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 lters cause inefcient operation and waste energy.
Periodically clean the lter.
Recommended temperature setting
For cooling : 79°F – 82°F (26°C – 28°C)
For heating : 68°F – 72°F (20°C – 22°C)
Notes on the operating conditions
• The air conditioner always consumes a small amount 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.
• When the outdoor temperature is below 5°F (–15°C), turn on the
breaker more than 1 hour before starting the operation.
(This is to warm up the compressor.)
• Running the unit under conditions not listed below may cause the
safety device to activate, stopping the unit. Also, condensation may
form on the indoor unit and drip. (DRY/COOLING operation)
