OPERATION

Observe the following precautions to ensure the system operates
properly.

Adjust the air outlet properly and avoid direct air flow to room
inhabitants.

Adjust the room temperature properly for a comfortable
environment. Avoid excessive heating or cooling.

Prevent direct sunlight from entering a room during cooling
operation by using curtains or blinds.

Ventilate often.
Extended use requires special attention to ventilation.

Keep doors and windows closed. If the doors and windows
remain open, air will flow out of your room causing a decrease in
the cooling or heating effect.

Be careful not to cool or heat too much. To save energy, keep
the temperature setting at a moderate level.

Never place objects near the air inlet or the air outlet of the unit.
It may cause deterioration in the effect or stop the operation.

Turn off the main power supply switch to the unit when the unit is
not used for longer periods of time. If the switch is on, it uses
electricity. Before restarting the unit, turn on the main power
supply switch 6 hours before operation to ensure smooth
running. (Refer to "Maintenance" in the indoor unit manual.)

When the display shows 

 (time to clean the air filter), ask a

qualified service person to clean the filters. (Refer to
"Maintenance" in the indoor unit manual.)

Keep the indoor unit and remote control at least 1 m away from
televisions, radios, stereos, and other similar equipment.
Failing to do so may cause static or distorted pictures.

Do not place items under the indoor unit which may be damaged
by water.
Condensation may form if the humidity is above 80% or if the
drain outlet gets blocked.

Maintenance after a long stop period 

(e.g. at the

beginning of the season)

Check and remove everything that might be blocking inlet and
outlet vents of indoor units and outdoor units.

Clean air filters and casings of indoor units. Refer to the
operation manual supplied with the indoor units for details on
how to proceed and make sure to install cleaned air filters back
in the same position.

Turn on the power at least 6 hours before operating the unit in
order to ensure smoother operation. As soon as the power is
turned on, the remote controller displays appear.

8.2.

Maintenance before a long stop period 

(e.g. at

the end of the season)

Let the indoor units run in fan only operation for about half a day
in order to dry the interior of the units. Refer to 

"6.1. Cooling,

heating, fan only, and automatic operation" on page 3

 for details

on fan only operation.

Turn off the power. The remote controller displays disappear.

Clean air filters and casings of indoor units. Refer to the
operation manual supplied with the indoor units for details on
how to proceed and make sure to install cleaned air filters back
in the same position.

CONDITIONER

 

TROUBLES

Symptom 1: The system does not operate

The air conditioner does not start immediately after the ON/OFF
button on the remote controller is pushed.
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. The same starting delay occurs
after the operation mode selector button was used.

If "Centralized Control" is displayed on the remote control and
pressing the operation button causes the display to blink for a
few seconds.
This indicates that the central device is controlling 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.

Symptom 2: Cool/Heat cannot be changed over

When the display shows "

" (change-over under

centralized control), it shows that this is a slave remote
controller.

When the cool/heat changeover remote control switch is
installed and the display shows "

" (change-over under

centralized control).
This is because cool/heat changeover is controlled by the cool/
heat changeover remote control switch. Ask your dealer where
the remote control switch is installed.

NOTE

Contact your dealer in case of changing the
combination or setting of group control and two remote
controller control systems.

Recommended temperature setting

For cooling

26~28°C

For heating

20~24°C

Pay attention to the fan.

It is dangerous to inspect the unit while the fan is running.
Be sure to turn off the main switch and to remove the fuses
from the control circuit located in the outdoor unit.
