I had installed a brand new wall mounted type air conditioner - Fujitsu ASU18CL. But when I turn it on, the air is cool and very humid up to 68% humidity.
Is there someone who ever had this problem.

I just purchased an alleged "window mount" air conditioner with the closest dimensions to the existing model. Do these mount as through the wall as well? My current opening = 18 x 26" the new purchase is 16 27/32 x 26. There are 2 different types of window air conditioners – there are the window type of which will fit in a window that opens top to bottom and there is the slide in model of which the actual air conditioner will slide into a metal sleeve which is very common in apartments. In either case you need to measure the inside of the metal sleeve and then give that to the air conditioner dealer and he will know what to do and there is also a POS (point of sale) @ the store of which will also assist you in the measurement of the A/C unit – the window unit you need to measure the opening of the window itself, I hope this was helpful
An air conditioner of this type always has standing water sitting in the base-tray of the machine as it's running. They're designed to work that way.
However, if the unit leans slightly in toward the inside of your house, then the water in the tray can be deeper than it should and/or add extra humidity to the inside air.
These units are designed to be installed so that they lean slightly to the _outside_ of the window or wall-hole where they are mounted. This way the standing water drains off to the ground outside and isn't so deep on the inside of the unit that it adds too much humidity to the inside air.
Check the mounting of this unit to make sure it leans slightly toward the outside. Also verify that any notch or drain hole on the outside end of the unit, intended to guide draining water, is not clogged with debris (which could also cause the standing water in the unit to be at too high a level).
Also verify that the "vent" is closed, if this unit is equipped with said vent opening. An open vent panel can allow humid outside air inside as the unit is running.
Hope this helps! ;)
during Cooling and Dry modes, if the unit is used under conditions of lower temperature (18C) the heat-exchanger may freeze, leading to water leakage and other damage. If the unit is used for long periods under high-humidity conditions, condensation may form on the surface of the indoor unit, and drip onto the floor or other objects underneath. (About 80% or more)
