8.3 OPERATING TEMPERATURE RANGES
Cool 61°F – 90°F (16°C – 32°C) 32°F – 131°F (0°C – 55°C)
Heat 32°F – 90°F (0°C – 32°C) 5°F – 86°F (-15°C – 30°C)
Dry 50°F – 90°F (10°C – 32°C) 32°F – 122°F (0°C – 50°C)
• 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.
• The remote control cannot be used to turn on the COOL function when
the ambient temperature is below 60°F (16°C). In this instance, use the
MANUAL CONTROL button to test the COOL function. (See section 9.6)
8.4 OPTIMAL OPERATION
To achieve optimal operating performance, please note the following:
• DO NOT put any objects near the air inlets/outlets. Doing this will impair performance
and could cause the unit to shut down.
• Adjust the airflow direction so it is not blowing directly onto personnel or at an extreme
angle.
• Adjust the temperature to achieve moderate comfort levels. An excessively low or high
temperature setting wastes energy.
• Keep windows and doors closed to improve performance.
• Limit energy usage (run time) using the TIMER function.
• Inspect the air filters periodically and clean them as needed.
