1.4 Foundation for installation
A solid base can: Prevent the outdoor unit from sinking and avoid abnormal noise generated due to a lack
of base stability.
Base types: Steel structure base or concrete base (See the figure below for the general making method)
Note: The key points for base:
The master unit’s base must be made on solid concrete ground. Refer to the structure diagram to make concrete base, or
make after field measurements.
In order to ensure contact points are equally secure, the base should be completely level.
If the base is placed on a roof, the detritus layer isn’t needed, but the concrete surface must be flat. The standard concrete
mixture ratio is cement 1/ sand 2/ carpolite 4, and adds 10mm strengthen reinforcing steel bar, the surface of the cement
and sand plasm must be flat, border of the basement must be chamfer angle.
Before construct the unit base, please ensure the base is directly supporting the rear and front folding edges of the bottom
panel vertically, for the reason of these edges are the actual supported sites to the unit.
In order to drain off the seeper around the equipment, a discharge ditch must be setup around the basement.
Please check the affordability of the roofing to ensure the load capacity.
When piping from the bottom of the unit, the base height should be no less than 200mm.
