6 AUTOMATIC CONTROLS
The system is equipped with the following functions.
THREE MINUTE GUARD
¡
The compressor remains off for at least 3 minutes once it has
stopped. If the system is started within approximately 3 minutes after
it has stopped, the RUN indicator is activated. However, the cooling
operation or the heating operation remains off and does not start
until after 3 minutes has elapsed.
Operation may stop for 6 minutes maximum to protect compressor.
FROST PREVENTION DURING COOLING OPERATION
¡
When the system is operated in a low temperature room, the cooling
operation may be changed to fan operation for a while to avoid frost
formation on the indoor heat exchanger.
AUTOMATIC RESTART AFTER POWER FAILURE
¡
If the power supply is interrupted for short periods of time (up to 2
seconds) the Remote Control switch will retain the settings and the
unit will restart when the power is restored.
If Automatic Restart is required after periods of lost power supply
in excess of 2 seconds please contact your distributor (optional
function).
7 BASIC TROUBLESHOOTING

system and contact your contractor.
THIS IS NOT ABNORMAL
¡
Sound from deforming Part
−
During system starting or stopping, and abrading sound might be
heard. However, this is due to thermal deformation of plastic parts.
It is not abnormal.
Refrigerant Flow Sound
−
While the system is being started or stopping, sound from the
refrigerant flow may be heard.
Smells from Indoor Unit
−
Smell adheres on indoor unit after a long period of time. Clean the
air filter and panels or make a good ventilation.
Steam from Outdoor Heat Exchanger
−
During defrosting operation, ice on the outdoor heat exchanger is
melted, resulting in making steam.
Dew on Air Panel
−
When the cooling operation continues for a long period of time
under high humidity conditions (higher than 27°C DB/80% R.H.),
dew can form on the air panel.
Dew on Cabinet
−
When the cooling operation continues for a long period of timer
(higher than 27°C DB/80% R.H.), dew can form on the cabinet.

switch, frosting on the outdoor unit is checked and the defrosting
operation may be performed for the maximum of 10 minutes.
PREVENTION OF OVERLOAD OPERATION
¡
When the outdoor temperature is too high during heating operation,
heating operation is stopped due to activation of the outdoor
thermistor until the temperature becomes low.
HOT START DURING HEATING OPERATION
¡
To prevent cold air discharge, the fan speed is controlled from
the slow position to the set position according to the discharge air
temperature. At this time the lover is fixes horizontally.
NO OPERATION
¡
Check whether the SET TEMPERATURE is set at the correct
temperature.
NOT COOLING WELL OR HEATING WELL
¡
Check for obstruction of air flow of the outside or inside units.
−
Check if too much heat source exists in the room.
−
Check if the air filter is clogged with dust.
−
Check to see if the doors or windows are opened or not.
−
Check if the temperature condition is not within the operating
−
range.
ABNORMAL SWING LOUVER'S POSISTION
