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 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 five

minutes when turning ON universal power

supply.

“H0” or “PLEASE WAIT” flashes

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 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.
