SLEEP
button
Pressing the
SLEEP
button will initiate the sleep mode. In this mode, the selected temperature will
increase by 2°F from the set temperature 30 minutes after the mode is selected. The temperature
will then increase by another 2°F after an additional 30 minutes (total of 4°F). This new temperature
will be maintained for 7 hours before it automatically returns to the originally selected temperature.
This ends the
SLEEP
mode and the unit will continue to operate as originally programmed. The
SLEEP
mode program can be cancelled at any time during operation by pressing the
SLEEP
button again.
SWING
button
This button is used to initiate the Auto swing feature which adjusts the airflow louvers. The function
can be stopped at any time by pressing the SWING button again to stop the louver at the desired angle.
Pressing the SWING button
for 3 seconds
will initiate the filter feature. This function is a reminder to
clean the Air Filter for more efficient operation. The LED (the light above the button) will illuminate
after 250 hours of operation as reminder to service or replace the filter.

resolve the error, disconnect the power, and then reconnect it. Turn the unit on. If the problem persists,
disconnect the power and contact your nearest customer service center. Error codes will appear and
begin with the letters, listed below, in the window display of indoor unit:
EH(xx), EL(xx), EC(xx) , PH(xx), PL(xx), PC(xx)

turn o

If the unit turns off unexpectedly due to a power outage, it will restart with the last function
setting/selection automatically when the power resumes.
ADDITIONAL THINGS YOU SHOULD KNOW
Now that you are familiar with the operating procedure, there are more features you should become
familiar with.
• The Cool circuit has an automatic 3 minute time delay before restarting if the unit is turned off and on
quickly. This prevents the compressor from overheating and possibly tripping the circuit breaker. The fan
will continue to run during this time.
• The LED display is capable of displaying temperature in Fahrenheit or Celsius. To convert from one reading
to the other, press and hold the Up and Down buttons together for 3 seconds.
