Single Zone High Efciency Standard Wall Mount Engineering Manual

Due to our policy of continuous product innovation, some specications may change without notication.

• 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 outdoor

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.

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 Figure 31.
