Bolting the Outdoor Unit to the Platform
1. Ensure that the concrete platform will not degrade easily, and
has enough structural 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 con-
densate drainage.
6. Seal all wiring and piping access holes to prevent insects from
entering the unit.
