Installation at Seaside
CAUTION
!
• Unit should not be installed in areas where corrosive gases, such as acid or alkaline gas,
are produced.
• 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.
• 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.
Selecting the location
• 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.
Sea wind
• In case, to install the unit on the seaside, set up a windbreak not to be exposed to the sea wind.
Windbreak
Sea wind
• Select a well-drained place.
- If you can't meet above guide line in the seaside installation, please contact your supplier for
the additional anticorrosion treatment.
- Periodic ( more than once/year ) cleaning of the dust or salt particles stuck on the heat
exchanger by using water
Seasonal Wind and Cautions in Winter
• 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 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 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 unit. (If width of the frame is wider than that of the unit, snow may
accumulate.)
- Don't install the suction hole and discharge hole of the 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 unit.
- It should be keep more than 700 mm of space
between unit and the windbreak for easy air flow.
