•  Before you install the indoor unit, make sure that you remove 
the  buffers  used  for  transportation between  the fan  and  the 
pipe  socket  (see  Figure  3.9).  If  you  run  the  unit  without 
removing the buffers, you may damage the fan motor.
•  Make sure that the unit body is level; otherwise, it may cause 
water to leak. Calibrate the levelness of the unit using a spirit 
level or polyethylene tube filled with water.
•  The unit is equipped with a built-in water discharge pump and 
float switch. Do not tilt the unit in the direction of the drain pan; 
otherwise, the float switch may malfunction and cause water 
leakages.
