Bolting the Outdoor Unit to the Platform Procedure
When installing the outdoor unit onto a concrete or rigid mount, use
a bolt and nut.
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 con-
densate 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
parts sand, and four parts gravel.
• The surface of the foundation should be finished with mortar with
rounded edges, and weatherproofed.
• All referenced materials are to be field-supplied.
• Images are not to scale.
