[Installation precautions]
When When the wall mounting type was installed
installation in a bedroom, living room, or other quiet
environment is place, the sound of the refrigerant flow may
quiet be sensed as noise and must be taken into
accunt.
When In the case of the ceiling chamber system
installing duct (duct is not installed at indoor unit inlet
type in ceiling side and room air is sucked into the indoor
chamber unit through the inside of the ceiling), the
system thermistor inside the indoor unit may not
correctly detect the room temperature.
Heating operation: Room is not heated
because the indoor unit is easily turned off by
the thermostat.
Cooling operation: Room is too cold because
the indoor unit is difficult to turn off by the
thermostat.
When the Cooling operation does not cool the room
outlet air is and heating operation does not heat the room
sucked in at because the short circuited indoor unit is not
duct type turned on by the thermostat.
When using Signals may not be received when using it in

Countermeasures (Reference)
1) Plan installation of a model
with external expansion
valve.
2) Plan installation of a branch
box farther from indoor
unit.
3) Plan installation using
another air conditioner.
1) Replace the indoor unit
thermistor with a Remote
sensor unit (optional
parts) and install the
sensor where the room
temperature can be
correctly detected
1) Reconsider the ventilation
port construction
2) Replace the indoor unit
thermistor with a Remote
sensor unit (optional
parts) and install the
sensor where the room
temperature can be
correctly detected.
1) Turn on the fluorescent
lamp and check if the
indoor unitreceives the
signals from the remote
controller.
If the indoor unit does
notreceive the signals,
consult an authorized
service personnel.
1) The inverter type should
be installed at a sufficient
distance from these
equipments.
