POINTS TO REMEMBER WHEN INSTALLING
1) Install the indoor unit in a location that can withstand the weight and vibration of the unit.
2) Leave space (or a service port) for servicing the refrigerant piping, drain piping and electrical
wiring.
*Installation service space is shown on " DIMENSIONS ".
3) Be careful when installing the indoor unit in the following places.
[Installation precautions]
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 desks, chairs, etc.
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 shop and office
is a warehouse, parking lot, etc., the surface
temperature of the flooring will become low
and the radiation of cold from the floor will
increase.
In this case, your feet will feel cold even if the
room temperature is suitable.
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.
