6. To prevent snow and heavy rain from entering the outdoor unit, install the suction and discharge ducts
facing away from direct winds.
7. Additionally6, the following conditions should be taken into consideration when the unit operates in
defrost mode:
•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. (For example: Install on a rooftop.)
• Sidewalks or parking lots near
the outdoor unit may accumulate moisture after unit operates in
defrost mode that can turn into ice.
Installation location of the outdoor unit can affect indoor-unit operation. The indoor unit may take longer to
provide heat, or heating performance will be reduced in winter
in the outdoor unit is installed:
•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.
3.1.1 Ambient air conditions
NOTICE
Risk of exposure to improper environmental conditions. Can cause equipment damage.
• Avoid exposing the outdoor unit to steam, combustible gases, or other corrosive elements.
• Avoid exposing the unit to discharge from boiler stacks, chimneys, steam relief
ports, other air-
conditioning units, kitchen vents, plumbing vents, or substances that may degrade performance
or cause damage to the unit.
• When installing multiple outdoor units, avoid placing the units where discharge of one outdoor
unit will blow into the inlet
side of an adjacent unit.
3.1.2 Oceanside Applications
Using a Windbreak to Shield the Unit from Sea Wind
• Avoid installing the unit where it would be directly exposed to ocean w inds.
•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, see Figure 3-1 for windbreak location.
• T
he windbreak should 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 windbreak for purposes of flow.
NOTE
Ocean winds may cause corrosion, particularly on the condenser and
evaporator fins, which, in turn could cause product malfunction or inefficient
performance.
