System Configuration
•
If the operation mode does not match other indoor units
that are already running, the indoor unit will assume the
STANDBY state (the fan is stopped and the air flow flap is
positioned horizontally).
If HEATING mode is set together with COOLING, DRY or
FAN mode, the above mentioned condition will occur.
NOTE
•
Normally, the operation mode in the room where the unit is
first run is given priority, but the following situations are
exceptions, so please keep this in mind.
a. If the operation mode of the first room is FAN Mode,
then using Heating Mode in any room after this will give
priority to heating. In this situation, the air conditioner
running in FAN Mode wil go on standby.
b. With the Priority Room Setting active.
Contact your Daikin dealer for the operation that
corresponds to your system.
•
If the total capacity of operating indoor units exceeds the
limit, the indoor unit will assume the STANDBY state (FAN
and AIR FLOW DIRECTION will be left as set). (This only
applies to cooling only type.)
•
If another indoor unit commences a HEATING operation
after this indoor unit is running in COOLING mode, this
indoor unit may switch to DRY operation (fan on low, air
flow flap set at horizontal).
III. The fan speed is different from the setting.
•
Pressing the fan speed control button does not
change the fan speed.
When the room temperature reaches the set temperature
in heating mode, the power supply from the outdoor unit is
stopped and the indoor unit will operate on the low fan
setting. (If using the multi system, the fan will alternate
between off and low.)
This is to prevent the cool air from being blown directly
onto anyone in the room.
IV. Air blow direction is not as specified.
•
Actual air blow direction is not as shown on the
remote control.
•
Automatic swing setting does not work.
Refer to “AIR FLOW DIRECTION ADJUST.”
V.
White mist comes out of a unit
•
When humidity is high during cooling operation (In
oily of 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 Daikin dealer for details on cleaning the unit.
This operation requires a qualified service person.
•
When the system is changed over to HEATING
OPERATION after DEFROST OPERATION.
Moisture generated by DEFROST becomes steam and
exists.
VI. 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
system 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
immediately 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 flowing sound “Shah” or a trickling
sound “Jyuru Jyuru” are 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
temperature change makes this noise.
VII.Dust from the units
•
Dust may blow out from the unit after starting
operation from long resting time.
Dust absorbed by the unit blows out.
VIII.The units give off odors
The unit absorbs the smell of rooms, furniture, cigarettes,
etc., and then emits them.
IX. The liquid crystal of the remote control show “
88
”
•
It happens immediately after the main power supply
switch is turned on.
This shows that the remote control is in normal condition.
This continues temporary.
I. If one of the following malfunctions occurs, take the
measures shown below and contact your Daikin dealer.
The system must be repaired by a qualified service person.
When the air conditioner is in abnormal conditions
(smell of something burning, etc.), unplug the power
cord from the outlet, and contact your dealer
Continued operation under such circumstances may result
in a failure, electric shock, and fire.
•
If a safety device such as a fuse, a breaker, or an earth
leakage breaker frequently actuates, or ON/OFF switch
does not properly work.
Measure: Turn off the main power switch
•
If water leaks from unit.
Measure: Stop the operation.
