18 Troubleshooting
If one of the following malfunctions occur, take the measures shown
below and contact your dealer.
WARNING
Stop operation and shut off the power if anything
unusual occurs (burning smells etc.).
Leaving the unit running under such circumstances may
cause breakage, electric shock or fire. Contact your dealer.
The system must be repaired by a qualified service person:
Malfunction Measure
If a safety device such as a fuse, a
breaker or an earth leakage breaker
frequently actuates or the ON/OFF
switch does not properly work. Turn off the main power
switch.
If water leaks from the unit. Stop the operation.
The operation switch does not work
well. Turn off the power.
If the user interface display indicates the
unit number, the operation lamp flashes
and the malfunction code appears. Notify your installer and
report the malfunction
code.
If the system does not properly operate except for the above
mentioned cases and none of the above mentioned malfunctions is
evident, investigate the system according to the following
procedures.
Malfunction Measure
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.
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 (see
"17.1.1 To clean the air filter" on
page 27
).
▪ 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.
If after checking all above items, 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 (possibly listed on the warranty card).
