If drain pipe running horizontal for long distance without any fall there may be build up of condensate.
Should be vertical fall from indoor unit before horizontal pipe run.

thanks unibar
the pipe run 2 meter horizental ,then it goes vertical to outside, in the manual it is noted to run the drain pipe with the refrigeration pipe, there is 2 opening in the indoor unit for running the pipes, one at left the other at right

However long the pipe there must be some fall or gradient along the length to allow the water to flow.

yes brian,you are right.
i ask civil engineer who works on sewages, she tell me it must be 1% slope, means 1cm. slope each 1m length of pipe, also i find in split catalogue; the hole in the wall must be sloped downwards 5-10mm, the drain pipe must not curved upwards. i will do by these instruction and inform you next few days.
all regards

Afeef, it depends on the appearance within the room but it sometimes improves drainage if the drain is taken verically down from the unit before turning to go through another hole lower down.

Mean more work - sorry.
