If the system does NOT operate properly except for the above
mentioned cases and none of the above mentioned malfunctions is
evident, investigate the system in accordance with the following
procedures.
Malfunction Measure
If a refrigerant leak
occurs (error code /
)
▪ Actions will be taken by the system. Do
NOT turn OFF the power supply.
▪ Notify your installer and report the
malfunction code.
If the system does not
operate at all.
▪ Check if there is no power failure. Wait
until power is restored. If power failure
occurs during operation, the system
automatically restarts immediately after
power is restored.
▪ Check if no fuse has blown or breaker is
activated. Change the fuse or reset the
breaker if necessary.
If the system goes into
fan only operation, but
as soon as it goes into
heating or cooling
operation, the system
stops.
▪ Check if air inlet or outlet of outdoor or
indoor unit is not blocked by obstacles.
Remove any obstacles and make sure
the air can flow freely.
▪ Check if the user interface display shows
on the home screen. Refer to the
installation and operation manual
delivered with the indoor unit.
The system operates
but cooling or heating
is insufficient.
▪ Check if air inlet or outlet of outdoor or
indoor unit is not blocked by obstacles.
Remove any obstacles and make sure
the air can flow freely.
▪ Check if the air filter is not clogged (refer
to "Maintenance" in the indoor unit
manual).
▪ Check the temperature setting.
▪ Check the fan speed setting on your user
interface.
▪ Check for open doors or windows. Close
doors and windows to prevent wind from
coming in.
▪ Check if there are too many occupants in
the room during cooling operation. Check
if the heat source of the room is
excessive.
▪ Check if direct sunlight enters the room.
Use curtains or blinds.
▪ Check if the air flow angle is proper.
After checking all the items above, if it is impossible to fix the
problem yourself, contact your installer and state the symptoms, the
complete model name of the unit (with manufacturing number if
possible) and the installation date.
