Installation of Unit
36 Air-to-Water Heat Pump
Installation at Seaside
Seasonal Wind and Cautions in Winter
1. Unit should not be installed in areas where corrosive gases, such as acid or alkaline gas, are produced.
2. Do not install the unit where it could be exposed to sea wind (salty wind) directly. It can result corrosion
on the unit. Corrosion, particularly on the condenser and evaporator fins, could cause unit malfunc-
tion or inefficient performance.
3. If 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.
1. 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
1) If the unit is to be installed close to the seaside, direct exposure to the sea wind should be avoided.
Install the unit on the opposite side of the sea wind direction.
2) In case, to install the 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 unit.
• It should be keep more than 700 mm of space
between unit and the windbreak for easy
air flow.

• Sufficient measures are required in a snow area or severe cold area in winter so that unit 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 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 unit at the higher installation console by 500mm 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 unit by more than 100mm, 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 unit.
(If width of the frame is wider than that of the unit, snow may accumulate.)
2. Don't install the suction hole and discharge hole of the unit facing the seasonal wind.
