CAUTION
DO NOT Do not put your fingers into the panel of 
the blower and suction side. The high speed fan 
inside may cause injury. 
DO NOT operate the unit for long periods of time 
with the airflow direction set downward in 
cooling or dehumidifying mode. Otherwise, 
condensation might occur on the surface of the 
vertical louver causing moisture to drop on to 
the floor or furnishings .
DO NOT move the vertical louver manually. 
Otherwise, the vertical louver will be out of sync. 
IF this happens, cease operation, turn off power 
to the unit, remove the wireless module from the 
front cover, turn off power to the circuit (at the 
breaker), wait for a few seconds and turn power 
back on at the breaker, reinstall wireless module 
and power the unit back on.
After a quick restart, the vertical louver may 
remain static for approximately 10 seconds. 
Open angle of the vertical louver should not be 
set too small, as it will restrict airflow and reduce 
COOLING and HEATING performance.
