To further optimize the performance of your unit, do the following:
Keep doors and windows closed.
Limit energy usage by using TIMER ON and TIMER OFF features.
Do not block air inlets or outlets.
Regularly inspect and clean air filters.
NOTE
Keep the room's relative humidity below 80%. If the air conditioner operates in excess
of this, the surface of the air conditioner may attract condensation. To help prevent
condensation from forming and dripping, set the vertical airflow louver to its maximum
angle (vertically to the floor) and set the fan to HIGH.
NOTE
Your Durastar air conditioner's outdoor unit is equipped with a base pan heater, allowing
it to continue to operate at freezing temperatures as low as -13°F (-25°C). When outdoor
air temperatures are at or below 32°F (0°C), we strongly recommend keeping the unit
plugged in at all times to ensure smooth ongoing performance.
