NOTES:
• If the air conditioner operates for extended periods in cooling mode and the humidity
is high (over 80%), condensed water may drip out of the unit. If this occurs, set the vertical
airflow louver to its maximum angle (vertical toward the floor), and set it to HIGH fan mode.
• Optimum performance will be achieved within the above operating temperatures. If the air
conditioner is operated outside of the above temperatures, certain safety protection features
might be activated and cause the unit to function abnormally.
• FOR OUTDOOR UNITS WITH AUXILIARY ELECTRIC HEATER: When the outside temperature
is below 32°F (0°C), we strongly recommend keeping the unit plugged in at all time to ensure
smooth ongoing performance.
