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)” flashes
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 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 “HO”
or “PLEASE WAIT” indicator for about five
minutes when turning ON universal power
supply.
“HO” or “PLEASE WAIT”
flashes
The system is being started up.
Operate remote controller again after “HO” or “PLEASE WAIT” disappears.
Drain pump continues to operate even after
the unit has been turned off.
No display
After turning off the cooling operation, unit continues to operate the drain
pump for 3 minutes, then shuts it off.
Unit also continues to operate drain pump if condensate has been generated.
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 flow.
Normal display
Unstable flow 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 liquefied. This does not imply a
problem.
