• 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 will need to be applied to the outdoor
unit at oceanside locations.
Ocean winds will cause corrosion, particularly on the condenser and

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 in the figure at right.
