2 persons should work together to put the air conditioner into the window opening so the bottom
of the air conditioner frame is against the windowsill.
Upper guide rail stays at the middle lower side of window and then window can stick to the upper
guide rail when closing it.
Please note that the air conditioner should be placed at horizontal place or inclined outwards
slightly. Carefully close the window behind the top rail of the unit.
Check that air conditioner is tilted back about 1/4” to 1/2” (6.35 mm - 12.7 mm) (tilted about 3°
downward to the outside, see Figure 7A and Figure 7B). After proper installation, condensate
should not drain from the overflow drain hole during normal use, correct the slope otherwise.
