INSTALLATION STEP 2 CONCRETE PAD AND OPERATOR ATTACHMENT CHECK the national and local building codes before installation. NOTE: When lifting the operator use the handle to avoid damaging the operator. 1. Install the electrical conduit. 2. Pour a concrete pad (reinforced concrete is recommended). The concrete pad should be 6 inches above the ground and deeper than the frost line. Ensure the pad is tall enough to avoid possible flooding. 3. Secure the operator to the concrete pad with appropriate fasteners. NOTE: An alternative to a concrete pad is to post mount the operator (refer to accessories).
