3.7 Factory-Preferred Tie-Down Method
INSTRUCTIONS
IMPORTANT:
These instructions are intended as a guide to securing equipment for
wind-load ratings of “120 MPH sustained wind load” and “3-second, 150 MPH gust.”
While this procedure is not mandatory, the Manufacturer does recommend that
equipment be properly secured in areas where high wind damage may occur.
STEP 1: Before installing, clear pad of any dirt or debris.
IMPORTANT:
The pad must be constructed of industry-approved materials,
and must be thick enough to accommodate the concrete fastener.
STEP 2: Center base pan on pad, ensuring it is level.
STEP 3: Using basepad as a guide, mark spots on concrete where 4 holes will be
drilled (see Figure 3).
STEP 4: Drill four pilot holes in pad, ensuring that the hole is at least 1/4” deeper
than the concrete screw being used.
STEP 5: Center basepan over pre-drilled holes and insert concrete screws.
STEP 6: Tighten concrete screws.
NOTE:
Do not over-tighten the concrete screws. Doing so can weaken the
integrity of the concrete screw and cause it to break.
STEP 7: Finish unit assembly per unit’s installation instructions.
