4.1 ODU Foundation
The concrete foundation of the ODU must be strong enough. Ensure that the drainage is smooth
and that the ground drainage or floor drainage is not affected.
Requirements on the concrete foundation are as follows:
1) The concrete foundation must be flat and have enough rigidity and strength to undertake the
unit’s weight during running. The height of the foundation is 200mm to 300mm, which is
determined based on the size of the unit.
2) Build a drainage ditch around the foundation to discharge the condensate water.
3) If the air conditioner is installed on the roof, check the intensity of the building and take
waterproof measures.
4) If a u-steel foundation is adopted, the structure must be designed with sufficient rigidity and
strength.
