Ground Pin Installation
After determining placement use a post hole digger and dig a hole approximately 12-16” deep and 8 “diameter.
***WARNING*** – PRIOR TO DIGGING CONFIRM NO UNDERGROUND UTILITY LINES ARE PRESENT. STRIKING ANY UTILITY LINE COULD CAUSE PROPERTY DAMAGE, INJURY, OR DEATH. BEST PRACTICE IF YOU ARE UNSURE IS TO CONTACT LOCAL UNTILITY PROVIDER, (gas, water, electric) FOR LINE LOCATIONS. THIS SERVICE IS USUALLY AVAILABLE THROUGH YOUR UTILITY PROVIDER OR CITY/COUNTY INSPECTORS.
Mix fast-setting concrete per mfg. direction and fill the hole to within 1 inch of the top of the ground. Immediately insert provided ground pin in the center of the hole such that the cross pin is slightly above the concrete. Use a provided torpedo level to plumb the ground pin on opposite sides. This is important as you want the ground pin to be plumb (vertically) all around. If not, this could affect the wind wheel performance.
Allow full cure before final installation. Although the fast curing instructions may indicate full cure in a very short time it is recommended to wait 24 hours before completing installation.
