Not Malfunction of the Air Conditioner
The following symptoms do not indicate air conditioner malfunction
I. THE SYSTEM DOES NOT OPERATE
z
The system does not restart immediately after the ON/OFF button is pressed.
If the OPERATION lamp lights, the system is in normal condition. It does not restart immediately
because a safety device operates to prevent overload of the system. After 3 minutes, the system will
turn on again automatically.
z
The system does not restart immediately when TEMPERATURE SETTING button is returned to
the former position after pushing the button.
It does not restart immediately because a safety device operates to prevent overload of the system.
After 3 minutes, the system will turn on again automatically.
z
If the reception beep is rapidly repeated 3 times (It sounds only twice when operating normally.)
Control is set to the optional controller for centralized control.
z
If the defrost lamp on the indoor unit’s display is lit when heating is started.
This indication is to warn against cold air being blown from the unit. There is nothing wrong with the
equipment.
II. THE UNIT STOPS ONCE IN A WHILE
z
The remote controller indicates “
U4
” and “
U5
”, the unit stops. Within several minutes the unit
restarts.
Due to electrical noise other than that from the air conditioner, the communication between the units is
cut off and the unit stops.
When the noise is gone, the unit automatically restarts.
III. NO CHANGEOVER IS AVAILABLE BETWEEN HEATING AND COOLING MODES
z
The indoor unit makes a “PEEE” receiving sound.
When operation changeover is under control, the control is set to the mode that cannot be carried out.
IV. AIR FLOW RATE CANNOT BE OBTAINED AS SET
z
Even if the air flow rate adjusting button is pressed, the air flow rate does not change.
When the room temperature reaches the indoor unit set temperature, the outdoor unit stops and the air
flow rate of indoor unit drops to the minimum.
This is to avoid the cold air from getting in contact with the people in the room.
V. AIR DISCHARGE DIRECTION IS NOT AS SET
z
The remote controller indication and the air discharge direction is not the same.
Air discharge direction swing is impossible.
Because it is controlled by microcomputer. Refer to “AIR FLOW DIRECTION ADJUST” on page 56.
VI. ONLY A PART OF INDICATION SHOWS
z
Even if the unit is operated, only the operation indication shows, or even if the indication shows,
soon after, the indication other than that for operation disappears.
The corresponding indoor unit is that for multi-system and the remote controller is set to the multi-
system.
VII.NO INDICATION SHOWS OR ALL INDICATION SHOW
z
When the remote controller button is pressed.
The battery is dead.
VIII.INSUFFICIENT COOLING
