Precautions for Group Control System or Two Remote Controller Control System
This system provides two other control systems beside individual control (one remote controller controls one indoor unit) system.
Confirm which type of your unit is the following system.
•
Group control system
One remote controller controls up to 16 indoor units. All indoor units are equally set.
•
Two remote controller control system
Two remote controllers control one indoor unit (in case of group control system, one group of indoor units). The unit is
individually operated.
Note
• Contact your local dealer in case of changing the combination or setting of group control and two remote controller control systems.
Optimum Operation
Observe the following precautions to ensure the system operates properly.
• Prevent direct sunlight from entering a room during cooling operation by using curtains or blinds.
• Do not leave doors and windows open. If the doors and windows remain open, air will flow out of your room causing a
decrease in the cooling or heating effect.
• Do not use other heating devices directly beneath the indoor unit.
If you do, they might get deformed by the heat.
• 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.
• Adjust the room temperature properly for a comfortable environment. Avoid excessive heating or cooling.
• Ventilate often.
Extended use requires special attention to ventilation.
• Keep the indoor unit and remote controller at least 3.5ft. (1m) away from televisions, radios, stereos, and other similar equipment.
Failing to do so may cause static or distorted pictures.
• 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 the chapter “Maintenance” in the indoor unit manual.)
• Fully use the function of air flow direction adjust.
Cold air gathers on the floor, and warm air gathers in the ceiling.
Set the air flow direction parallel during cooling or dry operation, and set it downwards during heating operation.
Do not let the air blow directly to a person.
• It takes time for the room temperature to reach the set temperature.
We recommend starting the operation in advance using schedule operation.
Seasonal Maintenance
Caution
•
Touching them may result in injury.
•
Do not wash the outside or indoor units with water.
An electric shock or fire may result.
•
If the scaffold is unstable, you may fall or topple down, thus causing injury.
•
Be sure to stop the operation, and turn the breaker off before cleaning.
This may cause electric shock and injury.
•
Consult with the dealer for cleaning the interior of the indoor units.
Incorrect cleaning may damage the plastic parts and cause failures, such as water leakage, and an electric shock may result.
At the beginning of the season
Check
• Are the indoor and outdoor unit intake and outlet vents blocked?
Remove anything that might be blocking them.
Clean the exterior.
• See the Operation Manual included with the indoor unit for details on how to clean it.
Turn the power on.
• When the power comes on, the characters in the remote controller display appear.
(To protect the unit, turn the power on at least 6 hours before operating it. This makes operation smoother.)
At the end of the season
On a clear day, use fan operation for around half a day to thoroughly dry out the interior of the unit.
• This step is performed to prevent buildup of mold and other harmful organisms.
Turn off the power.
• When the power is shut off, the characters in the remote controller display disappear.
• When the power is on, the unit consumes up to several dozen Watts of power.
Turn off the power to conserve energy.
Clean the exterior.
• See the Operation Manual included with the indoor unit for details on how to clean it.
