Installation Manual 9
Installation of Indoor, Outdoor Unit
Seaside Applications and Installation
1.Air conditioners should not be installed in areas where corrosive gases, such as acid or alkaline gas, are produced.
2.Do not install the product where it could be exposed to sea wind (salty wind) directly. It can result corrosion on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient performance.
3.If outdoor unit is installed close to the seaside, it should avoid direct exposure to the sea wind.
1.Selecting the location(Outdoor Unit)
1)If the outdoor unit is to be installed close to the seaside, direct exposure to the sea wind should be avoided. Install the outdoor unit on the opposite side of the sea wind direction.
Sea wind |
Sea wind |
2) In case, to install the outdoor unit on the seaside, set up a windbreaker/barrier, to lessen the unit's exposure to sea air
Windbreaker/Barrier
Sea wind
3) Select a well-drained place.
•It should be strong enough (like concrete) to obstruct the wind from the sea.
•The height and width should be more than 150% of the outdoor unit.
•A minimum of 70cm (27 1/16 inches)
of space between outdoor unit and the windbreak for easy air flow.
Periodic ( more than once/year ) cleaning of the dust or salt particles stuck on the heat exchanger using water is recommended.
