Test Run; The Following Phenomena Do Not Represent Faults; Information On Rating Plate - Mitsubishi Electric CITY MULTI PUHY-P-YJM-A serie Installationshandbuch

12. Test run

12.1. The following phenomena do not represent faults.

Phenomenon
Indoor unit does not perform cooling
(heating) operation.
The auto vane rotates and begins to blow air
horizontally.
Fan setting changes during heating.
Fan stops during heating operation.
Fan does not stop while operation has been
stopped.
No setting of fan while start SW has been
turned on.
Indoor unit remote controller shows "H0"
or "PLEASE WAIT" indicator for about five
minutes when turning ON universal power
supply.
Drain pump does not stop when unit is
stopped.
Drain pump continues to operate while unit
has been stopped.
Indoor unit emits noise when switching from
heating to cooling and vice versa.
Immediately after startup, the indoor unit
emits the sound of the refrigerant flow.
Warm air comes from an indoor unit that is
not performing a heating operation.

Cause
When another indoor unit is performing the heating (cooling) operation, the
cooling (heating) operation is not performed.
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.
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.
The fan is to stop during defrosting.
The fan is set to run for 1 minute after stopping to exhaust residual heat (only in
heating).
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).
The system is being started up.
Operate remote controller again after "H0" or "PLEASE WAIT" disappear.
After cooling operation stops, the unit continues to operate drain pump for
three minutes and then stops it.
Unit continues to operate drain pump if drainage is generated, even during a
stop.
This is a switching sound of the refrigerant circuit and does not imply a
problem.
Unstable flow of the refrigerant emits a sound. This is temporary and does not
imply a problem.
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.
