18. Indoor unit installation precautions
NOTE: The information listed below are general precautions.
Some models also include items that do not apply.
18-1. Places where prohibited for use
• Places where there is a danger of combustible gas leakage.
• Places where sulfur gas, chlorine gas, acid, alkali, or other matter which effects equipment is gen-
erated.
• Places where there is a lot of oil splash and steam such as kitchen or machinery room.
• Places where machinery which generates high frequencies is used.
• Ocean beaches and other areas where there is a lot of salt.
• Places where carbon fibers or any kind of powder suspended in the air.
• Inside of vehicles, ships, and other conveyances.
• Places where voltage fluctuations are large such as a factory.
18-2. Points to remember when installing
• The product shall be installed at a place which can withstand the weight and vibration of the in-
door.
• To allow maintenance after refrigerant piping, drain piping, and the connection/installation of elec-
tric wiring, provide an maintenance space and an inspection port, as required.
Maintenance space is shown on "Dimensions" on page 35.
• Be careful when installing the unit at the following places.
Condition Contents Countermeasures (Reference)
When the
ceiling is high.
If the indoor unit is installed where the installation height
given in the installation manual is exceeded, the
temperature difference between the floor and ceiling of the
room will be large and the heating effect will be poor.
Moreover, even if the indoor unit is installed within the
installation height, a similar phenomena will occur when
installed in a room in which the doors are opened and
closed frequently and hot air circulation is obstructed by
furniture such as desks or chairs.
1. Switch the setting to the high
ceiling mode.
2. Install a circulator.
3. Arrange the furniture in the
room so that it does not
obstruct the hot air.
When lower
level directly
contacts the
outside air.
When the lower level of the room is a semi-open space
such as warehouse or parking lot the surface temperature
of the flooring will become low and the radiation of cold
from the floor will increase.
In this case, even if the room temperature is suitable, you
may feel the foot level is cold.
When the
airflow
distribution is
poor.
When an indoor unit is installed in a position where the
outlet airflow will directly contact people, a draft may be
felt.
In addition, when there are obstructions in the path of the
intake and outlet airflow, the air distribution may become
extremely bad.
1. Adjust the louver fins or take
other measures matched to the
site.
2. Change the indoor unit outlet.
