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 airflow louver to
its maximum angle, 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 or disable.
Optimal Operation
To achieve optimal performance, please note the
following:
DO NOT put any objects near the air inlets &
outlets. Doing this would impair performance and
could cause the unit to shut down.
• Adjust the airflow direction of the louvers
correctly, so that it is not towards people or at an
extreme angle/closed.
• Adjust the temperature to achieve moderate
comfort levels. An excessively low or high
temperature setting wastes energy.
• Keep windows and doors closed, as this will
improve performance.
• Limit energy usage (run time) using the TIMER
function and SLEEP/ECONOMY mode if applicable.
• Inspect and clean the air filter every two weeks.
Doors and windows
should be kept
closed.
Closing the curtains
while heating also
helps keep the heat in
CAUTION
DO NOT put your fingers into the panel of the blower and suction side. The high speed fan
inside may cause injury.
The table below represent the normal temperature ranges the unit is designed to operate in. If the unit is
operated outside of these ranges, certain safety protection features could activate and cause the unit to
disable or operate abnormally.
