3.2.4 The horizontal adjustment of the indoor unit 
(1) Make sure that the hanger bracket is fixed by the nuts 
and the washers.
(2) Adjust the height of the unit.
(3) Check if the unit is positioned horizontally.

Fig. 3.7

(4) After the adjustment, tighten the nuts and swear  
the thread locker on the suspension to prevent the 
nuts from loosening.

(1) During the installation, please cover the unit with the 
plastic cloth to keep it clean.
(2) Make sure that the unit is installed level by using a level or 
a plastic tube filled with water in instead of a level, adjust the 
top surface of the unit to the surface of the water at both ends 
of the plastic tube and adjust the unit horizontally.(one thing to 
watch out for in particular is if it is installed so that the slope is 
not in the direction of the drain piping, as this might cause 
leaking.)
