3.2.5 Diagram of installation 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 200 mm to 300 mm, which is
determined based on the size of the unit. If it is installed in place with large snowfall, increase
the height of the foundation so that the air inlet side is not buried by snow.
(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.
(5) Cement foundation diagram is shown as follows:
3.2.6 Shock absorption requirements
The outdoor unit should be firmly fixed. Thick rubber sheets or corrugated rubber damping rubber
mats with a thickness of 20mm at least and a width of 100mm at least should be placed between the
unit and the foundation. The installation requirements are shown as follows.
