstacles to air circulation around the unit; keep
proper distances from ceilings, doorways, floor, walls, etc.
• Do not install in an area where operation sound will disturb occu-
pants--place the unit where noise prevention is taken into consid-
eration
• Indoor units (IDUs) must not be placed in an environment where the IDUs may be exposed to harmful volatile organic compounds (VOCs)
or in environments where there is improper air make up or supply or inadequate ventilation. If there are concerns about VOCs in the envi-
ronment where the IDUs are installed, proper air make up or supply and/or adequate ventilation must be provided. Additionally, in buildings
where IDUs will be exposed to VOCs, consider a third party factory-applied epoxy coating to the fan coils for each IDU where the entire coil
is dipped, not sprayed.
• If the unit is installed near a body of water, the installation parts are at risk of corroding. Appropriate anti-corrosion methods must be taken for
the unit and all installation parts.
