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.
Concrete Platform Specifications
• concrete foundations should be made of one part cement, two
