NOT MALFUNCTION OF THE AIR CONDI-
TIONER
The following symptoms do not indicate air conditioner mal-
function.
I. THE SYSTEM DOES NOT OPERATE
• 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 min-
utes, the system will turn on again automatically.
• The system does not restart immediately when TEM-
PERATURE SETTING button is returned to the former
position after pushing the button.
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 min-
utes, the system will turn on again automatically.
• The system does not start when the display shows
" " (UNDER CENTRALIZED CONTROL) and
it flashes for a few seconds after pressing an opera-
tion button.
This is because the system is under centralized control.
Flashes on the display indicates that the system cannot be
controlled by the remote controller.
• The system does not start immediately after the power
supply is turned on.
Wait at least 5 minute until the micro computer is prepared
for operation.
II. WHITE MIST COMES OUT OF A UNIT
• When humidity is high during cooling operation. (In
oily or dusty places)
If the inside of an indoor unit is extremely contaminated,
the temperature distribution inside a room becomes
uneven. It is necessary to clean the inside of the indoor
unit. Ask your dealer for details on cleaning the unit. This
operation requires a qualified service person.
• When the system is changed over to HEATING OPER-
ATION after DEFROST OPERATION.
Moisture generated by DEFROST becomes steam and exists.
III. NOISE OF AIR CONDITIONERS
• A ringing sound after the unit is started.
This sound is generated by the temperature regulator
working.
It will quiet down after about a minute.
• A continuous flow "Shuh" sound is heard when the
systems is in COOLING or DEFROST OPERATION.
This is the sound of refrigerant gas flowing through both
indoor and outdoor units.
• A "Shuh" sound which is heard at the start or immedi-
ately after the stop of operation or which is heard at
the start or immediately after the stop of DEFROST
OPERATION.
This is the noise of refrigerant caused by flow stop and
flow change.
• A continuous low "Shah" sound is heard when the
system is in COOLING OPERATION or at a stop.
The noise is heard when the drain pump is in operation.
• A "Pishi-pishi" squeaking sound is heard when the
system is in operation or after the stop of operation.
Expansion and contraction of plastic parts caused by tem-
perature change makes this noise.

tion from long resting time.
