Bolting the Outdoor Unit to the Platform
1. Ensure that the concrete platform will not degrade easily, and has enough
strength to bear the weight of the unit.
2. Include an H-beam support. Firmly attach the corners, otherwise the support will
bend.
3. Use a hexagon nut.
4. Use anti-vibration material.
5. Include enough space around the concrete foundation for condensate
drainage.
6. Seal all wiring and piping access holes to prevent bugs from entering the unit.
Figure 244: Outdoor Unit Foundation Requirements.
Concrete Platform Specifications
• Concrete foundations should be made of one part cement, two
parts sand, and four parts gravel.
• The surface of the foundation should be finished with mortar with
rounded edges, and weatherproofed.
