• Make sure that ventilation fan is enough to cover all noxious gases from this place.
• Ensure enough distance from the cooking room to install the air conditioner in such a place where it
may not suck oily steam.
2. Avoid installng air conditioner
in such places where
cooking oil or iron powder is
generated.
3. Avoid places where
inflammable gas is generated.
4. Avoid place where noxious gas is
generated.
5. Avoid places near high frequency
generators.
NOTICE
CAUTION :
