■ Tips for saving energy
• Be careful not to cool (heat) the room too much.
Keeping the temperature setting at a moderate level helps save energy.
• Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors increases the cooling
(heating) effect.
• Clogged air filters cause inefficient operation and waste energy. Clean them once in about every
two weeks.
■ Please note
• The air conditioner always consumes 15-35 watts of electricity even while it is not operating.
• If you are not going to use the air conditioner for a long period, for example in spring or autumn,
turn the breaker OFF.
• Use the air conditioner in the following conditions.
For combination with R410A outdoor unit refer to the following table:
For combination with R32 outdoor unit refer to the following table:
DB: Dry bulb temperature
WB: Wet bulb temperature
(a)
To avoid condensation and water dripping out of the unit. If the temperature or the humidity is beyond these
conditions, safety devices may be put in action and the air conditioner may not operate.
If operation is continued out of this range:
•
Operation outside this humidity or temperature range may cause a safety device to disable the system.
• A safety device may work to stop the operation. (In multi system, it may work to stop the operation
of the outdoor unit only.)
• Condensation may occur on the indoor unit and drip
