12. Test run
12.1. The following phenomena do not represent faults.
Phenomenon Display of remote controller Cause
Indoor unit does not perform cooling
(heating) operation.
“Cooling (heating)” ashes When another indoor unit is performing the heating (cooling) operation, the
cooling (heating) operation is not performed.
The auto vane rotates and begins to blow air
horizontally.
Normal display If air has been blowing downward for 1 hour during cooling, the unit may
automatically change to horizontal blowing with the control operation of the
auto vane. During defrosting or immediately after heating start-up/shut-down,
the auto vane automatically rotates to blow air horizontally for a short period
of time.
Fan setting changes during heating. Normal display Ultra-low speed operation is commenced at thermostat OFF.
Light air automatically changes over to set value by time or piping temperature
at thermostat ON.
Fan stops during heating operation. Defrost display The fan is to stop during defrosting.
Fan does not stop while operation has been
stopped.
No lighting
The fan is set to run for 1 minute after stopping to exhaust residual heat (only in
heating).
No setting of fan while start SW has been
turned on.
Heat ready Ultra low-speed operation for 5 minutes after SW ON or until piping
temperature becomes 35°C, low speed operation for 2 minutes thereafter, and
then set notch is commenced (Hot adjust control).
Indoor unit remote controller shows “H0”
or “PLEASE WAIT” indicator for about ve
minutes when turning ON universal power
supply.
“H0” or “PLEASE WAIT” ashes The system is being started up.
Operate remote controller again after “H0” or “PLEASE WAIT” disappear.
Drain pump does not stop when unit is
stopped.
Light out After cooling operation stops, the unit continues to operate drain pump for
three minutes and then stops it.
Drain pump continues to operate while unit
has been stopped.
Unit continues to operate drain pump if drainage is generated, even during a
stop.
Indoor unit emits noise when switching from
heating to cooling and vice versa.
Normal display This is a switching sound of the refrigerant circuit and does not imply a
problem.
Immediately after startup, the indoor unit
emits the sound of the refrigerant ow.
Normal display Unstable ow of the refrigerant emits a sound. This is temporary and does not
imply a problem.
Warm air comes from an indoor unit that is
not performing a heating operation.
Normal display The LEV is slightly open to prevent refrigerant, of the indoor unit that is not
performing the heating operation, from being liqueed. This does not imply a
problem.
