1. Selection of the best location
1) Indoor unit
• There should not be any heat source or
steam near the unit.
• There should not be any obstacles to
prevent the air circulation.
• A place where air circulation in the room will
be good.
• A place where drainage can be easily
obtained.
• A place where noise prevention is taken into
consideration.
• Do not install the unit near the door way.
• Ensure the spaces indicated by arrows from
the wall, ceiling, or other obstacles.
• The indoor unit must keep the maintenance
space.
2) Outdoor unit
• If an awning is built over the unit to prevent
direct sunlight or rain exposure, be careful
that heat radiation from the condenser is not
restricted.
• There should not be any animals or plants
which could be affected by hot air
discharged.
• Ensure the spaces indicated by arrows from
the wall, ceiling, fence or other obstacles.
