NOTE
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 fi lters cause ineffi cient operation and waste energy. Clean them once in about every two weeks.
Please note
•
The air conditioner always consumes 50-120 btu/h (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 condition er in the following conditions.
Mode Operating conditions
Outdoor temperature : 14 to 115°F (–10 to 46°C)

<Note 1> A Breaker must be turned on for 24 hours before the operation start if the ambient is below 14 °F (–10°C),
otherwise the unit will not start operation smoothly.
<Note 2> 1. Use low outdoor ambient COOL operation for equipment cooling applications only.
This operation is not intended for human comfort cooling.
2. Intermittent noises may be produced by the indoor unit due to the outdoor fan rotation speed change.
3. Do not place humidifi ers or other items which might raise the humidity in rooms at 0 to 14 °F (–10°C) outdoor
temperature. A humidifi er may cause condensation to drip from the indoor unit outlet vent.
4. Set the indoor unit at the highest airfl ow rate.
<Note 3> When the outdoor temperature is 0 to 5 °F (–18 to –15°C), the system may not have suffi cient cooling capacity.
