Installation at Seaside
CAUTION
!
• AWHP should not be installed in areas where corrosive gases, such as acid or alkaline gas,
are produced.
• 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.
• If outdoor unit is installed close to the seaside, it should avoid direct exposure to the sea
wind. Otherwise it needs additional anti-corrosion treatment on the heat exchanger.
Selecting the location(Outdoor Unit)
- 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
- In case, to install the outdoor unit on the seaside, set up a windbreak not to be exposed to the
sea wind.

- Select a well-drained place.
Periodic ( more than once/year ) cleaning of the dust or salt particles stuck on the heat
exchanger by using water.
- If you can't meet above guide line in the seaside installation, please contact your supplier for the
additional anti-corrosion treatment.
Seasonal wind and cautions in winter
• 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 500 mm 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 100 mm, always
remove snow for operation.
- 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)
- Don't install the suction hole and discharge hole of the Outdoor Unit facing the seasonal wind.
Sea wind
- 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 700 mm of space
between outdoor unit and the windbreak for easy
