Countermeasures (Reference)
1. Install the remote controller
where it will not be directly
exposed to the cold or hot air.
2. Install the remote controller
where it will not be directly
exposed to sunlight or strong
lighting.
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.
Turn on the fluorescent lamp and
check if the indoor unit receives the
signals from the remote controller.
If the indoor unit does not receive
the signals, consult an authorized
service personnel.
The inverter type should be
installed at a sufficient distance
from these equipments.
