2.5 Location
In order to obtain optimum efficiency and performance, and to prevent any f ailures or hazardous situation, the location must meet the following requirements: 1）For floor standing, the minimum distance between air outlet grille and other obje cts is 140mm. The distance from side pane l to the wall is no less than 20mm to make it e asy to remove the side panels. 2）For wall mounting, the unit should be mounted no less than 80mm higher than floor. 3）For ceiling installation, the unit needs to be at least 2.5m far away from the floor, and don't allow to blow the cold ai r to the body directly. The w all should be strong enough to support the unit. 4）The clearance between air inlet grille and other objects is around 400mm. the unit should lean a little bit(≤2 degrees) to the area of water discharge for good condensate discharge.

The condensate drainage system must be set up with
an adequate decline, to ensure the water drain away
properly. Following are directions for setting up a
proper condensate drainage system:
Notice:
it's commended to pour some water into the
drain pan very slowly. If the water can't
drain away smoothly, some adjustment
should be made.
