- In case the result of calculation exceeds the limiting concentration, perform
the same calculations by shifting to the second smallest, and the third small-
est rooms until at last the result is below the limiting concentration.
In case the concentration exceeds the limit
When the concentration exceeds the limit, change original plan or take
one of the countermeasures shown below:
• Countermeasure 1
Provide opening for ventilation.
Provide 0.15% or more opening to floor space both above and below
door, or provide opening without door.
• Countermeasure 2
Provide gas leak alarm linked with mechanical ventilator.
Reducing the outdoor refrigerant qty.

CAUTION
• Air conditioners 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
anticorrosion treatment on the heat exchanger.

In case, to install the outdoor unit on the seaside, set up a windbreak
not to be exposed to the sea wind.
Windbreak
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 70 cm of space between outdoor unit
and the windbreak for easy air flow.
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
