The following precautions must be taken when installing the split-air conditioner evaporator units:

Select a location with sufficient space to allow general repairs or maintenance, such as cleaning the air filter.
The minimum spaces presented
 Ensure that the unit is level and horizontally inclined to ensure perfect water flow. •
 A minimum floor height.
 In a place that respects the distances around the internal unit, according to
 (at a free distance greater than 15 cm from the ceiling and 12 cm from the sides).
Make sure that the wall surface is sufficiently flat so as to allow easy and safe installation. The wall structure must be suitably strong to support the weight of the unit and avoid deformation, rupture or vibration during operation.
If there is more than one appliance in the room, make sure that the air
one does not interfere with the flow of the other so as not to create abnormal
operation.
Also avoid installation of appliances that are too close together.
 Direct exposure to sunlight.
 Proximity of heat sources.
 Wet walls or places where there is danger of contact with a lot of water or steam,
for example, laundries.
 Locations with steam and oil (eg kitchens, machine shops).
 Places where curtains or furniture prevent the free circulation of air.
