Installation guide at the seaside

Seasonal wind and cautions in winter

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 malfunc-

tion or inefficient performance.

3. If outdoor unit is installed close to the seaside, it should avoid direct exposure to the sea wind. Otherwise it

needs additional anticorrosion treatment on the heat exchanger.

If you can’t meet above guide line in the seaside installation, please contact LG Electronics for the additional anticorrosion treatment.

2. Periodic ( more than once/year ) cleaning of the dust or salt particles stuck on the heat exchanger by using water

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.

2) In case, to install the outdoor unit on the seaside, set up a windbreak not to be exposed to the sea wind.

3) Select a well-drained place.

• It should be strong enough like concrete to prevent

the sea wind from the sea.

• The height and width should be more than 150% of

the outdoor unit.

• It should be keep more than 70 cm of space

between outdoor unit and the windbreak for easy

air flow.

• Sufficient measures are required in a snow area or severe cold area in winter so that product can be

operated well.

• Get ready for seasonal wind or snow in winter even in other areas.

• Install a suction and discharge duct not to let in snow or rain.

• Install the outdoor unit not to come in contact with snow directly. If snow piles up and freezes on the

air suction hole, the system may malfunction. If it is installed at snowy area, attach the hood to the

system.

• Install the outdoor unit at the higher installation console by 50cm than the average snowfall (annual average snowfall) if it

is installed at the area with much snowfall.

• Where snow accumulated on the upper part of the Outdoor Unit by more than 10cm, always remove snow for operation.

1. The height of H frame must be more than 2 times the snowfall and its width shall not exceed the width of the

product. (If width of the frame is wider than that of the product, snow may accumulate)

2. Don't install the suction hole and discharge hole of the Outdoor Unit facing the seasonal wind.
