7. CARE AND CLEANING METHOD
Be sure to stop the operation of the unit with the
power switch and turn off the power (i.e., turn off
the earth leakage breaker) before starting the
maintenance of the unit.
CAUTION
Do not touch the aluminium fin directly at the
time of cleaning.
Doing so may result in injury.
Do not wash the unit with water.
Doing so may result in electric shock or ignition.
Be sure to stop the operation of the unit and
turn off the power circuit breaker at the time
of cleaning, maintenance and inspection.
Otherwise, electric shock or injury may result.
Cleaning the outdoor unit
• Consult your local dealer.
Cleaning the indoor unit
• As the system is an all-in-one air-conditioner and
refrigerator, the fan may rotate in a heating mode
even if operation is stopped with the remote con-
troller.
Be sure to stop operation with the remote control-
ler and cut off the power breaker before cleaning.
Refer to the operation manual attached to the
indoor unit for details.
Cleaning the showcase and the unit cooler
• Refer to the operation manual attached to the
showcase and the unit cooler for details.
Cleaning the drain pan (Optional accessory)
• Clean the drain pan so that it does not become
clogged and dusty.
• Turn off the power (i.e., turn off the earth leakage
breaker) if the unit is not used for a long time.
8. TROUBLESHOOTING
8-1 The following cases are not malfunc-
tions.
1. The unit does not operate.
•
The air conditioner does not start immedi-
ately when restart the operation after stop
the operation or change operation mode
after set the operation mode.
If the operation lamp lights, the system is in
normal condition.
To prevent overloading of the compressor
motor, the air conditioner starts 5 minutes after
it is turned ON again in case it was turned OFF
just before.
•
If “Centralized Control” is displayed on the
remote controller and pressing the opera-
tion button causes the display to blink for a
few seconds.
This indicates that the central device is control-
ling the unit.
The blinking display indicates that the remote
control cannot be used.
•
The system does not start immediately
after the power supply is turned on.
Wait one minute until the micro computer is
prepared for operation.
2. It stops sometimes
•
The remote controller display reads “U4” or
“U5” and stops but then restarts after a few
minutes.
This is because the remote control is intercept-
ing noise from electrical appliances other than
the air conditioner, and this prevents communi-
cation between the units, causing them to stop.
Operation automatically restarts when the
noise goes away.
3. COOL/HEAT cannot be changed over.
•
When the display shows “
”
(changeover under control).
It shows that this is a slave remote controller.
Refer to “Setting the master remote controller”.
•
When the cool/heat selector switch is
installed and the display shows
“
” (changeover under control).
This is because cool/heat changeover is con-
trolled by the cool/heat selector. Ask your
Daikin dealer where the remote control switch
is installed.
4. Fan operation is possible, but cooling and
heating do not work.
•
Immediately after the power is turned on.
The micro computer is getting ready to oper-
ate.
Wait 10 minutes.
5. The fan strength does not correspond to the
setting.
•
The fan strength does no change even if the
fan strength adjustment button in pressed.
During heating operation, when the room tem-
perature reaches the set temperature, the out-
door unit goes off and the indoor unit changes
to whisper fan strength.
This is to prevent cold air blowing directly on
occupants of the room.
The fan strength will not change even if the but-
ton is changed, when another indoor unit is in
heating operation.
