Make sure that the wall surface is flat enough 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 environment, make sure that one airflow does not interfere with the other's flow so as not to create abnormal operating conditions.
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).
