GENERAL INSTALLATION GUIDELINES

Oceanside Applications

Tie-Downs and Wind Restraints
• The strength of the Single Zone system frame is adequate to be used with field-provided wind restraint 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 re-
straint system.
Oceanside Applications
Use of a Windbreak to Shield from Sea Wind
Ocean winds may cause corrosion, particularly on the condenser and
evaporator fins, which, in turn could cause product malfunction or ineffi-
cient performance.
• 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.
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.
