11-4. Operation check
The following symptoms are normal and do not indicate a problem.
Events
Display on
remote
controller
Cause
A specific indoor unit is not performing the
cooling or heating operation.
"Cool" or "Heat"
blinks.
Other indoor units in the same refrigerant system are already operated in a
different mode.
The auto vane automatically switches air
flow direction.
Normal display
The auto vane may switch over to horizontal air flow operation from vertical air flow
operation in cooling mode if the vertical air flow operation has been running for one
hour. At defrost in heating mode or immediately after heating start-up/shutdown,
the auto vane automatically switches to horizontal air flow for a short time.
The fan speed automatically changes
during heating operation.
Normal display
The fan operates at Very Low speed when the thermostat is turned off, and
automatically changes over to the preset speed according to the timer setting or
refrigerant temperature when the thermostat is turned on.
The fan stops during heating operation.
"Defrost"
The fan remains stopped during the defrost cycle.
The fan keeps running after the unit has
stopped.
No display
After the unit has stopped during heating operation, the fan operates for one
minute to exhaust heat.
At the beginning of heating operation, the
fan cannot be manually set.
"Stand By"
The fan operates at Very Low speed for five minutes after heating operation starts
or until the refrigerant temperature reaches 35°C (95°F), then the fan operates at
Low speed for two minutes, and finally the fan operates at the preset speed.
When the main power is turned on, the
display as shown right appears on the
remote controller for about five minutes.
"H0" or
"PLEASE WAIT"
blinks.
The system is starting up. Wait until "HO" or "PLEASE WAIT" stops blinking and
goes off then try again.
The drain pump keeps running after the
unit has stopped.
No display
The drain pump remains in operation for three minutes after the unit in cooling
mode has stopped.
The drain pump goes into operation when drain water is detected, even when the
unit is stopped.
The indoor unit emits noise when
switching from heating to cooling and vice
versa.
Normal display
This is a normal sound of the refrigerant circuit operating properly.
Immediately after startup, the indoor unit
emits the sound of refrigerant flowing.
Normal display
Unstable flow of the refrigerant produces a sound. This is temporary and does not
imply a problem.
Warm air comes from an indoor unit that
is not performing the heating operation.
Normal display
The LEV is slightly open for preventing any refrigerant, inside of the indoor unit that
is not performing the heating operation, from being liquefied. This does not imply a
problem.
