Rooftop Installations
If the outdoor unit is installed on a roof structure, be sure to level the unit. Ensure the roof structure and anchoring method are adequate for
the unit location. Consult local codes regarding rooftop mounting.

Oceanside Installation Precautions
• 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.
Avoid installing the outdoor unit where it would be directly exposed to
ocean winds.
Additional anti-corrosion treatment will need to be applied to the outdoor
unit at oceanside locations.
If the outdoor unit must be
placed in a location where it
would be subjected to direct
ocean winds, install a concrete
windbreaker strong enough to
block any winds. Windbreaker
height and width must be more
than 150% of the outdoor unit,
and be installed at least 27-1/2
inches away from the outdoor
unit to allow for airflow.
Ocean winds will cause corrosion, particularly on the condenser and

cient performance.
When deciding on a location to place the outdoor unit, be sure to choose an area where run-off from defrost will not accumulate and freeze on
sidewalks or driveways, which will create unsafe conditions. Properly install and insulate any drain hoses to prevent the hose from freezing, cracking,
leaking, and causing unsafe conditions from frozen condensate.
PLACEMENT CONSIDERATIONS
Planning for Snow and Ice, continued.
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.

If the building does not include lightning protection, the outdoor unit will be damaged from a lightning strike. Inform the customer of this possibility in
advance.
